Anurans are non-target organisms that are highly harmed by the effects of pesticides; however, studies investigating the effects caused by alternatives to pesticides in amphibians are scarce. Thus, this study aimed to evaluate the toxicity of nGER through behavioral analyses and muscle acetylcholinesterase (AChE) activity in Aquarana catesbeiana tadpoles exposed to different concentrations of nGER (1, 5, 10, and 20 mg L-1). Characterization of the nanoparticles in the aquarium water over the exposure time (96 h) revealed similar sizes among the different groups. However, the concentration of particles in the higher concentrations (10 and 20 mg L-1) decreased, indicating a process of aggregation and precipitation. The results of the biomarkers showed that these higher nGER concentrations induce lethargy in animals within 96 h of exposure. Though, induction of muscle AChE was only observed in animals exposed to 5 mg L-1. Thus, the neuro-depressive effect of nGER appears to be unrelated to AChE activity in bullfrog tadpoles. Therefore, the hypothesis of this study was partially accepted since higher concentrations of nGER significantly altered the behavior of A. catesbeiana. However, this was not related to changes in AChE. As this is the first investigation into nGER toxicity in amphibians, the findings emphasize the importance of evaluating non-target organisms before considering alternative pesticides as sustainable.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"114 4","pages":"60"},"PeriodicalIF":2.7,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143787673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conversely, the silver uptake in the intestine tissue on day 28 was 0.377 and 0.267 mg/g in the individual groups and 0.659 and 0.475 mg/g in the combined groups, respectively. Silver uptake in guppy tissues increased with higher concentrations and longer exposure times, and it varied depending on the specific tissues involved. Also, findings show that the depuration rate within 14 days for both tissues is similar across individual and mixture exposure modes, indicating a comparable capacity for the depuration of silver particles.

Surface water and sediment samples were collected upstream and downstream of the Apies River during dry seasons. The analysis of PFAS concentrations was conducted using liquid chromatography-tandem mass spectrometry. Statistical analysis, including paired t-tests, non-metric multidimensional scaling, and hierarchical cluster analysis, were applied to determine spatial and temporal trends. The study revealed significant spatial variations in PFAS contamination, with upstream locations consistently exhibiting higher concentrations than downstream. In surface water samples, L_PFBS, 4:2 FTS, 6:2 FTS, and L_PFHpS showed statistically significant differences (p < 0.05) between sites. Perfluorocarboxylic acids were the dominant PFAS class in surface water (50.47-57.15%), whereas perfluorosulfonic acids were more prevalent in sediments.

Despite this, the precise sources of atmospheric microplastics remain elusive. Our study focuses on elucidating the contribution of textile industries to atmospheric microplastic pollution by investigating the atmospheric fallout within and around textile industrial areas. Samples of suspended MPs were collected over seven days from indoor and outdoor locations in six textile industries at Dhaka city, Bangladesh. Through examination using fluorescent microscopy and Fourier transform infrared (FTIR) spectroscopy, we identified transparent and black microplastics, predominantly synthetic textile fibres with lengths ranging from 20 to 180 μm. Chemical analysis revealed polymers such as polyester, nylon, regenerated cellulose, and natural fibres among the observed microplastics. Deposition rates inside the textile factory ranged from 109.0 × 103 to 245.3 × 103 MPs/m2/day, while those outside ranged from 19.3 × 103 to 72.7 × 103 MPs/m2/day, indicating a significant contribution of textile operations to atmospheric microplastic contamination. Furthermore, we calculated the exposure of textile workers to microplastics through inhalation and ingestion, with average rates of 8.7 ± 4.3 mg/kg-Bw/year and 97.9 ± 17.5 mg/kg-Bw/year, respectively. These findings emphasize the substantial health risks faced by textile workers due to microplastic exposure. In conclusion, our study provides compelling evidence implicating the textile factory as a noteworthy source of atmospheric microplastic pollution. It is crucial to address this issue in order to reduce environmental contamination and protect the health of those employed in textile production plants.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"114 4","pages":"51"},"PeriodicalIF":2.7,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
