However, few studies have quantitatively estimated the effects of these stressors on Taihu water chemistry. Here, the MAGIC model was used to simulate and predict long-term changes in lake water chemistry after adaptive modifications. Long term historical water chemistry data and our field data on soil properties were used to calibrate the model. The result indicated that Cl-, Na+, and SO42- were the most sensitive to wastewater discharges, resulting in around an 80% increase in Cl- and Na+; and after \"wastewater calibration\" the modelled results were in good agreement with calculated ones. Modelled Ca2+ and Mg2+ losses were consistent with measured results before 2000, and the acid deposition-induced effect was not different from the combined effect of acid deposition and N fertilization application; while after that base cation losses caused by dual acidification were significantly higher than those caused by acid deposition alone, which corresponded well with the N fertilizer consumption and SO2 emissions. The modelled results indicated that after 2000, the annual loss of Ca2+ and Mg2+ caused by double acidification (acid deposition and N fertilization) was 27% and 11% higher than that caused by acid deposition, respectively. The MAGIC prediction based on different scenarios showed that the reduction of wastewater discharge would effectively inhibit the increase of Cl-, Na+, and SO42-, while the effect of acidification would last longer than expected even under SO2 reduction. This work is expected to provide a scientific basis for integrated watershed management and recovery planning.","PeriodicalId":74,"journal":{"name":"Environmental Science: Processes & Impacts","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197502","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}

These substances are believed to be associated with a range of toxic effects. Reproductive toxicity warrants greater attention due to its potential impact on offspring development. This article reviews and summarizes the literature from the past fifteen years on the studies of reproductive toxicity in model organisms induced by PFASs. This article organizes the studies according to the five most commonly used model organisms including mice, rats, zebrafish, Oryzias, and Caenorhabditis elegans. By reviewing the literature, it was found that PFASs primarily induced reproductive toxicity through gonadal damage, disruption of sex hormones, and effects on offspring development. Moreover, mammals, rats and mice possess many conserved signaling pathways with humans, making them valuable models for studying various diseases and metabolic pathways. Zebrafish and Oryzias are well-suited for examining chronic toxicity at environmentally relevant exposure levels, with their high-throughput screening capacity enabling efficient and low-cost assessment of transgenerational effects. In summary, this study systematically reviews the reproductive toxicity of PFASs in model organisms, offering a scientific foundation for optimizing model selection, exploring intervention strategies, and shaping future research directions.","PeriodicalId":74,"journal":{"name":"Environmental Science: Processes & Impacts","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145184291","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}

However, the lack of hydrolysis rate constants (kH) and aqueous hydroxyl radical degradation rate constants (kOH) limits the environmental persistent assessment of antibiotics. The present study addresses this gap by developing prediction models using multiple linear regression and three machine learning algorithms (i.e., random forest, support vector machine, and extreme gradient boosting (XGBoost)), based on a dataset of 69 kH and 80 kOH values. The XGBoost models, identified as optimal, were employed to fill in missing data in the original dataset. Subsequently, a multi-task model capable of simultaneously predicting kH and kOH values was developed with good performance. The application domain was characterized by Williams plots. Furthermore, Shapley Additive exPlanations analysis was employed to identify key molecular descriptors influencing degradation rates, which provides insights into the underlying degradation mechanisms. This approach not only facilitates the simultaneous prediction of kH and kOH values for various new pollutants, but also enhances the understanding of how molecular structure affects their synergistic degradation kinetics in aquatic environments, thereby significantly contributing to the assessment of environmental persistence of emerging contaminants.","PeriodicalId":74,"journal":{"name":"Environmental Science: Processes & Impacts","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145184300","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}

Mercury (Hg) is widely used to extract gold and its release through burning amalgams has led to soil contamination near mining sites. However, the fate and speciation of Hg in soils remains poorly understood, especially the reactivity or methylation potential of soil particles eroded into rivers. In this study, Hg contamination levels and speciation were assessed in water, soil, and sediments from five ASGM districts along the Mouhoun River. Surface waters near riverside mining sites showed high levels of particulate Hg (11-239 ng L-1), while more arid sites showed Hg contamination localised to ore-washing ponds. Mercury thermodesorption and selective extraction analysis revealed that in soils collected in the vicinity of amalgam burning sites, around 10% of total Hg (THg) was elemental (Hg0), with most remaining Hg bound in the divalent state to amorphous iron oxides (∼60% THg) and organic matter (∼30% THg). In river sediments, Hg bound to amorphous iron was halved, while methyl Hg (MeHg) levels increased fivefold (0.7 ± 0.2 ng g-1) suggesting that iron reduction in sediments promotes MeHg production and accumulation. These results highlight the potential risks of Hg exposure for local communities and the need for regional Hg management in ASGM areas.","PeriodicalId":74,"journal":{"name":"Environmental Science: Processes & Impacts","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145135928","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}

