Here, we investigated the interactive toxicity of polystyrene nanoplastics (PS-NPs, 80<ce:hsp sp=\"0.25\"></ce:hsp>nm) and elevated temperature (32 °C vs 25 °C) in marine medaka larvae (<ce:italic>Oryzias melastigma</ce:italic>) using integrated bioaccumulation analysis, histopathology, and transcriptomic profiling. Our results revealed that the digestive tract served as the primary tissue for NPs bioaccumulation, with elevated temperature significantly accelerating particle bioaccumulation (1.20 to 6.27-fold increase) and exacerbating shedding of intestinal villi. Transcriptomic analysis identified temperature as the dominant driver of transcriptional remodeling, while co-exposure induced unique synergistic effects not observed under individual stressors. Specifically, combined exposure amplified immuno-inflammatory responses through complement cascade and phagosome pathways, with NPs perceived as pseudo-pathogenic threats triggering respiratory burst and apoptosis. Concurrently, antagonistic interactions suppressed critical protective responses including heat shock protein <ce:italic>hsp90α1</ce:italic> and immune regulators (i.e., <ce:italic>il2rg</ce:italic> and <ce:italic>ptx3</ce:italic>). Most concerning, co-exposure uniquely enriched multiple cancer-related pathways absent from individual stress conditions, with synergistic upregulation of the proto-oncogene <ce:italic>myc-2</ce:italic>. These findings demonstrated that elevated temperature fundamentally altered NPs toxicity from localized intestinal stress to broad immuno-inflammatory dysregulation, creating a transcriptional state associated with cancer-related pathways. Additionally, a phenotypic interaction analysis on catalase (CAT), superoxide dismutase (SOD), malondialdehyde (MDA), reduced glutathione (GSH) and intestinal villus morphometry (length and width) showed that the standardized Cohen's d interaction indices followed a consistent trend matching transcriptome-level predictions of synergistic antioxidant induction and barrier impairment. Our results highlighted that current single-stressor risk assessments underestimate NPs threat under climate change scenarios, emphasizing the urgent need for multi-stressor frameworks in environmental protection.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"10 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149087313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Phase-resolved mass balances were combined with electron paramagnetic resonance (EPR) and surface characterization to examine tetrachloroethene (PCE) redistribution and removal. In homogeneous aqueous systems, PCE removal was rapid within 2<ce:hsp sp=\"0.25\"></ce:hsp>h, with rapid dissolved Fe(II) consumption. Among evaluated Fe(II):PDS ratios, 1:1 yielded the highest removal, with >30% PDS persisting beyond the initial stage. Following Fe(II)/PDS addition to pre-equilibrated soil–water systems, aqueous PCE increased while soil-associated PCE decreased and total PCE mass declined monotonically. SEM–EDS, FTIR, and XRD indicated Fe-rich surface deposition and altered organic functional groups, supporting interfacial changes that weaken PCE retention. Soil addition attenuated EPR spin-adduct responses. In pre-equilibrated systems, the fitted sulfate-adduct response in soil extracts exhibited negligible variation between 10 and 120<ce:hsp sp=\"0.25\"></ce:hsp>min, consistent with continued soil-associated activation as intensive aqueous oxidation subsided. These observations support a kinetic mismatch between declining effective oxidative capacity and continued soil-to-water PCE release, allowing aqueous accumulation despite net removal. The findings provide a mechanistic basis for coordinating reagent transport and local activation with delayed contaminant release through alternating PDS and Fe(II) injection in groundwater circulation well (GCW) systems.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"24 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149087312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
