Abstract Over the last quarter century, increasing honey bee colony losses motivated standardized large-scale surveys of managed honey bees (Apis mellifera), particularly in Europe and the United States. Here we present the first large-scale standardized survey of colony losses of managed honey bees and stingless bees across Latin America. Overall, 1736 beekeepers and 165 meliponiculturists participated in the 2-year survey (2016–2017 and 2017–2018). On average, 30.4% of honey bee colonies and 39.6% of stingless bee colonies were lost per year across the region. Summer losses were higher than winter losses in stingless bees (30.9% and 22.2%, respectively) but not in honey bees (18.8% and 20.6%, respectively). Colony loss increased with operation size during the summer in both honey bees and stingless bees and decreased with operation size during the winter in stingless bees. Furthermore, losses differed significantly between countries and across years for both beekeepers and meliponiculturists. Overall, winter losses of honey bee colonies in Latin America (20.6%) position this region between Europe (12.5%) and the United States (40.4%). These results highlight the magnitude of bee colony losses occurring in the region and suggest difficulties in maintaining overall colony health and economic survival for beekeepers and meliponiculturists.

Accurate species identification is critical to monitoring programs because mis-identifications can lead to incorrect assessments of population status and trends. In the San Francisco Estuary, efforts to monitor the imperiled osmerid Delta Smelt (Hypomesus transpacificus) using morphology can be challenging because of the presence of the similar-looking non-native osmerid Wakasagi (Hypomesus nipponensis). In 2017, the US Fish and Wildlife Service’s field office in Lodi implemented a two-stage verification process for Wakasagi to help prevent Delta Smelt from being mis-identified as Wakasagi. Under this process, Wakasagi are initially identified in the field, independently identified a second time by an experienced staff member in the laboratory, then stored on-site where they can be made available for future studies. Using the recently developed Specific High-sensitivity Enzymatic Reporter un-LOCKing (SHERLOCK) assay for Wakasagi, we evaluated how well verification protocols performed by genetically identifying a subset of Wakasagi collected during routine sampling between 2017 and 2021. Through this study, we found that the protocols have served as an effective quality control measure for over 4 years and across multiple surveys. With the development of field-deployable genetics tools such as SHERLOCK, genetic identification will likely play an increasingly important role in ecological monitoring. We expect that hybrid approaches that combine morphological identifications by trained field crew with application of field-based genetic tools may offer an effective and efficient approach to ensuring data accuracy in the future.

Introduction: glaucoma is an essential international social and medical problem, as it leads to irreversible blindness in patients worldwide. Organization of treatment and prevention of complications using the most effective methods is the most important task of ophthalmologists at the present stage of the fight against glaucoma. The purpose of the study: to evaluate the management of assistance under the monitoring program «STOP! Glaucoma» to patients with suspected glaucoma, open-angle glaucoma, and more advanced stages of glaucoma. To compare the effectiveness of therapeutic and surgical methods of glaucoma treatment. Materials and methods: To detect and prevent the progression of glaucoma in patients, the LLC «VISIOBUD» Clinic developed and implemented the monitoring program «Stop! Glaucoma». The main task of program was to analyze the dynamics of glaucomatous changes in the optic nerve and, based on this, to determine whether glaucoma compensation is complete and whether the patient does not need a more radical treatment method to preserve visual functions. The following methods of empirical research were used: systematic approach - to determine the research elements between which there are relationships of objects and their properties; observation - to identify signs and external manifestations of facts; comparison – to determine similarities and differences and identify regularities; measurement; monitoring. Results: In the course of the study, the dynamics of changes in intraocular pressure in patients who follow the annual monitoring program «Stop! Glaucoma» in the clinic of LLC «VISIOBUD». 4 groups of patients (116 patients – 156 eyes) were under observation. Installed that in 75% of cases, patients need surgical treatment of glaucoma to preserve their visual functions. Surgical treatment of patients with open-angle glaucoma effectively preserves vision in 89% of cases. Conclusions: Timely detection, monitoring, and treatment of initial signs of open-angle glaucoma and symptoms of its progression affects the preservation and prolongation of visual functions in patients. In the long term, surgical treatment of glaucoma is more cost-effective, as the need to use expensive hypotensive drops is significantly reduced (by 2.5 times).

The St. Clair-Detroit River System (SCDRS) connects Lake Huron to Lake Erie and provides important habitats for many fishes of economic and ecological importance. Portions of the SCDRS are designated as Great Lakes Areas of Concern and fish production and conservation may be compromised. Efforts to address beneficial use impairments have focused on restoring habitat for native fishes and improving aquatic ecosystem health. Considerable site-specific research and long-term, annual fish surveys have examined responses to habitat improvements. However, there is uncertainty surrounding whether individual studies and surveys can assess (1) population-level benefits of habitat enhancements and (2) whether management objectives are being met. To identify monitoring gaps and inform long-term monitoring program development, we compared outputs from SCDRS fish monitoring surveys (based on discussions with regional agencies) with performance measures specified in management plans (obtained through gray literature searches). Performance measures for harvested species aligned well with outputs of existing surveys. In contrast, at-risk fishes often had objectives and performance measures that reflected knowledge gaps and study needs. Although harvested species were well-monitored relative to specified performance measures, at-risk fishes were less reliably collected by existing surveys, except for lake sturgeon Acipenser fulvescens. Effective evaluation of restoration efforts for at-risk fishes may require additional survey efforts that target species-specific habitat use and life history characteristics. [ABSTRACT FROM AUTHOR]

A relative lack of standardised long-term monitoring data often limits the ability of African conservancies to quantify their efficacy to protect wildlife. In this study, we combined eight 2-km long transects surveyed monthly between October 2017 and March 2020 (total 240 transects sampled) with a hierarchical multi-species and multi-season distance sampling modelling framework to: (1) estimate monthly density of an ensemble of 10 different large herbivores and (2) understand how species respond to changes in vegetation productivity and time across the Naboisho Conservancy in the Greater Mara Ecosystem, Kenya. We documented a total of 55,298 individuals from 6830 animal groups. The median coefficient of variation for all density estimates was 27.67%. On average, number of groups was higher at intermediate levels of vegetation productivity. We found that in general, populations of large herbivores remained stable in the conservancy during the study period, except for wildebeest which decreased in density. We showed that multi-species monitoring frameworks can be used to understand how species abundance changes across space and time, providing indications as to how they are responding to environmental dynamics or management prescriptions--both of which are valuable tools for under-resourced wildlife conservancies.