Yet, our understanding of the rhizosphere processes driving mercury (Hg) cycling remains limited. The unique characteristics of the rhizosphere microenvironment, particularly the elevated binding capacity and redox activity of microbial-derived carbon, support the hypothesis that localized organic matter drives Hg enrichment and speciation shifts, ultimately governing Hg biogeochemical cycling at the soil-vegetation interface. Herein, we report that in a subtropical forest, the rhizosphere soil (Rs) has significantly higher Hg concentration than that in non-rhizosphere soil (NRs), specifically in the deeper soil horizon (41.2 ± 42 for Rs versus 14.3 ± 22.8 ng g-1 for NRs). Similarly, the Δ199Hg values in deeper Rs were significantly more negative than those in deeper NRs, with an average shift of -0.21 ± 0.14‰. Further correlations between Δ199Hg and indexes of rhizospheric microbial carbon indicated that the abiotic reduction of Hg by microbial organic matter contributed to this shift of Δ199Hg between Rs and NRs. Finally, the Rayleigh model estimated an average 32-72% Hg reduction in deeper soil horizons, highlighting the complex interactions between plants, microorganisms, and organic matter within the rhizosphere regarding Hg accumulation and sequestration.","PeriodicalId":74,"journal":{"name":"Environmental Science: Processes & Impacts","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129584","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}

However, evidence on the effects of air pollution on embryonic developmental outcomes in populations undergoing assisted reproductive technology (ART) remains limited. Herein, a total of 17 941 couples of patients who underwent in vitro fertilization (IVF) in the reproductive center of the hospital between January 2017 and December 2021 were included. The exposure of couples to PM2.5 and ozone (O3) was estimated based on the Tracking Air Pollution in China and their geographic coordinates. Generalized additive models and segmented linear regression analyzed the associations between PM2.5/O3 exposure and embryological outcomes, including synergistic interactions. The results revealed that exposure to PM2.5 and O3 was significantly negatively associated with normal fertilization rates, high-quality embryo rates, and blastocyst formation rates. PM2.5 and O3 exhibited interactive effects in their negative impacts on high-quality embryo rates and blastocyst formation rates. Subgroup analyses revealed that both ambient ozone and PM2.5 exposures were consistently associated with reduced high-quality embryo and blastocyst formation rates across multiple maternal age and BMI categories, particularly among younger and normal-weight women. Significant interaction effects between ozone and PM2.5 were observed primarily in women aged < 35 years and those with BMI < 24 kg m-2, indicating heightened vulnerability in these groups. These findings emphasize the coordinated control of O3 and PM2.5 levels to mitigate adverse effects on embryonic development.","PeriodicalId":74,"journal":{"name":"Environmental Science: Processes & Impacts","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129601","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}

On a landscape-scale, factors controlling Cr and V solubilization to groundwater in the Piedmont are understood to be largely associated with the regional geology. However, the specific mechanisms mediating (bio)geochemical interactions among heterogeneous geologic materials and redox active chemical inputs in the subsurface are poorly understood. The specific goal of this research was to elucidate the chemical controls on the solubilization of Cr and V from saprolite - chemically weathered rock between soil and bedrock - to groundwater. We conducted 40-day batch incubation experiments using chemically variable saprolites from the NC Piedmont to evaluate dynamics of Cr and V solubilization as influenced by interactions between common chemical inputs. Organic carbon (citric acid) additions stimulated dissolution of Cr and V to the aqueous phase, with abiotic controls generating greater concentrations of Cr and V than biotic incubations. Addition of the oxidant manganese (Mn)-oxide suppressed solubilization of Cr and V from the saprolites. Across all experiments, dissolved Cr and V concentrations were positively correlated (R2 = 0.81-0.99) with dissolved iron (Fe) concentrations. Overall, these results highlight how organic carbon inputs can modulate the cycling and solubilization of Cr and V in heterogeneous media, and our results may be impactful in making better predictive and vulnerability assessments plans, particularly in delineating abiotic vs. biotic roles driving Cr and V dissolution to groundwater.","PeriodicalId":74,"journal":{"name":"Environmental Science: Processes & Impacts","volume":" ","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145111534","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}
