Fluoroquinolones (FQs) are widely used for their excellent antimicrobial properties, yet their release into aquatic environments pose risks to ecosystems and public health. The accurate monitoring and analysis of FQs present challenges due to their low concentrations and the complex matrices found in actual environmental samples. To address the need for auto-pretreatment and on-line instrumental analysis, developing new microextraction materials and protocols is crucial. Such advancements will provide better analytical assurance for the effective extraction and determination of FQs at trace levels, which is of great significance to environmental protection and human health. In this work, we presented a Co2+ mediated paper-based molecularly imprinted polymer chip (CMC@Co-MIP), combined with UPLC analysis, to develop an effective analytical method for identifying and quantifying trace amounts of ciprofloxacin (CIP) and enrofloxacin (ENR) in water samples. Notably, the addition of Co2+ in CMC@Co-MIP helped to capture the template molecule CIP through coordination before imprinting, which significantly improved the ordering of the imprinted cavities. CMC@Co-MIP exhibited a maximum adsorption capacity up to 500.20 mg g−1 with an imprinting factor of 4.12, surpassing previous reports by a significant margin. Furthermore, the enrichment mechanism was extensively analyzed by various characterization techniques. The developed method showed excellent repeatability and reproducibility (RSD < 13.0 %) with detection limits ranging from 0.15 to 0.21 μg L−1 and recoveries ranging from 64.9 % to 102.3 % in real spiked water samples. We developed a novel microextraction paper-based chip based on Co2+ mediation, which effectively improved the selectivity and convenience of extracting FQs. This breakthrough allowed the chip to have a high enrichment efficiency as well as provide a robust on-line instrumental program. It also confirms that the imprinting scheme based on metal ion coordination is a high-performance strategy. [Display omitted] • A novel paper-based molecularly imprinted polymer chip (CMC@Co-MIP) was synthesized. • The imprinting protocol based on metal coordination was a high-performance strategy. • The chip showed excellent adsorption of fluoroquinolones, reaching 500.20 mg g−1. • The chip exhibited potentiality for environmental water samples pretreatment.

Honey peach (Prunus persica) is easy to rot after picking because of its special property, and the damage of traditional preservation method to the ecological environment is unacceptable. Therefore, chitosan as a kind of environmental protection material with excellent performance has attracted people's attention. Though chitosan has good practicability, its application in practical production is limited due to its poor water solubility. In this study, we prepared phenolic acid- g -chitosan using two synthesis methods of carbodiimide-mediated coupling reaction and free radical-mediated grafting procedure. After comparing the grafting rates of these conjugates, the results showed that using the synthetic method of carbodiimide-mediated coupling reaction through NHS and EDC as the coupling agent to graft phenolic acid onto chitosan had a good grafting ratio at a molar ratio of 1.5:1. Therefore, six phenolic acids were used for the first time to prepare conjugates through this method, and these conjugates were characterized by UV and NMR. It can significantly improve the water solubility and DPPH scavenging activity of chitosan, thus releasing its good properties and meeting the application of post-harvest preservation of honey peaches. The results indicate the antisepsis and fresh-keeping effects of six conjugates showed that preservative paper containing 2-Hydroxyphenylacetic acid- g -CS has the best effect of inhibited decay index and weight loss when peach fruits were stored at 20 ± 5 °C under 40%–60% humidity for 8 days. Thus, the water-soluble conjugate prepared by grafting phenolic acid onto chitosan can enhance the market application range of chitosan. [ABSTRACT FROM AUTHOR]

The potential health and environmental impacts associated with the improper management of chemically treated wood waste demands the adoption of recycling, and disposal practices. Chemically treated wood waste has several physical and chemical properties which makes it usable for the manufacture of another product to multiple use, among which the production of paper and fuel. This paper presents the initial life cycle assessment (LCA) study on wood waste used for paper production. The study boundary is limited with raw materials (raw wood or waste wood) processing and paper production itself, thus corresponds to “gate-to-gate” life cycle with a special focus on life cycle inventory data on waste wood treatment via hydrolysis process. The results of the analysis demonstrate competitiveness of the waste wood use for paper production vs. raw wood in such environmental categories as human health and ecosystem quality.

[Display omitted] • GQD-DDT and GQD-MPA was synthesized using novel hydrothermal protocol. • GQD-DDT and GQD-MPA was used for the identification of cations using colorimetric and spectrophotometric assay. • GQD-DDT and GQD-MPA have well activity for ion sensing in aqueous solution. This study describes the synthesis of various types of thiolated-graphene quantum dots (GQDs) for the simultaneous multi-sensing of heavy metal ions using one-droplet microfluidic paper-based analytical devices (OD- µ PADs). For the first time, functionalized GQDs were synthesized and stabilized on the surface of hydrophobic fiber-glass with simple manufacturing and assembly strategy towards colorimetric chemosensing of ions including iron, copper, cobalt, mercury, chrome, manganese, and nickel. For this purpose, GQDs are functionalized by various organic species including cysteamine, decanethiol, and mercaptopropionic acid (MPA) towards specific electrostatic interaction with metal ions of Fe (II), Cu (II), Co(II), Hg (II), Mn (II), and Ni (II). Therefore, an innovative GQDs-based miniaturized chemo-system was proposed for the environmental analysis. Additionally, the results were confirmed using fluorescence spectrometry as an optical detection method. Finally, this simple and efficient colorimetric platform was used for facile metal ions detection in human urine models, and environmental fluids, which can provide a commercial device for sensing contaminants by non-professional users in biomedical/environmental mixture. As an economical technique, this platform presents a "mix-and-sense" system without dye (as a side substance) or chemical treatments. The low instrumental requirements, the color uniformity, and the disposability of OD- μ PADs approve the commercial application of the engineered ion-chemosensor. [ABSTRACT FROM AUTHOR]

The reuse and recycling of waste paper sludge is increasing rapidly as far as the economical and positive environmental benefits are realised.In this study, primary sludge coming from a large production plant, located in the centre of Italy, was collected and the environmental quality of the sludge was assessed through geotechnical, physical and chemical analysis and leaching tests, as required by the Italian regulation on solid waste recovery. The results suggest that primary sludge from paper industry do not represent a major threat for the environment in regard to the heavy metal content. The use of this sludge for in situ applications appears an interesting avenue for an integrated management of waste from the paper industry. [Copyright &y& Elsevier]

