This study examined air quality in three major East African cities─Kampala, Nairobi, and Dar es Salaam─by integrating low-cost air sensors with satellite data to produce 1 km × 1 km resolution daily PM2.5 (particulate matter smaller than 2.5 μm) maps from 2019 to 2023. Average PM2.5 concentrations were 31.4 ± 6.6 μg/m3 around Kampala, 21.7 ± 2.8 μg/m3 around Nairobi, and 33.1 ± 7.4 μg/m3 around Dar es Salaam, indicating moderate to unhealthy levels of air quality. Unexpectedly, urban centers exhibited lower PM2.5 levels than surrounding suburban area. This discrepancy is likely due to combustion-related activities that occur in the suburbs. Such results suggest that air quality mitigation efforts must extend beyond urban centers to suburban areas, where seasonal vegetation loss and combustion processes may drive pollution spikes. Beyond presenting a scalable approach for monitoring air quality in data-scarce regions, this study highlights the importance of localized strategies for urban air quality management.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"12 9","pages":"1169–1176"},"PeriodicalIF":8.8,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/pdf/10.1021/acs.estlett.5c00451","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009595","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}

It is imperative that the environmental health and safety community recalls previous efforts to integrate data surrounding engineered nanomaterials to serve as guidance for the next generation of materials. We therefore describe an international collaboration focused at the early stages in the informatics process, the data curation level. Our experiences are described in nine guidelines that can be adopted by future collaborations. These guidelines were written to be actionable and structured within scalable phases. Guidance is also provided on the necessary personnel roles that should be incorporated into funding plans for developing and using advanced materials.

However, aspiration of contaminated water─a known cause of aspiration pneumonia─is seldom modeled in L. pneumophila risk assessment. Here, we develop a quantitative microbial risk assessment model to estimate the risks associated with aspiration exposures. Monte Carlo simulations, incorporating the aspiration water volume, the aspiration frequency, and the alveolar deposition fraction, reveal that low L. pneumophila concentrations in water can yield an appreciable infection risk in populations prone to aspiration. Under equal L. pneumophila concentrations, we find that an aspiration event can pose a higher infection risk than aerosol inhalation from showers or faucets. Sensitivity analyses identify the aspiration volume as a driver of risk. Our findings highlight the need for risk management strategies that address not only aerosol generation but also the aspiration of contaminated water.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"12 7","pages":"785–791"},"PeriodicalIF":8.8,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144808920","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}

However, the key parameters governing the reactivity of RHS via the SET pathway remain unclear. This study comprehensively investigated the SET pathway of the RHS with 51 aromatic contaminants by quantum-chemical calculations. The calculated free energy changes of the SET pathway (ΔGaq,SETR) followed the order Cl• < Cl2•– < Br• < Br2•–, which was consistent with the order of their reduction potentials. However, the free energy of activation of the SET pathway (ΔGaq,SET⧧) followed a different order of Cl• < Br• < Cl2•– < Br2•–, which agreed with the order of their rate constants. This inconsistent trend between ΔGaq,SETR and ΔGaq,SET⧧ for RHS reactions was attributed to the difference in reorganization energy, which is essentially related to the vertical electron affinity and radius of RHS. Therefore, the rate constants of SET reactions of RHS depend not only on their reduction potential but also on their vertical electron affinity and radius. These findings unravel the key factors determining the reactivity of RHS via the SET pathway and have profound implications for understanding other SET processes in water.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"12 6","pages":"761–767 761–767"},"PeriodicalIF":8.9,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144238352","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}

This study investigated the compositions, formation pathways, and sources of OSs at a coastal site of the South China Sea in summer. Thirty-three OS species were quantified by using an UHPLC-Orbitrap MS and were assessed under marine and terrestrial air mass origins. iOSs (isoprene-derived OSs) ranked the highest, followed by C2/C3 OSs (OSs with two or three carbon atoms). The formation of iOSs was influenced by aerosol pH and their major precursor (isoprene), with photochemical processes playing a significant role in terrestrial transport. Different from urban conditions, sea breezes favored the formation of 2-MAS (C4H7O7S–) over 2-MTS (C5H11O7S–) even under low NOx levels, mainly attributed to the high temperature and dominance of aqueous oxidation. Compared to terrestrial transport, the formation of C2/C3 OSs was more favored than that of iOSs under the influence of sea breezes. Marine biogenic emission was quantified as an important source of C2/C3 OSs. This study enhances our understanding of the influence of both terrestrial and marine factors on the formation pathways of atmospheric OSs and emphasizes the significant contribution of marine biogenic sources to OSs.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"12 6","pages":"739–746 739–746"},"PeriodicalIF":8.9,"publicationDate":"2025-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144238734","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}

Wastewater-based surveillance (WBS) offers a noninvasive and community-level approach to monitoring the circulation of pathogens, including the measles virus. Here, we retrospectively applied a duplex digital PCR assay to distinguish between wild-type and vaccine strains of the measles virus in wastewater samples available from an existing national WBS program. Samples originated from the wastewater treatment plant serving the Lausanne city catchment area, where an outbreak occurred before spreading to the broader Canton Vaud region. Despite high vaccination rates, viral loads of the measles wild type were detected during the first transmission event involving 21 cases identified within a week. However, viral loads were no longer detectable after the initial 21 cases, despite an additional 30 cases reported in the following 3 weeks, possibly due to lower incidence rate or location outside the catchment. Measles vaccine strain was not detected during the outbreak. Our results demonstrate the complementarity of WBS with clinical surveillance and suggest its potential as an early warning system for measles and other vaccine-preventable diseases. Further improvements in the assay sensitivity and integration with epidemiological data could enhance the utility of WBS for outbreak detection and control.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"12 6","pages":"689–694 689–694"},"PeriodicalIF":8.9,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acs.estlett.5c00244","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144238504","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}
