Additionally, there is little evidence for the effects of microplastics under different climate warming scenarios. To address this knowledge gap, the effects of high-density polyethylene (HDPE) microplastics, in combination with different constant temperature regimes (10°C, 15°C, and 20°C) and a fluctuating regime (10 - 20°C over a 24h diel cycle) on the respiration rates, feeding rates, and movement speeds of <em>Gammarus pulex</em> and <em>Asellus aquaticus</em> were assessed. Respiration rates of <em>G. pulex</em> increased with temperature according to metabolic theory, but there was no evidence for increased respiration rates of <em>A. aquaticus</em> at higher temperatures. Overall, the respiration rates and movement speeds of <em>G. pulex</em> were higher than <em>A. aquaticus</em> but there was no evidence that microplastics independently, or in combination with experimental warming, influenced any of the responses tested. There is increasing evidence that some microplastic particles may not be harmful to aquatic biota, and the findings presented in this study indicated that further evidence about the effects of different microplastic types, in combination with other human-induced pressures, is required to better understand the hazards and risks associated with microplastic particles in the environment.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"29 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Understanding <em>E. coli</em> concentrations helps in assessing the overall health risks associated with waterborne diseases and developing effective water management strategies. Therefore, we developed the first large-scale model, GloWPa-Ecoli C1 to simulate <em>E. coli</em> loads and concentrations in rivers and apply this model to China. The model provides the first comprehensive overview of microbial water quality across China’s rivers. The model simulates <em>E. coli</em> concentrations in 2020 to range from 10^-1.2 to 10^6.3 CFU/L, with 45.6% to 78.1% of rivers exhibiting poor microbial water quality. Major hotspots of <em>E. coli</em> pollution are Haihe, Huaihe and Pearl River Basins. Direct discharge of human faecal waste contributes 80.2% of the total <em>E. coli</em> load, while directly discharged livestock waste accounts for 13.1%. To mitigate <em>E. coli</em> pollution in rivers in China, we recommend increasing human waste collection rates, expanding wastewater treatment plant (WWTP) coverage, phasing out primary treatment WWTPs and eliminating direct livestock waste discharge, particularly from smallholder farms. The study underscores the urgent need to improve microbial water quality in China's rivers. The findings provide actionable insights to inform policy development aimed at safeguarding water quality and public health.

However, the toxicity variations of CMAP compared to single pollution and the mechanisms underlying these changes remain poorly understood. Herein in this study, the toxicities of copper (Cu)/erythromycin (ERY) and lead (Pb)/norfloxacin (NOR) to earthworms (<em>Eisenia Fetida</em>) were investigated. These results indicated that a single exposure to ERY and NOR at environmental concentrations had negligible effects on physiological processes. Combined Cu/ERY exposure induced more significant oxidative stress, disrupted energy metabolism, and caused cellular damage than Cu alone, as indicated by altered antioxidant enzyme activities, malondialdehyde and adenosine triphosphate content, elevated reactive oxygen species levels, and apoptosis rates in coelomocytes. Conversely, these adverse effects were mitigated by Pb/NOR exposure compared to Pb treatment alone. Further analysis of the gut microbiota revealed that Cu/Pb-tolerant <em>Bacillus</em> spp. play a critical mediating role in the contrasting toxicity profiles. ERY reduced the abundance of <em>Bacillus</em> spp., diminishing their ability to secrete soluble phosphate to immobilize Cu in the gut and leading to increased Cu absorption and toxicity. NOR enriches <em>Bacillus</em> spp. in the gut, facilitating Pb immobilization and reducing Pb bioavailability and toxicity. The contrast toxicity profile revealed the response of the gut microbiota taxa is the primary determinant of the variation in CMAP toxicity. These findings advance our understanding of the impact of CMAP on soil organisms and highlight the need for comprehensive ecological risk assessments to inform regulatory strategies.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"16 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

The potential of these reactive materials was investigated through batch, column, and modeling tests. The materials were produced by disc milling of ZVI, sulfur (S), copper (Cu), and nickel (Ni) with molar ratios of 0.05 and 0.2. The reactivity of the materials was assessed through vapor degradation batch tests conducted under partially saturated conditions using trichloroethylene (TCE) as a model compound. Sulfidated materials with a 0.05 S/ZVI molar ratio were the most reactive, achieving up to 99% degradation of TCE vapors within 18 hours and first-order degradation constants of 5-5.7 d^-1. Compared to the non-sulfidated materials, sulfidated ones remained reactive even after aging by exposure to air for 30 days. In all tests, C₃-C₆ hydrocarbons were detected as main byproducts, indicating β-elimination as the dominant TCE degradation pathway, with minor dichloroethylene and vinyl chloride amounts from the hydrogenolysis pathway. To evaluate the use of sulfidated bimetals as Horizontal Permeable Reactive Barriers (HPRBs) for treating chlorinated vapors in the subsurface, TCE diffusion column tests were performed using a 5 cm thick reactive layer of S-ZVI-Ni. These tests demonstrated up to 70% degradation over 25 days. By integrating the column test results into an analytical model, it was estimated that an 18 cm HPRB could ensure up to 99% degradation of TCE vapors. These findings highlight the potential of S-ZVI bimetals as an effective passive mitigation system for reducing chlorinated solvent vapor emissions from the subsurface.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"58 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

The 0.1 μm polystyrene (PS) could accumulate in the testicular tissue and spermatogonia GC-1, while 1 μm PS was not easy to enter and accumulate in the testicular tissue and cells. Mice continuously exposed for 3-months to 0.1 μm PS demonstrated lower fertility and inhibited spermatogonium differentiation compared to control mice.

