We investigated MPs ingestion in four sympatric Cultrinae fish species from Dianshan Lake, China, using gastrointestinal tract and stable isotope analyses. MPs were widespread, but abundance was low (1.25 ± 2.36 items/ind.). Fibers dominated and consisted mainly of polyethylene terephthalate and polyester, likely derived from fishing gear and domestic laundry. Cultrichthys erythropterus showed the broadest trophic niche and highest MPs diversity, suggesting that opportunistic feeding increases exposure to diverse polymers. MPs abundance was not related to trophic position (Cultrichthys erythropterus: P = 0.24; Culter dabryi: P = 0.07; Culter mongolicus: P = 0.09; Culter alburnus: P = 0.77), providing no evidence of biomagnification among the examined Cultrinae species. However, MPs abundance was negatively correlated with condition index in three species, but not in Culter alburnus. These findings suggest that trophic niche width may be more closely associated with MPs exposure than trophic position within the examined fish assemblage.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149190519","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}

Cadmium (Cd) and arsenic (As) were the primary contaminants, consistently exceeding SQuiRT thresholds with enrichment levels reaching \"extremely severe\". Spatial analysis linked hotspots to urban/waste sectors, with a Cd-Sn association indicating localized sources. While the overall potential ecological risk was low, localized exceedances for Cd, As, and Ni indicate specific ecotoxicological threats. Human health risk assessments identified significant concerns for arsenic exposure via ingestion, particularly for children.

This study aimed to evaluate the effects of aqueous exposure to EM on somatic, biochemical, and genotoxic biomarkers in Oreochromis niloticus under controlled laboratory conditions. A 21-day subchronic bioassay was conducted using fish exposed to EM-contaminated water at nominal concentrations of 100, 500, 1000, and 2000 µg/L, alongside a control group. Genotoxic effects were evaluated using the comet assay and micronucleus test, while biochemical biomarkers - including acetylcholinesterase, catalase, glutathione S-transferase, and lipid peroxidation - were assessed to investigate oxidative stress and potential neurotoxicity. Somatic condition was also analyzed as an indicator of overall organism health. The results demonstrated genotoxic effects, evidenced by DNA damage. Biochemical analyses revealed alterations consistent with oxidative stress and potential neurotoxic responses, while somatic indices showed minor but detectable health changes. Although the observed damage levels were relatively low, these findings indicate that continuous exposure to EM and its byproducts can induce sublethal physiological disturbances with potential long-term consequences for aquatic organisms. Overall, this study highlights the relevance of ecotoxicological monitoring of EM in aquatic systems. The observed biological responses underscore its potential ecological risk, and future studies should incorporate preliminary stability assessments and evaluate long-term effects and degradation products to better understand the environmental impact of this antihypertensive drug.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13658400/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149163855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Glyphosate was applied at 1.5 and 2.25 kg a.i ha- 1, followed by sowing of urdbean at 7, 14 and 21 days after application. Residues of glyphosate and AMPA were quantified using a validated HPLC-FD method, which showed excellent linearity (R² > 0.99), recoveries of 84.96-95.80% for glyphosate and 84.15-96.32% for AMPA, with relative standard deviations (RSDs) ≤ 4.18% and a limit of quantification (LOQ) of 0.05 µg g⁻¹. Glyphosate persisted in soil up to 45 and 60 days at application rates of 1.5 and 2.25 kg a.i ha- 1, respectively, with corresponding half-lives of 11.40 and 16.09 days, while AMPA quantified up to 75 days. Glyphosate and AMPA residues were below the LOQ in all subsequently grown urdbean plant or grain samples. Glyphosate exhibited distinct and time-dependent responses towards soil microbial populations, with increased bacterial populations, transient stimulatory response of fungal and actinomycetes biomasses, and dynamic soil dehydrogenase activity that stabilized over time. These findings suggest that glyphosate applied at recommended dose for weed control permits safe sowing of urdbean at 7 days after application, without any adverse effect on succeeding crop or soil microbial population.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149147316","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}
