Suspect screening of per- and polyfluoroalkyl substances in new firefighter turnout gear textiles
20 Mar 2025 | NIST
Firefighter turnout gear was found to contain a wide variety of PFAS chemicals—including newly detected compounds like perfluorobutane sulfonamido ethanol and 6:2 fluorotelomer sulfate—highlighting that even new gear may expose firefighters to harmful substances, reinforcing the urgent need for broader chemical screening and safer materials.
Exposure to per-and poly-fluoroalkyl substances and respiratory and skin effects in children and adolescents: A systematic review and meta-analysis
19 Mar 2025 | J Hazard Mater
PFHxS was associated with an increased risk of atopic dermatitis, like eczema, in children, especially when exposure occurred during the prenatal period, suggesting that even early-life exposure to certain PFAS can impact immune and skin health.
Unraveling the Exposure Spectrum of PFAS in Fluorochemical Occupational Workers: Structural Diversity, Temporal Trends, and Risk Prioritization
18 Mar 2025 | Environ Sci Technol
Researchers analyzed the blood of fluorochemical plant workers in China and found 64 types of PFAS chemicals—including 15 previously unknown ones—with some linked to high health risks due to their persistence and ability to accumulate in the body, highlighting the need for stricter monitoring and regulation of these toxic substances.
Leaching profile of per-and polyfluoroalkyl substances from selected e-waste components and potential exposure pathways from discarded components
17 Mar 2025 | J Hazard Mater
Discarded electronics like cables, keyboards, monitors, and circuit boards can release harmful PFAS—especially PFBA, PFHxA, PFOA, and PFOS—into the environment through leaching, highlighting e-waste as a significant but underrecognized source of long-term contamination and exposure risks.
High levels of flame retardants in vehicle dust indicate ongoing use of brominated and organophosphate flame retardants in vehicle interiors
15 Mar 2025 | Environ Monit Assess
PFAS were found at low but widespread levels in car interior dust—especially on dashboards—indicating their continued use in materials like stain-resistant coatings and plastics despite increasing regulations.
Per- and poly-fluoroalkyl substances (PFAS) in circulation in a Canadian population: their association with serum-liver enzyme biomarkers and piloting a novel method to reduce serum-PFAS
15 Mar 2025 | Environmental Health
A fiber-rich oat β-glucan supplement was found to possiblt help lower levels of certain harmful PFAS chemicals in the blood, suggesting a potential dietary approach to reduce long-term exposure.
Ten years of PFOS and PFOA human biomonitoring in Italy: Exposure levels and determinants of exposure
14 Mar 2025 | Chemosphere
PFAS exposure in the Italian population has declined over ten years for PFOA but not for PFOS, with higher levels observed in men, individuals in urbanized areas, and those with higher education or occupational skill levels, while proximity to PFAS-emitting industries remains the strongest predictor of elevated exposure.
Estimating historical PFAS exposures in Ronneby, Sweden using biobanked dried blood spots from newborns
13 Mar 2025 | Environ Res
Researchers used newborn blood samples stored in Sweden's national biobank to show that residents of Ronneby were exposed to toxic PFAS chemicals from contaminated drinking water as early as 1985, with levels rising steadily until 2013 due to fire-fighting foam used at a nearby military airport.
Perfluoroalkyl and polyfluoroalkyl substance detection in brewed capsule coffee
13 Mar 2025 | Foods
Machine-brewed capsule coffee was found to contain more PFAS chemicals like PFOA and 8:2 FTS than manually brewed coffee.
Degree of food processing and serum poly- and perfluoroalkyl substance concentrations in the US National Health and Nutrition Examination Survey, 2003-2018.
10 Mar 2025 | Int J Hyg Environ Health
PFOA levels were associated with higher intake of processed and lower intake of unprocessed/minimally processed foods, suggesting that food contact materials, rather than the foods themselves, might be an important source of exposure to PFOA.
Prenatal per- and polyfluoroalkyl substances and blood pressure trajectories in the New Hampshire Birth Cohort Study
8 Mar 2025 | Int J Hyg Environ Health
Higher prenatal exposure to PFAS is associated with increased blood pressure during pregnancy, even among women without hypertension, suggesting that these chemicals may contribute to adverse maternal and child health outcomes.
