In this study, we utilized a plunging water jet in a controlled laboratory setup to generate SSA. We investigated the enrichment process of PFAAs on nascent SSA by systematically varying three key parameters: 1) total organic carbon (TOC), 2) water jet flow rate, and 3) inorganic ion composition. The results showed a significant enhancement in enrichment when organic matter was introduced into artificial seawater. However, this enhancement did not exhibit a consistent trend when increasing the TOC from 1 to 2 mg L–1. The enrichment was increased at higher water jet flow rates (3.2 L min–1) compared to lower flow rates (1.6 and 2.4 L min–1), and the effect was particularly pronounced for submicrometer SSA particles. There was minimal difference in the enrichment of PFAAs when SSA was generated using sodium chloride solution instead of artificial seawater at the same salinity. Overall, these findings shed light on the complex process of PFAA enrichment on SSA and improved our understanding of the uncertainties associated with varying dissolved organic matter, water jet flow rate, and inorganic ion composition.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"11 7","pages":"746–751"},"PeriodicalIF":8.9,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acs.estlett.4c00287","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141255771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

To overcome the rate-limiting charge transfer kinetics and weak ion adsorption tendency, a metal–organic framework (MOF)-derived hybrid electrode with an exceptional flow capacitive deionization performance is reported here. Using MIL-88(FeNi) as a sacrificial template, we synthesized a porous graphitic framework decorated with nanosized spinel NiFe2O4 (NiFe2O4@PC-500) electrodes, maintaining a parent rod-shaped morphology with a large surface area of 1227 m2/g. The synergistic interaction of NiFe2O4 nanoparticles with the mesoporous graphitic framework exhibited remarkable desalination performance with a salt adsorption capacity of ∼34 mg/g and ∼89% salt removal at 1.2 V, surpassing those of traditional carbon-based electrodes. Moreover, NiFe2O4@PC-500 maintained its desalination capacity and structural integrity over prolonged desalination cycles with a specific capacitance of ∼206 F/g and capacitive retention over 500 cycles. This study presents a universal approach for strategically implementing MOF-derived heterostructures as potent flow electrode materials.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"11 6","pages":"640–647"},"PeriodicalIF":10.9,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141197912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

We found that the annual discharge of excess Gd and La in a treatment area positively correlated with the number of hospitals in that area. The excess Gd concentration in the treated water increased by an order of magnitude late at night Monday, whereas the excess La concentration remained constant. Sequential extraction experiments on sewage sludge revealed that excess La is predominantly incorporated in phosphate, not silicate, as in zeolite catalysts. We identified lanthanum carbonate tablets (e.g., Fosrenol), prescribed daily to kidney patients to prevent hyperphosphatemia, as the source of excess La. Due to its low solubility, most of the anthropogenic lanthanum settles as sewage sludge in WWTPs, and only a small percentage is released into treated water.

We found QACs in human feces at total concentrations (∑All) ranging from 170 to 8270 ng/g dry weight (dw) (median: 746 ng/g dw). BACs were dominant among the four classes of QACs analyzed, accounting for 49% of ∑All, followed by DDACs (40%), BACm (9%), and ATMACs (2%). In urine, only ω-carboxyl (COOH−) metabolites of BACs were frequently found, with a median concentration of ∑BACm at 0.49 ng/mL. QACs measured in human feces exhibited positive correlations, suggestive of the usage of these chemicals as a mixture. The cumulative daily intakes (CDIs) were calculated based on QAC concentrations measured in feces, through a reverse dosimetry approach. The average CDI of QACs was estimated to be 551 ng/kg body weight (BW)/day for adults, which was 3 orders of magnitude below the toxicity reference dose (RfD) suggested for BACs (0.44 mg/kg BW/day) and DDACs (0.1 mg/kg BW/day).

Given the need to better understand EtO emissions and associated health effects, it is imperative to overcome the significant challenges associated with EtO measurement in complex air matrices such as combustion emissions. This work focused on addressing these challenges by evaluating the utility of widely used canister-based EtO ambient measurement approaches, EPA Methods TO-15 and TO-15A, to investigate the presence of EtO in heavy-duty diesel vehicle (HDDV) exhaust. Chassis dynamometer testing was performed on two HDDVs and emissions samples were collected and analyzed following TO-15/TO-15A. Initial testing utilizing TO-15 led to the identification of a diesel exhaust constituent, ethyl nitrite, that coeluted with EtO during analysis and contributed a large positive bias. An optimized TO-15A analytical approach was developed and utilized to measure EtO in diesel exhaust from two HDDVs in additional dynamometer tests. Using this optimized approach, EtO was not detected in the HDDV exhaust in these tests. This work highlights the importance of utilizing this optimized approach to accurately quantify EtO in mobile source exhaust and may also be needed for testing other combustion sources.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"11 6","pages":"560–565"},"PeriodicalIF":10.9,"publicationDate":"2024-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141165408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Using the BETR-Global model and historical emission estimates, we simulate the global dispersion of CPs from 1930 to 2020. Whereas contamination trends in the main contaminated regions (East Asia, Europe, North America, and South Asia) diverge, CP concentrations in the Arctic, Antarctica, and the Tibetan Plateau all increase. By 2020, East Asian, European, and North American emissions contributed 38%, 26%, and 18% of CP contamination in the High Arctic, respectively, while Southern hemispheric emissions and emissions around the Tibetan Plateau primarily contribute to CP contamination in central Antarctica and on the Plateau, respectively. Our results emphasize the important contribution of (i) European and North American emissions to historical CP contamination in remote regions and current MCCP and LCCP contamination in the High Arctic and (ii) East Asian emission to current SCCP and MCCP contamination of all three remote regions.

Long-chain sphingolipids (C20CER) were negatively associated with levels of PFRs, PFAS, and BPs, while C12CER and C14CER (short-chain) were positively associated with levels of PFRs and BPs. Furthermore, we observed an overall negative association between ∑7PFRs and endogenous biocomponents but a positive dose–effect relationship with ∑5BPs and biocomponents using Bayesian kernel machine regression models. Among the biocomponents, C20CER and C14CER contributed the most to the negative and positive associations, respectively. Specifically, a change in Ln C20CER (Z-score) concentration from the 25th to 75th percentile was associated with a decrease in ∑7PFRs of 47.0%-SD (−61.8%, −32.3%) when other biocomponents were at their median values.
