Abstract

In this study, elemental abundances of As, Cd, Cr, Co, Cu, Pb, and Zn in the 30 composite sediment samples from Jamuna River, Bangladesh were measured by atomic absorption spectrophotometer to assess their contamination level, toxicity, and ecological risks in both summer and winter season. In the summer season, mean concentrations of As, Cd, Cr, Co, Cu, Pb, and Zn in sediment samples were 2.82, 1.13, 25.30, 8.63, 22.01, 4.58, and 68.82 mg/kg, respectively. In the winter season, mean concentrations of As, Cd, Cr, Co, Cu, Pb, and Zn were 3.83, 1.48, 43.22, 13.86, 35.63, 8.48, and 100.27 mg/kg, respectively. The mean concentrations of all elements were found lower than the sediment quality guidelines values of probable effect level (PEL), effect range medium (ERM), and toxic effect thresholds (TET) in both seasons. There was a significant variation in elemental concentrations between wet and dry seasons and also between upstream and downstream sites (P < 0.05). Principal component analysis showed Zn, Cr, and Pb; As and Cu; and Cd and Co might have originated from the same geogenic source. The pollution evaluation indices showed consistent outcomes of almost no pollution for As, Cr, Co, Cu, Pb, and Zn, but moderately to strongly polluted for Cd in all seasons. The contamination level of elements follows the decreasing order of Cd > Zn > Cu > As > Co > Cr > Pb for both seasons. The elemental toxicity in the sediments follows the order of Cd > Cr > Zn > As > Cu > Pb, with a very high risk for Cd while a minimal risk for other elements. The ecological threats of the toxic elements were found moderate to very high. Therefore, the findings of our study concluded that the ecological condition of the Jamuna River posed a considerable risk for human health and living organisms. [ABSTRACT FROM AUTHOR]

Abstract

AbstractMicroplastics (MPs) possess a strong capacity to adsorb and biodegrade slowly, resulting in substantial harm to the environment and potential health risks. In recent years, a flourishing study of MPs has led to valuable advancements. This review article presents a comprehensive bibliometric analysis of global microplastic pollution, providing a deep understanding of published data, current progress, research trends, and focal points. We conducted extensive searches in the Scopus and Web of Science Core Collection databases from 2012 to 2021, utilizing the widely used R software for analysis. Our findings demonstrate a significant increase in micro(nano)plastic publications, with a growth rate of 73.0% from 2012 to 2021. China emerges as the predominant contributor in this field. The journal Science of the Total Environment has published the highest proportion of relevant articles (16.1%) and received the most citations (9801). The analysis further emphasizes polymer products and MPs as key research areas in the past decade. This study serves as a fundamental basis for future investigations into micro(nano)plastic pollution’s impacts on terrestrial and aquatic ecosystems. [ABSTRACT FROM AUTHOR]

Abstract

Environmental exposure to active pharmaceutical ingredients (APIs) can have negative effects on the health of ecosystems and humans. While numerous studies have monitored APIs in rivers, these employ different analytical methods, measure different APIs, and have ignored many of the countries of the world. This makes it difficult to quantify the scale of the problem from a global perspective. Furthermore, comparison of the existing data, generated for different studies/regions/continents, is challenging due to the vast differences between the analytical methodologies employed. Here, we present a global-scale study of API pollution in 258 of the world's rivers, representing the environmental influence of 471.4 million people across 137 geographic regions. Samples were obtained from 1,052 locations in 104 countries (representing all continents and 36 countries not previously studied for API contamination) and analyzed for 61 APIs. Highest cumulative API concentrations were observed in sub-Saharan Africa, south Asia, and South America. The most contaminated sites were in low- to middle-income countries and were associated with areas with poor wastewater and waste management infrastructure and pharmaceutical manufacturing. The most frequently detected APIs were carbamazepine, metformin, and caffeine (a compound also arising from lifestyle use), which were detected at over half of the sites monitored. Concentrations of at least one API at 25.7% of the sampling sites were greater than concentrations considered safe for aquatic organisms, or which are of concern in terms of selection for antimicrobial resistance. Therefore, pharmaceutical pollution poses a global threat to environmental and human health, as well as to delivery of the United Nations Sustainable Development Goals.

