While hydroxyl metabolites of polycyclic aromatic hydrocarbons (PAHs) are commonly used exposure biomarkers of combustion-originated air pollutants, methylated PAHs are more abundant in woodsmoke than other sources. Thus, urinary PAH carboxylic acids, which are metabolites of methylated PAHs, may serve as more sensitive biomarkers of wildfire exposure. In this exploratory study, we developed an LC-MS/MS method to simultaneously quantify hydroxylated and carboxylic metabolites of PAHs and methyl-PAHs in urine. This method was then applied to 56 urine samples collected from 8 campers before, during, and after a 4-hour exposure to campfire. Campers also wore silicone wristbands to monitor ambient PAHs. We found that 1-pyrenecarboxylic acid (1-PYRCA) levels increased significantly at 4 h (96.9%, 95% CI: 2.60-101%), 6 h (96.8%, 95% CI: 5.85-107%), and 8 h (92.5%, 95% CI: 3.59-99.2%), and returned to baseline levels at 24 h. In contrast, the campfire exposure did not significantly increase other urinary PAH metabolites. Wristband PAHs also significantly increased during the 4-hour exposure. These results suggest the use of urinary 1-PYRCA as a sensitive exposure biomarker for woodsmoke and potentially for assessing exposure to wildfires.</p>","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":" ","pages":""},"PeriodicalIF":8.8,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12439608/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145079060","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, over half of the road network in Canada consists of unpaved roads, which remain unstudied for 6PPD-Q contamination. In this paper, we hypothesize that (1) unpaved road networks can provide a pathway for 6PPD-Q to enter the environment and (2) 6PPD-Q concentrations in unpaved road dust are influenced by location, speed limit, collection date, and total organic carbon (TOC) content of the roads. To investigate this, we collected gravel from the surface of unpaved roads in and around Saskatoon, Saskatchewan, Canada. Chemical extractions of road dust allowed for the detection and quantification of 6PPD-Q within each sample. Concentrations of 6PPD-Q ranged between 0.207 and 1.47 ng/g of dw (median: 0.511 ng/g of dw). When normalized to TOC content, concentrations varied between 9.83 and 342 ng/g of TOC (median: 145 ng/g of TOC).

Therefore, alternative methods for assessing avian PFAS exposures are needed. Herein, we explore the utility of opportunistic sampling of building collision fatalities for expanding knowledge of PFAS exposures in wild birds. Concentrations of 40 PFAS of regulatory concern were measured in 50 livers from eight passerine species killed in building strikes during their migration through Chicago, IL. Results indicate that exposure is dominated by perfluoroalkyl carboxylic acids, fluorotelomer carboxylic acids, and perfluoroalkyl sulfonic acids and that physiological factors and feeding strategies may impact PFAS exposures. Comparing liver concentrations to those found in similar species at contaminated and noncontaminated sites indicates that PFAS levels detected in building collision fatalities are representative of levels found in wild populations, suggesting that this approach may circumvent challenges encountered in traditional bird biomonitoring studies and offer opportunities for more detailed study of factors governing PFAS exposure and bioaccumulation.</p>","PeriodicalId":37,"journal":{"name":"Environmental Science & Technology Letters Environ.","volume":"12 9","pages":"1232–1237"},"PeriodicalIF":8.8,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009742","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 present a data-driven strategy for unbiased sampling of candidate structures for NTA LC-HRMS method development from extensive chemical spaces, such as the U.S. EPA’s CompTox (>1 million chemicals). The workflow maximizes physicochemical/structural diversity using precomputed PubChem descriptors (e.g., molecular weight, XLogP) and grants LC-HRMS compatibility thanks to predicted mobility and ionization efficiency from molecular fingerprints. The resulting measurable compound lists (MCLs) provide broad, heterogeneous coverage for NTA method development, validation, and boundary assessment.
