A key consideration for communities pursuing water reuse is understanding the amount of treatment that is needed to ensure adequate human health protection. Several U.S. EPA documents describe the importance of managing acute microbial risks and highlight the utility of quantitative microbial risk assessment for developing \"fit-for-purpose\" treatment targets based on the source of water and end-use. However, there are no U.S. federal water reuse regulations and states are currently considering microbial treatment targets for various applications. Previous publications have yet to address this need by using an updated and consistent set of input parameters to present risk-based microbial treatment targets across a wide range of sources of water, end-use applications, and health benchmarks. This work combines the most current modeling inputs and dose-response parameter values to provide probability of infection and disease burden-based microbial treatment targets for untreated municipal wastewater, untreated onsite wastewater, graywater, stormwater, and roof runoff water used for potable reuse, indoor nonpotable use, and landscape irrigation applications.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"11 11","pages":"1175-1181"},"PeriodicalIF":8.9,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11770559/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143057407","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}

However, direct evidence of the spatial distribution of trace metals within the organo-mineral soil architecture is lacking, though this knowledge is important to better predict the fate of trace metals in ecosystems. Here, we present a spectromicroscopic approach to map the distribution of Zn and Cd between mineral phases and organic matter at a resolution of approximately 150 nm. This was achieved using nanoscale secondary ion mass spectrometry (NanoSIMS) applied to a spiked gradient of Zn and Cd concentrations in an arable soil. We observed patchy-distributed Zn and Cd hotspots in all soils, including at a native concentration in the nonspiked soil. With increasing Zn and Cd spikes, these metals preferentially colocated with Fe-dominated mineral phases, whereas with the highest spike, Zn and Cd increasingly colocated with clay minerals and soil organic matter. Soil extracts suggested that large proportions of spiked Zn and Cd were tightly bound to the colocated phases. Our direct measurements of patchy-distributed Zn and Cd hotspots indicate that distinct soil surfaces preferentially allocate and govern the fate of trace metals in soils.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"12 3","pages":"313–319 313–319"},"PeriodicalIF":8.9,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acs.estlett.4c00401","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143591171","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}

This study estimated NF3 emissions and their spatial distribution in China from 2017 to 2021 based on atmospheric observations from nine background stations in China, by employing a Lagrangian-dispersion-model-based Bayesian inversion technique. We found that NF3 emissions in China increased from 0.95 (0.82–1.07) Gg yr–1 in 2017 to 1.41 (1.28–1.55) Gg yr–1 in 2021, representing a substantial growth of 48% over this period. The absolute increase in NF3 emissions in China over 2017–2020, 0.65 (0.57–0.74) Gg yr–1is comparable to the increase in global emissions (0.63 (0.50–0.75) Gg yr–1) over the same period. We identified substantial NF3 emissions in the Pearl and Yangtze River Delta regions and Hubei Province, where well-established semiconductor industries could have contributed to NF3 emissions. Moreover, large NF3 emissions were identified in northern China, including Hebei, Henan, and Shandong Provinces. If control measures are not implemented, increasing NF3 emissions may delay China’s progress toward achieving its carbon neutrality target by 2060.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"11 10","pages":"1096–1102 1096–1102"},"PeriodicalIF":8.9,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142403339","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}

