The accurate analysis of EFRs in marine matrices remains challenging due to the inherently low sensitivity and selectivity in complex matrices, matrix-induced signal suppression, limited analytical throughput, and the lack of robust non-target screening protocols. This review provides an integration of recent methodological breakthroughs, encompassing sensitive instrumental approaches and innovative extraction and purification techniques for EFR detection in marine multi-matrix. The environmental occurrence and process of EFRs highlight that the roles of particle-mediated transport, plastic debris leaching, and photochemical degradation co-govern the fate of EFRs in marine environments. Furthermore, the review critically examines the ecological risks of EFRs, focusing on their bioaccumulation-driven toxicity, trophic magnification in marine food webs, and the potential for ecosystem destabilization. Mechanistic insights into photochemical transformation pathways are summarized, highlighting the formation of persistent and more toxic products that raise risks of chronic exposure and ecological disruption in marine environment. It provides a scientific foundation for regulatory agencies to assess marine environmental risks and implement targeted mitigation strategies. Future research should focus on quantifying the ecological impacts of EFRs to support a more effective monitoring and management framework.</div></div>","PeriodicalId":29813,"journal":{"name":"Eco-Environment & Health","volume":"4 4","pages":"Article 100186"},"PeriodicalIF":17.6,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145332931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the interactive mechanisms underlying their combined pollution in soil–plant systems remain elusive. To fill this gap, this study investigated the interaction between submicron plastics (SMPs, 0.01% and 0.1% w/w) and di(2-ethylhexyl) phthalate (DEHP) in soil–lettuce systems. Contrary to the anticipated synergistic toxicity, DEHP significantly reduced SMP uptake into and by cracked surface cells of lettuce roots (with root concentration factors decreasing by 19%–64%), i.e., DEHP alleviated SMP-induced oxidative stress, as evidenced by reduced levels of reactive oxygen species (−26.8% and −66.7%) and antioxidant enzyme activities (−118% and −128%). Metabolomic profiling revealed that SMP exposure significantly dysregulated multiple metabolic pathways (amino acid, carbohydrate, energy, glycan, lipid, and nucleotide metabolism), while SMP ​+ ​DEHP co-exposure selectively attenuated these metabolic disturbances, showing enrichment only in glycan biosynthesis/metabolism and suppressing SMP-induced perturbations in other pathways (biosynthesis of secondary metabolites, energy metabolism, and signal transduction). Microbial community analysis showed that high-level SMP exposure significantly diminished bacterial α-diversity and amplicon sequence variant (ASV) richness, whereas DEHP supplementation enhanced those of <em>Myxococcota</em> in the soil, potentially counterbalancing SMP-induced microbial dysbiosis. These findings collectively demonstrate that co-contamination by MNPs and plastic additives may produce antagonistic interactions rather than uniformly synergistic effects, and provide a more comprehensive evaluation of the risks of PAEs and MNPs to food security, human health, and ecological environment.</div></div>","PeriodicalId":29813,"journal":{"name":"Eco-Environment & Health","volume":"4 4","pages":"Article 100184"},"PeriodicalIF":17.6,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145227171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Temperature plays a significant role in biofilm development and microbial dynamics. However, comprehensive studies on the effects of temperature on marine plastic biodegradation remain limited, as most research focuses on individual and moderate temperatures, overlooking how temperature variations across polar to tropical marine environments interact with other ecological factors to influence plastic biodegradation. This review summarizes current research on temperature-induced biofilm formation, microbial succession, and enzymatic depolymerization of plastics. The findings reveal that higher temperatures generally enhance biofilm growth. Notably, cold-tolerant bacteria stimulate the production of extracellular polymeric substances (EPS) to stabilize biofilms and adapt to cold conditions. Microbial succession, particularly within the Proteobacteria phylum, is primarily regulated by temperature, driving shifts in microbial diversity and activity. For different types of plastics, the hydrolyzable ones are degraded via enzymes such as cutinases, lipases, and depolymerases, mostly at mild temperatures. In contrast, non-hydrolyzable plastics are relatively recalcitrant to enzymatic breakdown but can be biodeteriorated by enzyme-generated reactive oxygen species (ROS), with minimal temperature influence due to their slow biodegradation. This review emphasizes the critical role of temperature in biodegradation processes and prospects for promising strategies for improving marine plastic management under the changing climate.</div></div>","PeriodicalId":29813,"journal":{"name":"Eco-Environment & Health","volume":"4 3","pages":"Article 100177"},"PeriodicalIF":17.6,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144912187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study first measured the heterogeneity in inactivation kinetics and biological mechanisms of four typical viral surrogates (MS2, phi6, phix174, and T4) to various ROS by visible light catalysis. Notably, the second-order inactivation rate constants of four viruses by hydroxyl radicals (·OH), singlet oxygen (¹O₂), and superoxide radicals (·O₂⁻) were quite different: 10⁹–10¹⁰, 10⁷–10⁸, and about 10⁵ ​M⁻¹ ​s⁻¹, respectively. The susceptibility of four viruses to ROS varied significantly, in the order of phi6 ​&gt; ​MS2 ​&gt; ​phix174 ​&gt; ​T4. More importantly, ¹O₂ can better oxidize capsid proteins. ·O₂⁻-induced RNA damage was significantly greater than that to the DNA genome, indicating that RNA viruses are more susceptible. ·OH can strongly inactivate the four structurally distinct viruses. Furthermore, the resistance of the ROS-inactivated virus to environmental interference was assessed in detail.

Metagenomics enables high-throughput pathogen identification by mapping sequencing reads to known pathogen genomes.

Here, we developed a novel, virulence factor (VF) based machine learning method using the K-Nearest Neighbors model (VF-KNN) for identifying human pathogenic bacteria from soil metagenomes. Through learning the VF features of pathogenic and non-pathogenic bacteria, VF-KNN could achieve the desired performance in soil pathogen identification (AUC: 0.95, Accuracy: 0.85). Model prediction accuracy (0.95) was further validated using 61 pathogenic strains isolated from soil. For the top 15 most frequent soil pathogens, the prediction accuracy was >0.90 ​at 0.4X-1.0X genome coverage. VFs contributing significantly to pathogen identification were associated with regulation, effector delivery, motility, etc. By using VF-KNN, the averaged abundance of total potential pathogens in topsoils across China was 0.44% (<i>n</i> ​= ​336), predominantly concentrated in the eastern coastal provinces. Compared with the conventional method based on a predefined pathogen list, VF-KNN identified 28% more potential pathogenic species, including some newly reported but not in the predefined list (e.g., <i>Mycolicibacterium cosmeticum</i>).
