To enhance this process, magnetic biochars are frequently employed as conductive additives to promote direct interspecies electron transfer (DIET) among syntrophic microorganisms. However, the fundamental mechanisms regarding how iron species leached from these materials influence iron transformation and electron flux remain poorly understood. Here we show that the leaching of iron species from magnetic biochar establishes a stable Fe(III)/Fe(II) redox cycle that accelerates the hydrolysis, acidogenesis, and methanogenesis of waste-activated sludge. We find that cumulative methane production increases by 17 % as leached Fe(III) facilitates dissimilatory iron reduction, followed by secondary mineralization into high-crystalline iron species. This process selectively enriches electroactive taxa, including <em>Geobacter</em> and <em>Methanothrix</em>, and transitioned the dominant electron transfer mechanism from cytochrome c-dependent pathways to a Fe(III)/Fe(II) redox-driven DIET. These mechanisms advance our understanding of conductive material-mediated AD, offering strategies to optimize energy recovery from waste-activated sludge and support sustainable sludge management in wastewater treatment.</div></div>","PeriodicalId":34434,"journal":{"name":"Environmental Science and Ecotechnology","volume":"29 ","pages":"Article 100660"},"PeriodicalIF":14.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146078664","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 the adverse outcome pathway (AOP) framework provides a mechanistic scaffold for organizing toxicity knowledge, it is currently limited by a focus on linear pathways and a bias toward well-studied endpoints. Conversely, the exposome paradigm captures broad environmental stressors but often lacks the mechanistic depth required for causal interpretation. A fundamental challenge remains in developing integrative paradigms that can systematically bridge these multi-scale datasets to decode complex, chemical-induced diseases. Here we show that AOP-ExpoVis, an integrative computational platform, synergizes exposome-disease networks with AOP ontologies to prioritize pathogenic mechanisms through a weighted phenotype-disease scoring algorithm. By integrating chemical, gene, phenotype, and disease associations, the platform identifies key phenotypes and maps them to curated pathways to generate testable mechanistic hypotheses. Validation across three distinct case studies involving 2,2′,4,4′-tetrabromodiphenyl ether (BDE-47), arsenic, and perfluoroalkyl substances (PFAS) demonstrated that AOP-ExpoVis accurately identifies both conserved and chemical-specific toxic pathways, such as aryl hydrocarbon receptor activation and lipid metabolism disruption. AOP-ExpoVis provides an open-source tool for rapid mechanistic inference that overcomes the limitations of traditional, single-pathway frameworks. This work advances predictive toxicology by enabling the systematic prioritization of chemical hazards and the refinement of regulatory risk assessment in a data-rich environment.</div></div>","PeriodicalId":34434,"journal":{"name":"Environmental Science and Ecotechnology","volume":"29 ","pages":"Article 100663"},"PeriodicalIF":14.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146078667","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}

Our results reveal that disruptions propagate through alternating horizontal–vertical and direct–indirect pathways, with risk concentrating at the mining stage but accumulating predominantly in refining–manufacturing bridges. These cascades yield abrupt nonlinear failures and an avalanche network four times denser than the underlying physical supply chain. Nations with low systemic fragility but high exposure rate—such as Indonesia, South Africa, and Mexico—are particularly susceptible to common random disruptions and lack resilience or effective response.

While the neurotoxic effects of high-dose ephedrine exposure are documented in humans and other mammals, its impact on aquatic vertebrates at environmentally realistic concentrations remains poorly understood. Determining how these persistent residues affect neural development and physiological homeostasis is critical for evaluating ecological risks to aquatic life. Here we show that chronic, low-dose ephedrine exposure impairs neurodevelopment in adult zebrafish by simultaneously disrupting synaptogenesis architecture and neurotransmitter balance. Integrated transcriptomic and histopathological analyses reveal that ephedrine targets the synaptogenesis signaling pathway, resulting in reduced presynaptic vesicles and structural abnormalities in the postsynaptic density. Computational docking and biochemical assays further demonstrate that ephedrine engages the vesicular acetylcholine transporter and tyrosine hydroxylase with high affinity, triggering excitotoxic cascades and biphasic neurochemical dysregulation that manifest as anxiety-like phenotypes and cognitive impairments.

Citizen science has revolutionized ecological monitoring in other domains by enabling scalable, participatory data collection, but its application to wetland restoration has been largely overlooked. In this Perspective, we assess 120 restoration project sites worldwide and find that citizen science is currently integrated into fewer than 20 % of projects even in high-activity regions like Europe, leaving significant social and geographic potential untapped. We find that recent advances in affordable remote sensing, miniaturized sensors, and mobile platforms—supported by rigorous data-validation frameworks—are now overcoming historical constraints regarding data reliability and spatial continuity. These technological shifts, when coupled with emerging institutional recognition, allow citizen-generated data to serve as a scalable, cost-effective infrastructure for monitoring ecological change over meaningful timescales.

In China, rapid urbanization has driven a massive expansion of the construction sector, with emissions arising from building material production, onsite operations, upstream supply chains, and operational energy use in buildings. Although end-of-pipe controls have markedly lowered pollutant emissions since 2013, further reductions are increasingly costly, and air quality and climate policies remain poorly integrated. The full lifecycle health burden imposed by construction-related air pollution, its temporal evolution, and the scope for health co-benefits from decarbonization—particularly across urban and rural divides—have been incompletely characterized. Here we integrate a detailed construction emission inventory, input–output analysis, inverse atmospheric modelling, and health impact assessment to quantify these impacts in China from 2000 to 2019. We show that construction-related emissions, including upstream power and industrial sources, caused 1.10 million (95% CI: 0.83–1.37 million) premature deaths in 2019, accounting for 50% (95% CI: 38–62%) of national ambient PM_2.5-attributed mortality. Health burdens evolved through three phases: rapid increase with 130% CO₂ growth during intense urbanization (2000–2008), decoupling via pollution controls that averted 0.36 million deaths despite rising CO₂ (2008–2015), and synergistic declines from energy-mix optimization and technology upgrades (2015–2019). Urban mortality stems predominantly from upstream industrial emissions, whereas rural mortality is driven by residential heating; decarbonizing power and heavy industry offers the largest urban co-benefits, while rural clean-electricity heating requires concurrent power-sector greening to prevent CO₂ penalties.

These observations provide <em>in situ</em> evidence associating benthic algal seed stocks with surface bloom initiation, revealing that the origin and spatial heterogeneity of such events arise from rainfall-driven disturbances at the sediment–water interface.