BackgroundThe well-being of individuals with chronic heart failure (HF) is significantly influenced by their health-related quality of life (HRQoL), which serves as a crucial measure indicating how HF affects their daily activities. Monitoring programs aimed at reducing the number of hospitalizations and improving functional conditions are currently being offered to patients with chronic HF.The objectiveTo examine the long-term health-related quality of life changes in patients with heart failure enrolled in a follow-up program after hospitalization and to evaluate the factors associated with quality of life of patients with heart failure.MethodsThis prospective study was conducted between 2019 and 2020 at the Department of Cardiology of Lithuanian University of Health Sciences. Patients were divided into two groups: Group I consisted of 71 patients (60.2%) where the Minnesota Living with Heart Failure Questionnaire (MLHFQ) score decreased by more than 10 points at 4th visit if compared to the 1st one; and Group II consisted of 47 patients (39.8%) where the MLHFQ score remained unchanged or increased by less than 10 points at the 4th visit if compared to the 1st visit.ResultsStatistically significant differences were observed between groups. In Group II, a history of myocardial infarction was more frequent (p = 0.038), and there was a significantly higher occurrence of significant coronary artery disease (p = 0.006). Laboratory parameters indicating liver function exhibited statistically significant deterioration among patients in Group II. Specifically, AST (p = 0.050), ALT (p = 0.010), and GGT (p = 0.031) levels significantly increased. Upon analyzing the echocardiographic data, a statistically significant difference was found between the groups in relation to the left ventricular ejection fraction (LVEF) (p = 0.043) and TAPSE (p = 0.031). An analysis of changes in dimensions related to QoL was conducted during the long-term follow-up program, which revealed statistically significant differences between groups in overall changes based on the MLHFQ (p

BackgroundThe aim of this study is to evaluate the current state of ototoxicity monitoring for patients receiving cisplatin chemotherapy in an academic medical center with particular attention to how closely monitoring adheres to national ototoxicity guidelines.MethodsCase series including retrospective medical records review of patients (age > 18) treated with cisplatin at University of California Davis Medical Center between January 2014 and August 2017. Patient and ototoxicity related variables were analyzed. Patients that underwent a transfer of care during treatment and with less than 3 months of follow-up were excluded.ResultsThree hundred seventy-nine patients met study criteria, of which 104 (27.4%) had a prior history of hearing loss. Prior to treatment, 196 (51.7%) patients were counseled regarding the ototoxic nature of cisplatin and 92 (24.3%) patients had a pretreatment audiogram. During treatment, 91 (24%) patients had documented otologic complaints. Only 17 patients (4.5%) patients had an audiogram ordered during their cisplatin treatment period. 130 (34.3%) patients had otologic complaints following cisplatin treatment. Audiograms were ordered for 20 (7.8%), 13 (5.1%), and 16 (6.2%) patients at 1-month, 3-month, and 6-month follow-ups, respectively. No patients in the study cohort received baseline, treatment, and post-treatment audiograms as recommended by national ototoxicity monitoring protocols. Patients with Head and Neck Cancer (HNC) represented the largest subgroup that received cisplatin (n = 122, 32.2%) and demonstrated higher rates of ototoxicity counseling (n = 103, 84.4%) and pretreatment audiograms (n = 70, 57.4%) compared to the non HNC group (n = 36, 36.2%, P

Mine workers are occupationally exposed to respirable dust, which can cause irreversible lung diseases and controlling exposure concentrations to as low as reasonably practicable is, therefore, essential. To implement exposure reduction strategies and adequately manage exposure to hazardous chemicals, exposure needs to be measured and recorded according to a standard exposure management plan. This study aimed to assess the available respirable dust exposure data measured between 2017 and 2022 in various work areas and job categories at two mining shafts and a concentrator plant of a Zambian copper mine. Additionally, the monitoring program implemented at the mine was assessed for appropriateness. Descriptive data analysis was used to create an exposure matrix comprising 253 exposure measurements. Approximately 5.6% of the measured concentrations exceeded the South African time-weighted average occupational exposure limit (TWA-OEL) of 3 mg/m3. The geometric means of respirable dust exposure for shaft A, shaft B and the concentrator plant were 0.44 mg/m3, 0.44 mg/m3, and 0.68 mg/m3, respectively. The work areas with the highest maximum exposure results were the tipping area (18.0 mg/m3) at shaft A, the sump and waste bin (8.05 mg/m3) at shaft B and the screening (10.8 mg/m3), secondary crusher (14.0 mg/m3), foreign ore bin (4.43 mg/m3), and tertiary crusher (5.07 mg/m3) areas at the concentrator plant. It was found that the monitoring strategy implemented at the mine was flawed and did not collect a sufficient number of samples in each area during each year to make rigorous statistical assessment possible. This study highlights the sampling strategy’s shortcomings and recommends adopting a standardized monitoring strategy, such as EN689, to improve the respirable dust monitoring program at the mine. Additionally, this strategy can be implemented across Zambia and, if implemented correctly, it has the potential to be improve exposure monitoring across the country as no standard sampling strategy is currently enforced by the Government.

A large proportion of endangered species lack good-quality data for assessing population trends. Obtaining these data is especially challenging in remote arid ecosystems, in part because these desert environments have historically attracted less scientific attention and funding than more mesic areas. The Sahara-Sahel biome in northern Africa is home to over 1000 species of terrestrial vertebrates, of which 79 have been classified as threatened or near-threatened by the IUCN Red List. This includes the Nubian bustard (Neotis nuba), a species with deficient ecological information and unknown population trends. In this study we used non-systematic data collected over a 10-year period (2008–2017) across the Termit and Tin-Toumma National Nature Reserve in Niger to i) study the temporal trend in the proportion of areas occupied, ii) map occurrence, and iii) assess how vegetation productivity, elevation, and surface roughness affect species occupancy. We implemented a single-species, multi-year site-occupancy model with an intrinsic conditional autoregressive structure to account for detection probability and the spatial autocorrelation nature of the non-systematic patrolling dataset. Our results showed that birds were imperfectly detected, and detection probability increased for longer transects. Occupancy probability was higher in higher elevated areas and in smoother terrain. Contrary to expected, occupancy probability decreased with increasing vegetation productivity. However, all parameters presented high uncertainty. We found a small positive trend in the proportion of areas occupied by Nubian bustards across the study area and mapped the spatial distribution after accounting for the spatial autocorrelation. Our study provides a better understanding of the population status of Nubian bustards across the ecosystem and will serve as a guide to target and improve surveys for future conservation efforts. Systematic data collection is always advisable for monitoring biodiversity. However, our analysis demonstrates that combining advanced modeling with observations from non-systematic patrolling activities in protected areas can be used for assessing population trends of other endangered and data-deficient species across remote areas.

