This study employs a data-driven personalized federated learning-based multi-agent attention deep reinforcement learning (PFL-MAADRL) algorithm to address the intake scheduling problem of three water intake pumping stations in urban water treatment plants. Personalized federated learning (PFL) is combined with long short-term memory (LSTM) modeling to create environment models for water plants, focusing on energy consumption, reservoir levels, and mainline pressure. The average accuracies of PFL-based LSTM (PFL-LSTM) models are 0.012, 0.002, and 0.002 higher than those of the LSTM model in the three water plants. Evaluation metrics were established to quantify the effectiveness of each pumping station's energy-efficient scheduling, considering constraints such as reservoir water levels and mainline pressure.

Wastewater released during marble processing should not be discharged into the sewer without treatment, in accordance with national and international legislation, due to the high concentration of colloidal substances it contains. In the treatment of these wastewaters, conventional chemical precipitation processes and high amounts of synthetic chemicals are commonly used. Another method that can be employed for treating these wastewaters is the chemical substance-assisted flotation process, where efficiency depends on the use of oil-based chemicals. In this study, the treatment of marble processing wastewater was carried out for the first time using the flotation process, with pyrolysis oils obtained from mixed plastic waste pyrolysis as the collector material. According to the treatment experiments, the flotation collector that showed the highest suspended solid (SS) and turbidity removal efficiency was the pyrolysis oil obtained at a pyrolysis temperature of 700 °C.

Compared to Fe<small>³⁺</small>-based coagulation, Fe<small>²⁺</small>-based coagulation resulted in higher DOC removal performance (increased by 63.5% in natural water), higher DBP concentration and water toxicity (increased by 31.3% for the cytotoxicity index and 18.5% for the genotoxicity index in natural water) during the PPFeC process. DBP concentration and toxicity decreased with the increase of the pre-oxidation time, and increased with the increase of PMS concentration. Furthermore, concentration of DBP and toxicity of water initially increased and then decreased with the increase of sedimentation time and coagulant concentration.

It is increasing at an alarming rate owing to significant contributions from natural and anthropogenic activities, which include mining operations, spraying pesticides, land filling, rock abrasion, volcanic eruptions, and fossil fuel combustion. Heavy metals are potentially toxic even at low concentrations and can induce hepatotoxicity, nephrotoxicity, neurotoxicity, carcinogenicity, genotoxicity, and cardiovascular toxicity. Thus, the removal of heavy metals is critical from an environmental perspective. Recently, various efficient adsorbents have been developed for the treatment of heavy metal contaminants, among which LDHs have received great interest owing to their outstanding features such as structural flexibility, biocompatibility, reusability, simple synthesis, low cost, high adsorption efficiency as well as rheological and swelling properties. This review presents an extensive summary of LDH-based adsorbents reported in the literature in the last ten years for heavy metal remediation. Herein, we systematically explore the recent advancements in aspects such as sources of heavy metals, toxicological effects, functionalization strategies, application of LDH-based hybrids in metal detoxification, influencing factors, and machine learning approaches. Moreover, this review highlights pivotal parameters such as isotherms, kinetics, thermodynamics, adsorption capacity, adsorption mechanisms, and optimised experimental values. Finally, we discuss the future perspectives in this promising field.

Even long-term exposure to concentrations below the MCL can also increase the risks of cancer. Iowa, a major agricultural producer, has grappled with decades-long nitrate pollution in its water systems due to intensive farming practices and animal feeding operations. To help in developing interventions and policies to protect public health, this study delves into long-term nitrate levels in 871 Iowa public water systems (PWSs) between 2012 and 2022 and examines sociodemographic disparities in potential nitrate exposure in drinking water. Average nitrate concentration in Iowa's PWSs increased between 2012 and 2016, reaching an average peak of 3 mg L<small>⁻¹</small> in 2016. 2.5% of 871 PWSs are classified as ‘high-risk’, with nitrate concentrations consistently exceeding 5 mg L<small>⁻¹</small> over the study period, primarily in eastern and western Iowa, where animal feeding operations are concentrated. The absence of nitrate removal processes at these PWSs contributes to the sustained elevated levels. On average, 7.4% of the state's population served by PWSs has been exposed to nitrate levels consistently exceeding 5 mg L<small>⁻¹</small> in the past decade. Disparities exist among various sociodemographic groups, with statistically significant higher exposure rates (10.1%, 9.6%, 9.2%, and 8.7%) observed for people whose incomes are below the federal poverty threshold ($26 496/year), older adults (65 years and above), people of colour, and children (5 years and younger). These disparities are particularly concerning as these populations often lack the resources to address the consequences of water contamination. Our study highlights inequities in Iowa's PWSs concerning potential nitrate exposures and underscores a need for nitrate remediation in specific areas. Addressing these disparities is crucial to safeguarding the health of vulnerable populations and promoting environmental justice in water management.</p>","PeriodicalId":75,"journal":{"name":"Environmental Science: Water Research & Technology","volume":" 4","pages":" 959-971"},"PeriodicalIF":3.5,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ew/d4ew00907j?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716566","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}

This study was conducted with ATZ concentration (3–20 mg L<small>⁻¹</small>), where the effects of electrode materials, current density, pH, and supporting electrolyte concentration were analysed. In general, the removal kinetics for ATZ were best described by the first-order model for both Al and Cu electrodes. The ATZ removal efficiencies were evaluated in real water matrices and found to be 79.85 ± 1.03, 75.92 ± 1.25, 70.58 ± 1.49, 68.09 ± 1.10, and 64.42 ± 2.25% in distilled deionized water, ground, lake, river, and wastewater, respectively using Cu electrodes. Removal of ATZ was higher (84.52 ± 1.04%) in the presence of microplastics as they served as coagulant aids. The effect of polarity reversal was examined to reduce anode fouling during electrolysis and longer intervals of 10 min yielded higher removal efficiencies than intervals of 5 min or no polarity reversal.

Organotin compounds (OTCs) are a class of persistent toxic substances with the effect of disrupting endocrine function, but potential human health risk due to organotin pollution in drinking water is still less understood. Understanding the occurrence and sources of OTCs in drinking water is crucial. Seventy drinking water samples collected from tap water, water boiling machines and water vending machines in Shanghai were analyzed for seven target OTCs. It is shown that the summed concentrations of target OTCs (∑OTCs) were up to 129 ng Sn L<small>⁻¹</small>, with the dominant species being dimethyltin (DMT), dibutyltin (DBT), monobutyltin (MBT) and monomethyltin (MMT). Furthermore, OTC pollution levels varied significantly among drinking water types and water source supply zones, with higher ∑OTC concentrations observed in tap water and zone A (supplied by an onshore reservoir next to the estuary). To quantify the sources of OTCs in drinking water, we employed two receptor models for comprehensive comparison: principal component analysis–multiple linear regression (PCA-MLR) and positive matrix factorization (PMF). Both models demonstrated excellent fit to the ∑OTC concentrations, with predicted ∑OTC values from each model showing a significant correlation (<em>r</em> = 0.9822, <em>p</em> &lt; 0.05). Two main sources of OTCs were identified by using both models: materials used in pipes and drinking fountains and emissions from maritime, agricultural and industrial activities, and the PMF model further distinguished sources associated with degradation. The PMF model emerged as the most appropriate model for organotin source apportionment in drinking water due to its detailed and accurate results. In brief, this study revealed that levels of organotin vary across different water sources and supply zones and identified the main sources of pollution from water sources and water supply processes.
