Barrier hazard can instead be understood as arising from portal formation: the probabilistic emergence of localized, persistent regions of epithelial vulnerability driven by sustained, time-dependent particle–interface interactions. Within this view, epithelial stress reflects an emergent population-level state rather than a deterministic property of individual particles. The Portal Index captures this state by integrating the time-varying probabilities of mechanical barrier perturbation, interface persistence, and conditional inflammatory amplification into a unified functional measure of barrier stress. Because the framework operates at the level of particle populations and explicitly incorporates temporal dynamics, it is applicable to both monodisperse and heterogeneous MPs/NPs and supports temporally resolved comparison across materials, exposure scenarios, and experimental systems.

Wastewater effluents, rich in dissolved organic matter (DOM), act as major DBP precursors, posing challenges for water reclamation. Pretreatment-enhanced or hybrid membrane systems have emerged as essential strategies to control DBP formation and ensure water quality. This mini review critically examines recent advances in microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverses osmosis (RO) membranes for controlling DBP formation. While NF and RO can achieve up to 90–99 % removal of dissolved organic matter (DOM) and effectively reduce DBP formation potential (DBPFP) by over 80 %, MF and UF alone are limited in NOM/DBPFP removal and typically require integration with coagulation or other pretreatment processes for significant DBP control. However, low-molecular-weight neutral DBPs like NDMA remain challenging, with rejection rates frequently below 40 %. Hybrid systems, including ozonation-NF and photocatalytic membrane processes, show enhanced DBP removal efficiencies of up to 95 %, while offering benefits in fouling control and operational stability. Despite these advances, challenges persist in scalability, cost, and the environmental sustainability of emerging membrane materials. Future research should prioritize the integration of advanced nanomaterials, machine learning-driven membrane design, and life cycle assessments to enable safe and economically viable DBP management in water treatment and reuse.</div></div>","PeriodicalId":52296,"journal":{"name":"Current Opinion in Environmental Science and Health","volume":"51 ","pages":"Article 100721"},"PeriodicalIF":6.6,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147388323","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}

Nitrogenous DBPs (N-DBPs) are generally more toxic than the DBPs without nitrogen. Recently, DBPs of more than two carbons (“higher-carbon DBPs”) have been reported, but the status of higher-carbon N-DBP research has not been reviewed. This review assembled 355 individual compounds/structures of emerging higher-carbon N-DBPs and summarized the occurrence, precursors, and oxidation treatment for the 12 major classes (196 compounds/structures), including halogenated aromatic/cyclic compounds (nitrophenols, anilines, benzoquinone imines, pyridines, pyrroles, imidazoles, indoles, and nucleobases), as well as aliphatic/aromatic/cyclic compounds featuring nitrile, amide, and imide functional groups. Almost half of the major higher-carbon N-DBPs were confirmed by standards, but mass spectrometry-based identification is also common. Chlorination was the most studied disinfection method for higher-carbon N-DBPs, followed by chloramination and pre-ozonation, while chlorine dioxide and UV were not commonly considered. The levels of higher-carbon N-DBPs in real water samples ranged from &lt;0.1 to ∼100 ng/L based on the limited studies, but their global occurrence remains unknown. Preliminary toxicity assessment showed that higher-carbon N-DBPs were more toxic than their non-nitrogenous analogues and the regulated DBPs. Potential synergy between the research of DBPs and contaminants of emerging concern (CECs) was discussed, as CECs can serve as a significant but previously overlooked source of precursors for both higher-carbon N-DBPs and the high-priority small-molecule DBPs. Strengthening the synergy between the research on DBPs and advanced oxidation processes (AOPs), especially regarding nitrogen-incorporation during AOP, will contribute to our understanding on the formation of higher-carbon N-DBPs.</div></div>","PeriodicalId":52296,"journal":{"name":"Current Opinion in Environmental Science and Health","volume":"49 ","pages":"Article 100690"},"PeriodicalIF":6.6,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145685643","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}

(2) what is the dual role of the plastisphere in pollutant fate, acting as both a transport vector and a bioreactor? (3) how are these functions intensified by global change drivers?