Support within the nursing community for those coping with substance misuse has been lacking for over a hundred years. A review of the history of substance use disorders in nursing reveals that nurses still encounter similar risks, stigma, and punishments today. Kristin, a nurse for over 30 years, tells her story of trials, tribulations, and triumphs with substance use. She shares how having to face early recovery on her own sparked the development of the Wisconsin Peer Alliance for Nurses (WisPAN). WisPAN offers a community for nurses in recovery to provide peer support to those taking their first steps on the journey toward recovery. [ABSTRACT FROM AUTHOR]

MILK contamination , *AFLATOXINS , *RAW milk , *FOOD safety , *FEED contamination , *ENZYME-linked immunosorbent assay , *FUNGAL metabolites - Abstract
Aflatoxins (AFs) are fungal metabolites that are found in feed and food. When ruminants eat feed contaminated with aflatoxin B1 (AFB1), it is metabolised and aflatoxin M1 (AFM1) is excreted in the milk. Aflatoxins can result in hepatotoxic, carcinogenic, and immunosuppressive effects. The European Union thus set a low threshold limit (50 ng/L) for presence of AFM1 in milk. This was in view of its possible presence also in dairy products and that quantification of these toxins is mandatory for milk suppliers. In the present study, a total of 95,882 samples of whole raw milk, collected in northern Italy between 2013 and 2021, were evaluated for presence of AFM1 using an ELISA (enzyme-linked immunosorbent assay) method. The study also evaluated the relationship between feed materials collected from the same farms in the same area during the same period (2013–2021) and milk contamination. Only 667 milk samples out of 95,882 samples analysed (0.7%) showed AFM1 values higher than the EU threshold limit of 50 ng/L. A total of 390 samples (0.4%) showed values between 40 and 50 ng/L, thus requiring corrective action despite not surpassing the regulatory threshold. Combining feed contamination and milk contamination data, some feedingstuffs seem to be more effective in defying potential carryover of AFs from feed to milk. Combining the results, it can be concluded that a robust monitoring system that covers both feed, with a special focus on high risk/sentinel matrices, and milk is essential to guarantee high quality and safety standards of dairy products.

Background: The ubiquitous nature of molds, their ability to colonize diverse substrates, and the lack of effective control measures have contributed to the high incidences of molds and mycotoxin contamination in foods and feeds. These dangerous secondary metabolites enter the food chain in the field, during storage, or later. Material and Methods: A total of 40 livestock feed samples were randomly collected from ten farms in eastern Algeria. The ten types of analyzed feed were: wheat bran, dried bread, alfalfa, straw, oat hay, barley, date scraps, grass silage, corn silage, and concentrate. Results and Discussion: Results show that all the samples were contaminated with different species of fungi. A total of 248 fungal strains were isolated. In terms of frequency, the genus Aspergillus was the most frequent fungi recovered from 32 samples (80%) between all feeds studied, followed by the genus Penicillium recovered from 31 samples (77.5%). Conclusion: As a preventive measure, appropriate agricultural practices could provide unfavorable conditions for the development of fungi and toxinogenesis. However, the installation of a mycotoxins-monitoring program may be necessary to protect animals' and consumers' health. [ABSTRACT FROM AUTHOR]

The presence of pesticide residues in waterbed sediments poses a significant concern for aquatic ecosystems' health. This study examined pesticide contamination in sediments of 38 water bodies, embedded in agricultural-dominated regions, across eight European countries. Three indicators were targeted: occurrence, type, and concentrations of multiple pesticide residues in sediments. 196 pesticide residues (including degradation products) were tested in the sediment samples. The analytical results showed that only one sample was 'pesticide-free', three samples contained a single pesticide residue, and the remaining 34 samples contained mixtures of residues. Overall, 99 different residues were found in the sediments, with a maximum of 48 in a single sample. Twenty-seven out of the 99 detected residues were not approved for agricultural use at the time of sampling. The numbers of detected residues and pesticide levels varied among countries. AMPA, glyphosate and DDTs were the most common residues in sediment samples with frequencies of 76, 61, and 52%, respectively. The sediments from the Czech Republic had the highest pesticide concentrations, with total pesticide concentrations ranging between 600 and 1200 μg kg−1. The lowest total pesticide concentrations were found in Slovenia, Switzerland, Croatia, and Denmark, ranging between 80 and 120 μg kg−1. Sediments presented a mix of non-persistent and persistent compounds. Twelve of the detected pesticides are very persistent/stable in sediments, raising concerns about the long-term impacts of pesticides. Our study on the distribution of pesticide residues in European sediments provides valuable insights into the extent of pesticide contamination and possible risks of pesticides to water bodies' health. It also underlines the need for monitoring, research, and policy efforts to mitigate the impacts of pesticides, and to evaluate potential risks of re-use of dredged sediments. [Display omitted] • A total of 196 pesticide residues were analyzed in 38 sediment samples. • The sediment samples originated from 38 water bodies, from eight European countries. • 99 different pesticide residues were found in the sediments. • AMPA, glyphosate, and DDTs exhibited the highest levels and detection frequencies. • Sediments presented a mix of non-persistent and persistent compounds.

The Western Mediterranean coast is under the influence of anthropogenic pressures, including land use, increasing amounts of dangerous waste and habitat destruction. In 2021, the French RINBIO network (http://www.ifremer.fr/envlit/) originally dedicated to assess chemical contamination in the region, focused on biological effects produced by contaminants and the interaction with natural variability in mussels using an active caging strategy. Cell and tissue level biomarkers were applied for 17 sampling sites divided in three sub-regions categorized by different environmental conditions. Results provide critical information for ecosystem health assessment using mussels as sentinel species in the Western Mediterranean Sea. The influence of natural and confounding factors (trophic condition, reproductive cycle, caging strategy), on biological responses to mild chemical contamination, was discussed and discriminated for health status assessment. Results provide valuable data available as reference values for the assessment of biomarkers and histopathological alterations for large-scale active biomonitoring campaigns in the Western Mediterranean Sea. • Environmental factors proved critical to interpret effects of pollutants. • The adequacy of the active biomonitoring strategy was confirmed. • Valuable biological data for the geographical area are reported. • Biomarker data reported herein are potential reference values for future studies.

