To examine the association between pre- and postnatal urinary phthalates and bisphenols, and allergic conditions, and potential effect modification by sex, in pre-school children, through a pooled analysis. We pooled data from the Barwon Infant Study (Australia), the Canadian Healthy Infant Longitudinal Development Study (Canada), the Health Outcomes and Measures of the Environment (United States) and the Environmental Influences on Child Health Outcomes–wide cohorts (United States). Urinary phthalates and bisphenols were measured during pregnancy and early childhood. We estimated daily intakes from urinary concentrations, except for mono-(3-carboxypropyl) phthalate (MCPP). Outcomes, including asthma, wheeze, eczema, and rhinitis, were assessed up to five years of age through questionnaires and clinical assessments. We used generalised estimating equations for single compounds and quantile G-computation for the chemical mixtures. 5306 children were included. A two-fold increase in prenatal dibutyl phthalates (DBP; risk ratio [RR] = 1.08; 95% confidence interval [CI]: 1.00–1.16) and benzyl butyl phthalate (BBzP; RR = 1.06; 95%CI: 1.00–1.12) increased the risk of asthma in children under five.

Exposure to melamine and aromatic amines (AAs) is ubiquitous among pregnant people. However, studies investigating the maternal and fetal health effects of prenatal exposure are limited. This cross-sectional study aimed to (1) evaluate relationships between exposure to aromatic amines, melamine and its derivatives, and gestational diabetes in a pregnancy cohort in San Francisco, California, USA, (2) explore if non-chemical stressors modify these relationships, and (3) assess fetal sex differences using stratification. We measured 36 AAs, melamine, and three of its derivatives in second-trimester urine samples (n = 607). Financial strain and psychosocial stress were assessed using self-reported questionnaires. GDM status was abstracted from medical records. We used unadjusted and adjusted logistic regression models to calculate the odds of GDM associated with an interquartile range increase in urinary concentrations of melamine and AAs or higher levels of non-chemical stress, overall and stratified by infant sex. Interaction terms between each chemical and non-chemical stressor were used to test for effect modification. Eight analytes were detected in >65% of participants, with 100% detection of melamine and cyanuric acid. Among male infants, summed urinary concentrations of melamine and its analogs and o-Anisidine were associated with increased odds of GDM (OR: 1.08 [1.00, 1.17], OR: 1.18 [1.03, 1.36], respectively). Higher levels of perceived stress and discrimination were also associated with increased odds of GDM (OR: 1.41 [0.73, 2.70], OR: 2.33 [1.16, 4.67], respectively). We found limited evidence of interaction between chemical and non-chemical stressors. This study revealed positive associations between melamine and its analogs, some aromatic amines, and gestational diabetes, especially among pregnant women carrying male fetuses.

However, sources remained unidentified. To measure urinary 87Sr/86Sr isotope ratio in EXPERIVA participants, assess its reliability, and explore how its variance fluctuates based on Sr concentrations in biological (urine, hair, nails) and environmental (tap water) samples, as well as the density/proximity of unconventional oil and gas wells around participants’ residence. Participants provided urine daily over seven consecutive days. We measured 87Sr/86Sr in each urine sample from 7 participants and in pooled daily samples for all 75 participants. We used serial measurements to determine the intraclass correlation coefficient (ICC). We calculated the density/proximity of unconventional oil and gas wells around participants’ homes using inverse distance weighting (IDW). We assessed the variance of urinary 87Sr/86Sr based on Sr concentrations in biological/environmental samples and IDW through visual inspection and Levene’s test. We also performed unsupervised clustering to explore whether certain characteristics of the participants may be associated with a specific 87Sr/86Sr signature. Urinary 87Sr/86Sr ranged from 0.70798 to 0.71437. The ICC was 0.797 (95% CI: 0.574–0.953), indicating moderate to excellent reliability. Increasing Sr concentrations in hair were marginally associated with a decrease in urinary 87Sr/86Sr variance (p = 0.066). A similar but less consistent association was observed with increasing IDW. We observed no association between Sr concentrations in water and variance in urinary 87Sr/86Sr. No clear pattern was found using unsupervised clustering. To our knowledge, this study is the first to explore the use of urinary 87Sr/86Sr isotope ratios to investigate sources of Sr exposure. Results are consistent with the hypothesis that a predominant source contributes to Sr exposure in most exposed EXPERIVA participants, but the contribution of unconventional oil and gas wells around participants’ residences remains unclear. Findings should be considered as exploratory given the many limitations of this study. Our effort will hopefully benefit future studies aimed at identifying the sources of exposure in human populations.","PeriodicalId":15684,"journal":{"name":"Journal of Exposure Science and Environmental Epidemiology","volume":"36 5","pages":"827-833"},"PeriodicalIF":5.9,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41370-025-00784-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144334814","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}

