This study examines the occurrence of trace elements (TEs) and Sr isotope (87Sr/86Sr) variations in phosphate rocks and mineral fertilizers from a sample collection representative of major phosphate producing countries. We show high concentrations of several TEs in phosphate rocks (n = 76) and their selective enrichment in phosphate fertilizers (n = 40) of specific origin. Consistent with the concentrations in parent phosphate rocks, phosphate fertilizers from the U.S. and Middle East have substantially higher concentrations of U, Cd, Cr, V, and Mo than those in fertilizers from China and India. Yet, fertilizers from China and India generally have higher concentrations of As. The 87Sr/86Sr in phosphate fertilizers directly mimic the composition of their source phosphate rocks, with distinctive higher ratios in fertilizers from China and India (0.70955–0.71939) relative to phosphate fertilizers from U.S. and Middle East (0.70748–0.70888). Potash fertilizers have less Sr and TEs and higher 87Sr/86Sr (0.72017–0.79016), causing higher 87Sr/86Sr in mixed NPK-fertilizers. Selective extraction (Mehlich III) of soils from an experimental agricultural site shows relative enrichment of potentially plant-available P, Sr, and TEs in topsoil, which is associated with Sr isotope variation toward the 87Sr/86Sr of the local utilized phosphate fertilizer.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":null,"pages":null},"PeriodicalIF":10.9,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140942497","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}

Understanding bidirectional risk transmission (global-to-local and local-to-global) in P supply and consumption chains is thus essential. Ignoring P system interdependencies and associated risks could have major impacts on critical infrastructure operations and increase the vulnerability of global food systems. We highlight recent unanticipated events and cascading effects that have impacted P markets globally. We discuss the need to account for exogenous shocks in local assessments of P flows, policies, and infrastructure design choices. We also provide examples of how accounting for undervalued global risks to the P industry can hasten the transition to a sustainable P future. For example, leveraging internal P recycling loops, improving plant P use efficiency, and utilizing legacy soil P all enhance system resiliency in the face of exogenous shocks and long-term anticipated threats. Strategies applied at the local level, which are embedded within national and global policy systems, can have global-scale impacts in derisking the P supply chain.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":null,"pages":null},"PeriodicalIF":10.9,"publicationDate":"2024-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acs.estlett.4c00208","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140889263","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}

Additionally, we examined the chemical profiles of deep ocean biota inhabiting the SCB to assess the bioavailability of DDT+ and HOCs to the deep ocean food web. We detected 49 HOCs across all samples, including 15 DDT+ compounds in the sediment and 10 DDT+ compounds in the biota. Compounds included tris(4-chlorophenyl)methane (TCPM) and its isomers and three unknown DDT-related compounds previously identified in marine mammals. No clear trends were identified regarding DDT+ distribution in sediments. High DDT+ body burdens were found in biota irrespective of collection location, indicating widespread DDT+ contamination in the deep ocean of the SCB. TCPMs were detected in all biota samples except a single surface species, indicating that deep ocean sediment may be a source of DDT+ to the marine food web.

