In a prospective cohort of 377,694 UK Biobank participants without HF at baseline, we analyzed the associations between 241 environmental exposures and the risk of incident HF using an exposome-wide approach. Our analysis included exposome-wide association study (ExWAS) analyses via Cox regression, identification of key exposures using regularized Cox regression and LightGBM models, and pattern recognition with self-organizing maps and k-means clustering to assess cumulative effects. After adjusting for confounders and multiple testing, 54 exposures were significantly associated with HF risk in the ExWAS. Combining results from the regularization model and LightGBM, we identified protective factors like greater natural space and lower air pollution, and risk factors such as proximity to industrial facilities and high traffic density. Seven environmental patterns were identified, with the lowest HF risk linked to high natural environments and robust infrastructure. BMI was found to mediate these environmental links to HF.

Birds, as ecologically diverse and responsive taxa, are valuable indicators of environmental change and functional simplification. We examined how urbanization and pollution jointly influence the functional structure of avian communities across an urban-rural gradient in Sialkot District, a rapidly industrializing region of northeastern Pakistan. Using standardized point counts across 18 sites stratified by urban intensity and pollution levels, we quantified bird community composition and feeding guilds. We applied multidimensional indices of functional diversity (FRic, FEve, FDis, RaoQ) and ordination methods to assess trait-based filtering. Functional richness and divergence contracted markedly with increasing pollution and urbanization. Functionally specialized guilds particularly insectivores, piscivores, and carnivores were absent from the most polluted urban sites, which were dominated by ecological generalists such as omnivores and scavengers. Trait dissimilarity and redundancy declined sharply with pollution, and ordination revealed clear guild turnover along the pollution gradient, indicating homogenization of trophic roles. Functional evenness and dispersion showed weaker responses, suggesting selective persistence of a few tolerant guilds in urban cores. Feeding guild richness also declined with pollution, reflecting a strong loss of trophic diversity under anthropogenic stress. These findings provide rare empirical evidence from South Asia linking environmental contamination to multidimensional losses of avian functional diversity. By integrating trait-based metrics with ecological gradients, this study highlights the need to incorporate functional indicators into conservation planning, particularly in rapidly urbanizing regions where ecological data remain limited.</p>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":" ","pages":"123029"},"PeriodicalIF":7.7,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145249143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

However, whether the influence of nutrient-driven dissolved organic matter (DOM) composition on OC dynamics is convergent or divergent across aquatic systems remains unclear. This study selected 124 sediment sites from rivers, reservoirs, and offshore areas to investigate the relationships between DOM components, OC fractions, and environmental parameters. OC pools from different aquatic regions have similar distributions, with particulate OC (POC) and mineral-associated OC (MAOC) accounting for 90% of the total OC pool. DOM's sources and compositions differ in those aquatic ecosystems. In rivers and reservoirs, DOM mainly comes from allochthonous inputs, demonstrating a high degree of humification and a large molecular weight. Offshore DOM is characterized by a smaller molecular weight and lower humification; it receives inputs from both allochthonous and autochthonous sources, with the latter predominating. DOM composition (66.81%) and environmental parameters (33.19%) jointly regulate OC pool dynamics across aquatic regions, with DOM composition being the key influencing factor. Specifically, available phosphorus, total nitrogen, nitrate nitrogen, and ammonium nitrogen affect autochthonous DOM, which in turn influences MAOC distribution. By contrast, allochthonous DOM is only influenced by phosphorus forms and contributes to increased POC. Compared with allochthonous DOM, autochthonous DOM has a greater effect on sediment OC. These findings emphasize the importance of \"multisource\" carbon management for sustaining OC sinks in aquatic environments and providing a theoretical framework for optimizing carbon-neutral development.</p>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":" ","pages":"123032"},"PeriodicalIF":7.7,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145249158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Impoundment structures such as dams alter fluvial hydro-sedimentary conditions, facilitating microplastic settlement and retention within reservoirs. However, the vertical transport mechanisms of positively buoyant microplastics in such systems remain poorly quantified, particularly regarding how hydro-sedimentary dynamics (e.g., turbulence and suspended sediments) drive their downward migration. Here, we provide the first experimental quantification of vertical transport processes for positively buoyant microplastics under varying turbulent shear rates (G) and suspended sediment concentrations (SSCs) in the Three Gorges Reservoir (TGR). Our experiments revealed that under typical TGR hydro-sedimentary conditions, two key mechanisms governed vertical transport: (1) increasing turbulent shear forces facilitated microplastic penetration below the surface layer by overcoming buoyancy through fluid-particle interactions; (2) SSC-mediated heteroaggregation dominated their transport to deeper layers. A critical shear rate threshold was identified (G = 19.94 s^-1), at which both aggregate size and settling efficiency peaked-markedly enhancing microplastic accumulation in deep-bottom layers. The fractal dimension of aggregates exerted a greater influence on settling velocity than aggregate size alone: elevated shear rates promoted denser aggregate structures, accelerating settling; conversely, higher SSCs induced structural loosening during aggregate expansion, reducing settling rates. These findings clarify the pivotal role of hydro-sedimentary dynamics in regulating the vertical distribution of microplastics, providing a mechanistic basis for why the TGR acts as a \"settling hotspot\" for microplastics. More broadly, the results advance our understanding of how reservoirs trap buoyant microplastics, with implications for assessing microplastic fate in freshwater impoundments globally.</p>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":" ","pages":"123034"},"PeriodicalIF":7.7,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145249170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Therefore, it is essential to clarify the effects of modified biochar on soil carbon dioxide (CO₂), as well as methane (CH₄) and nitrous oxide (N₂O) emissions. Transient electromagnetic pulse (TEMP) modification, as a physical modification approach, circumvents the secondary pollution risks associated with traditional chemical modification and holds potential as an innovative strategy for soil carbon sequestration. However, the impact of TEMP-modified biochar on CO₂, CH₄, and N₂O emissions remains unclear. This study investigated the effects of TEMP-modified biochar, characterized by different particle sizes, on CO₂, CH₄, and N₂O emissions in subtropical grassland soils. Results demonstrated that TEMP modification increased biochar's specific surface area and enhanced its pore structure, while decreasing the proportion of C-O-C functional groups in biochar. Notably, TEMP-modified biochar with a particle size of 0.5-1 mm exhibited the strongest inhibitory effect, reducing CO₂, CH₄, and N₂O emissions by 7.47 %, 83.44 %, and 25.27 %, respectively, compared to unmodified biochar. By contrast, TEMP-modified biochar with particle sizes of <0.154 mm and 1-2 mm did not significantly affect these emissions. Multiple regression and structural equation modeling were employed to quantify the pathways through which modified biochar influences CO₂, CH₄, and N₂O emissions. We found that the physical protection effect of TEMP-modified biochar suppresses CO₂ emissions. The enhanced porosity of modified biochar promotes its adsorption capacity for CH₄ and N₂O. Additionally, TEMP-modified biochar increased the content of dissolved organic carbon and available phosphorus, which, in turn, inhibit denitrifying microbes, thereby reducing N₂O emissions. These findings suggest that TEMP technology enhances carbon sequestration in grassland soils by stabilizing biochar and reducing CO₂, CH₄, and N₂O emissions.</p>","PeriodicalId":312,"journal":{"name":"Environmental Research","volume":" ","pages":"123009"},"PeriodicalIF":7.7,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
