CWB was prepared by calcining RWB at 900 °C for 3 h. Batch adsorption experiments were conducted, and the data fitted best with the Langmuir isotherm model. The adsorption kinetics followed the pseudo-second-order and intra-particle diffusion models. Although calcination improved the surface area and porosity, RWB exhibited higher Fe(II) removal efficiency, likely due to its richer mineralogical composition, particularly the clay content. The results suggest that modification by calcination does not necessarily enhance adsorption performance. The proposed mechanisms involve chemisorption, electrostatic attraction, cation exchange, surface complexation, and adsorption-oxidation. Additionally, RWB showed better performance than CWB in reducing Mn, Ca hardness, NH₃, NO₃-, NO₂-, and TDS during groundwater treatment. Therefore, RWB offers a more cost-effective and sustainable option for water purification without requiring energy-intensive modification.","PeriodicalId":15530,"journal":{"name":"Journal of contaminant hydrology","volume":"275 ","pages":"104692"},"PeriodicalIF":4.4,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144812024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

DBP-induced ferroptosis compromised zebrafish embryogenesis, leading to reduced tail bent rate and heart rate, as well as elevated mortality and deformity. Larval neurobehavioral deficits, assessed through spontaneous locomotion, light/dark transition, and vibrational startle response assays, manifested as significant hypoactivity in total distance, velocity, maximum acceleration, and cumulative mobility.

The bioaccumulation of such PPCPs, followed by their degradation in edible crops, is an alarming concern as a potential exposure route to humans. This study selected two commonly prescribed medicines, diclofenac (DLF) and sulfamethoxazole (SMX), to dissect their fate in carrots. Results from carrot cell culture models illustrated their rapid absorption over a 120-h incubation period. Incubation time and initial exposure levels had significant effects on the dissipation of these parent compounds, along with a notable interaction. Metabolites were believed to be transformed through Phase I and II processes, while the hydroxylated and oxidized derivatives were the most abundant products in carrot cells for DLF and SMX, respectively. Whole-plant models further revealed the behavior of the parent compound therein, where DLF and SMX tended to accumulate in the root tissues of carrots rather than leaves, accompanied by limited translocation. Comparable patterns were also observed for their metabolites, with relatively high proportions in roots, attributed to the accumulation and the differences in metabolic activity between the roots and leaves. The consumption of these DLF or SMX-contaminated carrots, together with their metabolites present in the edible part, could pose significant risks to human health, causing concern for adults and toddlers. These findings provided valuable insights for future studies on the bioaccumulation and biodegradation of DLF and SMX in edible crops and the associated health implications.","PeriodicalId":311,"journal":{"name":"Environmental Pollution","volume":" ","pages":"126917"},"PeriodicalIF":7.3,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144768184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Surface daily PM2.5 observations exceeded 100 µg m-3, affecting major cities such as New York City and Philadelphia, while many areas lacked PM2.5 monitors, making it difficult to assess local air quality conditions. To address this gap, we developed a WRF-CMAQ-BenMAP modeling system to provide rapid, spatially continuous estimates of wildfire-attributable PM2.5 concentrations and associated health impacts, particularly benefiting regions lacking air quality monitoring. CMAQ simulations driven by two wildfire emissions datasets and two meteorological drivers showed good agreement with PM2.5 observations, with linear regression results of R2 ∼0.6 and slope ∼0.9. We further quantified uncertainties introduced by varying emissions and meteorological drivers and found the choice of wildfire emissions dataset alone can alter PM2.5 simulations by up to 40 µg m-3 (∼40%). Short-term health impacts were evaluated using the BenMAP model. Validation against asthma-associated emergency department (ED) visits in New York State confirmed the framework's ability to replicate real-world outcomes, with ED visits increased up to ∼40%. The modeling results identified counties most severely affected by wildfire plumes, the majority of which lack regulatory air quality monitors. Our approach highlights the value of integrated modeling for identifying vulnerable populations and delivering timely health burden estimates, regardless of local monitoring availability.","PeriodicalId":11747,"journal":{"name":"Environmental Research Letters","volume":"20 11","pages":"114042"},"PeriodicalIF":5.6,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12533810/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145328470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fish were sampled from seven oil affected reef areas and one non-affected, 17, 24 and 34 months after the oil spill. Analysis of biliary PAHs, biochemical and genotoxic biomarkers were carried out.

Biliary PAHs and ethoxyresorufin-O-deethylase (EROD) activity in fish sampled from Janga, Paiva, Suape, Serrambi, Carneiros and Mamucabas reefs were higher than in specimens from Cupe reference area. Male and immature individuals presented higher activities than females for EROD, Glutathione S-transferase and catalase and lower values for superoxide dismutase and glutathione. Increased micronuclei frequencies were observed in Paiva, Suape, Serrambi and Carneiros samples. The results indicate that these reef areas are not being influenced by the 2019 oil spill. Contamination by PAHs occurs chronically in these locations such as the urbanized Janga reef area, where the highest bile PAH concentrations and EROD induction were detected. The integrated index of biomarker responses indicated changes in biochemical biomarkers in all reef areas related to Cupe, possibly reflecting exposure to other unmeasured contaminants.

This study uses the SpatialMaxEnt model to assess the present and future habitat suitability of the vulnerable Cuvier's gazelle in Northwest Africa under climate change scenarios. Key predictor variables such as coldest quarter precipitation (40.1%) and temperature seasonality (15.5%) were identified as the most influential factors in determining the present distribution of the species. The model showed high reliability (AUC = 0.961, CBI = 0.992) and predicted 587,825 km2 (18.05% of the study area) as presently suitable habitat using the maximum training sensitivity plus specificity threshold. The 10th percentile training presence threshold yielded a smaller extent of 452,526 km2 (14%), reflecting its more conservative nature. In both cases, highly suitable areas were concentrated in mountainous regions such as the Tunisian Dorsal, the Algerian Tell Atlas, and the Moroccan Anti-Atlas range. The future projections reveal consistent patterns of range contraction under climate change. Under SSP2-4.5, reductions of up to 22–26% by 2081–2100, while SSP5-8.5 forecasts more severe declines of 52–59%.
