Therefore, this work first studied the effects of AC on the disinfection byproduct (DBP) formation with bromide and free radical-mediated reaction process. The results indicated that the proportion of brominated trihalomethanes/brominated haloacetic acids in the effluent was increased by 3–10% with AC and toxicity also increased. Fourier transform ion cyclotron resonance mass spectrometry results suggested that the relative intensity of halogenated byproducts including unknown brominated DBPs (Br-DBPs) was increased by 21%. In addition, the free radical-mediated reaction activated by AC also contributed to the generation of aliphatic halogenated and nonhalogenated compounds. The chlorine and bromide free radicals were activated by the AC. Though the reactive bromide species did not lead to the Br-DBP formation, HOBr or Br2 generated during the free radical chain reaction and the modification of the DOM properties through free radical reaction were responsible for the increase of Br-DBPs. Therefore, this study could provide a novel insight into the control of the risk of the toxic byproducts when using chlorine and AC simultaneously.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 3","pages":"1207–1215 1207–1215"},"PeriodicalIF":4.8,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143608951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its potential, the adverse effects of carboxylates on removing strongly adsorptive pollutants have not been thoroughly explored. Herein, based on a precomparison of three different micropollutants, p-arsanilic acid (ASA), a strong adsorbate, was used as a model pollutant to investigate its removal in goethite–carboxylate systems under UVA irradiation. The effects of oxalate, citrate, malate, and salicylate were assessed across varying carboxylate concentrations (0–2 mM) and goethite dosages (0.1–0.5 g·L–1). Key findings indicate that remarkable •OH contribution was only observed in oxalate and citrate systems following the generation of H2O2. Oxalate and citrate enhanced photodegradation but inhibited adsorption, with oxalate exhibiting a stronger promotional effect. In contrast, malate and salicylate suppressed adsorption without contributing to photodegradation. Without taking into account the suppression caused by competitive adsorption, one may overestimate the degradation of strongly adsorptive pollutants through a heterogeneous photo-Fenton-like process. These results contribute to a deeper understanding of the comprehensive effects of carboxylates in heterogeneous photo-Fenton-like systems, providing insights into the optimization of environmental remediation strategies.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 3","pages":"1364–1372 1364–1372"},"PeriodicalIF":4.8,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143608897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Owing to the differences in research conditions of relevant studies, there is limited knowledge regarding the evaluation of resistance performance and strategies among different freshwater microalgae when exposed to PFOA. In this study, two representative freshwater microalgae, Chlorella sp. and Microcystis aeruginosa, were selected to comprehensively explore their resistance to PFOA exposure. The results showed that Chlorella sp. exhibited superior resistance to PFOA compared to M. aeruginosa, primarily due to its higher photosynthetic efficiency and more rapid mobilization of antioxidant responses. Additionally, Chlorella sp. was capable of extracellularly degrading PFOA at low PFOA concentrations, thereby reducing the actual concentration of PFOA affecting the Chlorella cells. Furthermore, Chlorella sp. cells exhibited self-aggregation, driven by proteins in extracellular polymeric substances (EPSs), which provided protection against PFOA exposure. In contrast, the high polysaccharide content in the EPS secreted by M. aeruginosa led to increased PFOA adsorption and uptake by the cells, resulting in severe physiological effects. This study enhances the understanding of the pivotal roles played by physiological characteristics and behavioral patterns of freshwater microalgae in their resistance to PFOA.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 3","pages":"1481–1491 1481–1491"},"PeriodicalIF":4.8,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143608963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike in urban areas, the planning and management of RST in rural settings are significantly more complex and often constrained by limited budgets. It is significant and urgent for provincial or municipal governments to identify the villages with the highest priority for RST investment. This study proposes a decision-making model to prioritize villages for RST investment, balancing economic and ecological benefits with life-cycle costs. The model was applied across 104,246 villages in Guangdong, Henan, Hunan, Shanxi, Qinghai, and Liaoning Provinces in China, and it successfully generated priority maps for each province. Results indicate that the return on investment (ROI) for the top 5% of villages in Guangdong Province reached 1.75, which is 20.3% higher than that of random investments. Furthermore, the corresponding average revenue was 6 times greater than those of randomly selected villages. The model also demonstrated strong performance in the other 5 provinces. Factor importance analysis, utilizing random forest regression models alongside SHAP methodology, reveals that population size is the most influential factor in prioritization. The decision-making model offers scientific and efficient solutions for optimizing RST investments while maximizing marginal benefits and enhancing the efficiency of ecological protection funds.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 3","pages":"1148–1157 1148–1157"},"PeriodicalIF":4.8,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143608900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ESBL-Ec abundance and prevalence, and ESBL-Ec to E. coli ratios were significantly higher in the two highly impacted lakes; however, in the “pristine” bird sanctuary lake, ESBL-Ec were also present. The CQT-CRO format yielded reasonable qualitative (K = 0.603) and quantitative agreement (intraclass correlation coefficient = 0.849) with the TBX-CRO format. Based on random testing of a single colony per sample, CRO performed poorly for screening the ESBL phenotype among E. coli environmental isolates. Notably, ESBL-Ec isolates were not associated with an increased number of resistance phenotypes compared with non-ESBL isolates. Instead, the number of resistance phenotypes was associated with the lake from which the sample was collected. Our experience suggests when ESBL-Ec are abundant, such as in high-burden settings, the usefulness of the phenotype as a proxy for antimicrobial resistance in the environment is greatly diminished.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 3","pages":"1321–1330 1321–1330"},"PeriodicalIF":4.8,"publicationDate":"2025-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143608775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are the predominant lotic ecosystem in the United States Southeastern Coastal Plain, a region experiencing some of the nation’s highest rates of development. This study assessed variability in DOM concentration and composition across forested to urbanized blackwater systems in coastal South Carolina, U.S. Dissolved organic carbon and nutrient concentrations as well as absorbance and fluorescence optical properties reveal that urban sites have lower concentrations, elemental ratios, and less complex DOM. In contrast, forested blackwater sites have concentrations an order of magnitude higher, elevated elemental ratios, and molecular size dominated by refractory terrestrial-like DOM. Urban blackwater rivers were observed to have DOM concentrations and composition more similar to brown water systems than rural blackwater systems. These findings suggest that the urbanization of blackwater ecosystems results in lower concentrations and the export of simpler, more labile DOM, potentially lowering dissolved oxygen concentrations, increasing atmospheric carbon emissions and other negative impacts. To protect blackwater systems, baseline DOM concentrations and composition must be established to decipher impacts on water quality due to naturally occurring versus anthropogenic activities and to properly assign classifications to these diverse systems across the U.S.Dissolved organic matter (DOM) composition was examined across blackwater coastal ecosystems, revealing transformations in DOM content associated with urbanization with implications for water quality and policy.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 3","pages":"1281–1294 1281–1294"},"PeriodicalIF":4.8,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsestwater.4c01054","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143608848","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}