Toxic algae and their toxins represent an emerging public health issue, particularly due to global warming. The toxicological mechanisms of neurotoxic phycotoxins and their human health effects have been widely described (paralytic, neurological, amnesic, and ciguateric toxins). Food poisoning by bivalve shellfish (mussels, oysters…) can cause serious or even fatal neurological disorders, as bivalves accumulate toxins by feeding on harmful algae. However, retrospective study of human shellfish poisoning highlighted the difficulties in identifying cases related to neurotoxic phycotoxins by gathering clinical and biological diagnostic confirmations on the one hand, as well as environmental contaminations on the other. To improve the collection of shellfish poisoning data, the French Agency for Food, Environmental and Occupational Health and Safety (ANSES), French Poison Control Centers (PCCs), the French Research Institute for Exploitation of the Sea (Ifremer) and the French Defense Procurement Agency (DGA) have developed a prospective surveillance of neurotoxins from algal origin that combines monitoring of poisoning cases (clinical monitoring), of harmful algae and their toxins in shellfish production areas (environmental monitoring), as well as of toxins levels in seafood leftovers and in biological samples from poisoned subjects. This original clinical and environmental monitoring will allow us to have a more complete view of phycotoxin human exposures that are underreported, and to implement measures to protect consumers.

Aflatoxins (AFs) remain the main concern for the agricultural and dairy industries due to their effects on the performances and quality of livestock production. Aflatoxins are always unavoidable and should be monitored. The objective of this paper is to bring to light a significant volume of data on AF contamination in several animal feed ingredients in Northern Italy. The Regional Breeders Association of Lombardy has been conducting a survey program to monitor mycotoxin contamination in animal feeds, and in this paper, we present data relating to AFB1 contamination. In most cases (95%), the concentrations were low enough to ensure compliance with the European Union's (EU's) maximum admitted levels for animal feed ingredients. However, the data show a high variability in AF contamination between different matrices and, within the same matrix, a high variability year over year. High levels of AFs were detected in maize and cotton, especially in the central part of the second decade of this century, i.e., 2015–2018, which has shown a higher risk of AF contamination in feed materials in Northern Italy. Variability due to climate change and the international commodity market affect future prospects to predict the presence of AFs. Supplier monitoring and control and reduced buying of contaminated raw materials, as well as performing analyses of each batch, help reduce AF spread. [ABSTRACT FROM AUTHOR]

The Water Framework Directive (WFD) 2000/60/EC established a framework for community action in the field of water policy. This Directive requires the monitoring of surface watercourses' quality, which is undoubtedly influenced by the sediment composition. Their function can serve the living and transport purposes of numerous microorganisms and algae, but sediment may be a medium for transmitting dangerous toxic substances that are harmful to all living organisms in the environment as well. Many substances (including chemical substances, metals, and nutrients) can accumulate in sediment over time and be released in water or contaminate aquatic species, thus potentially negatively affecting the ecological or chemical status. Furthermore, flood events as well as human interventions can remobilise deposited sediment and thus result in the downstream and cross-border transport of sediment-associated contamination. The purpose of this investigation was to calculate the daily values of chemical elements in the transmission of suspended sediment and its accumulation in the suspended matter collected at some hydrological stations in the Danube River Basin during high flow events. The joint vision for the "Mura-Drava-Danube" area is to use the Transboundary Biosphere Reserve (TBR) concept to maintain a living river ecosystem for biodiversity and ecosystem services and to promote nature-friendly economic development for the local communities of this rural region. Therefore, this region requires a permanent sediment quality monitoring program. [ABSTRACT FROM AUTHOR]

Citizen science (CS) is now very popular in ecology. The number of scientific publications referencing CS has increased steadily over the past 15 years, with more than 1150 publications today. However, the multiplicity of research involved suggests that this number is highly underestimated. Based on this paradox, a literature review on CS shows that while its formalization in 2009 facilitated its referencing, about 70% of the publications are not referenced using CS as keyword. To understand this under-representation, an analysis of 149 publications related to the famous Christmas Bird Count program shows that this underestimation is not mainly related to the diversity of keywords used to describe CS, but rather to the fact that CS is mainly considered as a method (four publications out of five). The results also show that taking into account the whole text of a publication would represent a substantial improvement for the analysis of scientific databases, whatever the field of research.

To understand the state and trends in biodiversity beyond the scope of monitoring programs, biodiversity indicators must be comparable across inventories. Species richness (SR) is one of the most widely used biodiversity indicators. However, as SR increases with the size of the area sampled, inventories using different plot sizes are hardly comparable. This study aims at producing a methodological framework that enables SR comparisons across plot‐based inventories with differing plot sizes. We used National Forest Inventory (NFI) data from Norway, Slovakia, Spain, and Switzerland to build sample‐based rarefaction curves by randomly incrementally aggregating plots, representing the relationship between SR and sampled area. As aggregated plots can be far apart and subject to different environmental conditions, we estimated the amount of environmental heterogeneity (EH) introduced in the aggregation process. By correcting for this EH, we produced adjusted rarefaction curves mimicking the sampling of environmentally homogeneous forest stands, thus reducing the effect of plot size and enabling reliable SR comparisons between inventories. Models were built using the Conway–Maxell–Poisson distribution to account for the underdispersed SR data. Our method successfully corrected for the EH introduced during the aggregation process in all countries, with better performances in Norway and Switzerland. We further found that SR comparisons across countries based on the country‐specific NFI plot sizes are misleading, and that our approach offers an opportunity to harmonize pan‐European SR monitoring. Our method provides reliable and comparable SR estimates for inventories that use different plot sizes. Our approach can be applied to any plot‐based inventory and count data other than SR, thus allowing a more comprehensive assessment of biodiversity across various scales and ecosystems.

Abstract Biodiversity has undergone a major decline throughout recent decades, particularly in farmland. Agricultural practices are recognized to be an important pressure on farmland biodiversity, and pesticides are suspected to be one of the main causes of this decline in biodiversity. As part of the national plan for reduction of pesticides use (Ecophyto), the French ministry of agriculture launched the 500 ENI (nonintended effects) monitoring program in 2012 in order to assess the unintended effects of agricultural practices, including pesticide use, on biodiversity represented by several taxonomic groups of interest for farmers. This long‐term program monitors the biodiversity of nontargeted species (earthworms, plants, coleoptera, and birds), together with a wide range of annual data on agricultural practices (crop rotation, soil tillage, weed control, fertilizers, chemical treatments, etc.). Other parameters (e.g., landscape and climatic characteristics) are also integrated as covariates during the analyses. This monitoring program is expected to improve our understanding of the relative contribution of the different drivers of population and community trends. Here, we present the experience of setting up the 500 ENI network for this ambitious and highly complex monitoring program, as well as the type of data it collects. The issue of data quality control and some first results are discussed. With the aim of being useful to readers who would like to set up similar monitoring schemes, we also address some questions that have arisen following the first five years of the implementation phase of the program.

