Characterizing per-and polyfluoroalkyl substances (PFAS) exposure in petrochemical workers: Insights from paired blood and urine samples
9 Mar 2026 | Molecules
PFAS exposure in petrochemical workers is elevated relative to the general population but lower than highly exposed industries, with PFOA dominating blood burdens, PFPeA dominating urine, long-chain PFAS accumulating in blood while short-chain PFAS are preferentially excreted, and cumulative exposure primarily driven by years of occupational service.
Female reproductive toxicity of chronic exposure to perfluorohexane sulfonate (PFHxS) under the confounding factor of dietary protein deficiency
9 Mar 2026 | Reprod Toxicol
Chronic exposure to PFHxS in rats especially combined with a low-protein diet was associated with ovarian damage, hormonal disruption, inflammation, and fibrosis.
Insights on the adsorption of per-and polyfluoroalkyl substances onto laboratory syringe membrane filters: Experimental, materials, and mechanism evaluations
7 Mar 2026 | ACS ES&T Water
Filtration through common laboratory syringe membrane filters may cause PFAS to adsorb to the filter material, potentially leading to underestimation of concentrations, with adsorption influenced by filter composition, surface area, water chemistry, and PFAS chain length.
Integrating target, nontarget analysis with machine learning to illuminate PFAS characteristics and health risks in Chinese cosmetics
7 Mar 2026 | Environ Pollut
Analysis of commonly used Chinese cosmetics including face creams, lotions, sunscreen, mascara, eyeshadow, foundation, antiperspirant, shampoo, and facial wash detected multiple PFAS, including PFOA, PFNA, PFBS, PFHxS, and fluorotelomer sulfonates, with risk estimates suggesting dermal exposure from some items may exceed Texas safety thresholds.
Spatial analysis of residential location at birth, PFAS in public water, and childhood cancers in Southern California (2000-2019).
5 Mar 2026 | J Expo Sci Environ Epidemiol
Prenatal exposure to PFOA and PFOS in drinking water may be linked to increased risk of certain childhood cancers, particularly neuroblastoma and retinoblastoma, and may contribute to elevated cancer incidence in areas with contaminated water systems.
Asian/Pacific Islander Community Exposures (ACE) Project
3 Mar 2026
Factors affecting levels of these chemicals could include dietary preferences, such as regular consumption of fish and rice, and the use of traditional remedies, such as some herbal medicines.
The differences in levels of poly- and perfluoroalkyl substances (PFASs) in the hair of wild terrestrial mammals with various feeding behaviour
3 Mar 2026 | Sci Rep
PFAS were detected in the hair of wild mammals including wolves, red foxes, badgers, wild boar, and deer, with higher levels generally observed in predatory species such as wolves and foxes, suggesting environmental exposure and possible biomagnification through food webs.
PFAS reduction during biosolids drying correlates to initial moisture content and is accompanied by detection of PFAS in dryer condensate
2 Mar 2026 | Environ. Sci.: Water Res. Technol.
Drying of wastewater biosolids may reduce detectable PFAS concentrations, but the study suggests this reduction is partly due to PFAS transferring into vapor condensate or transforming into other forms, meaning the process could shift contamination rather than eliminate it and may require additional treatment controls to prevent environmental release.
Association between prenatal exposure to per-and polyfluoroalkyl substances and pubertal development in boys and girls in the Spanish INMA cohort
26 Feb 2026 | Environ Res
Prenatal exposure to PFHxS, PFOS, PFOA, and PFNA may be associated with changes in the timing of puberty, with PFHxS linked to earlier adrenal maturation in girls and PFOS showing mixed patterns across sexes, supporting concerns that PFAS may influence endocrine pathways during development.
Per-and polyfluoroalkyl substances (PFAS) and menstrual cycle characteristics in midlife women: The Study of Women’s Health Across the Nation
26 Feb 2026 | Reprod Toxicol
Higher serum concentrations of several PFAS, including PFOS, PFOA, PFNA, and PFHxS, were associated with greater variability in menstrual cycle length and shorter or lighter menstrual bleeding among midlife women.
Mortality of workers exposed to tetrafluoroethylene (TFE) and perfluorooctanoic acid (PFOA) in a plant producing fluoropolymers in Italy, 1960-2024
26 Feb 2026 | Occup Environ Med
A cohort study of Italian fluoropolymer workers found elevated mortality from non-Hodgkin’s lymphoma that was positively associated with TFE exposure and employment duration.
Emerging PFAS contaminants PFNA and PFSA amplify epigenetic aging: Sex-and age-stratified risks in an aging population
25 Feb 2026 | Frontiers in Aging
Higher serum levels of perfluorononanoic acid perfluoroalkane sulfonic acid were associated with accelerated DNA methylation–based aging markers in older U.S. adults, particularly mortality-related measures in males and middle-aged individuals.
Diet and everyday product use and serum per-and polyfluoroalkyl substances levels in the Korean population: Findings from the Korean national environmental health survey
23 Feb 2026 | Environ. Res.
Higher serum PFAS levels were most strongly associated with seafood intake, especially fish and shellfish, and with use of food contact materials such as disposable paper cups, plastic pouches, and coated cookware, while a distinct pattern suggested PFHxS may be more closely linked to fast food consumption and personal care or household products.
Quantitative Associations of Per- and Polyfluoroalkyl Substances in Segmented Hair with Serum and Dust: Potential of Hair as a Retrospective Biomarker
23 Feb 2026 | Environ Sci Technol
In a two-year panel of female e-waste workers, concentrations of long-chain perfluorosulfonic acids in segmented hair were positively associated with corresponding average serum levels over matched prior months, suggesting hair may retrospectively reflect internal exposure, while short-chain PFAS showed weaker or inconsistent relationships.
Characteristics of 'early adopters' of water treatment capacity needed to remove PFAS and other emerging contaminants in the United States
23 Feb 2026 | Environ Sci Process Impacts
Using a national time-to-event analysis of more than 36,000 U.S. community water systems, researchers found that larger systems adopted PFAS-relevant treatment technologies such as reverse osmosis and activated carbon substantially faster than smaller systems, and that systems serving higher proportions of Black residents were less likely to adopt these technologies.
