Finally, Ti/CoO@ZIF-67 composite electrode was synthesized. In order to find the PEC electrode with the best performance, we optimized the experimental system by adjusting the amount of organic ligand (0.01 mol, 0.015 mol, 0.02 mol, 0.025 mol). The PEC activity of Ti/CoO@ZIF-67 electrode was studied by electrochemical properties and degradation efficiency of Ti/CoO@ZIF-67 electrode for active brilliant blue (KN-R). The results show that the Ti/CoO@ZIF-67–0.02 electrode exhibits the largest specific surface area, the smallest charge radius, the fastest charge mass transfer rate and the highest PEC degradation efficiency for KN-R. The composite electrode with different amount of organic ligand showed higher degradation efficiency than the single component electrode. This is due to the staggered band structure of CoO and ZIF-67, which accelerates the effective separation of photogenerated electrons and holes on the surface of the electrode, and improves the mineralization effect of the composite electrode on organic polymer materials. This study provides an application strategy for the construction of composite heterojunction materials.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 2","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142976615","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}

This study assessed the ecotoxicological impacts of tannery effluents on <i>Scinax fuscovarius</i> tadpoles and <i>Poecilia reticulata</i> fish. Tadpoles and fish were exposed to environmentally relevant dilutions (0.3%) of raw tannery effluent (RTE) and effluent treated with mercerized microcrystalline cellulose particles (TTE) for 15 days. RTE exposure caused a 74.9% reduction in catalase (CAT) activity and a 50% increase in micronucleated erythrocytes in tadpoles, alongside heightened oxidative stress and inflammation. In fish, RTE exposure led to a 30% increase in superoxide dismutase (SOD) activity and moderate cytogenotoxic effects, reflecting their lower chromium (Cr) accumulation (0.5 mg/g in fish vs. 1.2 mg/g in tadpoles). TTE treatment significantly reduced Cr concentrations by 60% in tadpoles and 50% in fish, mitigating toxicity. However, residual sublethal effects persisted, including oxidative stress markers and nuclear abnormalities in both species. These findings highlight the differential sensitivity of aquatic species to tannery effluents and the partial efficacy of TTE in reducing toxicity. The results provide critical data for advancing remediation strategies, emphasizing the need for technologies capable of addressing residual toxicity. Furthermore, this study underscores the importance of multi-species ecotoxicological assessments and biomarker-based approaches in regulatory frameworks to ensure the ecological safety of treated industrial effluents. Future studies should explore long-term and transgenerational impacts to build a comprehensive understanding of these pollutants' ecological and evolutionary consequences.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":"236 2","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142941270","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}

This study proposes a sequential ozonation system to degrade two ASCs: 4-phenol sulfonic acid (4-PSA) and 2-naphthalene sulfonic acid (2-NSA). The sequential treatment consists of two stages: first, conventional ozonation is applied to partially degrade the target compounds and produce intermediate byproducts, with ozonation time of 20 or 40 min. In the second stage, a commercial metal oxide (NiO or CuO) is used as catalyst with ozone to further degrade the intermediates generated in the first stage. The sequential approached achieved nearly complete mineralization of both ASCs, significantly surpassing the total organic carbon (TOC) removal (around 61%), when the catalyst was added at the start of ozonation and maintained for 2 h. The success of sequential system is attributed to the reactive oxygen species (ROS) generated by the catalyst, which mostly eliminate byproducts formed during conventional ozonation. Contrary to single catalytic ozonation, where ROS are generated since the beginning and act on both intermediates and target compounds, reducing the TOC removal around 33%. Additionally, sulphate ions are released during the ASCs elimination, which can inhibit the catalytic activity by blocking the active sites; the sequential process mitigates this effect by minimizing catalyst exposure to sulphate ions. FTIR and XPS analyses confirmed the presence of these ions on the catalyst surfaces. Therefore, sequential ozonation reduces the metal leaching and offers high ASCs mineralization efficiency compared to conventional ozonation processes, and thus, could have a potential use for treating ASCs contaminated effluents.</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 2","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142939420","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}

In this study, we developed an H₂S-modification method to prepare sulfide nanoscale zero-valent iron (S-nZVI) to improve the acid resistance and the adsorption performance of adsorbents for As in sulfide-abundant conditions. The results showed that the H₂S-modification method expanded the pH windows with excellent As(III) removal efficiency from 3 to 7, and at pH value of 3, the As(III) removal efficiency reached 99%. Under pH = 3, the concentration of iron released from nanomaterials decreased from 200 to 20 mg/L, which is attributed to the protection of the surface by the FeS_x layer. Moreover, through H₂S-sulfidation, H₃AsO₃ (As-O species) transformed to As-S species, which were more challenging to remove than As-O species. In As(III)-S(-II) solution, S-nZVI adsorbed 95% of As(III) in the range of pH 1–5, and the excessive S(-II) could react with Fe(III) to accelerate the cycle of Fe(III)/Fe(II). This improved the efficiency of the Fenton reaction to enhance the oxidation of As(III). Furthermore, consumption of the S(-II) could promote the transformation from As-S species to As-O species.

Water sampling was carried out at 13 stations within the Main Lake, Sendayan Lake and Teratai Lake through the DotS sampling method. The potential pollution sources affecting water quality were quantified using a statistical approach, including Pearson's correlation and principal component analysis/factor analysis (PCA/FA).

Two factors were found to account for over 82% of the total variation in the dataset when PCA was used to compare the compositional patterns among the samples that were analysed.

Organic matter and nutrient regimes mainly affect water quality.
