High-strength NMP wastewater was difficult to treat due to its strong toxicity to microorganisms. Since aerobic granular sludge (AGS) had a unique layered structure and exhibited high tolerance to organic loading rate (OLR), herein, AGS was directly cultivated with the influent NMP of 10,000 mg/L (OLR of ∼5.8 kg COD/(m3 d)) in a sequencing batch reactor with the inoculum of activated sludge. Granulation was successfully completed in 20 days with a D50 of 520 μm, SVI30 of 53.1 mL/g, and SVI30/SVI5 of 0.9. COD and TN removal ratio were maintained at >97.2% and 28.3%–46.5% during the long-term operation, in which genera Methylobacillus, Allorhizobium-Neorhizobium-Pararhizobium-Rhizobium, and Arenimonas were the main bacteria. The relatively low TN removal was similar to other biological treatment processes, which was primarily due to the evident stepwise carbon removal and nitrogen release, as well as the suppression of nitrifying bacteria. Furthermore, an up-to-standard AGS-two-stage-A/O process was developed using Aspen Plus V10. To our knowledge; this study first developed the AGS system for high-strength NMP wastewater treatment, and it showed the highest NMP-stress tolerance in various NMP biodegradation strategies.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 9","pages":"5575–5584"},"PeriodicalIF":4.3,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145036655","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}

In this study, we investigated the spatiotemporal variation, potential sources, and ecological risk of seven typical OPEs in water samples collected from the largest tributary of the Yellow River during the wet, dry, and normal seasons. All target OPEs were detected; triethyl phosphate (TEP) and tris(2-chloroethyl) phosphate (TCEP) were the most commonly detected target compounds (100%). The results indicated that the total concentration of OPEs ranged from 0.73 to 2023.62 ng/L in water. Concentrations of OPEs were significantly higher in the normal season (12526.27 ng/L) and wet season (12047.81 ng/L) than in the dry season (7886.37 ng/L). The spatial distribution was dominated by Cl-OPEs and Aryl-OPEs, which were mainly concentrated in the central and lower sections with frequent urban activities. Principal component analysis and Spearman’s correlation analysis demonstrated that urban wastewater discharge, industrial production, and atmospheric wet deposition were potential sources of OPEs. The species sensitivity distribution and assessment factor were used for the ecological risk assessment of OPEs. The OPEs presented low ecological risk (RQ < 0.01) at different periods. However, tris(2-butoxyethyl) phosphate (TBEP) and tris(1,3-dichloro-2-propyl) phosphate (TDCPP) posed relatively higher ecological risks.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 9","pages":"5405–5415"},"PeriodicalIF":4.3,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145036653","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}

Herein, we studied the oxidation of a TWP leachate (85 mg C/L) by three common manganese (Mn) (hydr)oxides (β-MnO2, δ-MnO2, and γ-MnO2) (500 mg/L) in aqueous suspensions at varying pH (3, 4, and 5). The released amount of Mn2+ positively correlated with the TOC loss of leachate, indicating the coupled oxidation of leachate with reductive dissolution of Mn (hydr)oxides. The strongest reduction shown for β-MnO2 at pH 3 was accounted for by the intensified leachate adsorption assisted by acidic dissolution. This was further verified by electrochemical quartz crystal microbalance (EQCM) analysis to in situ monitor changes of mass and redox potential at the surface of electrodeposited Mn (hydr)oxide by comparison with inert polystyrene nanoparticles. Fluorescence analysis showed that new quinone compounds were formed after reacting with β-MnO2, whereas some quinone compounds were mineralized or structurally altered after reacting with δ-MnO2. Compared with pristine TWP leachate, only the leachate reacted with δ-MnO2 at pH 3 exhibited enhanced luminescent bacterial toxicity (by 96.2%) attributable to oxidized quinone compounds and lower-molecular-weight compounds produced from oxidation desulfurization, as revealed by Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) analysis.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 9","pages":"5661–5671"},"PeriodicalIF":4.3,"publicationDate":"2025-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145036648","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}

Specifically, the inclusion of FeP in the Sch/FeP composite markedly increased the content of ≡Fe(II) species, thereby improving the activation of H2O2 to produce substantial quantities of •OH and •O2– radicals. Sch/FeP-driven heterogeneous Fenton exhibited high total organic carbon (TOC) removal (∼60%) and utilization efficiency of H2O2 (100%) after 20 min. Furthermore, Sch/FeP exhibited excellent degradation performance across a broad pH range (2–10), which could be attributed to the SO42– substitution reaction.