The effects of methanol and other frequently used carrier solvents on the chlorination rates of aromatic precursors of disinfection byproducts during water chlorination were investigated. At concentrations as low as 0.50 vol %, methanol increased chlorination rates of ethylparaben, phenol, 4-hydroxybenzoic acid, ethyl 3-hydroxybenzoate, and ethyl 2-hydroxybenzoate. Methanol did not increase the chlorination rates of salicylic acid, dimethenamid, or 1,2-dimethoxybenzene. Ethylparaben and phenol chlorination were especially sensitive to methanol, with pseudo-first-order rate constants (kobs) increasing by a factor of >2 in water containing 2.0 vol % methanol compared to those in methanol-free controls. Rate enhancements persisted across differing reaction conditions (pH 6–10 and in buffers containing borate or phosphate). The rate enhancements of unsubstituted and para-substituted phenols were larger than those of meta- and ortho-substituted phenols. The carrier solvents acetone, acetonitrile, and tert-butanol had no appreciable impact on the chlorination rates of ethylparaben. Overall, our findings suggest that methanol as a carrier solvent can cause systematic errors in lab-scale chlorination experiments. To avoid experimental artifacts, researchers should prepare stock solutions in water (when feasible) or minimize carrier solvent concentrations present in reaction solutions.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"11 10","pages":"1110–1115 1110–1115"},"PeriodicalIF":8.9,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142402866","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 thus analyzed total Hg (THg) in muscle, liver, and kidney tissues of oviparous Galeus melastomus catsharks and their embryos, which aggregate in vast numbers near deep-sea brine pools in the southeastern Mediterranean Sea. These Hg-rich brines (≤238 ng L–1) are a likely liable geogenic Hg source in this nursery. Shark tissues carried substantial THg [2.7 μg (g of wet weight)−1, median], and extreme values were found in kidneys [≤26.7 μg (g of wet weight)−1], likely due to environmental uptake. Increased THg in embryos [0.64 ± 0.31 μg (g of wet weight)−1] implies substantial maternal offloading (∼20%).

Variations in the light-absorption properties and molecular composition of BrC due to atmospheric photochemical aging process have not been well constrained, leading to high uncertainty in evaluating its global radiative effect. The molecular composition of atmospheric BrC were investigated to stress the BrC photobleaching in this work. In total, 896 organic compounds were identified, which accounted for 2.5%–26.1% of organic aerosol in mass concentration. We found that solar radiation led to the declined mass absorption coefficient at 375 nm (MAC375), indicating BrC photobleaching, coinciding with an elevated mass fraction of carboxylic acids (CAs). This phenomenon was more pronounced under higher-energy solar radiation. Specifically, the mass fraction of nitrocarboxylic acids (NCAs) in CAs increased during BrC photobleaching, which was potentially caused by the oxidation of nitrophenols, resulting in an ∼83.3% decrease in MAC375.

CH4 flux was measured in urban Beijing using the eddy covariance method during a summer campaign. With a mean of 152.6 ± 107.9 nmol/m2/s, the CH4 flux was estimated to depend little on the intensity of human activities, with minimal influence from biogenic sources. Emission hotspots with large temporal variability were identified in the study fetch area, which increased the mean CH4 flux by 12.5%. Based on the lack of large, known biogenic sources in nonhotspot (background) areas, we attributed the CH4 flux in these areas (135.6 ± 70.56 nmol/m2/s) mainly to natural gas. Thus, we estimate as an upper limit that natural gas contributes 88.9% to the total CH4 flux in urban Beijing. However, poor alignment between the dominant sources in the inventories and the characteristics of the measured CH4 flux were observed, suggesting substantial underestimation of emissions from natural gas sources in the inventories.

However, past monitoring data are often limited in scope and number of chemicals, while suitable sample types are not always available for remeasurement. Data-driven cheminformatics methods for patent and literature data offer several opportunities to fill this gap. The chemical stripes were developed as an interactive, open source tool for visualizing patent and literature trends over time, inspired by the global warming and biodiversity stripes. This paper details the underlying code and data sets behind the visualization, with a major focus on the patent data sourced from PubChem, including patent origins, uses, and countries. Overall trends and specific examples are investigated in greater detail to explore both the promise and caveats that such data offer in assessing the trends and patterns of chemical patents over time and across different geographic regions. Despite a number of potential artifacts associated with patent data extraction, the integration of cheminformatics, statistical analysis, and data visualization tools can help generate valuable insights that can both illuminate the chemical past and potentially serve toward an early warning system for the future.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"11 10","pages":"1046–1052 1046–1052"},"PeriodicalIF":8.9,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acs.estlett.4c00560","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142403264","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}