This study reports the synthesis of functional graphene quantum dots (GQDs) through the thermal pyrolysis of D-penicillamine (DPA) and citric acid towards water treatment. For the first time, a novel type of highly fluorescent probe for selective Cu2+ detection among 26 types of metal ions which considerably enhance the fluorescence intensity of GQD. Furthermore, the recognition effects can be strengthen addition of amino acids owing to raise the electron density of the system and boos the accumulation profile of the sensing molecules. This simple fluorescent probe was applied for facile metal ions recognition in human urine samples, as well as environmental fluids. The proposed DPA-GQDs supported amino acids respond to Cu2+, Hg2+, and Fe3+, with high sensitivity. The intensity of the fluorescence histogram of this probe significantly diminished in exposure to metal ions such as, Cu(II), Hg(II), and Fe(III). Moreover, in our work, microfluidic paper-based (µPADs) was fabricated through a facile and a cost-effective method. Cu2+ can selectively be recognized by GQD-DPA on the paper-based sensors by naked-eye. The functionalized DPA-GQDs is an excellent alternative to previously reported fluorescent probes for sensing, bio-labeling, and other biological usages in aqueous solution. Its nitrogen and oxygen-rich groups can coordinate with Cu2+ and cause to an apparent fluorescence quenching by the non-radiative electron-transmission. The technique presented in this paper is economical and simple in design, and provides a "mix-and-sense" protocol with no need to chemical- or dye-modifications. Our proposed Cu2+ sensing probe exhibits linear response in the concentrations ranging from 0.001 ppm to 5 ppm, with a lower limit of quantitation (LLOQ) of 0.1 ppm in both environmental fluids, and human urine samples. The enhanced color uniformity, the low instrumental needs of the stamp, and disposability of μPADs enable the application of the suggested paper-based device for the commercial diagnostics biosensor.

The current study was designed to isolate and identify superior cellulose-degrading fungi from Egyptian soils reached with cellulosic compounds, then production of bioethanol from paper wastes using this isolate. Among 9 fungal isolates, one isolate was selected as the highest cellulases producer. This isolate was identified by morphological and genetic characteristics as Aspergillus niger MK543209. Basal mineral salt medium amended with 1% rice straw was the best medium for cellulose-degrading enzymes production under submerged fermentation (SmF). Additionally, bagasse at 30% and urea at 2% were the best carbon and nitrogen sources, respectively. In respect to the environmental conditions, the optimum temperature, pH and incubation period were 45 °C, 5.5 and 4 days, respectively. The optimized conditions were applied to produce reducing sugars from paper wastes, followed by production of bioethanol as a renewable energy. A 0.9 g/l/h of ethanol were produced as the best value. This study may be considered the initial point for production of renewable energy and protection of environment from wastes. [ABSTRACT FROM AUTHOR]

• Waste paper was established as new raw material for HPC with zero waste approach. • Optimization for HPC synthesis from waste paper has been done. • Synthesized HPC was characterized by NMR, HPLC, SEM, IR, and XRD. Chemical modification of waste paper offers a good prospective for environment protection through minimizing the waste density. The study develops a new opportunity for recycling of waste paper through hydroxypropyl cellulose (HPC) synthesis. Waste paper cellulose was hydroxypropylated by alkalization and etherification process. The hydroxypropylation reaction conditions were optimized for reactant concentrations, reaction time and temperature. Maximum DS (1.15) was achieved at 1.5 M/anhydro glucose unit (AGU) NaOH concentration, 40 °C alkalization temperature, 2.5 h alkalization time, 27.82 M/AGU propylene oxide concentration, 3.5 h reaction time for hydroxypropylation and 55 °C hydroxypropylation reaction temperature. HPC sample (DS max. = 1.15) was examined for rheological behaviour and characterized by using FTIR spectroscopy, 1H NMR spectroscopy, XRD, HPLC and SEM techniques. This environment friendly approach explored an alternative new route for waste paper recycling and substantiated waste paper as a promising feedstock for HPC synthesis. The study further forms a real stepping stone towards resource conservation and recycling. [ABSTRACT FROM AUTHOR]

The relation between access to energy and indicators of development is well established. It is directly related to most pressing social, economic, environmental, and security issues like poverty, jobs and income level, access to social services, population growth, industrial and agricultural production, food security, health, climate change and environmental quality which affect sustainable development. It is predicted that access to energy will become an acute problem in developing countries in the near future, mainly under the impact of population growth and the rising cost of fuels. This paper looks at how access to and use of energy are related to poverty. It also provides an overview of Pakistan''s energy sector, discusses levels of energy services available to people in Pakistan, and potential future energy resources available at local level and their benefits. The study concludes by addressing the growing energy challenges; it has become inevitable for Pakistan to diversify its energy resources through developing indigenous energy resources, especially the renewables.

Abstract: Environmental problems caused by recycling wasted paper at a board paper mill provide the material of this study. Two scenarios have been investigated: The first being the treatment of the end-of-pipe, and the second being the control and management of pollution problems through the application of in-plant control and pollution prevention measures. Comparison between the two alternatives, based on a cost-benefit analysis and compliance with National Environmental Laws was done. From this study it was apparent that the implementation of the pollution prevention measures such as the recovery of fiber, reduction of fresh water consumption, and optimization of white water usage proved to be very cost effective. All the implemented solutions have short payback periods and resulted in great savings compared with the treatment of the end-of-pipe. [Copyright &y& Elsevier]

An innovative thermal-sensitive ink has been developed and thoroughly tested on polyester fabric. Unlike conventional methods, this new ink eliminates the need for chemical pretreatment and post-printing washing of the fabric before or after printing. It utilizes high-temperature disperse dyes and a biodegradable carrier molecule called a triblock copolymer, specifically Poly(ε-caprolactone-lactic acid)-poly(ethylene glycol)-poly(ε-caprolactone-lactic acid) (PCLA-PEG-PCLA). This remarkable copolymer comprises dihydroxy polyethylene glycol (PEG), ε-caprolactone (CL), and L‐lactide (LA). Upon contact with a heated surface, such as a fiber or textile, the ink droplets swiftly transition rapidly, transforming into a gel-like state. This transition enhances the ink's viscosity, effectively preventing undesired spreading and resulting in precise edge definition on the fabric. To comprehensively evaluate the performance of polyester fabric printed with this innovative ink, a series of meticulous evaluations have been conducted. These evaluations encompass pH levels, particle size, surface tension, viscosity, ink droplet formation, as well as real-time photo-rheological and LF‐NMR analyses conducted on the surface of the polyester fabric. The newly developed inks demonstrate exceptional effectiveness and are highly suitable for digital printing applications across various materials. Furthermore, the implementation of this new ink can significantly reduce the reliance on chemicals and minimize wastewater production during the manufacturing process. [Display omitted] • A novel thermosensitive ink has been prepared by combining a triblock compolymers (PCLA- PEG- PCLA) with high-temperature disperse dyes. • This new printing technology significantly reduces the use of chemicals by eliminating the need for pretreatment. • Fabrics printed with thermosensitive ink demonstrate excellent printing accuracy and color fastness.

