In this work, solid superacid modified CeO₂ with highly dispersed acid-base sites was constructed, achieving the capture of acidic/basic poisons. Moreover, the designed catalyst retained active sites for the adsorption and activation of NH₃ after poisoning. The sulfated ZrO₂/CeO₂ exhibited 2.0, 1.1, 2.3, 1.2, and 2.6-fold increase of NO_<em>x</em> conversion than commercial V₂O₅-WO₃/TiO₂ when Pb, As, Zn, K, and Cd loading. The highly dispersed monodentate sulfate species on the catalyst surface provided abundant acid sites for the capture of basic poisons (e.g., Cd, Pb, K, Zn) and NH₃ adsorption. The basic CeO₂ doped with Zr captured acidic poisons (e.g., As) and promoted the activation of NH₃ due to the high capacity of Ce³⁺ and oxygen vacancies. Spectroscopic characterization revealed that the highly dispersed acid-base sites along with more Ce³⁺ species on the catalyst surface facilitated the adsorption and activation of NH₃, crucial for the formation of the reaction intermediate NH₂NO. This work may provide an approach to develop efficient SCR catalysts with superior resistance to poisons and reduce the generation of waste catalysts.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"111 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745545","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}

Herein, we present an AIE-active Janus air filter membrane (AIE-HAFM) that features water-dissolvable micro-nano porous network architecture and aggregation-induced emission (AIE) activity constructed by the asymmetrical surface modification with an amphiphilic AIE photosensitizer (MeOTTVP). The all-round AIE-HAFM can not only provide low pressure drop and high interception efficiency for bioaerosol sampling but also perfectly inherit the AIE functions of MeOTTVP, which allows for intensive near-infrared (NIR) emission and efficient production of reactive oxygen species. The airborne pathogens can be effectively captured, collected, transferred, and released by AIE-HAFM for subsequent quantitative detection with colony counting and ATP bioluminescence, as well as stained by the incorporated MeOTTVP for NIR fluorescence imaging-guided visual detection. Meanwhile, AIE-HAFM enables on-demand and surface-dependent photodynamic effects for reliable bacterial eradication under white light irradiation due to the surface-concentrated MeOTTVP, consequently achieving the smart prevention and control of bioaerosols both in the simulated and real-world bioaerosol environment.

However, the accumulation of byproducts such as NO₂^-, N₂O, and NH₄⁺, poses a significant challenge to effluent quality and climate adaptation. This study hypothesized that introducing anaerobic ammonium oxidation bacteria (anammox) to BED could alleviate this issue through synergy: a) anammox can utilize NH₄⁺ and NO₂^- from BED without producing N₂O, as seen in canonical denitrification, and b) BED can recycle the NO₃^- from the anammox anabolic pathway. Results showed that Anammox_BED reduced NO₂^- accumulation by two-thirds, lowered the relative abundance of N₂O by 80%, and eliminated NO. Metagenomic analysis revealed that the anammox species Ca. Brocadia sapporoensis tripled in abundance in the bulk sludge. <em>Pseudomonas stutzeri</em> and <em>Bosea robiniae</em>, species capable of reducing nitrate via extracellular electron transfer (EET) and supplying NO₂^- to anammox, halved in relative abundance, while the abundance of <em>Stenotrophomonas acidaminiphila</em>, a non-EET, ammonia assimilation species, doubled following anammox introduction. Metatranscriptomic analysis suggested upregulation of denitrification-related functional genes in Anammox_BED biofilm and survival- and motility- related genes in the bulk sludge possibly due to insufficient substrate. Overall, BED-Anammox successfully diverted the rate-limiting EET nitrite reduction towards anammox-driven nitrite utilization thereby mitigating the generation of unwanted intermediates.<h3>Environmental Implication</h3>Bioelectrochemical denitrification (BED) often results in the accumulation of intermediate products such as nitrite, N₂O, and NO, which is harmful to microbial activity and has significant climate change impacts. This study demonstrates that integrating anammox bacteria into BED effectively reduces the accumulation of nitrite and eliminates the generation of NO through a metabolic synergy. The BED-anammox system has the potential of being a sustainable nitrate treatment technology.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"26 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745548","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}