The objective of this evaluation was to provide a contemporary review of exposure to VAM via residual VAM (co)polymer in a range of consumer products in the United States. The study authors conducted a market-basket sampling of residual VAM levels in 71 consumer products purchased in the United States that met the selection criteria. Subsequently, exposure assessments were conducted using ConsExpo (version 1.1.1) and the United States Environmental Protection Agency’s Consumer Exposure Model (CEM; version 2.1) on a subset of those identified products. Of the products analyzed, 40 had VAM concentrations below the lowest detection limits (0.1–2 ppmw), 19 were non-detectable but the product materials demonstrated atypical or nonlinear calibration behavior, four had detectable VAM in the 2–10 ppmw range, and eight had detectable VAM from 10 to 648 ppmw. Eleven use scenarios were developed based on seven categories of consumer products from the evaluation.

Intake fraction (iF) quantifies the relationship between emissions and exposure, defined as the ratio of the total inhalation increment of all exposed individuals in a target population to the emissions from specific pollution sources over a certain period. The overarching objective of this study is to unravel the underlying value and significance of the iF method in evaluating TRAP exposure risks, while also exploring its future development trajectories and potential avenues for application. We conducted a comprehensive review of iF to assess TRAP exposure. We employed a search strategy to identify and analyze literature on iF methods related to TRAP exposure across academic databases covering the period from 2002 to 2024. After deduplication, title and abstract screening, and full-text review, we ultimately included 25 studies on iF related to TRAP. We classified the measurement methods of iF into four types: simple estimation method, dispersion simulation method, numerical simulation method, and exposure monitoring method. We found orders of magnitude of differences in iF among studies. Population density, pollutant concentration, and breathing rate explain a significant portion of the variations. iF values of nitrogen oxides (NOx), carbon monoxide (CO), and fine particulate matter (PM2.5) are higher than those of diesel particulate matter (DPM), ultrafine particles (UFP), and benzene. Compared to power plants, TRAP has higher iF values, emphasizing the control priority of TRAP. Future research should expand to under-researched regions, strengthen investigations on UFP and secondary pollutants, and refine iF calculation methods using high-resolution and mobility data.","PeriodicalId":15684,"journal":{"name":"Journal of Exposure Science and Environmental Epidemiology","volume":"36 1","pages":"112-124"},"PeriodicalIF":4.7,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144319185","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}

While the associations between PFAS and certain adverse human health effects are well-documented, their impact on kidney function remains less known. The main aim of this study is to investigate the relationship between PFAS levels and kidney function (estimated glomerular filtration rate [eGFR]) utilizing a longitudinal design. The population-based Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS) study included 997 individuals at baseline (all aged 70 years, 50% females). Follow-up investigations were performed at 75 and 80 years of age. Seven major PFAS were determined in plasma using ultra-high performance liquid chromatography-mass spectrometry. Longitudinal and cross-sectional associations between PFAS and eGFR were analyzed using linear regression and mixed effects models following adjustment for sex, HDL and LDL-cholesterol, triglycerides, glucose, BMI, statin use and smoking. Longitudinal models demonstrated statistically significant positive associations between perfluoroundecanoic acid (PFUnDA), perfluorononanoic acid (PFNA), and perfluorodecanoic acid (PFDA)and eGFR (all P < 0.001). The associations between linear perfluorooctane sulfonic acid (PFOS) and perfluorohexanesulfonic acid (PFHxS) followed a similar trend. In contrast, an inverse relationship between perfluoroheptanoic acid (PFHpA) and perfluorooctanesulfonamide (PFOSA) with eGFR was observed. The findings were largely corroborated by cross-sectional analyses. This longitudinal study found that changes in certain PFAS concentrations were positively associated with the change in kidney function, though the direction of association varied across PFAS. These findings were further supported by cross-sectional analysis. The complexity of associations remains incompletely understood as some PFAS showed positive associations while others were inverse. Further longitudinal studies with repeated measures are needed to better elucidate the relationship between PFAS exposure and kidney function.","PeriodicalId":15684,"journal":{"name":"Journal of Exposure Science and Environmental Epidemiology","volume":"35 6","pages":"1041-1049"},"PeriodicalIF":4.7,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41370-025-00785-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144259831","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}