ENVIRONMENTAL impact analysis , *MARICULTURE , *FISH farming , *AGRICULTURAL wastes , *EUROPEAN seabass - Abstract
Simple Summary: The importance of aquaculture for providing animal proteins to a steeply increasing world population is growing. Despite the many benefits from this practice, there are also many constraints. Among them, the eutrophication of seawater and unsustainability are of the utmost importance. Integrated multitrophic aquaculture (IMTA), consisting of the co-farming of organisms of different trophic levels, was conceived to overcome these problems, and it is still developing to reach sustainable practices. In the Taranto seas (southern Italy, Mediterranean Sea), the first attempt of an IMTA plant with fish, mussels, polychaetes, sponges, and seaweeds started within the framework of the REMEDIA-LIFE project. This plant was arranged in a pre-existing fish farm where the European seabass Dicentrarchus labrax and the sea bream Sparus aurata are bred in net cages. Here, we report the results of the ex-ante evaluation of the trophic conditions of the seawater around the plant, which is useful for assessing the bioremediation effectiveness of the IMTA action after its implementation. The results of an ex-ante survey aiming to assess the impact of a fish farm in the Mar Grande of Taranto (southern Italy, Mediterranean Sea) on the surrounding environment are reported. There, the implementation of an innovative IMTA plant was planned, with the goals of environment bioremediation and commercially exploitable biomass production. Analyses were conducted in February and July 2018. Both seawater and sediments were sampled at the four corners of the fish farm to detect the existing biological and physico-chemical features. The investigation was performed to identify the best area of the farming plant for positioning the bioremediating system, but also to obtain a data baseline, to compare to the environmental status after the bioremediating action. Data were also analyzed by canonical analysis of principal coordinates (CAP). All the measurements, in particular, microbiology and macrobenthic community characterization using AZTI's Marine Biotic Index (AMBI) and the Multivariate-AMBI (M-AMBI) indices, suggest that the effect of fish farm waste was concentrated and limited to a small portion of the investigated area in relation to the direction of the main current. A site named A3, which was found to be the most impacted by the aquaculture activities, especially during the summer season, was chosen to place the bioremediation system. [ABSTRACT FROM AUTHOR]

The ventilation filters from ventilation system in the control area of nuclear power plant will be regularly replaced. In general, the metal frame of the waste filters would not be activated and were expected with a low radiation level, thereby it could be recycled or reused after a systematic clearance assessment. As a regulatory requirement in China, this kind of assessment play a vital role in the radioactive waste management, and a detailed scheme should be established based on long-terms of experience and the unit-specific characteristics. Focus on this, a clearance assessment scheme for the metal frames in nuclear power plants was established in this paper, which would present experience in the radioactive waste management for the nuclear power plant operator and the authorities.

Abstract The open-air Archaeological Museum in Biskupin (Poland) preserves and shows to the public a prehistoric settlement of Lusatian culture dating back to Early Iron Age (eighth century BC). The monitoring of the environment and dynamics of the wood degradation in the burial conditions at the site is fundamental for the in situ preservation of archaeological wooden materials. A monitoring program thus started in 2003 at the Biskupin site, using contemporary sound oak wood that was placed in two wet burial environments, characterised by different conditions. A multi-analytical protocol was exploited to obtain information on the structural, physical and chemical conditions of the buried wood. The study involved the application of gravimetric and wet chemical analysis, and instrumental techniques, including infrared spectroscopy (FTIR) and analytical pyrolysis (Py–GC/MS) to evaluate alterations in the buried oak wood over a 10-year period. The results showed that, during the burial period in both monitoring stations, there was only limited chemical transformation of the polysaccharide component, mostly involving hemicelluloses. The differences observed might be due to the natural compositional variability and inhomogeneity of oak wood. The final condition of the wood was very similar in the two burial environments. It is therefore suggested that the wet burial conditions in the Biskupin site represent a safe conservation environment for the in situ preservation of the wood remains, at least those presenting a good initial preservation state. This supports the conservation strategy adopted in the Biskupin Museum site.

aflatoxins ,AFM1 ,mycotoxins ,monitoring program ,Medicine - Abstract
Aflatoxins (AFs) are fungal metabolites that are found in feed and food. When ruminants eat feed contaminated with aflatoxin B1 (AFB1), it is metabolised and aflatoxin M1 (AFM1) is excreted in the milk. Aflatoxins can result in hepatotoxic, carcinogenic, and immunosuppressive effects. The European Union thus set a low threshold limit (50 ng/L) for presence of AFM1 in milk. This was in view of its possible presence also in dairy products and that quantification of these toxins is mandatory for milk suppliers. In the present study, a total of 95,882 samples of whole raw milk, collected in northern Italy between 2013 and 2021, were evaluated for presence of AFM1 using an ELISA (enzyme-linked immunosorbent assay) method. The study also evaluated the relationship between feed materials collected from the same farms in the same area during the same period (2013–2021) and milk contamination. Only 667 milk samples out of 95,882 samples analysed (0.7%) showed AFM1 values higher than the EU threshold limit of 50 ng/L. A total of 390 samples (0.4%) showed values between 40 and 50 ng/L, thus requiring corrective action despite not surpassing the regulatory threshold. Combining feed contamination and milk contamination data, some feedingstuffs seem to be more effective in defying potential carryover of AFs from feed to milk. Combining the results, it can be concluded that a robust monitoring system that covers both feed, with a special focus on high risk/sentinel matrices, and milk is essential to guarantee high quality and safety standards of dairy products.

