Contrasting toxicity mechanisms of combined antibiotic and metal pollution on Eisenia Fetida","authors":"Qiuyun Xu, Xin Xiong, Yajuan Shi, Li Qian, Xuan Zhou, Xueli Tian, Jinyang Yu, Liuxuan Fang","doi":"10.1016/j.envpol.2025.126166","DOIUrl":"https://doi.org/10.1016/j.envpol.2025.126166","url":null,"abstract":"The pervasive occurrence of combined metal and antibiotic pollution (CMAP) in agricultural soils is increasingly being recognized as a novel threat to ecosystems. 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}

Microplastics accumulate in animals and humans, but the risks associated with these pollutants are not fully understood. This study aimed to investigate the effects of polystyrene microplastics on the male reproductive system. 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. The 0.1 μm PS were dispersed throughout the seminiferous tubule of the testis. Metabolic reprogramming was found to be involved in these processes. 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. In conclusion, our findings suggest that chronic exposure to nanoplastics PS inhibited spermatogenic cell differentiation and impaired fertility in male mice via disrupted epigenetic modification and metabolic dysregulation.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"6 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766601","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}

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. This information could be important for future MPs mitigation strategies.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"27 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766550","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}

Although they are thought to be clean, the analysis of its life cycle evidence a negative impact on the environment, due to unvoluntary spillages of heat fluid transfer (HTF). To know the risk of HTF spills for human health and environment, we selected human cell lines and toxicological model organisms to evaluate both aspects. 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. Our results suggest that HTF spillages have a bigger environmental impact than expected, which thermosolar plants are not as environmentally friendly as previously thought.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":"18 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766909","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}

Heavy metal pollution index (HPI), heavy metal evaluation index (HEI), degree of contamination (CD), and health risk assessment were utilized in this study to present the findings of a thorough assessment of heavy metal contamination in the region. Meanwhile positive matrices factorization (PMF) was applied to ascertain sources of heavy metals in influent sewage. The results showed that sewage treatment diminished pollutant concentrations. After treatment, Zn, Hg, Pb, and Cr were the primary contaminants in the effluent sewage, significantly surpassing the Class I standard limit for surface water in China. The primary sources of sewage contamination were anthropogenic activities, including agriculture, industry, and transportation. The cumulative health risk from carcinogenic heavy metals surpassed the permissible danger threshold. Cr was responsible for majority of health hazards.

In contrast, other aquaculture areas, particularly NJ, exhibited lower pollution levels in water, sediment, and fish muscle, reflecting a more favorable environment for fish farming compared to ND. Seasonal analysis showed a decline in essential metals (Ca, Fe, Cu, Zn) during summer, with recovery in autumn and winter, while toxic metals (As, Cd, Pb, Hg) accumulated in autumn and winter. Additionally, Trophic levels in water and sediments peaked in summer and autumn, displaying region-specific variations.
