This study assessed the relationship between total mercury (THg) levels in Holothuria polii and Holothuria tubulosa from two Southern Italian coastal sites differing for ecological and anthropogenic characteristics, and those in corresponding marine sediments. THg levels in holothurians were consistently low across species and sites (0.0022-0.0146 mg kg- 1 wet mass) and showed no direct correspondence with sediment levels, which were high (1.5080 ± 1.1687 mg kg- 1 dry mass) at the Ionian site (IS), and low (0.0055 ± 0.0028 mg kg- 1 dry mass) at the Adriatic site (AS). Despite lower sediment mercury contamination, the bioconcentration factor, indicator of the efficiency of metal bioaccumulation was higher at the AS site (3.54-4.76) than at the IS site (0.021-0.022), suggesting different mercury bioavailability in the sites. Size-related analyses of THg in holothurians indicated that THg levels in individual holothurians correlated positively with body size (p < 0.05), except for H. tubulosa from AS. Results demonstrate that site-specific factors, more than species-specific ones, play a key function in controlling mercury bioavailability and uptake in the studied holothurians, supporting their potential role in environmental monitoring and their safe consumption in the studied areas.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 3","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13524999/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148849658","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}

We predicted that neonicotinoid levels would be highest at the start of the season, coincident with planting, then taper off throughout the growing season. Our results revealed that 25 of 50 sites surveyed had concentrations of at least one neonicotinoid (imidacloprid or clothianidin) over United States Environmental Protection Agency (EPA) benchmarks for chronic exposure. Imidacloprid had high detection above EPA benchmarks in Cook County while clothianidin was more often above benchmarks in central Illinois. There was a negative relationship between clothianidin levels and ratio of agriculture on measured insect biomass at sites with a higher proportion of agriculture. We did not identify a clear peak of imidacloprid or clothianidin concentrations. This study suggests the high level of contamination found at protected sites is concerning for ecosystem health as insects are the target prey for many wildlife species.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 3","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13493470/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148786766","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}

In this study, the gastrointestinal tracts of commercially important finfish species along with a crustacean species, were analyzed to assess microplastic contamination and its potential entry into the food chain. A total of 540 samples (30 individuals from six species per season) were collected from the fishing harbour Kalamukku along the Keralam coast, India, across the pre-monsoon, monsoon and post monsoon season of 2021. Overall, microplastic ingestion was confirmed in 44.25% of the examined samples. Across the year, the prevalence of microplastics in the gastrointestinal tracts followed the order: Rastrelliger kanagurta (56.67%) > Mugil cephalus (50%) > Sardinella longiceps (45.56%) > Nemipterus japonicus (43.33%) > Thryssa malabarica (42.22%) > Fenneropenaeus indicus (27.78%). Season wise analysis revealed the highest prevalence during the post monsoon season (55.56%). The dominance of microplastics in the 300-500 µm size range (37.65%) indicates their greater susceptibility to ingestion by the analyzed species. Four colour types were recorded, with blue being predominant. Urban run-off and harbour related activities likely contribute to microplastic contamination in the study area. Selected microplastics, characterized by stereomicroscopy and Fourier-Transform Infra Red-spectroscopy, were dominated by polyethylene, polyurethane, and polypropylene. Thus, microplastics in edible species may represent a potential pathway into the human food chain, emphasizing the need for effective plastic waste management.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 3","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148786825","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 study collected raw sewage sludge from various urban sources in the state of Kerala, India, to evaluate its resource potential and assess ecological risks, with a focus on preliminary chemical characterization and risk screening. The average nutrient composition of the sludge samples revealed Total Organic Carbon (TOC) of 43.7%, Total Nitrogen (TN) of 4.86%, Total Phosphorus (TP) of 1.88%, and Total Potassium (TK) of 0.345%, with a Carbon-to-Nitrogen (C/N) ratio of 9.1. These values indicate agronomic potential of sewage sludge after appropriate stabilization method. However, ecological risk screening using pollution assessment indices indicate potential environmental risks upon land application. Hg exceeded the FCO (2009) limit in all sources, a nine-fold increase is reported in source SC4 and SC5. Cu exceeded the limit in source SC2 and SC5. Among the heavy metals assessed, Cd and Hg pose major ecological concerns based on the contamination and risk indices. Although, the sludge samples exhibited similar organic characteristics across different urban sources, metal contamination levels and associated risk indices varied significantly, reflecting source dependent inputs. These results indicate that sewage sludge reuse should be considered only after appropriate stabilization techniques, followed by continuous monitoring and site specific risk assessment before land application. The study also highlights the need to update regulatory frameworks to facilitate the safe, controlled and economically viable sewage sludge reuse, in line with the principles of a circular economy.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 3","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148786777","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 study integrates catchment morphometric analysis with water-column MP sampling across eight first-order streams in the Ona River Basin, southwestern Nigeria. MP concentrations exhibited pronounced spatial heterogeneity (13.58-63.58 items L⁻¹), with consistently higher values in streams draining densely populated and commercially active areas. Simple and multiple regression analyses revealed weak and statistically non-significant relationships between MP concentrations and classical morphometric indices, including stream length, form factor, circularity ratio, and elongation ratio, although the latter showed a marginal inverse trend. Diagnostic evaluation confirmed limited predictive capacity of morphometric parameters. These exploratory results (120 data points across 8 streams) suggest localized anthropogenic inputs are more closely associated with MP distribution than basin-scale geomorphic form, though anthropogenic and connectivity variables were assessed qualitatively rather than measured directly. The findings highlight the limits of applying traditional morphometric frameworks to synthetic pollutants in urban tropical rivers and the need for integrated approaches combining geomorphological context with socio-environmental indicators.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 3","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148786779","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}

Urban green spaces have been proposed as nature-based solution for mitigating particulate pollution, but evidence of their effectiveness at micro-scale in arid cities remains limited. We evaluated whether small urban green spaces are associated with local reductions in PM2.5 concentrations in an arid South American city. PM2.5 was measured during six mobile monitoring campaigns in winter 2026 along a 4.3 km urban transect comprising 75 georeferenced sampling locations. Sampling sites were classified as urban green spaces or non-green urban areas based on surrounding vegetation cover. The effects of site type were evaluated using Generalized Linear Mixed Models, accounting for traffic intensity, distance to the nearest road, and repeated measurements across sampling days and locations. PM2.5 concentrations were significantly lower in urban green spaces than in non-green areas, with adjusted concentrations approximately 31% lower after controlling traffic-related variables. Spatial interpolation identified areas with lower PM2.5 concentrations around small plazas and parks distributed along the monitoring transect. These findings indicate that even relatively small urban green spaces can provide measurable local air-quality benefits in arid cities and highlight the usefulness of mobile monitoring for detecting fine-scale spatial variability in particulate pollution.","PeriodicalId":501,"journal":{"name":"Bulletin of Environmental Contamination and Toxicology","volume":"117 3","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148786810","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 species-specific accumulation patterns, the bioaccumulation factor (BCF) and metal accumulation index (MAI) were calculated, and non-carcinogenic health risks from soil exposure were estimated using the hazard quotient (HQ) and hazard index (HI). The results indicated significant differences in metal concentrations among tree species, with Morus sp. exhibiting the highest accumulation of Fe, Mn, and Ni, whereas Pinus sp. displayed the highest MAI values. Soil analysis revealed considerable spatial heterogeneity, with the highest Pb and Zn concentrations observed in high-traffic urban areas.
