Nevertheless, the reported COFs intrinsically lack the capacity to harvest infrared light, which results in inferior photothermal conversion efficiency and thereby retards the water evaporation rate. Here we report a class of Cl-functionalized COFs with ultra-broadband absorption spanning 200–1,500 nm and strong non-radiative relaxation capacity for enhancing SDWE performance. The synthesized TTB-pPA COFs (where TTB is 2,4,6-trichloro-1,3,5-trialdehyde benzene and pPA is p-phenylenediamine) exhibit a notable temperature rise to 125.3 °C within 60 s under 1-sun illumination, superior to that of COFs without Cl atom (60.7 °C). The SDWE device was constructed by using TTB-pPA COFs as photothermal conversion layer, showing an elevated water evaporation rate of 7.62 kg m−2 h−1, which significantly outperform previously reported water evaporation device. Furthermore, the custom-developed water evaporation device demonstrates long-term stability of 60 days under natural light conditions, together with the pure water production (impurity content <0.1%) of 30–45 l m−2 d−1, which can meet the drinking water needs of 12–18 people. Overall, this work emphasizes the significance of designing COFs with a broad light absorption range and strong non-radiative electron decay capability in enhancing solar-powered seawater desalination capability. This study introduces chlorine-functionalized covalent organic frameworks capable of absorbing a broad range of sunlight and efficiently converting it to heat, dramatically improving solar-driven water evaporation and enabling stable, high-purity freshwater production for practical desalination.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 9","pages":"1157-1165"},"PeriodicalIF":30.7,"publicationDate":"2026-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148981556","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, whether these efforts have succeeded remains unclear. Here we compile 1,624 global estimates from 65 studies published between 1974 and 2025 and evaluate them across 360 analytical pathways, spanning a comprehensive range of plausible statistical designs. Our results indicate that uncertainty in global irrigation water withdrawals has not declined: only 17% of pathways show any reduction over time, falling to 10% once projections to 2100 are excluded. The most common outcome is an increase in uncertainty (40% of pathways), followed by an unstable trend (34%). Progress may therefore require the field to renounce the goal of reducing uncertainty and instead double down on what it has historically done best: expanding it, until uncertainty reaches the boundary of what current knowledge of global irrigation cannot exclude. Accurate quantification of global irrigation water withdrawals is hindered by persistent uncertainty despite decades of model refinement. The evaluation of estimates across a wide range of analytical approaches revealed little evidence of declining uncertainty, challenging the assumption that progressively improved models necessarily yield more certain estimates.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 10","pages":"1343-1354"},"PeriodicalIF":30.7,"publicationDate":"2026-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s44221-026-00710-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149190073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current ecological risk assessment frameworks face challenges in addressing the diversity of physiological and biochemical characteristics of aquatic organisms. Here we pioneer the intelligent high-throughput multi-species physiologically based toxicokinetic (HM-PBTK) model by developing AI-driven models for multi-species physiological and biochemical parameters. The HM-PBTK model precisely quantifies tissue-specific internal exposure and predicts in vivo toxicity for neutral and ionizable chemicals across 151 freshwater and marine fish species. In an oestrogenic-effect case study, 85% of toxicity predictions were within fivefold of the corresponding observations. We further developed a user-friendly platform enabling comprehensive ‘exposure–toxicity’ predictions for chemicals by simply setting up exposure scenarios. Our study helps to explore the risks of chemical pollution to aquatic ecosystem, ultimately contributing to the protection of aquatic biodiversity. The ecological risks posed by chemical pollution are difficult to evaluate across diverse aquatic species using existing assessment frameworks. An AI-driven multi-species modelling framework and prediction platform can quantify chemical exposure and toxicity in freshwater and marine fish alike.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 10","pages":"1282-1295"},"PeriodicalIF":30.7,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149190071","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}

Here we develop a globally scalable, seasonally resolved framework that classifies catchments according to the complexity of how rainfall is converted into runoff across events, yielding three functional types: simple, intermediate and complex. Applied to over 80,000 gauged and ungauged catchments, it reveals that functional complexity is the global norm: catchments draining 87% of the evaluated ungauged land area are classified as complex in the dormant season, with the number of complex catchments increasing by 63% in the growing season. Africa and much of Asia (except Japan) remain predominantly complex year round, Europe reaches 94% complex in the growing season, the US Pacific Northwest and Canada’s British Columbia retain simple clusters, and southeastern South America and southeastern Australia show notable transitions from complex to intermediate, demonstrating that catchment functional type is not fixed. Greater urban and agricultural land cover, together with less persistent rainfall, are associated with greater functional complexity. These findings provide a blueprint for prioritizing streamflow gauging in under-represented complex catchments and for guiding model structural selection, transferability and prediction in ungauged catchments, ensuring that models are neither simpler than necessary nor more complex than required. This study presents a globally scalable, seasonally resolved classification of gauged and ungauged catchments into three functional rainfall–runoff types (simple, intermediate and complex), revealing that functional complexity is the norm across most of the world’s rain-dominated streams and rivers and providing a framework to guide streamflow gauging network prioritization and hydrologic model structural design.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 10","pages":"1271-1281"},"PeriodicalIF":30.7,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149190079","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}

Here we report a localized potential well engineering strategy that facilitates the directional injection of photogenerated electrons towards the atomic active sites, which enhance photocatalytic uranium extraction from natural seawater. The as-made industrial-level TAPT–DFBP covalent organic frameworks (COFs) (TAPT: 1,3,5-tris-(4-aminophenyl)triazine, DFBP: 5,5′-diformyl-2,2′-bipyridine) exhibits an average uranium extraction rate of 7.25 mg g−1 d−1, which is higher than those of reported active materials. The as-fabricated large-area TAPT–DFBP COF film (150 cm × 250 cm) possesses a high photocatalytic uranium extraction capacity of 8.9 mg g−1 from real marine environments. Mechanistic investigations reveal that the construction of localized potential wells within COFs induce multiple electron transport paths towards atomic active sites, thereby facilitating the separation of photogenerated electron–hole pairs and enhancing the photocatalytic uranium extraction from natural seawater. Enhancing charge separation and directing photogenerated electrons to active sites remain key challenges in photocatalytic uranium extraction.

Here we investigated a wastewater treatment plant–receiving river continuum by integrating 159 ECs, cytotoxicity, GHGs, risk prioritization, multi-omics and controlled microcosms. Although treatment removed 82.21% of ECs, effluent increased downstream ECs (53.21%), cytotoxicity (44.15%) and CO2 equivalents (11.31%). Moreover, defence functions (efflux pumps, biofilm formation and P450 detoxification) declined by 52.34–57.98%, whereas GHG-linked carbon/nitrogen genes were 1.94–33.67 times more abundant than upstream levels, beyond what could be explained by source mixing alone. Semi-continuous microcosms comparing EC-rich effluent, upstream and EC-depleted effluent showed that EC stress suppressed defence functions while activating respiration, fermentation and carbon/nitrogen transformations. Enzyme and metabolite analyses revealed EC-induced oxidative stress and transient energy depletion, followed by recovery of acetyl-CoA content, citrate synthase activity and adenosine triphosphate availability, indicating a shift from defence to energy maintenance, thereby promoting GHG generation under long-term downstream EC exposure. Using multi-omics and microcosm analyses, this study shows that mixtures of emerging contaminants suppress microbial defence functions while redirecting metabolism towards energy production, enhancing greenhouse gas generation.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"4 10","pages":"1296-1306"},"PeriodicalIF":30.7,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149190080","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}