Yet, ineffective oversight and accountability among stakeholders often undermine water resource management (WRM). To address this issue, we introduce a framework called S2WRM, which integrates a dual strategy: a game theory-based method and a blockchain-based system. In the game theory component, we apply a Stackelberg game, positioning the Water Resource Management Authority (WRMA) as the leader and industrialists and farmers as followers. Through this sequential game, dynamic pricing is determined as the leader establishes pricing strategies across various scenarios, analyzing usage trends to boost WRMA revenue. In addition, a blockchain incentive system is implemented, using ERC-20 contracts to mint and distribute tokens as rewards. This blockchain framework is built on the Ethereum platform, with Stackelberg simulations coded in Python. Analysis of different scenarios reveals key insights: first, blockchain-based incentives improve consumption oversight, fostering transparency in stakeholder supply chains second, WRMA revenue rises as blockchain reduces overhead costs tied to dynamic pricing and third, sustainability is advanced through token limits and penalties.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 9","pages":"5134–5144"},"PeriodicalIF":4.3,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145036317","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}

This study investigated the adsorption of eight PFAS at 10, 20, and 30 °C. Short-chain PFAS adsorption decreased up to 4-fold with a temperature increase from 10 to 30 °C, whereas long-chain PFAS were minimally affected. The Freundlich isotherm described all equilibrium adsorption data with a single parameter value of n = 0.5. The Langmuir model provided a good fit for all short-chain PFAS but failed to yield a consistent maximum adsorption capacity (qmax) at different temperatures. Extending Langmuir to the Frumkin isotherm provided a constant qmax and revealed that reduced short-chain PFAS adsorption at higher temperatures is due to increased lateral interactions between adsorbed molecules. Kinetic analysis showed that intraparticle diffusion coefficients increased with temperature, with stronger effects for short-chain PFAS. Using isotherm and kinetic parameters, breakthrough curve predictions showed that for short-chain PFAS, an increase in temperature from 10 to 30 °C reduced the number of treated bed volumes before breakthrough by a factor of 3, whereas long-chain PFAS remained unaffected. These findings highlight the importance of considering temperature effects in PFAS removal using activated carbon.This study investigated the adsorption of eight PFAS at 10, 20, and 30 °C.

They occur in small quantities within a complex organic matrix comprising a plethora of compounds. A robust quantification of the NP concentration thus requires the development of a comprehensive analytical workflow to handle potential interferents. Thermal desorption–proton-transfer reaction–mass spectrometry (TD-PTR-MS) creates the necessary chemical selectivity to distinguish NP signals from the organic matrix. Nevertheless, the recorded raw mass spectra are too complex for direct interpretation, and further signal clustering/scoring is required for a more in-depth analysis. Here, we resolved this problem in a novel workflow, which combines non-negative matrix factorization (NMF) and multivariate standard addition (MSA). This allows us to mathematically separate the NP’s signature from the mixture, as showcased for polystyrene nanoparticles. The method produces an unequivocal and matrix-corrected NP fingerprint for identification and quantification. MSA and NMF enabled us to quantify polystyrene NP in different environmental samples in the lower nanogram range. The mass concentration of polystyrene NP in Waal River water sampled close to Nijmegen, the Netherlands, was 4.7 ± 0.65 ng/mL and 39 ± 0.70 ng/g in sand samples from the river’s shore. A sand sample from a local playground in Nijmegen exhibited a higher concentration of 129 ± 1.1 ng/g.The proposed novel workflow is built on sensitive mass spectrometry and a machine learning approach to data interpretation that enables identification and precise quantification of nanoplastic concentrations in complex environmental samples.

Two input sets were considered: a full set containing comprehensive hydrochemical variables for high-accuracy prediction and a reduced on-site set including only field-measurable parameters and total arsenic, designed for rapid and cost-effective screening. Due to limited As(III) data, models were trained to estimate As(V) instead. Three algorithms: random forest (RF), support vector regression (SVR), and artificial neural network (ANN), were evaluated using 5-fold cross-validation. RF achieved the highest accuracy under the full set, while SVR showed the most robust performance across both input sets. ANN underperformed due to overfitting caused by a scarcity of high-concentration samples. Margin-based learning of SVR allowed the model to maintain stability despite fewer inputs, and outliers were included, suggesting its suitability for fast screening monitoring. The proposed SVR model can reduce arsenic speciation analysis costs by minimizing laboratory requirements while maintaining reliable accuracy, with only total As concentration required.

In this study, two stormwater ponds were studied during different hydrological conditions by means of a battery (n = 6) of cell-based bioassays, whereby the toxic pressure of the inlet and outlet water could be assessed. While no activities were observed for the oxidative stress reporter gene or androgenic activation or inhibition, clear agonistic and antagonistic estrogenic as well as aryl hydrocarbon activation responses were observed. Our observations further indicate that the efficiency of the ponds’ ability to lower this bioactivity from inlet to outlet was highly variable, with several cases where higher activity was observed in the outgoing water than in the ingoing water, indicating poor management of the stormwater and the need for improved treatment approaches before the stormwater is discharged into recipient water bodies.Stormwater ponds show inconsistent pollution reduction, with some increasing toxicity, emphasizing the need for improved stormwater treatment strategies.","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"5 9","pages":"5112–5121"},"PeriodicalIF":4.3,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/pdf/10.1021/acsestwater.5c00256","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145036354","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}
