This study proposes a spatiotemporal graph learning framework for detection and localization of external inflows in urban sewer systems. The framework combines three inputs: (i) the inflow-affected water-level time series from one downstream sensor, (ii) simulated baseline water-level series for all upstream nodes generated using EPA SWMM, and (iii) a weighted graph representation of network topology. An LSTM-GCN regression module first estimates the event-level maximum water-level deviation at each node rather than the full deviation time series, improving robustness to unknown inflow hydrographs. A downstream GCN classifier then converts the inferred spatial response into branch-level probabilities for source localization. The method was evaluated in a synthetic 117-junction test network and a 39-junction real-world sewer subnetwork. In the synthetic single-source case, the true source branch was ranked within the top two candidates in over 90% of test events. In the real-world case, the Top1 branch localization reached 100%. Sensitivity analyses further showed that larger inflow magnitudes and hydraulically coherent branch partitioning improved localization reliability. These results demonstrate the potential of graph-based single-sensor diagnostics for low-cost sewer monitoring and targeted inspection planning.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"301 ","pages":"126105"},"PeriodicalIF":12.8,"publicationDate":"2026-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147969314","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 explore this question, we integrated hydrogeochemical characterization, carbon isotopic tracing, metagenomic analysis, and pathway-specific enrichment experiments, focusing on MeAs-rich alluvial-lacustrine aquifers in the central Yangtze River Basin. A strong positive correlation between arsM and mcrA abundances (r = 0.84, p < 0.001) points to a co-occurrence of genetic potential for arsenic methylation and methanogenesis in the studied aquifer. Metagenome-assembled genome (MAG) analysis showed a pathway-specific distribution of arsM gene, a higher proportion of acetoclastic methanogen MAGs harbored complete arsM genes (14.29 %), compared to methylotrophic (9.09 %) and hydrogenotrophic (0.00 %) methanogens. In pathway-specific enrichment assays under controlled laboratory conditions, acetoclastic cultures exhibited the highest capacity for stepwise arsenic methylation (MMA and DMA production), with methylation efficiency reaching approximately 10.2 %, whereas methylotrophic cultures produced only transient MMA and hydrogenotrophic cultures showed minimal methylation. These observations provide insights into pathway-dependent differences in methanogen-associated arsenic methylation, highlighting a possible biogeochemical link between methanogenesis and arsenic cycling in the studied aquifer. These findings contribute to understanding potential controls on MeAs occurrence in reducing groundwater and provide a basis for further investigations in comparable hydrogeological settings.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"301 ","pages":"126114"},"PeriodicalIF":12.8,"publicationDate":"2026-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147961721","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}

Antibiotics are of particular concern, as their persistence drives antimicrobial resistance, a growing threat to aquatic and human health. This study investigates the dual-function role of DOM leached from polyvinyl chloride -derived (PVC-DOM) in regulating the sequestration, transformation, and toxicity of seven representative antibiotics. Under dark conditions, PVC-DOM sequestered 28.53% of the initial antibiotic mass, nearly three times more than solid PVC particles (10.12%), through hydrogen bonding and π-π interactions. Under sunlight, PVC-DOM enhanced antibiotic photodegradation (up to 88.86%), with ³DOM* as the dominant contributor. Spectroscopy analysis revealed a staged, non-monotonic response: initial complexation, concurrent photochemical attack, and complex destabilization. Molecular characterization identified oxidized, condensed aromatic, and chlorinated compounds, enriched in carboxylated and oxygen-rich functional groups, as key drivers. Toxicity to Microcystis aeruginosa was more severe under sunlight (40.0% growth inhibition, 94.7% chlorophyll loss) than in darkness (71.1% growth inhibition, 84.1% chlorophyll loss), indicating that phototransformation products may amplify ecological risk. Non-target screening tentatively identified interactions products, with in silico predictions confirming their toxicity. These findings demonstrate that MP-DOM acts as a dynamic biogeochemical agent controlling micropollutant sequestration, photochemical transformation, and ecological risk, emphasizing the need to incorporate its reactivity into environmental risk assessments.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"301 ","pages":"126085"},"PeriodicalIF":12.8,"publicationDate":"2026-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147961727","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}

While aquaculture ecosystems are recognised as critical reservoirs for ARGs, the genomic architecture of MGEs that facilitate resistance dissemination in aquatic pathogens - particularly Aeromonas veronii (A. veronii) - remains underexplored. This study isolated a highly virulent, multidrug-resistant strain of A. veronii (Y6) from diseased largemouth bass, underscoring its potential dual threat to aquaculture and public health. Whole-genome sequencing revealed that strain Y6 harbours a chromosomal genomic island, GI22, containing a integron 1, which encodes 15 ARGs. Embedded within this island is a novel composite transposon, TnY6-1, which carries five of these ARGs and has the potential to facilitate horizontal gene transfer. Phylogenetic analysis revealed that strain Y6 clusters closely with human clinical isolates, underscoring its zoonotic potential. Comparative genomic analysis revealed that the resistance gene cassettes in integron 1 of strain Y6 are highly conserved across fish, human, and environmental isolates, suggesting the possibility of ARG transmission between different ecosystems. To quantify the environmental threat posed by TnY6-1, we applied a multidimensional risk assessment framework adapted from the PIPdb database. This marks the first classification of TnY6-1 as a Level IV high-risk MGE. These findings highlight the importance of implementing risk-based surveillance systems targeting hazardous MGEs in aquaculture to reduce the environmental-to-clinical spillover of antimicrobial resistance.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"301 ","pages":"126007"},"PeriodicalIF":12.8,"publicationDate":"2026-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147961739","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 reveal a ligand-directed mechanism by which sludge dissolved organic matter (DOM) regulates Pb(II) partitioning between mineral lattices and interfacial complexes. Increasing the hydrothermal temperature to 220 °C promoted the transformation of DOM toward oxygen-rich aromatic components, including highly oxidized carboxyl-rich alicyclic molecules and polyphenolic species, which preferentially bind Pb(II) through O-donor functional groups. FT-ICR MS combined with Pb L3-edge synchrotron XAFS indicates that Pb coordination shifts from Pb-O-P environments associated with Pb-phosphate precipitation/lattice incorporation to predominantly inner-sphere Pb-O-C bonding at the vivianite-solution interface. Density functional theory and molecular dynamics simulations further support that these O-ligand complexes provide both energetic stabilization and steric hindrance, thereby suppressing Pb(II) penetration into the vivianite lattice. Leveraging this interfacial confinement, we demonstrate a \"decoupled recovery\" approach in which surface-associated Pb is selectively removed by mild acidification (pH 3.5) while maintaining vivianite lattice integrity. This work links DOM molecular evolution to metal-mineral interfacial chemistry and suggests a feasible strategy to improve vivianite-based phosphorus recovery from Pb-impacted sludge streams.","PeriodicalId":443,"journal":{"name":"Water Research","volume":"301 ","pages":"126125"},"PeriodicalIF":12.8,"publicationDate":"2026-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147961691","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}