Abstract

This study demonstrates the development of effective modified films for As(III) removal from aqueous solution. Low-density polyethylene (LDPE) films were grafted by c (Sty/MAn) co-monomer using gamma irradiation. The grafted films were functionalized by six amine groups including semicarbazide, L-aspartic acid, 2-aminopyridine, thiosemicarbazide, hydroxylamine-HCl, and thiourea. The grafting was verified using FTIR that shows MAn carbonyl groups at 1860 and 1785 cm−1. The semicarbazide and L-aspartic acid functionalized films showed 100% and 75% removal efficiency, respectively, following the conditions of pH 7, 50 µg/mL As(III), 50 min contact time, and room temperature. The As(III) loaded chelating films treated with semicarbazide and L-aspartic acid were regenerated by contacting the films with 0.2 mol/L HCl solution for 90 min. The results show 100% release of the adsorbed As(III). The FTIR analysis of the regenerated films showed no change in the characteristic peaks, indicating the stability of film functionality in 0.2 mol/L HCl for 90 min. Additionally, the removal of As(III) using the regenerated films treated with semicarbazide or L-aspartic showed unaffected removal percentage up to eight adsorption-desorption regeneration cycles.

Abstract

Human activities around or within national highways, combined with atmospheric mixing, produce road dust, which can cause health problems through a variety of exposure routes. Thus, the study was aimed to investigate the contamination, spatial distribution, potential ecological and human health risks of various toxic heavy metals such as lead (Pb), copper (Cu), chromium (Cr), cadmium (Cd), zinc (Zn), nickel (Ni) and arsenic (As) in road dusts samples collected from traffic load and land-use types along the hectic Kushtia-Jhenaidah national highway, Bangladesh. The mean concentrations of Pb, Cu, Cr, Cd, Zn, Ni and As were found as 50.8 ± 15.7, 82.6 ± 17.2, 20.1 ± 5.7, 0.18 ± 0.06, 126.2 ± 40.7, 14.1 ± 4.7 and 0.12 ± 0.04 mg/kg, respectively, whereas Pb, Cu, Cd and Zn were evidently several times higher than the respective background values. The values of variance of coefficient (VC) exhibited that magnitudes of metal pollutions across the study sites were dominated by anthropogenic activities, while the principal component analysis (PCA) and cluster analysis (CA) identified vehicular and industrial emissions as the major sources of heavy metals in road dusts. The geo-accumulation index (Igeo) values indicated that most of the dust samples were unpolluted to moderately polluted by heavy metals. The contamination factor (CF) values were found in the following order: Cu > Pb > Zn > Cd > Ni > Cr > As, while the contamination degree (CD) values indicated moderate to considerable level of contamination. Furthermore, the study site posed low to moderate ecological risks, despite the fact that non-carcinogenic and carcinogenic threats from various pathways of exposure appear insignificant, with children being more vulnerable than adults.

Abstract

An effective toxicological assessment of soil-metal bioavailability and plant translocation processes is needed in view of the growing negative impact of trace element pollution on the terrestrial environment and human health. This study was conducted to assess the toxicological processes that regulate the plants' trace element absorption into their tissues, the suitability for human use, the potential sources of trace elements, and the risk to human health, using an integrated research methodology. Soils and sweet potato plants were collected from agricultural fields near the tannery waste disposal sites of Dhaka City, Bangladesh and inductively coupled plasma mass spectrometers (ICP-MS) were used to analyze the essential and toxic elements. The mean concentrations of total elements in soil followed the descending order of Fe > Zn > Mn > Cr > Ni > Pb > Cu > As > Cd and in plant Fe > Zn > Cu > Cr > Ni > Mn > Pb > As > Cd. In the edible tissues of sweet potato, the concentrations of essential and toxic elements exceeded the maximum permissible levels, indicating not safe for human consumption. The translocation factor (TF) revealed that studied elements are more accumulated in the leaves than tubers. The enrichment factor revealed minimal to very high enrichment of essential and toxic elements in the plant parts while the contamination factor showed low to very high contamination. Considering the health risk of toxic elements from plant samples, As and Pb caused non-cancer and cancer risk on human health. However, the present results suggested that regular monitoring of these essential and toxic elements in soil and plants as well as other food materials around the abandoned tannery waste disposal sites are necessary to prevent excessive build-up of these elements in the food chain.