In order to increase efficiency of activities aimed at reducing impacts exerted by leading health risk factors it is necessary to optimize observation over the existing social and hygienic situation within social and hygienic monitoring (SGM). It is also necessary to substantiate reference points where monitoring posts for controlling ambient air quality should be located within zones influenced by industrial enterprises, primarily those ranked as economic entities that could cause extremely high or high potential health risks. Methodical approaches to optimizing monitoring programs and location of monitoring posts within SGN system at the municipal level were implemented with complex analysis of health risk factors occurring due to economic activities by an enterprise that dealt with alumina production (Achinsk city in Krasnoyarsk region). The analysis included assessing and ranking potential threats to population health, first of all, to the respiratory organs; substances emitted into the atmosphere by the examined enterprise; consolidated calculations of ground concentrations diffusion; instrumental monitoring and field observations; hazard indexes under acute and chronic combined exposure to substances with one-way damaging impacts on the respiratory organs. The obtained results allowed creating a specific list of admixtures that should be observed systematically (particulate matter, PM2.5 and PM10, formaldehyde, manganese, copper, aluminum, nitrogen dioxide, sulfur dioxide, hydrofluoride, xylene, and toluene) and periodically (vanadium (V), nickel, and chromium (IV)). We substantiated two reference points where monitoring posts for controlling ambient air quality should be located within SGM system (instead of 5 existing mobile points) with specific fix-up on a territory; these points characterized a zone influenced by an alumina-producing enterprise. Control over ambient air quality at the chosen reference points within SGM does not require any interaction with an economic entity when surveillance and control activities are being performed; it is advisable to apply an extended program for monitoring over ambient air quality at these points and assess residual risks caused by exposure to substances that could be potentially hazardous for the respiratory organs as such risks can occur when an enterprise develops and implements activities aimed at achieving acceptable levels of risks.

Pesticides such as insecticides, fungicides, and herbicides can protect crops from insects, fungi, weeds, and other pests but must be applied following label instructions so that the pesticide residues in human and animal foods do not exceed maximum residue limits (MRLs, known in the US as pesticide tolerances). The US Food and Drug Administration (FDA) collects and tests foods for pesticide residues to enforce compliance with tolerances and publishes annual reports on pesticide testing results. In this study, results for over 56,000 human food samples collected and analysed under the FDA pesticide residue monitoring programme between fiscal years (FY) 2009 to 2017 were reviewed to identify trends not apparent in annual reports. The overwhelming majority of these samples, 98.0% of domestic and 90.9% of import human foods, were compliant with federal standards. Although herbicides may be more widely used, the 10 most frequently detected residues were insecticides and fungicides. On a yearly basis, the violation rate for imported samples is 3–5 times higher than the rate for domestic samples. The import violation rate increased over time, as did the number of residues detected. Targeted sampling of foods with higher commodity-specific violation rates appears to be a major contributor to the increased violation rate. Mismatches between US tolerances and international MRLs can lead to violations; this was especially marked for rice. Overall, the majority of violations are due to residues of pesticides not authorised for use in the US (lack of tolerances). While DDT continues to persist in the environment and was found in 2.2% of domestic samples and 0.6% of imported samples, 42.3% of DDT-positive samples were below the limit of quantitation. The trends and analyses identified in this paper may help FDA plan future sampling and continue to protect the food supply. [ABSTRACT FROM AUTHOR]

This paper presents six environmental noise indicators and two fuzzy acoustic indexes for urban spaces integrated with a permanent monitoring system. Likewise, they can help the management practices of land traffic and other noise generation sources in cities. The environmental noise indicators are defined by combining the equivalent continuous sound levels with A-weighting for time intervals of five, thirty, and sixty minutes and the non-harmful values set by national and international standards. Exposure and severity are the fuzzy indexes obtained with a model that weights the six environmental noise indicators utilising membership functions, rules and the centroid defuzzification method. The two fuzzy indexes are evaluation metrics of the social-urban acoustic impact that monitoring and evaluation programs can apply for standard time intervals or other time selection.Assessment traditional methods use the equivalent continuous sound level by integrating the sound pressure for a short or long time. When the analysis is for standard intervals, for example, from 7 to 19, 19 to 23 and 23 to 7 local time in hours, a sound pressure very high in short time subintervals greatly influences the equivalent continuous sound level of the long time interval. This situation is unfavourable for a quick assessment, and its interpretation may have significant uncertainty. The time intervals of five, thirty, and sixty minutes are very useful in environmental noise permanent monitoring systems. However, their traditional evaluations are complex to obtain the acoustic impact, the exposure time and noise severity that people receive during a prolonged stay or transit through an area. All tests used measurements from an environmental noise monitoring system over several months.

Noctuid pests, including tobacco budworm (Chloridea virescens (Fab.)) and bollworm (Helicoverpa zea (Boddie)), are significant pests of southern row crops including cotton (Gossypium hirsutum L.), corn (Zea mays L.), and soybean (Glycine max (L.) Moench.). This pest complex is seasonally monitored through Hartstack traps that are baited with synthetic lepidopteran pheromones across the southern United States. We examined bycatch from the noctuid traps deployed across the Mississippi Delta in 2015, 2016, and 2017 for the presence of bees. The most abundant species collected were honey bees (Apis mellifera L.), bumble bees (Bombus spp.), and long-horned bees (Melissodes spp.); these three genera accounted for 82.4% of specimens collected. We also evaluated the proportion of local- and landscape-level habitats on the abundance and richness of the bees caught as bycatch. The proportion of natural and semi-natural habitat affected the abundance and richness of bees collected at the landscape level, but not at more local scales. Additional research is needed to better understand these interactions between bycatch and landscape factors to minimize non-target collections. [ABSTRACT FROM AUTHOR]

Implement the necessary measures is necessary to limit the potential damages and risks resulting from oil and gas exploration activities to take the necessary precautions and arrangements to protect the land, air, waters and the groundwater basins from pollution and damage. The Environmental Impact Assessment (EIA) process is used to ensure that environmental and social sustainability considerations are included in decisions regarding the Projects considering the possible impacts associated with the proposed Centralized Waste Facility (CWF). The EIA was undertaken with consideration of the environmental standards and guidelines to determine the environmental impact assessment of Halfaya Oilfield; this facility is located in Missan Province in southern Iraq, south east of Amarah City. The Project has been assessed with respect to the applicable Federal or Client standard. Where appropriate, international standards have been considered alongside Federal and Client standards for reference. The EIA commenced on the 13th of October 2014 and is expected to last a total of 9 months. The classification of wastes is made using the EU European Waste Classification (EWC) codes; these codes describe whether the material is hazardous, non-hazardous, or inert.