[Display omitted] • CysA@AuNPs supported amino acids was synthesized using hydrothermal protocol. • CysA@AuNPs supported was used for the identification of Hg(II) and Cu(II). • CysA@AuNPs have well activity for ion sensing in aqueous solution. In this study, an innovative methods was proposed for the synthesis of cysteamine@gold nanoparticle (CysA@AuNPs) using one step protocol. Also, application of CysA@AuNPs for the sensitive recognition of Hg (II) and Cu (II) in aqueous media was investigated using optical techniques. This research work explains the development of a lightweight stamp for manufacturing of a novel microfluidic paper-based analytical device (μ PADs), as a simple colorimetric sensor for selective recognition of Hg2+ and Cu2+ within the other metal ions (Fe(III), Mn(II), Zr(IV), Ba(II), Mg(II), Sr(II), As(III), B(III), Al(III), V(III), K(I), Na(I), Mo(II), Co(II), Zn(II), Sn(II), Se(IV), Cr(III), Bi(III)) in aqueous, and human biofluids.

The low instrumental needs of the stamp, and disposability of μ PADs enable the application of the suggested paper-based device for the commercial diagnostics biosensor. [ABSTRACT FROM AUTHOR]

Abstract: From the utilization point of view, it is notable that the total element concentrations in the precipitated calcium carbonate (PCC) waste were significantly lower than the maximal allowable heavy metal concentrations for fertilizers used in agriculture and in forestry, set on the basis of the EU and Finnish legislation. The easily soluble Ca concentration of 168.5gkg−1 (d.w.) in PCC waste was 105 times higher than the typical value of 1.6gkg−1 (d.w.) in the coarse mineral soil in Finland indicates that the PCC waste is a potential agent for soil remediation and for improving soil fertility if it is used as fertilizer. According to a five-stage sequential extraction procedure, the highest concentrations of most of the elements occurred either in HF+HNO3 +HCl or H2O2 +CH3COONH4 fraction. This means that the major part of the elements retained in the PCC waste are not easy to extract (leach) under conditions normally found in nature. This is beneficial since, if inorganic materials and by-products are utilized in earth construction, the content of harmful compounds must be low and the harmful components must be tightly bound to the matrix.

• Bureaucratic autonomy is the elephant in the institutions matter room. • The flip side of growth in Peru includes the close to 8,500 abandoned mine sites. • Pressures from above and below enable the creation of "paper institutions". • We found little of bureaucratic autonomy in Hualgayoc and Pasco. • The resource curse debate has much to gain from qualitative and mixed methods. Over the last three decades, drawn by international influence and local discontent, mineral-dependent Peru has progressed in the acquisition of environmental protection regulations and policies for its mining industry. However, for regulations and policy announcements to matter, in face of power asymmetries and economic dependence, there must be bureaucratic autonomy. The cases of Hualgayoc and Pasco, scenarios of long and distinct processes of environmental damage and contention regarding mining in the Peruvian Andes, show fairly limited progress in environmental protection. This study on institutional change begins at the 1990s domestic-neoliberalism-meets-global-environmentalism juncture. The triumphant policy ideology of liberal boosting of the economy structured newborn environmental functions of the state for its mining industry. We show that pressures from above —the greened international political economy— and below —grassroots activism and protest— are contextual conditions enabling formal institutional change: they compel a resource-dependent developing country to carry out institutional reform to protect the environment from extractive industries. However, accretion of formal rules does not bring on their own bureaucratic autonomy for environmental protection. [ABSTRACT FROM AUTHOR]

With the increasing concerns of food safety and environmental protection, it is desirable to develop reliable, effective, and portable sensors for detection of organophosphorus pesticides (OPs). Here, a cascade reaction system integrated with threaded 3D microfluidic paper analytical device (3D μPAD) was firstly developed for background-free and visual detection of OPs in agricultural samples. Butyrylcholinesterase (BChE) hydrolyzed acetylcholine into thiocholine (TCh), which reduced MnO 2 nanosheets into Mn2+. With addition of OPs, BChE activity was irreversibly inhibited, and the generation of TCh and the reduction of MnO 2 nanosheets were prevented. Then the remaining MnO 2 nanosheets oxidized o -phenylenediamine into 2,3-diaminophenazine with yellow-emission fluorescence, which quenched the fluorescence intensity of red-emission carbon dots (RCDs) via inner-filter effect. Based on above mechanism, a ratiometric fluorescent system was established for OPs detection. Threaded 3D μPAD consisted of 4 layers, which allowed to load and/or add reagents to trigger the cascade reaction system for OPs detection. The fluorescent images presented distinguishable color variations from red to yellow with dichlorvos concentrations ranging from 2.5 to 120 μg L−1, and the limit of detection was 1.0 μg L−1. In the practical samples testing, threaded 3D μPAD can eliminate background influence on fluorescent signal for OPs detection. Threaded 3D μPAD integrated with ratiometric sensing platform has merits of accuracy response, facile operation, and background-free detection, which supplies a new alternative approach for on-site pesticide detection.

Understanding the chemical risk to environment and human health is an important issue when a waste management strategy and a control risk system are analyzed and selected. This is even more important at the end-of-life (recycling, recovery and disposal) scenario for a chemical due to the uncertainty in respect of the most susceptible receptors (e.g. workers), pathways (e.g. groundwater), routes (e.g. inhalation) and hazard (e.g. cancer) associated to a chemical exposure. Hence, selecting a group of sustainability performance indicators for estimating the chemical risk when evaluating end-of-life scenarios is a crucial task. Therefore, this manuscript focuses on a critical analysis of the sustainability indicators taxonomy which are used to assess chemical risk to the environment and human health during end-of-life scenarios. The insights from performing an extensive literature search in the largest database of peer-reviewed literature provide that chemical intake, hazard quotient, hazard index, and carcinogenic risk have been the most commonly used for human health chemical risk. In addition, previous research has been less focused on environment chemical risk, with ecological risk index being the most widely used indicator thus for. The most employed human health chemical risk sustainability indicators are part of a methodology suggested by U.S. Environmental Protection Agency for chemical risk assessment.