We linked AFO/CAFO data from seven states (Iowa, North Carolina, Pennsylvania, South Carolina, Texas, Virginia, and Wisconsin) to ZIP code-level census variables. We assessed exposure by calculating area-weighted number of AFO/CAFO within 15 km buffers and categorized ZIP codes into no, low, medium, and high exposure groups. Our analysis compared the spatial distributions of AFO/CAFO exposure and variables related to EJ and at-risk populations by exposure intensity. We found differences in the distributions of AFO/CAFO exposure and variables related to EJ and at-risk populations among states. In some states (e.g., North Carolina, Pennsylvania), AFOs/CAFOs were densely clustered in specific areas, while in others (e.g., Iowa, Wisconsin), they were more evenly distributed. We found disproportionate exposure to AFO/CAFO in disadvantaged communities such as communities with high percentages of racial/ethnic minority persons and low socioeconomic status in some states, whereas other states showed different patterns. Trends varied by state, with some showing increasing Non-Hispanic Black and Hispanic populations with higher exposure (e.g., North Carolina), while others showed opposite trends (e.g., Pennsylvania). Education, poverty, and income levels also varied, with some states (e.g., North Carolina, South Carolina) showing higher poverty rates, lower education level, and lower incomes in higher exposure groups and other states showing reverse trends (e.g., Wisconsin).","PeriodicalId":15684,"journal":{"name":"Journal of Exposure Science and Environmental Epidemiology","volume":"36 1","pages":"167-174"},"PeriodicalIF":4.7,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144248169","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}

This study used data from the fifth round of the National Family Health Survey (NFHS-5 collected 2019–2021), including health, socio-demographics, and food and dietary information (n = 712,666 individuals). The physicochemical characteristics of groundwater data were derived from the Central Groundwater Board (CGWB, 2019–2021). This groundwater data from raster maps was linked to NFHS-5 records using cluster shapefiles and merging them with individual records via cluster IDs. Bivariate and multivariable regressions were used to identify factors associated with hypertension at the individual level. Moran’s I statistics, Local Indicator of Spatial Association (LISA) cluster maps, and the Spatial Error Model (SEM) were used at district levels to investigate the spatial association. Machine learning models, including Artificial Neural Networks (ANN), Random Forest and Extreme Gradient Boosting (XGBoost), were used to predict hypertension risk zones. Physicochemical drinking water composition is a key factor in hypertension risk. Elevated groundwater pH (>8.5, Adjusted Odds Ratio (AOR): 2.12), electrical conductivity (>300 μS/cm, AOR: 1.06), sulphate (>200 mg/L,  AOR: 1.16), arsenic (>0.01 mg/L, AOR: 1.09), nitrate (>45 mg/L, AOR: 1.07), and magnesium (>30 mg/L, AOR: 1.03) are associated to higher odds of hypertension.

In this study, we investigated structural analogues and functional alternatives of bisphenol A (BPA) in 594 human milk samples collected from Canada (Montreal) and South Africa (Vhembe and Pretoria) using LC-Q-TOF-MS through suspect screening. Suspect screening was performed using data collected from the milk samples using a customized database library (204 compounds). A retrospective semi-quantitative approach was then applied to estimate the levels of TGSA, D-8 and D-90 in human milk. This work revealed the presence of eleven compounds, including four compounds commonly used in thermal labels, four ultraviolet filters, and three synthetic antioxidants or metabolites. Retrospective semi-quantification of D-8, D-90 and TGSA revealed levels of up to 1.24, 1.98, and 0.72 ng/mL in milk, respectively. Several structural analogues and functional alternatives of bisphenol A were identified in human milk through non-targeted screening. Two other phenolic compounds (Irganox 1010 and BHT-COOH) were identified in human milk for the first time.
