Daily fire detections from the Moderate Resolution Imaging Spectroradiometer (MODIS) were clustered using density-based methods to identify persistent burning within 5 km of bases. Validation was conducted using military imagery and Google Earth. A sensitivity analysis compared MODIS fire detections to those from the newer Visible Infrared Imaging Spectroradiometer (VIIRS) at a civilian burn pit in Djibouti. MODIS detected 285,810 fires in Iraq and 3702 in Afghanistan. Clustering identified 398 bases in Iraq and 122 in Afghanistan with burning nearby. In Iraq, persistent clusters were linked to oil and gas flares, while smaller clusters on bases in both countries were consistent with burn pits. MODIS and VIIRS both detected the Djibouti burn pit, but VIIRS recorded three times more fire detections, highlighting its sensitivity in detecting biomass and waste burning.","PeriodicalId":15684,"journal":{"name":"Journal of Exposure Science and Environmental Epidemiology","volume":"36 5","pages":"834-844"},"PeriodicalIF":5.9,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12637216/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145276944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some methods assume smaller population pools and often lack the statistical power of inferences. Other methods are designed for larger population pools and cannot be downscaled to accommodate the details of microenvironments, such as a gym or cafeteria. Moreover, typically, individuals have a relatively small circle of friends, family, and co-workers with whom most contacts are taking place, while the external contacts occur sporadically, rendering the population clustered. Practicable infection risk assessment models should account for population size, geometry and occupancy of public places, behavioral and professional patterns that define daily routines, and societal structure. We describe a novel methodology and investigate effects of the population social structure, along with other local constraints, on infection outbreak dynamics. The study is based on the recently developed stochastic microexposure model (S-MEM). The model has been generalized to describe clustered populations. The methodology is demonstrated for a generic community of several thousand students living on campus. The student population possesses a natural social structure of being clustered into classes. The results indicate that the social structure has the first order effect on the spread of the infection. Depending on the number, size, and degree of inner- and outer-cluster connections, the outbreak exhibits distinct durations, power, and multiple peaks of infection. Moreover, the contribution of different microenvironments to infection risk evolves during the course of the outbreak.","PeriodicalId":15684,"journal":{"name":"Journal of Exposure Science and Environmental Epidemiology","volume":"36 2","pages":"386-397"},"PeriodicalIF":4.7,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145226579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a need for an aggregate PFAS exposure measure due to the increasing diversity of structures. Aggregate measures are important for informing clinical care, biomonitoring, and research standardization. Current approaches for human biomonitoring of PFAS include targeting and quantifying a limited number of molecules and estimating exposure based on summed concentrations or statistical modeling. Extractable organofluorine (EOF) has been proposed as an aggregate PFAS biomarker that quantifies the total organically bound fluorine in a sample, encompassing PFAS regardless of knowing the exact chemical structures. However, EOF in human biomonitoring studies or environmental epidemiology is limited. The objective of this study is to comprehensively assess human studies that measure EOF and target PFAS in the same sample by conducting a literature search, data extraction, and secondary data analysis. We assessed the correlation of three aggregate PFAS exposure metrics with each other: EOF, adjusted summed concentrations of PFAS identified by the National Academies of Science Engineering and Medicine (NASEM), and PFAS burden scores. Across 8 published studies from US, Asia and Europe with 163 samples, EOF concentrations were higher than NASEM summed PFAS concentrations, and EOF was strongly associated with PFAS burden scores and NASEM sum. EOF does not identify or differentiate non-PFAS sources of fluorine which limits identification of individual molecules and their potential toxicity. Correlations between EOF, summed targeted PFAS concentrations, and PFAS burden scores demonstrated that EOF is a practical tool for estimating PFAS exposure and identifying individuals with high exposure to PFAS. Thus, EOF could be utilized for identifying individuals or sub-populations with high aggregate PFAS exposure. Practical considerations in laboratory analyses, including instrumentation, sample matrix, and sample extraction procedure, remain potential barriers to widespread implementation of EOF as a biomonitoring tool.","PeriodicalId":15684,"journal":{"name":"Journal of Exposure Science and Environmental Epidemiology","volume":"35 