In the recent Comment on our paper ‘Life cycle environmental impacts of UK shale gas’ ( Applied Energy 134 (2014) 506–518), Westaway et al. ( Applied Energy , available online 20th March 2015) allege that we exaggerated the potential impacts of shale gas extraction in the UK. They first take an issue with our inclusion of worst case scenarios despite our clear declaration in several places in the paper that this is indicative of what could happen within the confines of a very ill-defined and highly variable future reality. Secondly, Westaway et al. claim that key assumptions in the modelling reflect illegal practices that would not occur, when in fact this is an exaggeration of the legal situation and these practices are still viable. This rebuttal addresses some of the claims made by Westaway et al. while welcoming further open and impartial discourse in this area. [ABSTRACT FROM AUTHOR]

In the paper industry, adding fillers can replace plant fibers in pulp, which is beneficial to environmental protection and cost reduction. However, the large-scale use of inorganic fillers can interfere with interfiber bonding, thereby affecting the physical properties of paper. Due to the loss of fillers and paper fibers, the pollution of paper machine white water is aggravated. In order to improve the above situation, diatomite was used as the matrix and modified by Al(OH) 3 in-situ precipitation. In this study, modified diatomite was used as a papermaking filler. Paper properties, retention and the chemical oxygen demand in papermaking wastewater were also evaluated. The results show that, compared with the blank control, the modified diatomite filler could effectively improve the retention rate and reduce the pollution of paper machine white water while maintaining the physical strength of the paper. Among them, the fiber retention rate of pulp raw material could reach 98.05% and the chemical oxygen demand content of paper machine white water was 30.10 mg L−1. [Display omitted] • Modified diatomite filler for paper making was prepared by in-situ precipitation of Al(OH) 3 on the surface of diatomite. • The modified diatomite changed the electronegativity of the surface and could link with pulp fibers better. • Wastewater quality and paper properties added by the modified diatomite and CPAM were significantly increased.

• Global recycling trade is analyzed by network method and top1 network perspective. • The evolution of global recycling trade networks shows three distinct stages. • The top1 recycling import network obviously differs from export network. • Recycling policy of economies has a serious impact on recycling trade pattern. Recycling trade transfers recyclable resources and relevant environmental pressures on a global scale to solve resources limitation problem for some economies and alleviate urgent environment protection pressure for other countries/regions. Correspondingly, recycling trade relationships among economies are changing profoundly with the constant adjustment of economic and environmental policies. Based on complex network approach and top network analysis, this paper aims to comprehensively explore the structural features and their evolutionary patterns of global recycling trade networks from the macro, medium and micro levels by using global multi-region input-output data. The results are: At the macro level, the depth of global recycling import and export markets has strengthened continuously. The breadth of recycling exports showed a "pre-concentration, post-diversification" trend, and the import market breath demonstrated an opposite trend. At the medium level, the community structure of the global recycling export market increased rapidly in the early stage and became stable in the medium and late stages, while that of import market rapidly declined in the late stage, which means the import market was more sensitive to relevant policies and economic events. At the individual level, developed economics have been trying to transfer recycling products to developing economies, causing the former dominate global recycling export markets and the latter dominate the import markets. Recycling policies of economies, especially the developing economies have a serious impact on the global recycling trade pattern. Therefore, China's new announcement in 2018 for prohibiting import "foreign waste" will inevitably have a huge impact on the global recycling market. [ABSTRACT FROM AUTHOR]

Ports are essential and strategic nodes of international trade and economic activities. The integration of port resources helps enhance the optimal division of port functions to further promote economic development. This paper explores the evolutionary trends of port integration policy from 2011 to 2021 in China through a text-mining approach. We first used the Latent Dirichlet Allocation (LDA) topic analysis method to analyze the port integration policies and summarize the evolutionary trends of port policies. In addition, an association analysis was conducted to explore port integration policies' impacts by examining their relationships among the environmental protection, digitalization level, and port development scale. Our findings suggested that China's port integration policy has evolved from specific and simple to abstract and complicated at the managerial level. Port development has enriched from infrastructure construction to the ideology of economic development. Our findings show that China's port integration is gradually improving the port operation. The findings of the study contribute to the extant literature by analyzing the port integration policy evolution in China and can be referred to by other countries. • Text mining method was used to explore the port integration policy evolution. • Port integration policy evolved from specific and simple to abstract and complicated. • Port development enriched from basic infrastructure to the governance model. • The evolution of port integration policy was related to reducing carbon emissions in the port sector. • The evolution of port integration policy made the ports intelligent in association with digital technology such as big data and AI.

In today's era, science and technology have undergone tremendous development, and the research on big data technology has become more and more mature. Many areas of human life have begun to apply big data technology, and big data technology has indeed brought more convenience to human life. With innovation, human life has also become better because of the development of big data. With the increase of people's awareness of environmental protection and sustainable development, more and more scholars have begun to pay attention to the research of multi-channel closed-loop supply chain.

• A novel matrix-matched calibration method for PM 2.5 metals analysis is proposed. • The method relies on self-made solid filter paper standards and quantified by ETV-ICP-MS. • Greatly reduces sample preparation and shortens the analysis time. • The method has promising applications in targeting environment protection. The use of polytetrafluoroethylene (PTFE) filter paper immersed in reference solutions is proposed as a novel external calibration strategy for the quantification of trace elements in fine particulate matter (PM 2.5) by direct solid sampling–electrothermal vaporization–inductively coupled plasma-mass spectrometry (DSS-ETV-ICP-MS). This technique facilitated the simultaneous quantification of Mg, Mn, Cu, Zn, As, Sr, Cd, and Pb concentrations in PM 2.5 samples collected on the PTFE filter paper. The feasibility of using this calibration method for DSS-ETV-ICP-MS was evaluated by studying physical samples collected in Hangzhou, China, and an NIST standard reference material (SRM) 1648a. The obtained results were in agreement with effective elemental concentrations (D r <±10%), and exceptional reproducibility (RSDs less than 9%) and the linearity of the calibration curve (R2 > 0.997) under the limits of detection (LODs) at the µg L−1 level were achieved using elemental platinum as an internal standard. Therefore, this study suggests that using filter paper as the support in immersion standard solutions is a reliable method for calibration and PM 2.5 trace elements quantification by DSS-ETV-ICP-MS.

Abstract: The effects of endocrine disrupting chemicals (EDC) on molluscs in both marine and freshwater polluted environments are a continuing area of concern resulting in many field and laboratory studies. However, molluscs are commonly infected with trematode parasites which, in order to obtain sufficient nutrients for their own development, naturally disrupt the functioning of the endocrine system of the host. The physiological effects of parasitisation on the reproduction and immune response of molluscs are summarised, using a number of examples, and the implications for EDC studies are discussed.

