Accurate environmental monitoring requires robust analytical strategies supported by rigorous statistical validation. This study presents a novel analytical-statistical framework for CEC quantification, evaluating different linear model fitting, matrix effects, and calibration methodologies: post-sample treatment standard addition (ESAC) and ESAC with internal standards (ISC). Our findings demonstrate that weighted least squares (WLS) regression provided the most accurate model fitting. The ISC methodology, combined with WLS, outperformed other approaches in linearity and validation parameters, effectively minimizing matrix interference. This validated framework was subsequently applied to surface water and biota samples. Surface water analysis revealed significant anthropogenic pressure linked to tourism and maritime activities. In certain areas the level of pharmaceuticals was lower (8.4 μg·kg^-1), in contrast to pesticides (6.2 μg·kg^-1). Among biota, crabs exhibited the highest bioaccumulation (334 μg·kg^-1), followed by adult mussels (247 μg·kg^-1); notably, no direct correlation with trophic levels was observed. These results confirm that the proposed ISC-WLS approach provides a reliable and high-precision tool for the environmental assessment of CECs in complex matrices.</p>","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":" ","pages":"128251"},"PeriodicalIF":7.3,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147831845","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}

We conducted a hospital-based prospective cohort study of 3,770 Chinese men who underwent 4,847 semen examinationin in Chongqing, China (2018-2023). Exposure to PM_2.5 and its components (SO₄^2-, NO₃^-, NH₄⁺, OM, BC) was estimated for the 0-90 days preceding semen collection, while residential greenness was assessed using satellite-derived normalized difference vegetation index (NDVI) over the same period. Semen quality parameters including progressive motility, non-progressive motility, total motility, sperm concentration, total sperm count, and viability, were assessed according to WHO 5th edition guidelines. Linear mixed-effects models were used to examine associations between environmental exposures and semen quality and their interactions. Higher exposure to PM_2.5 and its components was associated with poorer semen quality, including reduced progressive motility, sperm concentration, sperm count, sperm viability, and total motility. For instance, per IQR increase in PM_2.5 was associated with a 2.0% decrease in progressive motility (-3.7%, -0.3%) and a reduction in total sperm count of 0.108 million sperm (-0.160, -0.056). In contrast, higher residential greenness was positively associated with total sperm count. Significant interactions were observed between greenness and PM_2.5 or SO₄^2- for progressive and total sperm motility, with higher greenness mitigating adverse effects, particularly at lower SO₄^2- levels.

These contaminants are in proximity to human activities and tend to accumulate in sediments, which further amplifies their ecological impacts on freshwater ecosystems. Nevertheless, most studies have focused on the effects of single or pairwise stressors, leaving the effects of complex higher-order interactions on macrophyte communities scant. Here, we conducted a full-factorial experiment using 96 glasshouse mesocosms in 10 L systems containing two macrophyte species (Lemna minor and Spirodela polyrhiza) maintained in a controlled glasshouse environment to investigate the single and higher-order interactive effects of the three emerging contaminants, including microplastics, antibiotics, and antiviral drugs, on two common free-floating macrophytes and their interactions. Our results show that individual and combined stressors cause species-specific responses in free-floating macrophytes, thereby directly or indirectly altering community dominance patterns. Multiple stressors mainly showed antagonistic interactions, triggering negative feedback regulation that alleviated macrophyte growth inhibition. And the feedback is context-dependent, as changes in environmental conditions and stressor combinations may reverse these feedback patterns, potentially enhancing ecological toxicity. Our findings highlight that the inherent complexity and unpredictability of higher-order interactions among multiple stressors can heighten risks to macrophyte communities. We advocate that evaluations of multiple stressors in freshwater ecosystems should integrate context-dependent responses, stressor interactions, and feedback due to redundancy and compensatory dynamics. Future studies should incorporate both biotic and abiotic stressors across multiple gradients and higher ecosystem levels, accounting for non-linear and context-dependent responses.</p>","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":" ","pages":"128286"},"PeriodicalIF":7.3,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147831778","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}

Triadimefon caused dose-dependent growth inhibition and multi-tissue injury, including epidermal ulceration, muscular disorganization, and intestinal lesions. Ultrastructural observations and oxidative stress analyses further showed cytoplasmic vacuolization, mitochondrial and other intracellular organelle damage, disruption of antioxidant defenses, and increased oxidative DNA damage under high-dose exposure.

However, the mechanisms underlying their induction of emotional disorders remain poorly understood. In particular, intervention-oriented and functionally validated strategies for prevention and control are still lacking. To address this, we conducted a 28-day repeated oral exposure study in mice using a gradient of polystyrene nanoplastics (PS-NPs; 2, 10, and 50 mg/kg/day) spanning environmentally relevant doses, systematically assessing impacts along the microbiota-gut-brain axis. Our results showed that PS-NP exposure induced dose-dependent anxiety- and depression-like behaviors, with fluorescence tracing revealing predominant gut accumulation and limited brain distribution. Mechanistically, exposure induced gut microbiota dysbiosis, intestinal barrier impairment, and lipopolysaccharide translocation, ultimately leading to systemic inflammation and neuroinflammation. Serum biochemical analysis showed that gut dysbiosis initiates host tryptophan metabolism toward the kynurenine pathway by triggering inflammation and subsequent indoleamine 2,3-dioxygenase 1(IDO1) activation. Consistently, hippocampal transcriptomic and biochemical analyses confirmed decreased 5-HT levels and suppression of the downstream 5-HT₁A-cAMP-PKA-CREB-BDNF neurotrophic cascade, demonstrating comprehensive serotonergic disruption from substrate depletion to receptor dysfunction. Notably, the prebiotic galacto-oligosaccharides (GOS) restored intestinal homeostasis and ameliorated these anxiety- and depression-like behavioral and metabolic deficits, exerting protective effects by counteracting above pathway. Our work delivers a from-mechanism-to-solution understanding: it deciphers how microplastics disrupt the gut-brain axis to cause neurotoxicity and identifies GOS maintenance of intestinal health as a key mitigative strategy against plastic pollution risks. Therefore, maintaining intestinal health, particularly through dietary GOS, represents a viable strategy to mitigate the neurotoxicity induced by plastic pollution.</p>","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":" ","pages":"128276"},"PeriodicalIF":7.3,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147831829","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}

We examined metformin degradation and its effect on prokaryotic communities under diverse controlled oxygenation conditions in laboratory microcosms mimicking the sediment–water interface. In autoclaved microcosms, metformin showed slow dissipation without significant formation of transformation products, irrespective of oxygenation conditions. In contrast, biotic microcosms showed metformin biodegradation within 13 days following a lag phase of up to 28 days. Degradation was faster under anoxic conditions. Guanylurea was the sole transformation product detected, suggesting enzymatic hydrolysis and potential use of dimethylamine and guanylurea as carbon and nitrogen sources for microbial growth. Prokaryotic community composition was significantly affected by oxygenation conditions and repeated metformin contamination. Metformin exposure and changes in oxygenation regime had predominantly additive effects. Nevertheless, non-additive effects on procaryotic community composition emerged over time, particularly after repeated metformin exposure. Twenty-one bacterial taxonomic biomarkers of metformin exposure were tentatively identified, including methylotrophic taxa potentially associated with the utilisation of metformin and its metabolites. Microbial activity was essential for metformin dissipation at the sediment–water interface, and oxygenation regime modulated the effect of metformin and its transformation on prokaryotic communities.
