Interference studies showed highly selective interaction of <strong>CT</strong> with Au³⁺ in diverse conditions which makes <strong>CT</strong> a very promising fluorescent sensor.

Additionally, identifying environmentally friendly alternatives with lower toxicity is beneficial for source control of SAs. This work adopts an integrated strategy that combines bioremediation and source control. Utilizing multiple computational strategies, we rationally designed and screened novel high-efficiency enzyme variants of CYP120A1 specifically targeting SAs degradation, and concurrently evaluated the molecular properties of pollutants to design new green alternatives. This study successfully identified 18 single-mutation enzyme candidates with enhanced thermostability and catalytic activity. Furthermore, we designed three green alternatives, SDZ-13, SDZ-19, and SDZ-27, which exhibit lower toxicity and significantly improved binding affinity with the degradative enzymes.

However, there exists a lack of evidence on the presence and characterizations of atmospheric microplastic emission from MSW incineration, which is considered more hazardous due to size reduction. Hence, we collected particles from flue gas emitted by a circulating fluidized bed incinerator, to investigate the morphology, chemical structure, and emission abundance of microplastics. Further, particles from different stream locations were collected to identify the effects of air pollution control devices on the microplastic abundance and chemical structures. Results indicate the predominant length of the microplastics in the flue gas ranged from 10 to 40 μm at different locations. The major polymer types of microplastics were polyvinyl chloride and polyacrylamide, resulting from inherent Cl elements and selective non-catalytic reduction in MSW, respectively. Based on the field data, the atmospheric microplastic emission was estimated at 2.1 × 10¹² pieces/yr, turned out to be a pivotal contributor to the atmospheric microplastics. Notably, the unique microplastic chemical properties pose a higher threat to human health than conventional plastics.

This study investigates the arsenic (As)-induced changes in dynamics of proteome, sulfur metabolism, antioxidant enzymes and changes in stress tolerance mechanisms in <em>Trigonella foenum-graecum</em> under different concentrations. Hydroponically grown 30-day-old plants were exposed to 0, 25, 50, 75, and 100 µM As for 10 days. The results showed increased oxidative stress and reduced growth at higher As concentrations. Enzymes related to thiol metabolism, including ATP sulfurylase and serine acetyltransferase, were significantly upregulated at 50 and 100 µM As, alongside increased cysteine and glutathione content linked to the upregulation of S-deficiency-induced 2 isoform X2 protein. Antioxidant enzymes (SOD, APX, CAT, GR, GPX, and GST) also exhibited enhanced activity. Proteomic analysis revealed 46 differentially expressed protein spots, including proteins involved in growth and photosynthesis, such as gibberellin 20-oxidase and RuBisCO. Defence proteins like trehalose phosphate phosphatase, calmodulin, and pectinesterase were upregulated, aiding stress tolerance. Sulfur metabolism proteins, such as glutathione S-transferase, were activated to counteract oxidative stress. Metallothioneins (MTs) were notably upregulated, contributing to arsenic detoxification. Transport proteins, including ABC transporters and ATP synthase beta subunits seems to play important roles in arsenic resistance. Additionally, proteins involved in protein degradation and redox balance, such as the RING finger protein and selenoprotein W1, supported the plant's adaptive response. These findings highlight the complex proteomic changes that enable <em>T. foenum-graecum</em> to tolerate arsenic stress and enhance its phytoremediation potential.</div></div>","PeriodicalId":93463,"journal":{"name":"Journal of hazardous materials letters","volume":"6 ","pages":"Article 100153"},"PeriodicalIF":6.6,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144471370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces an innovative methodology using timsTOF fleX MALDI-2 to visualize the spatial distribution of PFAS in plant tissues. Radish was selected as the model plant due to its global popularity as a widely consumed vegetable. DAN (1,5-diaminonaphthalene) was used as the MALDI matrix, and the mass spectrometry operating conditions were optimized to acquire the best PFAS signals. The results show that long-chain PFAS predominantly accumulated in the xylem of the edible storage root, where their high hydrophobicity limits upward translocation. In contrast, short-chain PFAS and PFOA exhibited stronger signals in the cortex and periderm, likely due to alternative transport pathways. This differential distribution highlights the significant influence of PFAS physicochemical properties, such as chain length and hydrophobicity, on their in-planta transport mechanisms. By precisely mapping PFAS within plant tissues, this study provides a powerful tool for identifying high-risk edible tissues and assessing human exposure risks through PFAS-contaminated crops. It also reinforces the urgent need for sustainable remediation strategies to reduce PFAS levels in agricultural systems, thereby safeguarding food safety, ecosystem health, and human well-being.</div></div>","PeriodicalId":93463,"journal":{"name":"Journal of hazardous materials letters","volume":"6 ","pages":"Article 100141"},"PeriodicalIF":6.6,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143169644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
