This multiomics study investigates the adaptive responses of bacterium–phage interactions under varying oxidative and hydraulic stress during membrane backwashing and their biological contributions to biofouling. Oxidative and hydraulic stress distinctly shaped bacteria and phage diversity and community composition. Under moderate oxidative backwashing (300 ppm of NaClO), diversity was maintained, with increased antioxidant enzyme activities, extracellular polymeric substance (EPS) production, and quorum sensing (QS) signaling, promoting bacterial resilience and biofilm formation. In contrast, excessive oxidative stress (600 ppm of NaClO) reduced bacteria and phage diversity, disrupted antioxidant responses, and increased microbial sensitivity. Hydraulic stress predominantly influenced viral diversity and co-occurrence network topology, favoring the expansion of broad host-range phages and lysogenic lifestyles under combined stresses. Phage–bacterium interaction analyses highlighted phages’ adaptive preferences for hosts with high network centrality and broad ecological niches, which enhanced microbial interactions and resilience. Transcriptomic profiling demonstrated the early enrichment of genes associated with energy metabolism, ROS detoxification, and biofilm formation, followed by stabilization as biofilms matured. Phage-encoded auxiliary metabolic genes were involved in DNA repair, QS, and EPS biosynthesis, contributing to microbial adaptation through oxidative stress resistance and biofilm stabilization. Overall, these findings provide mechanistic insights into biofouling dynamics and highlight the need to optimize chlorine dosing to prevent suboptimal levels of microbial adaptation and biofouling.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"61 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713736","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}

Conventional remediation agents are often carried away by groundwater flow in high-permeability layers, making it difficult to access NAPL contaminants in low-permeability layers and are prone to generate secondary contamination. This study explores the use of dihydrolevoclucosenone (Cyrene), a bioderived green solvent, as an alternative to traditional remediating agents for NAPL remediation. Through microfluidic experiments and accompanying numerical modeling, we demonstrate that Cyrene enhances the dissolution and mobilization of NAPL contaminants, particularly in low-permeability zones, achieving residual NAPL reductions of up to 80% compared with water and Tween 80 solutions. These findings underscore Cyrene’s dual environmental benefits as an eco-friendly solvent for both treating solid waste (e.g., stalks) and for NAPL remediation, paving the way for sustainable and green solutions in environmental management.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"33 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143723556","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}

Among the contaminants of concern are polycyclic aromatic compounds (PACs), a toxic group of organic pollutants prevalent at high concentrations in bitumen. Here, we quantify PAC concentrations, loads, and yields in four rivers draining watersheds impacted by mining. These rivers also actively erode and incise the bitumen-bearing McMurray Formation, which has complicated previous attempts to distinguish natural from anthropogenic inputs. We collected 998 water quality samples from locations both upstream and downstream of mining, analyzed them for a broad suite of 48 unsubstituted and alkylated PAC homologues, and compared their compositional fingerprints to potential natural and anthropogenic sources. Erosion of bituminous outcrops, rather than industrial pollution, is the main driver behind PAC input and riverine transport, as supported by (i) discrepancies in loads and yields among watersheds with varying levels of industrial development, (ii) responses to hydrologic changes with respect to the distribution of mapped outcrops, and (iii) shifts in PAC relative abundances. This study presents evidence that PAC concentrations are primarily controlled by the presence of eroding bitumen-rich outcrops in conjunction with hydrographic profiles, rather than industrial impacts.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"19 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713737","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}

Various monitoring, reporting, and verification (MRV) protocols have been developed to assess the carbon credits of CDR projects within voluntary and compliant carbon markets. Many MRV protocols incorporate life cycle thinking, LCA methods, and data. This perspective examined recent LCA studies and MRV protocols published by main carbon registries, focusing on four critical land-based CDR methods: bioenergy combined with carbon capture and storage, biochar, enhanced rock weathering, and afforestation and reforestation. We compared the carbon accounting and environmental impact assessment methods employed in these LCA studies and MRV protocols to identify their methodological similarities and differences. Our analysis reveals that the LCA community can support MRV protocols by providing critical insights into baselines, additionality, uncertainty, multifunctionality, environmental safeguards, holistic emission factors, and overlooked carbon pools. We recommend that future LCA research prioritize timing, permanence, scaling, and dynamic modeling for CDR. Addressing co-benefit and land use change impact assessment will further benefit both LCA and MRV development. Collaboration between the LCA and CDR communities is essential for developing robust frameworks to support carbon markets and policymaking.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"4619 3 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143723555","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}