HRP, with energy flux units [KJ m–2 s–1], is a metric calculated from both the physical and chemical properties of the hyporheic zone. We apply the HRP framework for iron reactions, using existing geochemical and geophysical data from two metal-impacted alpine streams at high and low flow. In these two systems, HRP delineates contrasting controls on iron fate and transport with biogeochemical controls in Mineral Creek and physical controls in Cement Creek. In both systems, HRP scales with discharge and hyporheic-zone extent as flows change seasonally, which demonstrates the ability of HRP to capture physical aspects of chemical reactions in the hyporheic zone. This paper provides a foundation on which HRP can be expanded to other solutes where chemical gradients in the hyporheic zone control reaction networks, making it broadly applicable to redox cycling in stream systems. This framework is useful in quantifying the role of the hyporheic zone in sourcing and storing metal(loid)s under varying hydrologic conditions with implications for water quality, mine remediation, and regional watershed management.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":null,"pages":null},"PeriodicalIF":10.9,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acs.estlett.4c00035","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140889250","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, there remains a knowledge gap regarding the dynamic changes in reactivity and toxicity during the decay process of EPFRs emitted from incomplete solid fuel burning, which are identified as a primary source of EPFRs. Here, we report the decay behavior of EPFRs in particulate matter (PM) emitted from typical solid fuel burning and the associated ROS generation and cytotoxic effects. The EPFRs in freshly produced PM first undergo rapid exponential decay with lifetimes ranging from 15 to 97 h and are categorized as fast-decay EPFRs. The relative content of fast-decay EPFRs was 40.5 ± 15.3%, while the remaining portion, defined as slow-decay EPFRs, displayed an extremely slow rate of decay. ROS generation and cytotoxicity decreased by 38.8 ± 11.4% and 62.5 ± 12.6%, respectively, following the depletion of fast-decay EPFRs, which were further demonstrated to be responsible for the variations in PM reactivity and toxicity. These new findings underscore the importance of considering the decay process of EPFRs in assessments of PM toxicity.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":null,"pages":null},"PeriodicalIF":10.9,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140827739","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}

Here submicron aerosol composition in a basement gym was characterized by a high-resolution aerosol mass spectrometer.

Positive matrix factorization identified two distinct gym-related OA factors, i.e., siloxane OA (SiOA) and cigarette smoke OA (CSOA). Unexpectedly high concentrations of particulate siloxane, up to 6 μg m–3 and contributing 7–11% of OA were observed, and the variations of SiOA were strongly correlated with carbon dioxide emissions from human activities. The source of SiOA is likely from the lubricant of silicone polymers used in fitness equipment during exercise. Additionally, the presence of CSOA in the gym, on average contributing 6–7% of OA, is primarily linked to outdoor transport during ventilation. Our results highlight the significance of thorough investigations of air quality across different gyms with varying equipment, human occupancy, and ventilation conditions which is pivotal for implementing effective measures that ensure healthy indoor air quality and minimize potential health risks associated with exercise in gyms.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":null,"pages":null},"PeriodicalIF":10.9,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140827557","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}

In this study, Daphnia magna was exposed to fibrous and fragmentary MPs at concentrations ranging from 1 to 1000 items/mL for 7 days. The results revealed that fibrous MPs tended to entangle with the second antennae and tail claws of D. magna, whereas fragmentary MPs merely adhered to the surface of the daphnids but do not exhibit entanglement. Additionally, the swimming speed and projected area of swimming trajectories of daphnids significantly decreased in the 100 items/mL group compared with the control. However, the occurrence of entanglement and slow swimming was less pronounced in the 1000 items/mL group due to the aggregation of fibrous MPs. Scanning electron microscopy revealed that D. magna possessed a rich spine structure on the surface of their bodies, particularly on their antennae and tails. The entanglement of D. magna by fibrous MPs resembled the action of manufactured “hook and loop”. Overall, the results of this research revealed that entanglement is observed in small animals exposed to fibrous MPs, highlighting the direct biological effects of MPs beyond ingestion.","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":null,"pages":null},"PeriodicalIF":10.9,"publicationDate":"2024-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acs.estlett.4c00279","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140827651","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 review reflects discussion and insights gained during and after this workshop and summarizes key signs of progress in science and policy, ongoing critical issues to be addressed, and possible ways forward. Some key take home messages include: 1) understanding of human health effects continues to develop dramatically, 2) regulatory guidelines continue to drop, 3) better understanding of emissions and contamination levels is needed in more parts of the world, 4) analytical methods, while improving, still only cover around 50 PFASs, and 5) discussions of how to group PFASs for regulation (including subgroupings) have gathered momentum with several jurisdictions proposing restricting a large proportion of PFAS uses.