Citizen science (CS) is now very popular in ecology. The number of scientific publications referencing CS has increased steadily over the past 15 years, with more than 1150 publications today. However, the multiplicity of research involved suggests that this number is highly underestimated. Based on this paradox, a literature review on CS shows that while its formalization in 2009 facilitated its referencing, about 70% of the publications are not referenced using CS as keyword. To understand this under-representation, an analysis of 149 publications related to the famous Christmas Bird Count program shows that this underestimation is not mainly related to the diversity of keywords used to describe CS, but rather to the fact that CS is mainly considered as a method (four publications out of five). The results also show that taking into account the whole text of a publication would represent a substantial improvement for the analysis of scientific databases, whatever the field of research.

The expectation analysis on taxonomic sufficiency of a community is a useful tool to optimize sampling effort for bioassessment of environmental/ecological quality status. To identify the taxonomic breadth for monitoring surveys based on periphytic ciliate communities at different layers in water columns, the taxonomic breadth was studied based on a 2-week baseline survey at four depths of 1, 2, 3.5 and 5 m in coastal waters of the Yellow Sea, northern China. Using glass slides with 17.5 cm2 for each, samples with five sample sizes (1, 2, 3, 5 and 10 slides) were collected at each depth after a 14-day exposure. The ciliates represented a clear variability in taxonomic composition/breadth from surface layer to deep in the water column. The taxonomic diversity/distinctness measures generally showed a weak increasing trend from the low sampling effort to high. Analysis on homogeneity in taxonomic breadth demonstrated that 10 slides (175 cm2) were required for collection of periphytic ciliates at depths 1–5 m, 3–5 slides (52.5–87.5 cm2) were sufficient to collect the ciliates at depths of 1–3.5 m. It is suggested that an optimal sample size should be determined in monitoring programs using periphytic ciliates according to water depths in marine ecosystems.

AGROBIODIVERSITY , *TILLAGE , *CROP rotation , *BIODIVERSITY monitoring , *WEED control , *AGRICULTURAL chemicals - Abstract
Biodiversity has undergone a major decline throughout recent decades, particularly in farmland. Agricultural practices are recognized to be an important pressure on farmland biodiversity, and pesticides are suspected to be one of the main causes of this decline in biodiversity. As part of the national plan for reduction of pesticides use (Ecophyto), the French ministry of agriculture launched the 500 ENI (nonintended effects) monitoring program in 2012 in order to assess the unintended effects of agricultural practices, including pesticide use, on biodiversity represented by several taxonomic groups of interest for farmers. This long‐term program monitors the biodiversity of nontargeted species (earthworms, plants, coleoptera, and birds), together with a wide range of annual data on agricultural practices (crop rotation, soil tillage, weed control, fertilizers, chemical treatments, etc.). Other parameters (e.g., landscape and climatic characteristics) are also integrated as covariates during the analyses. This monitoring program is expected to improve our understanding of the relative contribution of the different drivers of population and community trends. Here, we present the experience of setting up the 500 ENI network for this ambitious and highly complex monitoring program, as well as the type of data it collects. The issue of data quality control and some first results are discussed. With the aim of being useful to readers who would like to set up similar monitoring schemes, we also address some questions that have arisen following the first five years of the implementation phase of the program.

IODINE deficiency , *DELPHI method , *MEDICAL personnel , *MEDICAL scientists - Abstract
Background: Although substantial progress has been made in recent decades in eliminating iodine deficiency, iodine deficiency disorders (IDDs) are still prevalent in European countries. Challenges include ineffective public health programs and discontinuation of IDD prevention. However, the barriers against the implementation and continuation of prevention and monitoring of IDD remain unclear. Therefore, the objective of our study was to identify potential barriers against pan-European IDD prevention and monitoring programs and to find solutions for the different challenges. Methods: We conducted a Delphi study consisting of three rounds. We identified potential participants with expertise and experience in relevant fields from all European countries, including policy makers, health care professionals, health scientists, and patient representatives. The Delphi method was conducted with open-ended questions and item ranking to achieve group consensus on potential barriers against national and pan-European IDD prevention and monitoring programs and related solutions to overcome those barriers. The answers of the Delphi rounds were analyzed using qualitative content analysis and descriptive analysis methods. In addition, we conducted two expert interviews to analyze and discuss the study results. Results: Eighty experts from 36 countries and different fields of work participated in the first Delphi round, 52 in the second, and 46 in the third. Potential barriers include challenges in the fields of knowledge and information, implementation and management, communication and cooperation, political support, and differences between the European countries. Ranked solutions addressing these barriers include cooperation with different stakeholders, gaining knowledge, sharing information, the development of a European program with national specification, European guidelines/recommendations, and European monitoring. The ranking gives a first overview as to which of these barriers would need to be solved most urgently and which solutions may be most helpful. Conclusion: In our study, we derived key information and first insights with regard to barriers against IDD prevention programs from a broad range of stakeholders. Most barriers were found in the category of implementation and management. Also a lack of political support seems to play an important role. The findings of our study may help decision makers in health policy to develop more effective IDD prevention and monitoring strategies. [ABSTRACT FROM AUTHOR]

The results of an ex-ante survey aiming to assess the impact of a fish farm in the Mar Grande of Taranto (southern Italy, Mediterranean Sea) on the surrounding environment are reported. There, the implementation of an innovative IMTA plant was planned, with the goals of environment bioremediation and commercially exploitable biomass production. Analyses were conducted in February and July 2018. Both seawater and sediments were sampled at the four corners of the fish farm to detect the existing biological and physico-chemical features. The investigation was performed to identify the best area of the farming plant for positioning the bioremediating system, but also to obtain a data baseline, to compare to the environmental status after the bioremediating action. Data were also analyzed by canonical analysis of principal coordinates (CAP). All the measurements, in particular, microbiology and macrobenthic community characterization using AZTI’s Marine Biotic Index (AMBI) and the Multivariate-AMBI (M-AMBI) indices, suggest that the effect of fish farm waste was concentrated and limited to a small portion of the investigated area in relation to the direction of the main current. A site named A3, which was found to be the most impacted by the aquaculture activities, especially during the summer season, was chosen to place the bioremediation system.

