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}

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-HT<sub>1</sub>A-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.

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.
