The study assessed the formation of dichloroacetaldehyde (DCAL) and trichloroacetaldehyde (TCAL) from model algal organic matters (Gly-Ala and Leu-Ala), and clarified the transformation mechanisms from the insight of quantum chemical computations.

The initial pH of pre-ozonation was observed to be an important factor that influenced the HALs formation potential. The alkaline conditions promoted the formation of HALs, while acidic conditions have an inhibitory effect. Furthermore, the ultra-performance liquid chromatography high-resolution mass spectrometry (UPLC-HRMS) was applied to identify the transformation products of the pre-ozonation-chlorination process. Combined with quantum chemical computations, the transformation pathways of HALs were proposed. It was found that pre-ozonation promotes the formation of acetaldehyde, an intermediate during the formation of HALs. The initial pH plays an important role in the production of HALs, which influenced the reaction pathways and affected OH• formation. This study provides an in-depth analysis of the reaction mechanism and offers new theoretical insights for mitigating, controlling, and managing the risks associated with HALs.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"22 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143083641","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}

Moreover, GLA exposure resulted in a significant increase in malondialdehyde content, which subsequently activated the antioxidant system and detoxification system, and the related enzyme activities and gene expression levels were significantly increased. In addition, the RNA-Seq analysis showed that the toxic effects of GLA exposure on juvenile crabs may mainly involve physiological pathways such as energy metabolism, protein synthesis and nervous system function.

Metal hyper-resistance in acidophilic microorganisms remains an underexplored intriguing phenomenon. Using a multi-level approach, we provide the first data on extreme zinc resistance mechanisms in <em>Sulfobacillus thermotolerans</em>, recognized as one of the most metal-resistant organisms known. Under high zinc levels, <em>Sb. thermotolerans</em> cells exhibited efficient zinc sorption and low intracellular accumulation. Remarkably, mechanisms involved the upregulation of stress response and metabolic pathway proteins, including different GroEL chaperonin forms. Moreover, overexpression of the <em>Sb. thermotolerans St</em>GroEL chaperonin in <em>Escherichia coli</em> enhanced its growth and zinc resistance under zinc stress. 3D structure modeling and ion binding site prediction in <em>St</em>GroEL revealed 46 amino acid residues potentially involved in zinc docking. Thriving in natural and engineered environments, such as sulfide mines, mine waste disposal sites, and AMD, <em>Sb. thermotolerans</em> is a key member of acidophilic microbial communities used in commercial biotechnologies for sulfidic raw material processing.

However, concerns arise due to residual byproducts such as catalysts and reactive oxygen species (ROS) in the treated effluents, potentially impacting crop and human health. The current work explored the impacts of AOPs-treated effluents on crop physiological traits and the potential microbial and chemical health risks associated with the consumption of such crops. Lettuce and Swiss chard were irrigated using secondary municipal wastewater effluents treated with TiO₂-photocatalysis (Ti-TE), UV (UV-TE), ozone (O-TE) and municipal tap water (MTW) as control. The effect of the different irrigation streams on crop growth was evaluated. The results revealed significant phytotoxic stress on the examined crops, with Ti-TE showing more pronounced effects than UV-TE and O-TE. Notably, TiO₂ deposition in stomata and leaf coverage led to significant chlorophyll fluorescence and gas exchange stresses on the crops. Ti-TE caused the highest percentage of electrolyte leakage in Swiss chard (34.22%) and lettuce (25.29%), followed by O-TE (19.07% in Swiss chard and 20.20% in lettuce) and UV-TE (12.90% in Swiss chard) and 19.57% in lettuce). Interestingly, Swiss chard exhibited higher tolerance to phytotoxicity stress from Ti-TE, UV-TE, and O-TE than lettuce. No pathogens were detected on the crop leaves, with <em>E. coli</em> reading &lt; 1 MPN and no faecal coliform reaction observed. However, the levels of titanium found on the edible leaves (Swiss chard: 2.7, lettuce: 1.46, g kg^-1 dry-leaf weights) indicated potential health risks associated with consuming Ti-TE-irrigated crops. Conversely, O-TE and UV-TE demonstrated a promising approach to maintaining environmental integrity and food quality standards, highlighting their potential in safe agricultural wastewater treatment practices.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"36 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143083592","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, a flow-through electrochemical membrane (F-T) system was developed to simultaneously separate and age polystyrene microplastics (PS-MPs) in water. Under membrane pressure, PS-MPs were tightly pressed onto the surface of membrane electrode, forming a confinement space. The confinement effect overcomes the short lifetime of free radicals and accelerates the aging process of PS-MPs. This study identified the optimal conditions for aging PS-MPs in the F-T system, characterized the material properties before and after aging, and analyzed the degradation intermediates. After 8<!-- --> <!-- -->h of treatment, the oxygen-to-carbon ratio (O/C) of the PS-MPs following the F-T system was 2.00 times greater than that following the traditional flow-by (F-B) system. In addition, the unit energy consumption (kW·h/g) for the aging of PS-MPs in the F-T system was 645.19<!-- --> <!-- -->kW·h/g, which was 3.70 times lower than the F-B system. Free radicals, especially O₂^•- and •OH, played a major role in PS-MPs aging. Free radicals attack the main chain of PS-MPs, leading to subsequent chain breakage, hydrogen abstraction, and rearrangement reactions. After aging in the F-T system, the crystallinity, molecular weight, and zeta potential of the PS-MPs significantly decreased. In addition, carbon-centered environmental persistent free radicals formed on the surface of the PS-MPs. This study presents an energy-efficient method for the remediation of MPs in water and suggests that the aging efficiency can be increased through confinement.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"39 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143076955","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}

Monitoring carried out during these fires is limited in spatial resolution, meaning that the full extent of population exposure is difficult to estimate. In this study, we overcome these limitations by using a novel back-trajectory plume modelling approach, applied to PM₁₀ emission data from a significant tyre fire that occurred in the UK in 2010. This approach allows the calculation of an hourly emission rate that is then used in the forward modelling mode to predict hourly plume concentrations. An analysis of the modelled plume indicated that, as a reasonable worst case, up to 8,000 residents in areas adjacent to the fire may have been exposed to PM₁₀ concentrations that are deemed hazardous. Moreover, a vulnerability analysis showed that the exposed population had disproportionately poorer health than the national average, thus raising concerns about environmental justice.
