The study aimed to assess how site, season, and species influence heavy metal accumulation in plant organs, chlorophyll content, and antioxidant compounds; to evaluate phytoremediation efficiency using bioaccumulation factors; and to explore the relationship between heavy metals concentrations in shoots and the behavior of chlorophyll and antioxidants. Heavy metal concentrations in water at all three sites fell within the safe irrigation limits. However, Cu and Mn levels in sediments exceeded global freshwater recommendations during summer. Fe and Mn levels in submerged species (<i>C. demersum</i> and <i>M. spicatum</i>) and emergent species'belowground tissues (<i>S. geminata</i>, <i>P. senegalensis</i>, and <i>L. adscendens</i>) surpassed the permissable limits in most seasons. In contrast, Zn levels in all studied species remained within the acceptable limits, while Cu levels in <i>S. geminata</i> and <i>P. senegalensis</i> roots exceeded the permissible limits during spring and summer, respectively. The bioaccumulation factors (BAFs) for submerged species exceeded one for all metals, whereas emergent species showed BAFs greater than one only for Mn. Translocation factors (TFs) for all metals were less than one, except for Zn in <i>P. senegalensis</i> and <i>L. adscendens</i>. Chlorophyll pigments in <i>S. geminata, M. spicatum</i> and <i>L. adscendens</i> negatively correlated with most heavy metals in shoots, while a positive correlation was observed in <i>C. demersum</i>. Also, heavy metals in shoots negatively correlated with total phenolics and flavonoids, carotenoids and phenolics, and phenolics in <i>C. demersum</i>, <i>M. spicatum</i> and <i>S. geminate</i>, respectively. In contrast, <i>L. adscendens</i> exhibited a positive correlation between most of these elements and antioxidant compounds. The differential relationships between the studied heavy metals in shoots and chlorophyll/antioxidant compounds suggest species-specific energy allocation strategies. Our results highlight the potential of these species for phytoremediation in contaminated aquatic ecosystems, and indicate that submerged species are suitable for hyperaccumulation, while emergent macrophytes function as accumulators for Mn and excluders for Fe, Cu, and Zn.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 7","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11270-025-07966-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143888724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Response Surface Methodology over Central Composite Design (CCD) was used to design the experiments. In addition, the effect of electrode material on EKR was investigated using two different electrodes, graphite, and stainless steel. The distribution and migration behavior of Cd in soil was explored through chemical speciation and sequential extraction procedure. The findings revealed that the voltage gradient and EDTA concentration were positively correlated with the removal efficiency at the optimized conditions of 2.5 V/cm and 0.15 M EDTA to achieve 27.8% removal in 10 h. The voltage gradient had a more profound effect on the removal efficiency as compared to EDTA concentration. The EKR treatment effectively reduced the bioavailability of Cd by removing water-soluble and exchangeable fractions and rendering the transformation of Cd to reducible and residual fractions. The Human Health Risk Assessment study was performed which revealed that EKR was successful in reducing the non-carcinogenic adverse effects by 29% and total carcinogenic risks from one in a thousand to one in a hundred thousand in adults, while children still exposed to high potential non-carcinogenic effects. The economic evaluation of all experiments concluded that the stainless steel electrode was more suited for Cd removal as compared to the graphite electrode with better removal (30%) and low specific cost (5.8 US$/g Cd). The study shows that EKR is successful in reducing the overall toxicity of Cd in soil and humans at a relatively low cost and less treatment time.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 7","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143883654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Association rule mining is employed to identify significant associations and hidden patterns. Meanwhile, supervised learning algorithms offer predictive power towards unseen data. As a result, the XGBoost model demonstrates the highest accuracy, reaching approximately 90%. The analysis of feature importance suggests that toxicity is significantly influenced by coat/functional and material. Concurrently, rule mining and classification machine learning results reveal that testing protocols hold equivalent significance to material traits regarding their impact on toxicity.

To elucidate the key factors influencing mercury methylation in soil, sampling surveys were conducted in May, July, and September at the Qixing Wetland in Shenyang. The findings indicated that the average concentrations of methylmercury (MeHg) and total mercury (THg) at Qixing Wetland were 3.91 ng·g⁻¹ and 173.45 ng·g⁻¹, respectively, with notably lower concentrations observed during the summer months. The highest rate of soil mercury methylation (%MeHg) was recorded in May at 4.43%, yielding an overall methylation rate of 2.91%. Correlation analysis, principal component analysis, and random forest modeling revealed that %MeHg is jointly influenced by the sampling month and various environmental parameters within the wetland ecosystem. In May, pH and dissolved organic carbon (DOC) emerged as primary determinants, whereas in July, fulvic-like substance proportions (%Fmax(A)) alongside soil organic carbon (SOC) were predominant; conversely, DOM spectral characteristics were the dominant influence in September.

Robustness checks—conducted via the generalized method of moments and a dynamic linear panel model—further confirm the consistency and reliability of the results. The findings reveal that political uncertainty significantly elevates carbon emissions and follows a nonlinear pattern: moderate political uncertainty tends to stimulate economic activity, resulting in higher emissions, while extreme uncertainty curtails economic activity, thereby reducing emissions. Moreover, a positive interaction between political uncertainty and mineral policy signals increased resource extraction in politically unstable settings. Conversely, interactions with technological innovation and energy transition display significant negative effects, suggesting that technological advancement and renewable energy adoption effectively counteract emissions growth under high political uncertainty.