This study explored the combined ultraviolet and peracetic acid (UV/PAA) process as a novel strategy for BW disinfection. The UV/PAA process effectively inactivated <em>Fecal coliform</em> (1.372 × 10^{-5<!-- -->}s^-2) in real BW, despite presence of turbidity, suspended solids, and organic matter, which could hinder disinfection. The highly electrophilic PAA and acetoxy(peroxy) radicals were identified as crucial contributors to bacterial inactivation. Biochemical analysis and Density Functional Theory calculations revealed that the system primarily operates through selective intracellular biomolecular oxidation. Electrophilic species preferentially oxidized amino acids with highly local nucleophilicity index, particularly those containing sulfur or nitrogen moieties. This selective oxidation caused protein denaturation, inducing cells into a viable but non-culturable (VBNC) state. Meanwhile, the membrane integrity and metabolic activity was preserved, while oxidative stress and DNA disruption effectively limited bacterial regrowth, proving that this process selectively damages intracellular biomolecules, such as amino acids and DNA. Additionally, the process significantly reduced the abundance of gut microbiota and other pathogens in real BW, highlighting its broad-spectrum antimicrobial efficacy. The UV/PAA process represented a sustainable and eco-friendly advanced disinfection solution for BW treatment.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"15 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143737107","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}

In this study, adult zebrafish were exposed to 5 and 50<!-- --> <!-- -->nM 2,4-DTBP for 60 days. Reduction in cumulative egg production was observed after 45 days of exposure. Gonadal maturation was also delayed in both female and male zebrafish following 2,4-DTBP exposure. The impaired fecundity was attributed to an imbalance of 17β-estradiol/testosterone ratio (E2/T) and altered transcripts involved in the hypothalamic-pituitary-gonadal (HPG) axis. Upon exposure, aromatase (CYP19) and E2 levels were significantly decreased in females, but were increased in males. Additionally, molecular docking revealed potential binding of 2,4-DTBP to estrogen receptors and CYP19, highlighting molecular initiating events that may interfere with steroid hormone synthesis. We also showed that 2,4-DTBP can be transferred to offspring, affecting their development and compromising immunity. The expression of triiodothyronine (T3) and hatching-related genes (<em>esr2α</em>, <em>esr2β</em>, and <em>zhe2</em>) were altered, suggesting that parental exposure to 2,4-DTBP resulted in multigenerational toxicity in F1 larvae.

However, As activity is highly variable during the rice reproductive cycle, there is still a lack of approach to accurately predict and to the phytoavailability of As due to the paddy soil heterogeneity and complexity.

Protective Action Guides aid decision makers in enacting public safety measures. This paper explores how areas impacted by radionuclides in excess of derived response levels change due to rain. Two Storm Water Management Models (SWMM) were modified to incorporate overland flow and used to study simulated trends in transport from a hypothetical radiological plume. This modeling suggests that the areas that require evacuation/relocation using pre-calculated response dose limits were reduced by 36-62% due to washoff during a 2-year return 24-hour design storm. The study also found variable amounts of radionuclide removal and endpoints in each city depending on land use and infrastructure capacity. One city had 1.3 times more washoff and 2.3 times more discharge to the receiving water (by total Bq). The greater simulated washoff was attributed to higher impervious land use types in the blast area. The lower simulated discharge to the receiving waters in the other city was due to more internal storage in the model and more losses to street flooding. The study also identified need for precalculated response levels for stormwater specific exposure scenarios to expedite the use of SWMM after an emergency.<h3>Environmental Implication</h3>This paper focuses on the environmental transport of Cesium-137 in urban stormwater. Cesium-137 is considered a hazardous material because it is a high gamma emitter, is highly soluble, persistent in the environment, and bioaccumulated. Additionally, it can easily spread through surface and subsurface environments making it particularly concerning for human and environmental health. This work addresses the environmental problem by using stormwater modeling in two different locations to understand how differences in landuse impact transport of Cesium-137 in urban areas and intersecting these results with protective action guidelines for exposure to Cesium-137.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"27 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745547","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}

An in-situ glycine leaching regeneration method was developed to restore the activity of Tl-poisoned V₂O₅-WO₃/TiO₂ catalysts. The specific coordination ability of glycine facilitates the selective removal of Tl. The coordination mode between glycine and Tl⁺ is modulated by introducing H⁺, significantly enhancing the coordination capacity for Tl⁺, thereby facilitating the deep removal of Tl, with a leaching efficiency of 90.19%. Moreover, glycine effectively reconstructs the vanadium active sites, and substantially restores the redox properties and surface acidity of the catalysts. The regenerated catalyst exhibits catalytic activity comparable to that of the fresh catalyst. Additionally, Tl⁺ leached by glycine is successfully recovered as TlCl.