• A distribution dynamics approach is employed to examine the converge of TFEE across Chinese PAA level cities. • The findings show a clear convergence in TFEE. • Convergence comes more from efficiency drops in high TFEE cities than from efficiency gains in low TFEE cities. • The environmental protection polices in key cities improved energy efficiency. • Large-sized cities show better performance in energy efficiency than small- and medium-sized cities. Improving energy efficiency is considered the most direct route to reducing carbon emissions on a massive scale. To examine the long-run trend of China's energy efficiency, this paper employs a distribution dynamics approach to analyze the convergence of total-factor energy efficiency (TFEE) across 286 Chinese cities between 2002 and 2014. The result suggests the existence of convergence, which comes more from the efficiency declines in the high TFEE cities rather than the efficiency gains in the low TFEE cities. Despite the fact that a few cities have performed well in energy efficiency, the majority of cities have converged to a low-efficiency point. Further analyses show that the inefficiency was attributed to inefficient energy use in small- and medium-sized cities. Our analysis provides strong scientific support for China's ongoing energy conservation and environmental protection policies. [ABSTRACT FROM AUTHOR]

In the context of significant environmental changes, the urgency of adopting green innovation has become increasingly apparent as a central mechanism for adjusting industrial structures in China. This transition serves not only as a crucial way to address pressing environmental challenges, but also as a fundamental strategy to improve the ecological efficiency of urban areas. Existing research mainly keeps a close eye on the unidirectional relationship between variables such as technological innovation and environmental protection. There is less relevant literature that has researched the cointegration relationship among green innovation, industrial structure, and eco-efficiency of cities. The essential role of green innovation and industrial structure in reaching a higher eco-efficiency of city are discussed in this research and the relationship among these three variables are analyzed by the evidence from cities in China from 2011 to 2019. The fact that the variables are cointegrated in the long run is evidenced by the results for the full sample. The sub-sample results report that in the eastern region, green innovation, industrial structure upgrading, and industrial structure rationalization could improve urban eco-efficiency. However, in Midwest regions where economic development is relatively backward, green innovation's effect on urban eco-efficiency is not in a significant positive way. The results obtained in this paper have implications for different cities in China to formulate corresponding policies on green innovation, industrial structure, and urban eco-efficiency.

Realizing environmental protection and employment stability when facing strict environmental regulations is an essential issue of concern for many developing countries, including China. Based on a dataset of Chinese listed companies and a dataset of Chinese individual labor-force surveys, this paper uses an estimation technique pairing propensity score matching with a difference-in-differences estimator to examine the impact of the new Environmental Protection Law (EPL) on the supply and demand of labor at the micro level and the reallocation effect of interindustry labor at the macro level. The results show that the new EPL generated employment losses at the micro level. The policy reduces firms' labor demand by lowering firms' output and total investment expenditures and, in the process, does not stimulate firms' innovative behavior. Moreover, implementing the new EPL reduces the wage income of workers, which in turn reduces the labor supply. Conversely, at the macro level, the new EPL promotes the transfer of labor from polluting to cleaner industries, realizes the reallocation of labor between industries, and thus promotes the transformation and upgrading of regional industrial structure.

• A review with over 300 references on the utilization of challenging ashes. • Metal and phosphorus recovery from different ashes was addressed. • The key beneficial properties of biomass and MSW ashes were identified. In line with the objectives of the circular economy, the conversion of waste streams to useful and valuable side streams is a central goal. Ash represents one of the main industrial side-products, and using ashes in other than the present landfilling applications is, therefore, a high priority. This paper reviews the properties and utilization of ashes of different biomass power plants and waste incinerations, with a focus on the past decade. Possibilities for ash utilization are of uttermost importance in terms of circular economy and disposal of landfills. However, considering its applicability, ash originating from the heat treatment of chemically complex fuels, such as biomass and waste poses several challenges such as high heavy metal content and the presence of toxic and/or corrosive species. Furthermore, the physical properties of the ash might limit its usability. Nevertheless, numerous studies addressing the utilization possibilities of challenging ash in various applications have been carried out over the past decade. This review, with over 300 references, surveys the field of research, focusing on the utilization of biomass and municipal solid waste (MSW) ashes. Also, metal and phosphorus recovery from different ashes is addressed. It can be concluded that the key beneficial properties of the ash types addressed in this review are based on their i) alkaline nature suitable for neutralization reactions, ii) high adsorption capabilities to be used in CO 2 capture and waste treatment, and iii) large surface area and appropriate chemical composition for the catalyst industry. Especially, ashes rich in Al 2 O 3 and SiO 2 have proven to be promising alternative catalysts in various industrial processes and as precursors for synthetic zeolites. [ABSTRACT FROM AUTHOR]

Climate change and the resulting extreme weather events bring significant economic losses and many unstable factors. It is an important means to actively seek environmental protection and climate governance countermeasures to meet severe challenges. As an environmental protection tool widely used by the Organization for Economic Cooperation and Development (OECD), environmental taxes are expected to play an important role in combating climate change and reducing extreme weather events. Based on public goods theory, collective cooperation theory, externality theory and double dividend theory of environmental taxes, this paper takes 36 OECD countries as research samples and empirically tests the role of environmental taxes in mitigating climate change process and reducing extreme weather events through the establishment of panel Auto-Regressive Distributed Lag (ARDL) model. The empirical results show that the environmental taxes on the whole is conducive to reducing the frequency of abnormal temperature weather and plays a positive role in reducing carbon dioxide emissions in OECD countries. Further research shows that environmental budget and environmental technologies play a positive role in the process of environmental taxes to delay climate change and reduce extreme weather events. In other words, we should attach importance to the investment of environmental protection funds and the research and development of environmental protection technology while carrying out environmental taxes. The robustness test shows that the main regression results of this paper have strong robustness. The research in this paper enriches theories and existing literature related to environmental taxes and climate change, and provides new research ideas and policy guidance for delaying the process of climate change and responding to extreme weather events.

CEO statements from CSR (corporate social responsibility) reports serve as an important channel to promote the positive image of a company. It is critical for CEOs to take a positive stance to address the company's strategy to stakeholders. This paper examines grammatical stance constructions that US and Chinese Global Fortune 500 companies employed for establishing a responsible image in CEO statements. Based on 50 US and 50 Chinese CEO statements, the present paper investigates how CEOs use attitudinal, epistemic, and modality stance constructions to introduce their strategies for social responsibility. The findings of the study show that US CEO statements use significantly more attitudinal and epistemic stance constructions than Chinese CEO statements, indicating an affective stance taken by US CEOs. In addition, Chinese CEOs employ stance strategies focusing more on the companies' competence of environmental protection and self-improvement that conforms to the government policy. By contrast, US CEOs tend to actively present CSR participation in a wider range of social benevolence activities. The present study thus contributes to the increasing scholarly attention to CSR as well as to the understanding of different institutional practice across cultures. The study also provides implications for teaching and learning business writing and communication. • Grammatical stances in CEO statements of CSR reports were studied. • Stances were found to help establish a positive image of companies. • US companies use more attitudinal and epistemic stance constructions to establish a caring image. • Chinese companies privilege a representation of their competence and conformity to government policy. • ESP practitioners may use CEO statements to instruct the use of grammatical stance.