Although N2O consumption activities by diverse heterotrophic N2ORB have been detected, knowledge gaps remain about the phylogenies, physiologies, and activities of N2ORB. Here, we successfully enriched a methylotrophic N2ORB consortium under intermittent oxygen and N2O supplies. 15N tracer analysis showed that the N2O consumption activity of the enriched consortium was higher than its N2O production activity in the presence of either a single or multiple electron acceptors (i.e., nitrogen oxides). The observed maximum N2O consumption was 80.7 μmol·g-biomass–1·h–1. Quantitative PCR results showed that clade I nosZ bacteria overwhelmed clade II nosZ bacteria at high (0.41 mmol·min–1) and low (0.08 mmol·min–1) N2O loading rates. The dilution rate and N2O loading rate affected the microbial community composition and activity. A higher N2O loading rate stimulated active and oxygen-tolerant N2ORB that boosted N2O consumption by approximately 50% in the presence of oxygen. Metagenomic analysis unraveled the predominance of a novel methylotrophic N2ORB, possessing entire denitrifying genes and high-affinity terminal oxidase genes, from the reactor with a high N2O loading rate. The unique physiological traits of the consortium enriched by methanol shed light on a novel function─aerobic N2O consumption by N2ORB─and pave the way for innovative N2O mitigation strategies applying powerful N2O sinks in engineered systems.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"40 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713734","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}

We investigated the photochemical behavior of aqueous-phase cellular organic matter (COM) and extracellular polymeric substances (EPS) from cultured bacteria isolated from atmospheric PM2.5, focusing on their photochemical production of 3C*, 1O2*, and •OH. The molecular size and aromaticity of chromophores and fluorophores in COM and EPS increased with molecular weight (MW). Apparent quantum yields (ΦRI) of up to 10% and 5% were measured for 1O2* and 3C*, respectively, which are in the upper range of previously reported values. This indicated that COM and EPS contain photosensitizers that are highly efficient at producing 1O2* and 3C*. ΦRI and concentrations ([RI]ss) decreased with MW due to higher-MW molecules engaging in charge-transfer interactions that disrupt photochemical processes and oxidant production. Machine learning models were used to understand and predict oxidant production based on measurable optical and chemical properties of COM and EPS.

Reported log10 reduction values (LRVs) varied widely across and within technology categories. We summarize microbial performance by technology type; pathogen class (bacteria, virus, protozoa); and study setting (field or laboratory). Combined coagulation-disinfectant products had the highest LRV performance for bacterial (6.3) and viral (5.3) classes, and porous ceramic had the highest LRV for protozoa (3) when n > 3.

Analysis of survey responses calculated consumer willingness to pay using mixed logit models. Results demonstrate the importance of terminology on consumer willingness to pay and the consistency of preference for the term “purified water” across cities in the United States. Consumers were also willing to pay for potable recycled water to avoid or reduce water restrictions, although the magnitude was small. Shifting from the commonly used “recycled water,” a less preferred term, to “purified water” is expected to increase both consumer acceptance and willingness to pay for the exact same product.

Although much effort has been made on organic chloramines in chlorination, great discrepancies exist in occurrence, decomposition kinetics, and molecular-level mechanisms of N-chloroaldimines. Herein, we propose a high-throughput method integrating directional reduction to distinguish organic chloramines from the nontarget-analyzed CHNOCl compounds and identify 86.6% of the CHNOCl compounds as N,N-dichloramines, N-monochloramines, and N-chloroaldimines. N,N-dichloramines show higher instability than N-monochloramines and can decompose to N-chloroaldimines. Furthermore, we quantitatively demonstrate the slower decomposition of N-chloroaldimines (10–6 s–1) than N,N-dichloramines (10–5 s–1) with 1 order of magnitude, and both of them are sensitive to engineering conditions, e.g., pH and residual disinfectants. We find that residual disinfectants can accelerate the decomposition of N-chloroaldimines. Meanwhile, we unravel the significant roles of NH2-linked R groups on the decomposition pathways of N-chloroaldimines through experimental and theoretical perspectives. Alkyl chains linked to NH2 groups lead to only the formation of nitriles in N-chloroaldimine decomposition, whereas carbocycles or benzene rings could result in the formation of aldehydes. These key insights will enable the effective control of N-chloroaldimine-derived disinfection byproducts and future optimization of the disinfection process.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"60 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713589","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 meet this demand, the raw materials sector must increase current capacities and develop new capacities at untapped deposits. Understanding life cycle impacts is crucial to avoid severe environmental burden shifts in the future. Although site-specific life cycle inventories exist, they do not allow for a comprehensive global assessment of the Li sector, particularly in capturing technological developments. To address this, our study presents a life cycle inventory model for brines that maintains essential site-specific parameters while providing a global perspective. We define core parameters for site-specific modeling of Li carbonate (Li2CO3) production and develop a systematic approach to addressing data gaps. Our model employs a class-based structure for 30 mapped processes from the literature and quantifies environmental and technical flows. Overall, we cover 25 sites, representing 300 kilotonnes (90%) of current Li2CO3 production from brines and an additional 315 kilotonnes of potential future production. One key finding is that sites using direct Li extraction have 7-fold higher climate change impacts than sites using conventional technologies on average, while water scarcity impacts are doubled on average. The difference is a result of the larger brine mass required to be treated due to lower Li grades. Furthermore, our model allows the implications for Li-ion battery production to be analyzed.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"24 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143703137","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}
