This study examines the bioaccumulation of these compounds and their impact on oxidative stress enzymes. Zebrafish embryos were used to assess the acute toxicity of TBT, TPT, and SnCl2. Toxicity tests were conducted on fertilized eggs using different concentrations of TBT, TPT, and SnCl2 (0, 1, 5, 10, 15, and 20 ng/L). The LC50, 96 h values for TBT, TPT, and SnCl2 in zebrafish embryos were 4.2, 8.7, and 12.56 ng/L, respectively. The study found an increase in the catalase (CAT) superoxide dismutase (SOD), and malondialdehyde (MDA) for TBT, TPT, and SnCl2. Moreover, TBT showed higher bioaccumulation than other compounds. The mortality rate was higher in embryos exposed to TBT, suggesting that embryos are more susceptible to TBT and can induce oxidative stress and disrupt the antioxidant equilibrium..","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"114 4","pages":"58"},"PeriodicalIF":2.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750552","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}

Despite growing concerns about their ecological and health risks, their distribution in African aquatic environments remains understudied. This study addresses the knowledge gap in PFAS contamination by analysing the spatial and temporal distribution of 18 PFAS in Apies River water and sediment in Pretoria, South Africa. 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. Upstream sediment had higher L_PFHpS (43.00 ng/g), L_PFDS (38.89 ng/g), and L_PFHxS (23.91 ng/g) than downstream (31.96, 27.84, and 18.02 ng/g, respectively).

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}