• Numerical modeling of thermoacoustic devices can be classified into 1-D linear and 2-D/3-D non-linear models. • Linear thermoacoustic models lose their utility, in the high amplitude and high frequency regime. • CFD modeling has proven to be an effective tool in capturing the nonlinearities associated with standing wave thermoacoustic devices. • Flow dominance in a 2-D plane inside SWTADs has allowed the performance evaluation of these devices utilizing 2-D CFD models. • CFD modeling of standing wave thermoacoustic devices primarily focus on stack and the region around it. Global environmental concerns have brought the challenge of developing renewable energy technologies to cope up with the world energy needs. Thermoacoustic devices present themselves as a viable alternative to replace conventional refrigeration and power systems due to their minimal carbon footprint. These devices involve complex flow physics encompassing transient phenomenon and conversion of acoustic and thermal energies for their efficient performance. With the rapid advancement in computational capabilities, extensive numerical work is carried out to gain detailed understanding of the thermoacoustic devices. In this paper, a detailed review of the numerical modeling techniques that have been applied in the field of Standing Wave Thermoacoustic Devices (SWTAD) is carried out. At first, a brief review of analytical method is presented and the need for numerical modeling is highlighted. Numerical modeling techniques ranging from simplified linear to detailed Computational Fluid Dynamics (CFD) models are reviewed in detail. Model configurations, capabilities and tools developed and utilized so far in the research area are summarized. Challenges associated with SWTAD and applications modeled using CFD are discussed. The paper concludes with some useful recommendations regarding the numerical modeling of thermoacoustic devices. [ABSTRACT FROM AUTHOR]

Supersaturation of dissolved gas in water will cause fish to suffer from gas bubble diseases and even death. Therefore, it is imperative to illustrate the dissipation process of dissolved gas and then seek measures to remit the negative effects of dissolved gas supersaturation on fish. Generally, adding solid media (SM) to water has proven to be an effective and economical way to remove supersaturated dissolved gas from aquaculture water. While, the supersaturated dissolved gas dissipation framework in solid media containing water was still unclear. In this paper, combined with laboratory experiments and research available in the literature, the dissipation framework of dissolved gas was proposed along with the calculation of the liquid gas interfacial transfer mass, solid wall adsorption mass, porous media adsorption mass, and inner dissipation mass. The solid wall adsorption coefficient was found to follow a power function of the contact angle, and the porous adsorption coefficient logarithmically increased with the specific surface area. It was found that the inner dissipation coefficient exponentially increased with increasing total dissipation coefficient. Utilizing an approximation algorithm method, a model for the prediction of the dissipation coefficient was established. The research reported in this paper could contribute to enriching the research field of supersaturated dissolved dissipation and is significant for ecological and environmental protection.

The aim of this paper is to show the concise chemico-physical adsorbent performance of water purification systems utilizing geo- (e.g., allophane, clinoptilolite, and smectite) and bio-polymer materials (e.g., chitosan or cellulose nanocomposite materials) and to propose an optimal ground-water remediation technique. The performance of geo-materials is evaluated based on the individual sorption and immobilization capacities for various priority substances and pollutants (e.g., lead, zinc, cadmium, copper, arsenic, and others), their availability, and cost-efficient use. A systematic assessment of the sorption potential of geo-materials in comparison to other available sorbents used for the removal of harmful aqueous metal ions is made through a literature review. This paper introduces novel sustainable technologies based on natural and tailored silicate-polymerized substances (geo-materials and geopolymers), and highlights their applicability in the treatment of water and solid matter contaminated by heavy metal ions. The advantages of geo-materials and geopolymers over other commercially available sorbents used for heavy metal ion removal from solution are presented through a literature review. Benefits and current challenges of geo-materials and geopolymers applications in water processing technologies and in environmental remediation are discussed, with recognition of their performance, individual sorption and immobilization capacities, availability, and cost-efficient use. The applications described here comprise: (i) the removal of heavy metal ions from contaminated water using in-situ remediation strategies; (ii) heavy metal ion immobilization through co-precipitation with silicate binders in underground stabilization and waste solidification scenarios; and (iii) a proposal for a new geo-material/geopolymer-based solidification and stabilization technology for efficient, sustainable, and simultaneous treatment of soil/sediment and groundwater at environmental hotspots. Clay-substituted geopolymers, smectite, and zeolites are distinguished by their superb sorption and immobilization capacities for heavy metal ions, while biosorbents can play an important role in the removal of metals, metalloids (e.g., arsenic), and other contaminants. More research on individual removal mechanisms of heavy metals will provide new clues on the development of remediation strategies in advanced scientific and field applications, and on atomic-to-micron scale processes occurring at the solid–liquid interface. [Display omitted] • Comparative study of geo-materials/geo-polymers application in water treatment. • Green sorbents show a high efficiency to remove heavy metal ions from solution. • Smectites and zeolites are superb sorbents and have high immobilization capacities for dissolved heavy metals. • A proposal for a novel groundwater purification system is presented.

In today's world, as ecological challenges continue to rise, the importance of environmental monitoring and conservation cannot be overstated. These efforts play a vital role in countering the adverse impacts of human activities on our planet. The development of predictive models that can accurately predict the results of different conservation measures is essential for the success of these conservation efforts. This paper's objective is to create a Machine Learning (ML) model that predicts how environmental changes can unfold. This prediction helps in proactive monitoring and conservation planning, considering factors like deforestation, air pollution, sea level rise, temperature shifts, and forest preservation. The model relies on machine learning techniques, including AdaBoost, ETS, Prophet, SARIMA, LightGBM, and TL-BLSTM models, to analyze data, uncover trends, and inform decision-making. By offering a thorough assessment of the effects of conservation approaches, this model aids in shaping well-informed decisions regarding the distribution of resources. As a result, this process strengthens initiatives designed to protect biodiversity and the Earth's natural resources. Predicting changes in environmental variables is the main goal of this research, which will improve effective environmental management. In order to draw conclusions that are meaningful, this study compares several models for each of the four crucial factors. [ABSTRACT FROM AUTHOR]

The shortage of fossil energy and the aggravation of environmental pollution have led to stricter requirements for energy conservation and environmental protection of automobiles. The development of new energy vehicles still needs time and space. The internal combustion engine is still the power source that automobiles will need to rely on in the future. Lean combustion is one of the key research directions for efficient and clean combustion technology for gasoline engines. In this paper, the effects of high-energy ignition coupling hydrogen blending on the combustion stability of lean-burn gasoline engines were studied by means of multi-point high-energy ignition and gasoline/hydrogen double direct injection. Through the combination of gasoline and hydrogen injection timing, a suitable stratified mixture can be formed in the cylinder. Combined with high-energy ignition, the fire core can be formed smoothly, and the flame spreads rapidly. The introduction of hydrogen increases the concentration of H in the reaction system, enhances the activity of the reaction system, and accelerates the oxidation process of fuel molecules. Compared with a pure gasoline engine, hydrogen blending can expand the lean burn limit by 66.2% and increase ITE (Indicated Thermal Efficiency) by 6.5%. NO x emission increases first and then decreases with the increase in excess air ratio, but when λ > 1.6, NO x emission is much lower than that of the equivalence ratio condition. HC (Hydrocarbons), CO, and CO 2 emissions are also lower than the equivalent ratio conditions. • Multi-point high-energy ignition with three spark plugs. • Gasoline and hydrogen double direct injection to achieve lean combustion. • Effects on combustion and emission of lean burn gasoline engine.