6","pages":"1020-1029"},"PeriodicalIF":4.7,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41370-025-00806-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145215494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PFAS are generally persistent, widely distributed in environmental media, and linked to various adverse health effects. The primary pathway of PFAS exposure to impacted communities is through contaminated drinking water. While many studies have demonstrated exposures from contaminated drinking water in such communities, less is known about the contribution of exposure from sources within the residential environment. Measurement data on the nature and level of PFAS in house dust, indoor surfaces, indoor air, soil and wristbands are required to identify and understand important pathways for human exposure. In this study, we collected house dust, surface wipe, indoor air, wristband, and soil samples at homes recruited from two communities previously impacted by drinking water contamination, one in Massachusetts and one in Delaware. At every home (n = 79), a floor dust sample was collected, while in a subset of homes (n = 28), more extensive environmental sampling was conducted. All samples collected were analyzed for up to 70 PFAS depending on the sample type. PFAS were found in all types of household samples, with 30 different PFAS detected in ≥50% of homes for at least one sample type. Vacuum dust, floor dust and soil had the highest detection rates across most PFAS. However, certain PFAS precursors were more prevalent in surface wipes, indoor air, and wristbands (e.g., FTOHs, FOSEs, FOSAs). diPAPs were widely detected across all sample types and had the highest concentrations among all analytes in dust, surface wipes and wristbands. A comparative analysis between the two sampling sites highlighted significant differences in PFAS profiles, with Delaware exhibiting higher levels of PFAAs in dust and soil, while Massachusetts showed greater concentrations of diPAPs across various media sampled. These findings highlight the widespread presence of PFAS in the residential environment, and the need for mitigation strategies that address both legacy compounds and emerging precursors across numerous media.","PeriodicalId":15684,"journal":{"name":"Journal of Exposure Science and Environmental Epidemiology","volume":"35 6","pages":"1050-1059"},"PeriodicalIF":4.7,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41370-025-00805-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145215488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Phase 1, we summarized major conclusions from eight authoritative sources across ~15 health hazard categories for 22 chemicals potentially related to the train derailment and response. In Phase 2, we conducted targeted literature searches in PubMed for higher-priority chemicals and outcomes with research gaps, considering the recency of authoritative reviews. Finally, we summarized findings from the retrieved studies and those from authoritative reviews to further characterize evidence gaps and the next steps. Eight higher-priority chemicals were skin and eye irritants, seven of which were also respiratory irritants, consistent with symptoms reported by East Palestine residents and workers. Five chemicals were human or animal carcinogens; two may cause adverse immunological or neurological effects, and one may cause damage to reproductive organs or the developing fetus. Vinyl chloride had the most comprehensive data. After Phase 2 literature searches, we suggested the need for primary studies for 12 chemical outcome pairs and a systematic review for two pairs.

We fit a random effects model to obtain the overall pooled effect and for stratified analyses examining biomarker sample type and timing, study confidence, scaling factors, and country of study origin. We also conducted a meta-regression to assess the impact of gestational age and other factors on the overall pooled effect. We found a 30-gram BW deficit (β = −30.3 g; 95%CI: −41.6, −18.9) with each ln-unit PFOS increase based on 53 studies identified in the systematic literature review. We detected BW deficits across all study confidence levels (β range: −27 to −37 g per ln-unit increase) with the largest deficit in the medium confidence grouping (β = −36.6 g; 95%CI: −56.3, −16.8). We did not see evidence of a gradient of BW deficits across biomarker sample timing (β range: −24 to −39 g per ln-unit increase), but the smallest deficit in our primary analyses was detected for the 18 early sample timing studies (β = −23.6 g; 95%CI: −38.7, −8.6). Robust deficits were also seen across various subgroups including by geographical region of study origin (e.g., Asian studies), more restrictive early biomarker sample collection, and post-partum samples (β range: −16.9 to −30.6 g). For meta-regression analyses, none of the investigated factors explained significant heterogeneity across studies. We detected a statistically significant BW deficit of 30 grams per each ln-unit PFOS increase across all 53 studies in our meta-analysis; results were comparable in magnitude across study confidence, sample timing, and other strata.
