In this Review, we develop a mechanism- and pathway-resolved perspective for evaluating how EPS govern horizontal gene transfer (HGT) of ARGs. Current evidence indicates that conjugation is the most directly supported pathway, with EPS facilitating or restricting transfer through effects on donor–recipient contact, matrix organization, and transfer-related physiology. For transformation, EPS-associated extracellular ARGs constitute reservoirs, but EPS–DNA binding can both preserve genetic material and limit its immediate bioavailability. By contrast, EPS involvement in phage-mediated transduction and vesicle-mediated transfer remains mechanistically plausible but insufficiently validated. We identify five interconnected mechanisms: physical retention and spatial organization, DNA adsorption and bioavailability, regulation of intercellular contact, modulation of cell physiology and transfer competence, and community-scale mobilome coupling. By clarifying evidence boundaries across pathways, this Review moves EPS–HGT research from correlation-based interpretation toward mechanism-informed assessment of ARG mobility. We conclude by outlining research needs, including standardized EPS definition and extraction, component-resolved characterization, pathway-resolved causal assays, and validation in realistic environmental aggregates.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"7 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374754","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}

Here, we combined tower-based vertical observations with process-resolved model simulations in Beijing across winter and summer. We find that AOC generally declined with height in both seasons, but radical concentrations exhibit opposite vertical gradients. Notably, enhanced biogenic volatile organic compounds (VOCs) emissions in summer suppress near-surface OH levels, creating a mid-altitude maximum. However, sharp vertical NO gradients drove an increase in ROx with height in winter. The underlying chemistry of vertical AOC variation shifts with the seasons. In winter, the photolysis of HONO dominates ROx production, and NOx-driven ROx loss prevails. In summer, the photolysis of oxygenated VOCs takes over, with radical self-reactions as the primary ROx sink. These findings demonstrate that surface observations alone may provide an incomplete representation of the whole boundary-layer chemistry.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"14 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374760","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}

Despite the growing interest in using these capabilities to address environmental and sustainability challenges, the broader potential of CRISPR in environmental systems remains unexplored relative to its biomedical applications. Here, we provide a critical perspective on the emerging use of CRISPR for pollution management, ecological conservation, and environmental monitoring. Rather than viewing CRISPR solely as a gene-editing or biosensing technology, we consider both capabilities together to examine how advances in CRISPR engineering can translate into practical environmental solutions. We highlight the fundamental principles behind CRISPR-based editing and sensing and evaluate the challenges that constrain their transition from proof-of-concept experiments to field deployment, including off-target effects, delivery methods, ecological risks, and low sensitivity. Addressing these hurdles requires a multifaceted approach that integrates emerging technologies such as reversible CRISPR technology, amplification and cascade reactions, and machine learning, with strict regulatory oversight and rigorous risk assessments. This perspective identifies critical strengths, weaknesses, and research priorities for advancing CRISPR from laboratory technology toward robust tools for environmental applications.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"9 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374761","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}

Here, we investigate an ionizing radiation-assisted Fenton process (IRFP) in which radiolytic Fe redox cycling sustains Fe-mediated oxidation. Using sulfasalazine as a model pollutant, we demonstrate that radiolytically generated hydrated electrons support two coupled pathways: rapid H2O2 activation and the conversion of Fe(III) to Fe(II). The resulting Fe redox cycling dynamically replenishes the Fe(II) pool alongside radiolytic H2O2 activation, thereby sustaining oxidative transformation beyond the initial degradation stage. Compared with irradiation and conventional Fenton treatment, IRFP promoted deeper fragmentation of azo, sulfonamide, and aromatic structures, resulting in enhanced mineralization. Transformation-product analysis further showed that continued transformation in IRFP reduced the persistence of complex intermediates with elevated predicted toxicity. In real pharmaceutical and coking wastewaters, IRFP achieved effective treatment under near-neutral conditions with substantially lower H2O2 and Fe(II) requirements than Fenton treatment and lower absorbed doses than irradiation alone. Although its electricity demand remained higher than short-time Fenton treatment, the markedly lower dosage of chemicals reduced the potential iron sludge burden and resulted in lower estimated COD-normalized treatment costs under the investigated conditions. These findings establish radiolytic Fe redox cycling as a strategy for sustaining Fe-mediated oxidation and promoting deeper transformation and mineralization of refractory pollutants.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"20 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374757","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}

Here, we characterize the photochemistry of performic acid (PFA) under 222 and 254 nm irradiation and evaluate the capacity of PFA solution, prepared from H2O2 and formic acid and thus containing residual H2O2 and formate, to generate concurrent oxidative and reductive pathways. Relative to 254 nm, 222 nm irradiation increased the fluence-normalized photodecay rate constants of neutral PFA (PFA0) and its conjugate base (PFA–) by 1.21- and 3.81-fold, respectively. The increase arose from 16.1- and 10.1-fold larger molar absorption coefficients at 222 nm, despite lower fitted innate quantum yields (0.367 and 0.804 molecule photon–1 at 222 nm versus 0.587 and 0.819 molecule photon–1 at 254 nm). The UV222/PFA solution system generated the reductant •CO2– together with oxidative HO• and oxygen-centered organic radicals. Pathway analysis attributed 34% of carbamazepine removal to •CO2– and 19% of naproxen removal to R-O• at 222 nm. Chloride and bromide enhanced fluence-normalized degradation through reactive-halogen chemistry; the largest increases were observed for carbamazepine (47.5-fold at 254 nm and 21.9-fold at 222 nm). In real municipal wastewater, UV222/PFA solution decreased total organic carbon by 33.5% within 60 min, compared with 21.6% under UV254/PFA solution, at an initial PFA concentration of 80 μM. These results suggest far-UVC activation of PFA solution as a dual-redox treatment platform, with the observed advantages maintained in the tested wastewater effluents.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"37 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374756","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}

Microplastic fragments rapidly redistributed─exiting the water column and settling on the bottom and shorelines. A particle budget across the water column, bottom sediments, and beaches accounted for 77% of the polyethylene, 48% polystyrene, and >100% polyethylene terephthalate. “Missing” plastic was likely in the nearshore littoral. Our observations suggest that if we prevent further inputs to aquatic ecosystems, microplastics will quickly disappear from the water column─washing up on shorelines and settling on the bottom.