• Financial barrier is an encumbrance for eco-investment for firms. • The linkage between environmental behavior and credit accessibility is driven by the ownership structure. • The paper also investigates the relationship between credit access and corporate environmental behavior according to the pollution intensity of firms. Firms play a major role in facilitating green growth in developing nations by promoting environmental protection investment to control pollution caused during the manufacturing process. The paper explores whether the financial vulnerability of firms curbs their investment towards environmental practices that eliminate the creation of wastes or pollutants and hence acts as a deterrent towards green economy. Using firm-level data for manufacturing firms from 2010 to 2019, it is confirmed that financial barrier is an encumbrance for eco-investment by firms. We also focus on the environmental behavior of firms classified according to their ownership structure observing that government-owned firms (GOFs) tend to rely less on their internal and debt capital to finance their environmental investment, whereas private-owned firms (POFs) rely mainly on their internal capital. However, internal financing methods have generally no significant impact on the eco-investment decision of foreign-owned firms (FOFs). [ABSTRACT FROM AUTHOR]

Nowadays, internet public participation has become a powerful tool to supervise the pollution activities of the enterprises. However, fewer studies have focused on the effect of internet public participation on environmental protection. Thus, this paper use network platform data (Sina Weibo and Baidu) from 2013 to 2018 to test whether internet public participation can help control environmental pollution emissions. Firstly, this paper selects the number of micro-blogs with the Chinese keywords "environmental protection", "haze", "water pollution", "air pollution" and their Baidu index to describe the level of internet public participation. Secondly, the effect of the internet public participation on four environmental pollutants including industrial sulfur dioxide, industrial soot, industrial wastewater and industrial solid waste are explored using the mediating effect model. In addition, we have examined the government's intermediary effect on environmental pollutants emission. The study found that the internet public participation can significantly (p ≤ 0.05) reduce the discharge of the industrial waste water. In addition, the mediating effect of government is significant (p ≤ 0.05) on pollutant emissions. From the view of regional difference, internet public participation has significantly reduced the discharge of the industrial sulfur dioxide (p ≤ 0.1), industrial waste water (p ≤ 0.05) and industrial solid waste (p ≤ 0.05) in the east. • The effect of internet public participation on environmental protection is explored. • Network platform data (Sina Weibo and Baidu) is explored. • The government's intermediary effect on environmental pollutants is explored.

Dust control is of great significance to industrial process safety and environmental protection. Wet dust reduction is the most commonly used dust control technology, and the physical and chemical properties of water are closely related to its dust reduction ability. In order to improve dust reduction efficiency, scholars have done much fruitful work in the physical and chemical modification of water. It is essential to summarize the progress of this research direction and shows what is lacking at present in recent years. This paper reviews the research progress on improving the performance of water for dust reduction by physical and chemical methods in the past ten years. The physical methods are mainly adopted to improve dust reduction performance in spray technologies, which include air atomization, ultrasonic atomization, magnetized water and water mist charging. And the chemical methods are mainly used to prepare dust suppression materials, which can be distinguished by single-phase dust suppressants and gas-liquid two-phase dust suppression foam. In this paper, we analyze the advantages as well as disadvantages of various methods and point out the unresolved issues. Furthermore, the development directions are proposed to provide meaningful guidance for wet dust reduction technologies. [Display omitted] [ABSTRACT FROM AUTHOR]

The objective of this paper is to explore how environmental protection expenditures (EPE) affect innovation and investigate the potential causal relationship between the two variables. The novelty and main contribution of our paper to the literature stems from the fact that we look at total environmental protection expenditures from both the public and private sectors, and distinguishing between corporations and households in the private sectors. We also consider both inputs and outputs of innovation and address potential endogeneity issues in this relationship, which are both lacking in the current literature. Using a panel of EU countries over the period 2006–2020, this study generally finds a positive impact of EPE on innovation after controlling for the effects of trade, credit, education and inflation on innovation, and using the System GMM estimator to treat endogeneity. Moreover, EPE from the government sector drives the bulk of this positive impact. The core results are robust to alternative measures of innovation, alternative estimation techniques that address endogeneity (i.e., the Lewbel 2SLS, Mundlak, and Hausman-Taylor estimators) and the moderation effects of Climate Change Performance (CCPI). This study also provides a useful guide to policy makers engaged in environmental planning. • We evaluate the impact of environmental protection expenditures (EPE) on innovation in mainly EU countries. • We use longitudinal dataset for the group of EU countries over the period 2006–2020. • We find a positive impact of EPE on innovation. • The results are robust for observable heterogeneity, alternative measures of innovation and estimation techniques. • This study provides a useful guide to policy makers engaged in environmental planning.

Previous research has paid little attention to the multiple meanings of the concept of forest restoration. To gain a more comprehensive view of forest restoration, this paper compares the US forest restoration debate of the 1940s and 1990s, in the disciplines of ecology and forestry. The paper focuses on historical approaches to pasts and futures, and on "sociotechnical imaginaries" providing societal legitimacy to restoration ventures. Historical scientific papers constitute the paper's empirical sources. The analysis shows that, among ecologists and foresters, forest restoration of the 1940s was oriented towards efficiency and challenges such as wood demands during World War II, whereas restoration of the 1990s was oriented towards conservation and environmental challenges. The approaches of the 1940s′ ecologists and foresters seem motivated by a sociotechnical imaginary connecting forest restoration to societal progress , whereas the approaches of their 1990s′ counterparts seem motivated by a sociotechnical imaginary connecting forest restoration to the task of mitigating society's impacts. Based on the conclusions, it is argued that future research on forest restoration would benefit from comparing the idealized pasts of both yield- and conservation-oriented conceptions of forest restoration. • Historically, US ecologists' and foresters' approach forest restoration similarly. • Historically, US aims of forest restoration have changed from yields to conservation. • Research on forest restoration benefits from comparing restorers' view on the past.

