In this paper, the interactive toxicity of polystyrene (PS)-NPs and polylactic acid (PLA)-NPs with the typical Organic UV filters butyl methoxydibenzoyl methane (BM-DBM) on the intestinal health and metabolism of zebrafish (Danio rerio) was investigated at the tissue and molecular levels using wild AB zebrafish as a model organism. The results showed that both NPs and BM-DBM exposure alone or in combination induced different degrees of inflammatory symptoms in the zebrafish intestine, where PS and PS+B exposure groups also induced an imbalance of the zebrafish intestinal flora, causing a more severe intestinal inflammatory response than PLA and PLA+B. PS and PS+B also induced more metabolic pathways or differential metabolite alterations than PLA and PLA+B, respectively. The results of liver-related factor response showed that all exposure groups except PLA alone induced oxidative stress in liver tissue, and hepatic metabolic factors were also interfered with to varying degrees, with more severe organismal metabolic abnormalities induced in the PS and PS+B groups. The above reflected the liver friendliness of PLA, while highlighting the risk of hepatotoxicity of PS. Pearson correlation analysis proved that abnormal changes in metabolites such as lipids and lipid-like molecules due to changes in intestinal flora are most likely an important mechanism and cause of the abnormal response of intestinal and hepatic molecular indicators. We hope that our study will provide a basis for the ecological risk assessment of non-/biodegradable NPs and provide data support for the promotion of biodegradable plastics.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"89 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145077541","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}

However, the potential struc-ture-function relationship is still unclear. Here, four kinds of CDs rich in carboxyl (CDs-c), hy-droxyl (CDs-h), and different contents of amino structures (CDs-a_0.2, CDs-a_2), respectively, were prepared by regulating the raw reagent using microwave assisted method. In vitro assays indicated that CDs-c had the highest scavenging activities against KMnO4, DPPH, ·OH, and O2- radicals. The changes in the morphology and chemical structure of these CDs after the reaction with ·OH suggested that the carboxy-like structures play significant roles in radical scavenging and antioxidant activity. Additionally, the calculation of reaction energy barriers using Density Functional Theory (DFT) revealed that the interaction between the carboxyl group and free radi-cals occurred in a barrier-free manner, resulting in the highest radical scavenging activity. In subsequent hydroponic experiments, rice seedlings pretreated with CDs-c showed the highest activity in their antioxidant defense system (SOD: 13.13%; POD: 40.55%; CAT: 133.33%; flavo-noid: 6.93%) and a significant enhancement in resistance to salt stress (fresh weight: 14.16%; height: 26.90%; chlorophyll content: 12.74%).

However, the effects of its structural parameters on membrane stability and oil-water separation performance remains unclear. This study performed molecular dynamics simulations to elucidate the underlying microscopic mechanisms. Results revealed that GO and PA spontaneously assembled into a stable sandwich-like membrane structure, wherein a highly oxidized lamellar GO framework enhanced PA accommodation. PA adsorbed robustly onto the GO surface through dense oxygen-containing functional groups, cross-liking adjacent GO sheets to precisely control interlayer spacing and suppress GO self-scrolling. Simulations further revealed that reduced GO oxygen coverage accelerated water permeation, while increasing the PA mixing ratio significantly improved oil-water separation performance, yielding a water flux of 4.1 molecules ns-1 and a separation efficiency of 96.3%. Energy analysis demonstrated that PA content dominated membrane hydrophilicity, imposing higher energy barriers for oil permeation than water. PA functionalization substantially enhanced the oil-water separation capability of GO membrane, with theoretical maxima reaching 97.5% separation efficiency and 98.8% water purity. These findings confirmed the dual role of phytic acid in stabilizing GO nanomembranes and promoting selective permeation of water and oil. The theoretical data derived from this study offered critical input for macroscopic process modelling and provided a foundation for engineering applications through rational design of materials and separation units (e.g. membrane reactor) under realistic operating conditions.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"36 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145077544","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}

Since internalization is a prerequisite for inducing adverse effects, we investigated the roles of surface modifications and polymer composition in human liver cells (HUH-7). Our study compared the internalization and effects of a pristine polystyrene nanoplastic (PS50-NPLs), two carboxylated polystyrenes of different sizes (cPS50-NPLs and cPS100-NPLs), and two environmentally relevant nanoplastics derived from polyethylene terephthalate water bottles (PET-NPLs) and polylactic acid pellets (PLA-NPLs). Significant variations in cell internalization were observed, with cPS50-NPLs and PET-NPLs showing the highest levels, and PS50-NPLs the lowest. Interestingly, internalization alone did not correlate directly with the induced effects; only PET-NPLs and PLA-NPLs induced reactive oxygen species (ROS), genotoxicity, and increased cytokine release. These results suggest that while internalization is essential in assessing MNPL toxicity, harmful effects also depend on other particle characteristics. The notable impact of the true-to-life PET-NPLs and PLA-NPLs underscores the importance of using environmentally representative MNPLs to better assess the health risks associated with environmental MNPL exposure.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":"155 1","pages":""},"PeriodicalIF":8.131,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145077556","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}

These galls, covered by a silky film produced by the larva, exhibit a multivoltine life cycle, with induction occurring on expanded leaves throughout both dry and rainy seasons.

The composite, fabricated via a green co-precipitation method employing Azadirachta indica leaf extract, integrates reduced graphene oxide with a ZnCo2O4 spinel framework to enhance light absorption, surface reactivity, and charge carrier mobility. Structural, surface and optical analyses confirmed the formation of a crystalline spinel phase with rGO incorporation, yielding a high surface area and a narrowed band gap. Electrochemical studies revealed low charge transfer resistance, while radical quenching experiments identified •OH and O2•‒ as primary oxidative species. Under natural sunlight, the optimized system achieved 97% DBP and 96% BBP degradation within 180 min in model solutions and over 75% removal in industrial wastewater, with substantial mineralization confirmed by TOC analysis. LC-MS and GC-MS investigations elucidated the degradation pathways, indicating transformation into low-toxicity intermediates. The catalyst exhibited excellent stability and reusability over nine cycles without structural degradation.
