Two configurations were compared: (1) indirect treatment using purifiers with electrochemically regenerated AC and (2) direct treatment using electrochemical cells that combine adsorption, electro-absorption, and in situ AC regeneration. A comprehensive Life Cycle Assessment (LCA) was conducted, encompassing human toxicity, global warming potential, freshwater ecotoxicity, resource use, and a Life Cycle Costing (LCCA). These systems reduced cancer-related human toxicity impacts by 90–93%, offering a substantially safer alternative to untreated indoor air or conventional ventilation approaches. The integrated system (Case 2) consistently achieved the lowest environmental burdens, showing around 30% reductions across all evaluated categories. The impacts obtained were 3.9·10⁻⁷ CFC11 eq for ozone depletion, 2 L of water consumption, 52.1 PAF·m³·day in freshwater ecotoxicity, and 26.8 g CO₂ eq for global warming per m³ of treated air. Using renewable energy decreased toxicity impacts by over 70% compared to conventional grids, and up to 97.5% compared to untreated air. On-site AC regeneration reduced material use by up to 87% and environmental footprint by 73%. The monetized cost analysis confirmed the economic viability of the system, with values as low as € 0.11–0.13 per m³ of treated air, supporting this technology as a competitive and sustainable solution for indoor VOC mitigation.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"1018 ","pages":"Article 181524"},"PeriodicalIF":8.0,"publicationDate":"2026-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146163346","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 totality of environmental awareness, i.e., environmental attitudes, concern, knowledge and behavioural intention in relation to pro-environmental behaviour. It further interrogated the moderating role of perceived policy effectiveness between environmental awareness and pro-environmental behaviour. Eight hypotheses were investigated, labelled H1 to H8, using Structural Equation Modelling and Hierarchical Regression Analysis. The findings reveal a complex interplay and sometimes counterintuitive relationship between the environmental constructs, i.e., environmental concern, knowledge, attitudes, and pro-environmental behaviour, highlighting both the potential and limitations of awareness-raising initiatives in driving behavioural change. We conclude that among the encroachers investigated, H1, H2 and H7 are supported, i.e., environmental concern and behavioural intentions were important drivers of pro-environmental behaviour, while also pointing that H4 and H6 were not supported, indicating environmental attitude and knowledge do not directly predict pro-environmental behaviour. We further conclude and suggest that perceived policy effectiveness of encroachers (H8) is contingent on effective policy enforcement, without which pro-environmental behaviour will not be triggered among these stakeholders.

This study examines the metabolic and physiological responses of wheat (<em>Triticum aestivum</em>) and barley (<em>Hordeum vulgare</em>) to the allelochemicals umbelliferone (UMB) and scopoletin (SCOP), evaluating their potential as biopesticides. Despite their demonstrated bioactivity, commercialization is hindered by limited understanding of their mechanisms of action, impact on non-target organisms, and cost-effectiveness. To address these challenges, a metabolomic approach was used to assess the effects of UMB and SCOP on important worldwide cereal crops and identify key metabolites involved in their responses. A metabolomic approach was used to compare their effects with conventional pesticides: 2,4-dichlorophenoxyacetic acid (2,4-D) and tebuconazole (1-(4-chlorophenyl)-4,4-dimethyl-3-(1H-1,2,4-triazol-1-ylmethyl)pentan-3-ol, TBC). Non-target LC-ESI-MS/MS and LC-Full-MS/ddMS² analyses identified significant metabolite changes, while chemometric tools ensured robust data interpretation, which were validated by cross-validation and permutation testing, confirming the stability and predictive accuracy of the results. The findings showed that UMB minimally disrupts plant metabolism while activating key defense pathways, as evidenced by increased levels of fatty acids, auxins, and phytoalexins. In contrast, SCOP induced metabolic changes similar to those of the synthetic fungicide TBC, suggesting its potential as a natural fungicide alternative. These outcomes establish a robust framework for assessing the broader applicability of natural biopesticides, offering innovative and environmentally benign alternatives to synthetic pesticides while addressing pressing challenges in food security and environmental sustainability.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"1018 ","pages":"Article 181511"},"PeriodicalIF":8.0,"publicationDate":"2026-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146163311","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}

Child blood lead levels (BLLs) were estimated using the U.S. Environmental Protection Agency's Integrated Exposure Uptake Biokinetic (IEUBK) model. Regression models linked predictors to Pb in each medium and IEUBK-estimated BLLs.

Notably, homes previously remediated for Pb in IN had 3× higher soil Pb and 2× higher modeled blood Pb than non-remediated homes, underscoring persistent exposure risks despite remediation efforts. Housing age remained a significant predictor across states, with newer homes associated with reductions in Pb concentrations. In IN, a higher percentage of Black residents was associated with higher water Pb, while in NC, poverty level and water source were stronger predictors. Private well use was linked to 4.4× higher water Pb concentrations compared with municipal systems. Population intervention modeling suggested that children's BLLs would be substantially higher today if housing construction and Pb use mirrored earlier eras, underscoring the public health benefit of Pb bans on paint and restrictions in plumbing.

This study focuses on one such hotspot: the tropical Andes (comprising Colombia, Ecuador, Peru, and Bolivia), using glyphosate as a model for analysis, as it is one of the most widely used and controversial herbicides worldwide. Concerns about its use are debated and include potential effects on human health, biodiversity loss, negative environmental impacts, and the emergence of resistant weeds. Our objective was to systematically document and analyze the available scientific literature, quality assurance parameters for chemical measurements, and the characteristics of commercial products. Of 166 articles reviewed since 1985, less than 20% addressed glyphosate measurement. All techniques described seemed appropriate to the objectives of each study. However, 84.4% of studies applied at least one quality assurance parameter; a comprehensive assessment of all of them was not evident. Furthermore, inconsistencies were identified in the categorization of commercial products with the same formulation and concentration, which presented different acute toxicity labels under Andean Community regulations. These discrepancies, along with technological limitations, a lack of regional standardization, and a paucity of information, hamper these countries' ability to mitigate the impacts of pesticide use, such as glyphosate.</div></div>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":"1018 ","pages":"Article 181522"},"PeriodicalIF":8.0,"publicationDate":"2026-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146172886","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}