Drawing from Peck and Tickell's (2002) theory of roll-back and roll-out neoliberalism and Brenner et al.'s (2010) theory of variegated neoliberalism, this paper uses comparative historical analysis to understand how the state of Wisconsin suppressed its legacy of progressive environmentalism and embraced neoliberal policy over time. Specifically, this paper examines the rapid expansion of concentrated animal feeding operations (CAFOs) in Wisconsin's dairy industry since 1995. As these large CAFOs have grown in size, so have the social and environmental problems related to their use, including pollution of drinking water sources for rural communities. Based on analysis of newspaper articles between 1965-2010, I observed that that a turning point towards neoliberalism occurred with the demise of the Office of the Public Intervenor (OPI), a legally designated adversarial force unique to the state that was created in 1967 after a powerful coalition of environmental social movements defeated an attempt to merge the offices of development and environmental protection. Despite the continuous efforts of industry, the effort to weaken environmental regulations and institutions in Wisconsin failed not only in 1967, but in 1984 as well. However, by 1995, immediately after the passage of the North American Free Trade Agreement, the state switched their support from populist environmental social movements to industry. Through deregulation, elimination of the OPI, and the gradual dissolution of environmental social movements, the state of Wisconsin created the conditions that enabled CAFOs to expand without the "burden" of environmental regulation. Subsequently, through re-regulation, Wisconsinites lost access to legal remedies that could curb polluting practices of large CAFOs. This research is part of a larger project to understand the environmental impacts of regulatory failure in the Core as states in the Global North continue to adopt neoliberal environmental policy. • Industry in Wisconsin failed in their attempts to de/reregulate environmental regulationsuntil 1995. • Deregulation included termination of the Public Intervenor (OPI)- an environmental watchdog agency created in 1967. • De/reregulation led by the state encouraged the rapid growth of CAFOs despite the pollution they cause in rural communities.

Carbon dioxide (CO 2) emissions and climate change risk have become constraints on global economic sustainable development. Environmental regulation (ER) is a key method for achieving synergy in CO 2 and pollution reduction in China. This paper is the first study to explore the effects of ER on CO 2 emissions by exploiting the National Environmental Protection 11th Five-Year Plan (NEP11-FYP). The implementation of the NEP11-FYP significantly decreases CO 2 emissions by 19.73% in key environmental cities relative to other cities. Heterogeneity analyses suggest that this negative impact is larger in western cities and cities with more pressure to reduce CO 2 emissions. Scale effects, structural effects, and technical effects might be three potential influencing channels through which ER contributes to the CO 2 reduction effect. In addition, the results of the spatial externality of the NEP11-FYP demonstrate a positive spillover effect in neighboring cities within a distance of 300 km and a negative spillover effect in cities more than 500 km away. Our empirical findings provide policy implications for implementing low-carbon transition strategies and reducing CO 2 emissions. [ABSTRACT FROM AUTHOR]

This paper analyses the interrelation between technological innovation (TI) and air quality (AQ) using the bootstrap rolling-window subsample Granger test for China. We find that TI has a twofold impact on AQ. On the one hand, TI brings better AQ. This result proves the technique effect, indicating that TI can improve AQ by directly reducing air pollutants emissions and facilitating clean energy use. On the other hand, TI can make AQ worse when TI mainly focuses on utilising fossil fuels to expand production, which proves the scale effect. In turn, AQ can also influence TI ; the direction of the influence is dependent on the severity of air pollution and the government's response. This study provides important policy implications for coordinating innovation and environmental conservation to achieve sustainable development. [ABSTRACT FROM AUTHOR]

One of the challenges in the transition to a low-carbon economy is how to improve the energy and environmental performance of migrants. China has experienced rapid urbanization and a surge in domestic migration in recent years. People migrate within China are an indispensable integral part of sustainable development. Do migrants engage in environmental affairs to the same extent as the locals? Extant literatures have paid insufficient attention to this topic. This paper contributes to the understanding of differences in environmental participation among urban residents who hold varying types of household registration (namely, hukou) identity. Drawing on large-scale survey datasets and the technique of matching, the study finds that: (1) the environmental engagement of migrants is less active than those owning hukou , (2) migrants' duration of residence, household income, and the level of barriers to obtaining local hukou moderate the above relationship, and (3) the lack of social trust and sense of belonging that comes with the absence of hukou identity are channels constraining migrants' environmental involvement. This article contends that further reform of the hukou system might be necessary to incentivize migrants to take a more proactive role in environmental matters. [ABSTRACT FROM AUTHOR]

Market segmentation led by "beggar-thy-neighbor" and "local protectionism" among local governments is the deep institutional reason of environmental pollution. Therefore, eliminating market barriers and accelerating regional market integration are important way to achieve green development. This paper develops a theoretical model for analyzing the relationship between market integration and air quality by introducing inter-regional trade cost and game behavior. Based on the panel data of 101 prefecture-level and above cities in the Yangtze River Economic Belt of China, we verify the effect and its mechanism of market integration on air quality. The results show that regional market integration is conducive to improving urban air quality, which is still supported by the robustness test. In terms of regional differences, market integration has a greater effect on air quality in the downstream than in the upstream and midstream. Market integration improves air quality by strengthening scale effect, accelerating industrial structure upgrading and promoting technological progress. Moreover, Environmental regulation and environmental performance assessment facilitates strengthening the air quality improvement effect of market integration. We suggest that China should continually promote market integration in the Yangtze River Economic Belt, strengthen environmental regulation, and establish a reasonable performance evaluation system, so as to build a green development linkage mechanism between environmental protection and economic growth.

In the context of China's carbon peak and carbon neutrality goals (the "dual carbon" goals), balancing economic development, environmental protection, and low carbon is a high priority. Therefore, exploring the impact of digital finance on carbon dioxide (CO 2) emissions is crucial. In this paper, we select the panel data of 241 cities in China from 2011 to 2020 and use the double logarithm model after verifying model forms to explore the impact of digital finance on urban CO 2 emissions. The results show a significant negative correlation between the level of digital finance and the intensity of CO 2 emissions. Heterogeneity analysis results show that the eastern region exhibits the greatest inhibitory effect, while the western region exhibits the lowest. The three sub-dimensions of digital finance can all reduce carbon emissions, but the usage depth dimension has the greatest reduction effect, while the coverage breadth dimension is slightly lower. Through mediating effect tests from two dimensions, we find that digital finance can achieve CO 2 emission reduction by promoting scientific and technological innovation. These findings have implications for understanding the carbon reduction effectiveness of digital finance and achieving the dual carbon goals. [ABSTRACT FROM AUTHOR]