Histone methylation and autophagy-related pathways showed significant differences following PS treatment in testis tissue and GC-1 cells. Our findings suggest that chronic exposure to 0.1 μm PS inhibited spermatogenic cell differentiation and impaired fertility in male mice. We propose that abnormal epigenetic modifications in 0.1 μm PS exposed mice contributed to the dysregulation of glycolytic enzymes, and that the impaired autophagic pathway exacerbated the accumulation of glycolytic enzymes further. Glycolysis plays a critical role in the regulation of spermatogenic cell differentiation, and its regulation partially alleviated the impairments associated with PS exposure.

Mapping of MPs in different deposition zones in fresh water sediment is important to identify their potential sources, sink, and transport mechanism. In this study, MPs were analyzed in sediment samples from Arun, Tamor, and Koshi Rivers in eastern Nepal. A total of 78 samples from 26 sites were collected from three independent deposition regions i.e. recent deposition (R0), recent past deposition (R1), and past deposition (R2) during monsoon season in 2023. All samples were analyzed following standard methods involving drying, peroxidation, density separation, microscopic examination and chemical identification by FTIR. In all the river basins differences in MPs count, color, and morphology were observed in three deposition regions. In Tamor basin the MPs count ranged from 3140-9500 MPKg^-1, 3800-9420 MPKg^-1, and 3180-9700 MPKg^-1 in R2, R1 and R0 regions, respectively. The mean abundance was found higher in downstream especially in Koshi River. The predominant shapes, sizes, and colors found in all three river basins were fragment (52.5%), 20-100 μm (58.86%), and black (33.76%). The particles were identified as polyamide, polypropylene, polyvinyl chloride, polysulfone, nylon, and, polyether ether ketone. The pollution risk assessment indicated minimal MPs contamination upstream and moderate contamination downstream. Finally, principal component analysis (PCA) and land use and land cover change (LULC) data were utilized to identify the potential sources of MPs. Agricultural and anthropogenic sources were identified as major contributors to the MPs load. This study provided baseline data for MP concentrations and their potential sources in Arun, Tamor, and Koshi river sediments.

The research involved 2642 individuals aged 60 and older in China. Urine concentrations of arsenic (As), cesium (Cs), barium (Ba), thallium (Tl), and cadmium (Cd) were analyzed using ICP-MS. Liver function was assessed based on the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and albumin (ALB). To evaluate the individual and combined effects of these NEMs on liver function, linear regression, restricted cubic splines (RCS), weighted quantile sum (WQS), quantile g-computation (QGC), and Bayesian kernel machine regression (BKMR) models were utilized. Mediation analyses were conducted to explore the potential role of lipid profiles in NEM-liver function relations. Adjusted linear regression revealed positive associations of Tl with ALT (<em>β</em> = 0.044, 95 % <em>CI</em>: 0.022 to 0.066) and AST (<em>β</em> = 0.019, 95 % <em>CI</em>: 0.004 to 0.035), and negative associations of Cs (<em>β</em> = −0.015, 95 % <em>CI</em>: −0.020 to −0.010), Tl (<em>β</em> = −0.010, 95 % <em>CI</em>: −0.015 to −0.005), and Cd (<em>β</em> = −0.019, 95 % <em>CI</em>: −0.024 to −0.014) with ALB. The RCS model confirmed these linear relationships. Mixture models consistently demonstrated a positive association between the NEM mixture and ALT/AST, primarily driven by Tl, and a negative association with ALB, predominantly influenced by Cd. Mediation analyses suggested triglycerides and total cholesterol partially mediated the associations between Tl, the NEM mixture, and liver function.

In concrete, we selected two non-transformed human cell lines of fibroblasts and hepatocytes; Allivibrio fisherii, Dictyosphaerium chlorelloides, Emiliana huxleyi and Artemia salina. Using standardized toxicological tests, we studied the effect of HTF under two scenarios: 1) exposure cells to concentrations on the range from 0.1 to 15 μg/L for short periods (from 30 minutes to 72 hours) and 2) the same concentrations for 20 days. Additionally, we explored the toxic effect of two different HTF samples: commercial and thermal degraded HTF (used). Results proved that commercial is less toxic than used and that microalgae was extremely sensitive (IC50 around 3.5 μg/L) following of Allivibrio fisherii (IC50 around 200 μg/L), human cell lines (IC50 around 1,000 μg/L) and crustaceans (IC50 2,000 μg/L). The particularities of cell wall composition and the metabolic specialization justify the differences. Furthermore, a very interesting result was that exposure for 20 days produced greater damage than the same dose for periods of 72 hours in all the cell types studied.
