Gold exhibits fascinating photophysical and photochemical properties, making it valuable in various applications, including catalysis, fluorescent porous materials, fluorophores and medicine. However, high concentrations (0.075 and 0.006 mg/L) in fresh water are toxic, posing a threat to human health. Therefore, convenient chemical sensors are required for Au3+ monitoring. In this study, we present a novel carbazole-extended thiophene-containing electron rich organic compound (CT) and studied its interaction with Au3+ along with a range of sulphur containing small organic molecules through fluorescence, UV Vis. and NMR spectroscopy. Strong interaction between CT and Au3+ was further evaluated via SEM and DFT studies. Mechanism of interaction between CT and Au3+ was proposed to be chelation enhancement quenching effect (CHEQ) and the strong interaction explained based on the hard and soft acid and base (HSAB) theory. Interference studies showed highly selective interaction of CT with Au3+ in diverse conditions which makes CT a very promising fluorescent sensor. Therefore, real samples were also analyzed for the trace detection of Au3+ and ultra-fast, reversible and quantitative detection of Au3+ was achieved.

Bioremediation mediated by cytochrome P450 enzymes represents an effective strategy for the removal of Sulfonamides (SAs). However, the inherent limitations in the thermostability and catalytic activity of wild-type enzymes result in suboptimal remediation efficiency. Therefore, the development of highly efficient degradative enzymes is crucial for mitigating SAs pollution. 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, accurate and rapid identification of mutation sites and practical application of eco-friendly molecular design remain significant challenges for future research. This work provides theoretical support for the development of efficient degradative enzymes and the design of sustainable alternative compounds, contributing to the advancement of emerging pollutants pollution control strategies.

Pesticides are extensively used in agriculture to protect crops, but their environmental release, particularly as mixtures, raises concerns about effects on non-target organisms and ecosystem health. This study aimed to evaluate the toxicity of five pesticides used extensively on soybean crops - glyphosate, 2,4-D, paraquat, chlorpyrifos, and lambda-cyhalothrin- and their binary mixtures on the nematode Caenorhabditis elegans, a model organism in toxicology. Locomotion and growth assays were conducted to assess acute and chronic effects, and the RISK21 matrix framework was used to convey environmental risks based on the bioassay results combined with surface water monitoring data and modeled exposure estimates. Our results demonstrate significant reductions in locomotion and body length for all tested pesticides, with synergistic effects observed in binary mixtures. However, the risk-based analysis suggests that the estimated environmental concentrations of these pesticides pose minimal ecological risks. In conclusion, our work highlights the novelty of combining C. elegans-based toxicity assays in a risk-based approach to evaluate pesticide mixtures, offering a practical approach for predicting environmental impacts and promoting sustainable agriculture.

To protect against UV light, organic UV filters (UVFs) are widely used in sunscreen and various consumer products. Concerns regarding the potential health impacts of UVFs have been raised, however, information is mostly limited to their endocrine disruptions. The present study aims to investigate nephrotoxic potentials of four major organic UVFs, i.e., avobenzone (AVB), benzophenone-3 (BP-3), octocrylene (OC), and octyl methoxycinnamate (OMC), using a zebrafish model at different life stages. Test UVFs were applied during early (0–30 days post-fertilization (dpf)), and adult life stage (> 6 months old, 21 d exposure), and investigated for alterations in gene expression and/or kidney function. In juvenile fish (30 dpf), early life stage exposure to BP-3 and OMC caused significant induction of proteinuria. Moreover, regardless of life stage, key genes (wt1a, podocin, nephrin, cdh17, sim1a, and kim-1) responsible for kidney structure and function showed transcriptional alterations that support nephrotoxic potentials of the test UVFs. Our results demonstrate that exposure to widely used organic UVFs could impair normal biological processes for maintaining kidney health during both life stages. Considering the widespread use of organic UVFs among the general human population, the implication of this nephrotoxic potential warrants further investigation.

Microplastics have been discovered in the solid residuals from municipal solid waste (MSW) incineration plant, posing potential risks to the surrounding environments. 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. Our work prioritizes an alternative source of microplastic emissions and calls for further research endeavors.

Arsenic contamination of soils and groundwater affects nearly 106 countries, exposing an estimated 230 million people worldwide to a range of health risks including cancer, cardiovascular disease, diabetes, etc. It also poses significant risks to plants such as inhibited growth, reduced crop yields, and soil health degradation. This study investigates the arsenic (As)-induced changes in dynamics of proteome, sulfur metabolism, antioxidant enzymes and changes in stress tolerance mechanisms in Trigonella foenum-graecum 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 T. foenum-graecum to tolerate arsenic stress and enhance its phytoremediation potential.

Flow-electrode Capacitive Deionization (FCDI) is an innovative method for practical salt removal and recycling applications. Here, we report that FCDI facilitates the recovery of nitrate and fluoride salts from brines produced during the wastewater treatment process in a stainless steel pickling line. Laboratory-scale experiments with synthetic wastewaters were used to evaluate the influence of (a) the membrane thickness, (b) feed flow rates, and (c) applied voltage on the outlet concentrations and the average salt transfer rate. In continuous single-pass experiments, the flow rates of diluate and concentrate have the greatest influence on the resulting outlet concentrations in the FCDI process as they directly influence the residence time. The operating voltage of the FCDI process can be varied to increase the ratio of fluoride over nitrate for recycling.

Plants, as key components of trophic networks, play a critical role in the bioaccumulation of PFAS and their transfer to higher trophic levels. 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.

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}

Molluscs are significant aquatic organisms, which serve as bioindicator species. They are crucial for maintaining ecological balance as secondary consumers. Molluscs are threatened by pesticides such as pyrethroid insecticides. Pyrethroids are increasingly utilized to control insects in agriculture and gardening. It contaminates aquatic bodies through rainwater runoff and drainage-sewage systems. The current review will focus on the issue of increasing pyrethroid use and its biological effects on molluscs. Due to their highly lipophilic nature, pyrethroids pose a significant risk to these organisms by affecting their metabolites, producing reactive oxygen species, and influencing neurotransmitter actions. The threats to the molluscs and eventually to the concerned aquatic ecosystem warrant significant discussion and attention.
