This study investigated the spatio-temporal distribution and ecological risks of microplastics in water and sediment of the downstream Ganges River of Bangladesh. Water and sediment samples were collected from nine sampling sites during pre-monsoon and post-monsoon seasons of 2024 and 2025. A total of 108 samples were analyzed using digestion, density separation, stereomicroscopic observation, and polymer identification. Microplastics were widely distributed in water (7.7 to 18.2 MPs/L) and sediment (1601 to 3813 MPs/kg) across the study area. FTIR analysis identified polyethylene (PE) (27%) and polypropylene (PP) (21%) as the dominant polymers. The ecological risk index (ERI) reached 709 (very high) for water and 1584 (danger level) for sediment. These findings suggest significant ecological risks and emphasize the need for improved plastic waste management and continuous monitoring.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149293830","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}

This affects the composition and properties of the water of the Tisza River, which, in turn, influence the state of the Danube River. Bioaccumulation of heavy metals (HM) and radionuclides (RN) by indigenous ichthyofauna can serve as an indicator of the ecological status of rivers. This study presents the identified patterns in the bioaccumulation of selected HM (Cd, Pb, Zn, and Cu) and natural gamma-active RN (the 238U and 232Th series) by a representative of the indigenous ichthyofauna, Squalius cephalus L., in the upper reaches of rivers of the Tisza basin. There is a general trend towards increasing HM content in Squalius cephalus L. samples along the riverbed across sections extending from mountainous to foothill landscape zones. This trend is associated with changes in the geology, tectonics and morphology of the river basin. An increase in the Zn/Cu ratio (from 10.6 to 19.2) in fish samples along the riverbed from mountainous to foothill landscapes was observed. The total specific activity of RN in Squalius cephalus L. samples ranges from 34.2 to 88.8 Bq⋅kg-1 and tends to decrease from mountainous to lowland landscapes. The ∑232Th/∑238U ratio ranges from 0.86 to 1.42. In mountainous landscapes, RNs in the 238U series make a significant contribution to the total specific radioactivity.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149260330","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}

Increased frequencies of morphological alterations ( average of 7.12 ± 0.71, and 7.24 ± 0.84 in DAENPs- and PAENPs- treated fish, respectively), nuclear alterations( average of 10.60 ± 1.97, and 11.99 ± 1.24 in DAENPs- and PAENPs- treated fish, respectively) and MNs (13.83 ± 0.16, and 11.83 ± 1.58 in DAENPs- and PAENPs- treated fish, respectively) were found. Similarly, compared with that in the control group, the level of malondialdehyde, a byproduct of lipid peroxidation was significantly greater, while the level of reduced glutathione was lower in the DAENPs- and PAENPs-exposed fish. The comet analysis parameters revealed that both DAENPs and PAENPs induced DNA damage. Annexin-V FITC/PI assay data demonstrate that DAENPs and PAENPs led to the induction of apoptosis. The present report suggests that morphological and nuclear alterations in the erythrocytes of experimental fish occur in response to genotoxic and oxidative stress induced by DAENPs and PAENPs. Furthermore, the observed apoptosis indicates DNA damage induced by the exhaust nanoparticles in fish erythrocytes.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149260338","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}

To assess heavy metal contamination, source characteristics, and associated health risks, water samples were collected from five sites over four seasons and analyzed for 11 metals. Mean concentrations followed the order Fe > Mn > Zn > Cu > Cr > Se > Pb > As > Ni > Hg > Cd, with all values below the limits specified by the Chinese Environmental Quality Standards for Surface Water (GB 3838 - 2002). Principal component analysis identified three major source components, reflecting mixed natural and anthropogenic influences. Health risk assessment indicated that drinking water ingestion was the dominant exposure pathway, with Cr contributing the largest share of carcinogenic risk although overall health risks remained within acceptable limits. The Newerow pollution index showed excellent water quality throughout the study period (PN < 0.7), with the highest values (0.37) observed at the LQ5 in winter. Despite the low overall pollution level, Hg exhibited comparatively pollution index values and warrants continued monitoring. These findings provide a scientific basis for water quality management and long-term environmental protection in this ecologically important drinking water source.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149260314","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}

Cd, Pb and As were the major contributors to non-carcinogenic risk, whereas the carcinogenic risk was mainly controlled by Cr and As. Higher levels of pollution, ecological risk and non-carcinogenic risk were found in the central, northeastern and northwestern areas, while higher carcinogenic risk was found in the northeastern and southern areas.

In addition, 1,987,646 wild boars (Sus scrofa) were harvested in 1990-2024. To better understand the the potential for exposure of wildlife to lead (Pb), we estimated the amount of Pb from spent Pb-core hunting bullets in gut piles available to wildlife scavengers. Calculations were based on the number of harvested animals, the proportion of gut piles left in situ, the proportion of hunters using Pb-based ammunition, the number of shots per animal and the amount of Pb in each gut pile. Over the 86-year study period, we estimated that a total of ~ 9,045 kg of Pb from spent hunting ammunition was deposited in gut piles left for scavenging. This amount of Pb, which translates to > 450 million lethal doses for eagles weighing ~ 5 kg (0.02 g of Pb per bird), is likely to have resulted in harmful exposure in a wide range of avian and mammalian scavengers feeding on the gut piles.

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.