Here, we report a full-season field trial comparing UAV and manual imidacloprid (IMI) application in paddy rice, simultaneously tracking grain residue dynamics and occupational exposure in 29 applicators through to harvest. Grain IMI concentrations at harvest were comparable between regimes (86−115 μg/kg) and exceeded the EU maximum residue limit (MRL, 10 μg/kg) in both groups. More critically, on an LC-HRMS-derived relative-concentration basis, parent IMI accounted for 30.4% of the detected IMI-related profile in grain, whereas transformation products collectively accounted for 69.6%. Among these, 6-hydroxynicotinic acid was the single highest-abundance compound, surpassing parent IMI itself, yet none of the detected transformation products are included in China’s residue definition for imidacloprid in plant-derived foods. Regarding occupational exposure, urinary IMI rose approximately 9-fold from pre-exposure baseline in UAV operators compared with 17-fold in manual applicators. Manual application also induced markedly greater lipid peroxidation stress, with median baseline-normalized MDA fold changes of approximately 3.8- and 2.6-fold in the manual and UAV groups, respectively (p = 0.001). These findings establish that application technology substitution effectively reduces occupational exposure risk but confers no advantage at the food safety end point. Current parent-compound-centered residue surveillance frameworks systematically underestimate the true IMI-related burden in harvested grain, and expansion of regulatory monitoring beyond the parent compound is warranted.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"10 2 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374758","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}

To address this, this work proposed a distributed optical fiber vibration sensing system based on phase-sensitive optical time-domain reflectometry (Φ-OTDR) for drainage pipeline monitoring. To accurately capture abnormal events from complex environmental noise, a two-tier intelligent processing architecture comprising localization and classification modules was developed. The localization module employed an enhanced You Only Look Once (YOLO) model integrating anchor-box optimization, a channel-attention module, and an additional small-target feature layer, achieving a mean average precision of 96.8% in laboratory tests. The classification module utilized a hybrid model combining convolutional neural network, bidirectional long short-term memory, and attention classifier, achieving an overall accuracy of 98.1% for five abnormal events. During two-week of continuous field monitoring, the system localized simulated events with errors below 2.60 m and distinguished internal leakage, knocking, and drilling from walking, running, and vehicle interference with precision and recall exceeding 99.6% for the tested classes.

Herein, we engineer sulfur-vacancy-rich MoS2 (Sv-MoS2) electrodes to expose coordinatively unsaturated Mo sites and enable an efficient Mo–H*-mediated dechlorination pathway. Using florfenicol as a model chlorinated antibiotic, Sv-MoS2 achieved near-complete dechlorination with ∼15-fold faster kinetics than pristine MoS2, reaching a rate constant of 9.26 h–1 at low energy consumption (0.0083 kWh g–1). Mechanistic analyses combining CV, EPR, in situ Raman spectroscopy, kinetic isotope effects, and DFT calculations reveal a dual-site H* utilization mechanism: S sites primarily generate H*, while vacancy-exposed Mo sites stabilize Mo–H* species that selectively drive C–Cl bond cleavage. In contrast, pristine MoS2 follows a direct electron transfer-dominated pathway and shows limited deep dechlorination. The Mo–H*-mediated pathway on Sv-MoS2 substantially lowers the energy barriers for sequential C–Cl cleavage while promoting productive H* utilization over H2 formation. The Sv-MoS2 electrode further exhibits robust performance under variable pH, natural organic matter, coexisting anions, and repeated cycling. This work clarifies Mo/S site synergy in MoS2 electrocatalysts and establishes a dual-site design framework for efficient, selective, and sustainable electrochemical hydrodechlorination.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"23 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374763","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}

Peroxymonosulfate (PMS) activation had attracted broad interest as a route to •OH generation because of its asymmetric O–O bonds and ease of storage and transport. However, conventional Fenton-like activation of PMS typically produced •OH through a two-step pathway involving sulfate radicals (SO4•–), which incurred kinetic losses and limited •OH availability. Here, we reported a one-step •OH generation pathway from PMS enabled by synergistic polarization effects. This electronic regulation increased the O–O bond dipole moment from 0.45 to 3.86 D and produced a steady-state •OH concentration more than 2 orders of magnitude higher than those reported for representative state-of-the-art Fenton-like systems. Mechanistic analyses revealed that the amplified dipole promoted heterolytic O–O bond cleavage, thereby bypassing the SO4•– intermediate and enabling direct •OH generation. This system achieved efficient removal of diverse organic pollutants and increased rate constant of oxidant activation by 175–400% higher than the values reported for representative PMS/PDS-based Fenton-like systems. Life cycle assessment further revealed a lower environmental footprint, attributed to improved chemical utilization rates. This oxidant-centered strategy provided a promising route to utilize dipole polarization for efficient generation of •OH, with the potential to achieve scalable and low-carbon advanced oxidation water remediation.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"504 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2026-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149368109","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}