- Abstract
Background: The well-being of individuals with chronic heart failure (HF) is significantly influenced by their health-related quality of life (HRQoL), which serves as a crucial measure indicating how HF affects their daily activities. Monitoring programs aimed at reducing the number of hospitalizations and improving functional conditions are currently being offered to patients with chronic HF., The Objective: To examine the long-term health-related quality of life changes in patients with heart failure enrolled in a follow-up program after hospitalization and to evaluate the factors associated with quality of life of patients with heart failure., Methods: This prospective study was conducted between 2019 and 2020 at the Department of Cardiology of Lithuanian University of Health Sciences. Patients were divided into two groups: Group I consisted of 71 patients (60.2%) where the Minnesota Living with Heart Failure Questionnaire (MLHFQ) score decreased by more than 10 points at 4th visit if compared to the 1st one; and Group II consisted of 47 patients (39.8%) where the MLHFQ score remained unchanged or increased by less than 10 points at the 4th visit if compared to the 1st visit., Results: Statistically significant differences were observed between groups. In Group II, a history of myocardial infarction was more frequent ( p = 0.038), and there was a significantly higher occurrence of significant coronary artery disease ( p = 0.006). Laboratory parameters indicating liver function exhibited statistically significant deterioration among patients in Group II. Specifically, AST ( p = 0.050), ALT ( p = 0.010), and GGT ( p = 0.031) levels significantly increased. Upon analyzing the echocardiographic data, a statistically significant difference was found between the groups in relation to the left ventricular ejection fraction (LVEF) ( p = 0.043) and TAPSE ( p = 0.031). An analysis of changes in dimensions related to QoL was conducted during the long-term follow-up program, which revealed statistically significant differences between groups in overall changes based on the MLHFQ ( p < 0.001). This difference was also observed across all dimensions, including the emotional, physical, and social aspects ( p < 0.001)., Conclusion: Patients who had a higher LVEF at baseline, as well as those with an etiology of ischemic heart disease (IHD), better liver function, and fewer manifestations of edema, demonstrated a statistically significant improvement in their quality of life throughout the course of the patient monitoring program., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Paleckiene, Zaliaduonyte, Dambrauskiene and Macijauskiene.)

The article analyses the spatial and temporal variation in the lower Danube sector of the physico-chemical quality indicators, selected to reflect the general characteristics and the effect / impact of the main pressures identified at basin level for the period 1996-2015, in 6 monitoring sections (from Baziaș to Reni). Based on the minimum, average and maximum multi-year values for all physic-chemical determinants that reflect the degree of variability of the values of the concentrations monitored for the analysed periods, they were interpreted in particular from the perspective of the interdependence between these parameters, their behaviour, the aquatic transformations /reactions, as well as from the point of view of correlation with the contribution of tributaries and sources of pollution. Longitudinal (upstream / downstream) variations have also been established over the 20-year period, concluding that most determinants / pollutants have an increasing spatial trend. From a temporal point of view, all determinants analysed from the point of view of the water quality improvement trends were determined, namely the temporal trends (especially in the Reni section) and the possible causes of variation were identified.

The open-air Archaeological Museum in Biskupin (Poland) preserves and shows to the public a prehistoric settlement of Lusatian culture dating back to Early Iron Age (eighth century BC). The monitoring of the environment and dynamics of the wood degradation in the burial conditions at the site is fundamental for the in situ preservation of archaeological wooden materials. A monitoring program thus started in 2003 at the Biskupin site, using contemporary sound oak wood that was placed in two wet burial environments, characterised by different conditions. A multi-analytical protocol was exploited to obtain information on the structural, physical and chemical conditions of the buried wood. The study involved the application of gravimetric and wet chemical analysis, and instrumental techniques, including infrared spectroscopy (FTIR) and analytical pyrolysis (Py–GC/MS) to evaluate alterations in the buried oak wood over a 10-year period. The results showed that, during the burial period in both monitoring stations, there was only limited chemical transformation of the polysaccharide component, mostly involving hemicelluloses. The differences observed might be due to the natural compositional variability and inhomogeneity of oak wood. The final condition of the wood was very similar in the two burial environments. It is therefore suggested that the wet burial conditions in the Biskupin site represent a safe conservation environment for the in situ preservation of the wood remains, at least those presenting a good initial preservation state. This supports the conservation strategy adopted in the Biskupin Museum site. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: The phytosteroid ecdysterone was recently reported to enhance performance in sports and may thus be considered as a substance of relevance in anti-doping control. To trace back an administration of ecdysterone from urine samples, analytical properties have been investigated to assess its integration into initial testing procedures (ITP) in doping control laboratories. Methods: Analytical properties of ecdysterone were evaluated using gas chromatography-quadrupole/time-of-flight-mass spectrometry (GC–QTOF–MS) and liquid chromatography (LC)–QTOF–MS. Its metabolism and elimination in human were studied using urines collected after administration. Results: The detectability of ecdysterone by GC–MS (after derivatization) and/or LC–MS(/MS) has been demonstrated and sample preparation methods were evaluated. Dilute-and-inject for LC–MS(/MS) or solid phase extraction using Oasis HLB for GC–MS or LC–MS were found most suitable, while liquid–liquid extraction was hampered by the high polarity of ecdysteroids. Most abundantly, ecdysterone was detected in the post administration urines as parent compound besides the metabolite desoxy-ecdysterone. Additionally, desoxy-poststerone was tentatively assigned as minor metabolite, however, further investigations are needed. Conclusion: An administration of ecdysterone can be targeted using existing procedures of anti-doping laboratories. Ecdysterone and desoxy-ecdysterone appeared as suitable candidates for integration in ITP. Using dilute-and-inject a detection of the parent compound was possible for more than 2 days after the administration of a single dose of ~ 50 mg. [ABSTRACT FROM AUTHOR]

- Abstract
oxic algae and their toxins represent an emerging public health issue, particularly due to global warming. The toxicological mechanisms of neurotoxic phycotoxins and their human health effects have been widely described (paralytic, neurological, amnesic, and ciguateric toxins). Food poisoning by bivalve shellfish (mussels, oysters...) can cause serious or even fatal neurological disorders, due to the accumulation in their flesh of natural toxins that develop in the water that surrounds them. However, retrospective study of human shellfish poisoning highlighted the difficulties in identifying cases related to neurotoxic phycotoxins by gathering clinical and biological diagnostic confirmations on the one hand, as well as environmental contaminations on the other. To improve the collection of shellfish poisoning data, the French Agency for Food, Environmental and Occupational Health and Safety (ANSES), French Poison Control Centers (PCCs), the French Research Institute for Exploitation of the Sea (Ifremer) and the French Defense Procurement Agency (DGA)have developed a prospective surveillance of neurotoxins from algal origin that combines monitoring of poisoning cases (clinical monitoring), of harmful algae and their toxins in shellfish production areas (environmental monitoring), as well as of toxins levels in seafood leftovers and in biological samples from poisoned subjects. This original clinical and environmental monitoring will allow us to have a more complete view of phycotoxin human exposures that are underreported, and to implement measures to protect consumers.
