Analysis of in vitro profiling data of cosmetic ingredients within the Tox21 10K compound library for bioactivity and potential toxicity
16 Jun 2026 | BMC Pharmacol Toxicol
Banned ingredients, including PFAS and phthalates, were more active than non-banned ingredients in CYP inhibition, estrogen/androgen signaling, while some non-banned cosmetic ingredients showed similar toxicity-related bioactivity, suggesting current bans may not fully capture potentially hazardous ingredients.
Fate of per-and polyfluoroalkyl substances (PFAS) in a mega-city wastewater treatment network: The ‘Precursor Paradox’in transitioning to 100% water reclamation
16 Jun 2026 | Sci Total Environ
Four Los Angeles wastewater treatment plants found that PFAS precursors can transform during treatment into measurable PFAS, while reverse osmosis removes >99% from recycled water but concentrates PFAS up to 40-fold in brine, making brine disposal a key challenge for water reclamation.
Early life uptake and elimination of per-and polyfluoroalkyl substances in a seasonally invertivorous bird
14 Jun 2026 | Environ Sci Technol
Juvenile house sparrows near urban-industrial PFAS sources had the highest early-life PFAS burdens, likely from maternal transfer and invertebrate-heavy diets, with concentrations declining as they matured, highlighting early development as a vulnerable exposure window in terrestrial birds.
Per‐and polyfluoroalkyl substances (PFAS) exposure profiles and their predictors in a study of us volunteer firefighters
14 Jun 2026 | Am J Ind Med
Among 550 U.S. volunteer firefighters, higher PFAS levels were linked more to age, sex, income, education, geography, and health behaviors than to most firefighting factors, but the authors note that the findings may not apply to professional firefighters who have different call times, work schedules, and occupational exposure patterns.
Lactation interrupted: PFAS impact on capacity to breastfeed ignored
13 Jun 2026 | Curr. Environ. Health Rep.
PFAS exposure may reduce breastfeeding duration by disrupting mammary gland development and lactation function, yet these impacts are often overlooked in PFAS risk assessment, regulation, and clinical guidance.
Establishing evidence-based standards for PFAS destruction pathway claims
11 Jun 2026 | ES&T Engineering
Researchers propose an evidenced-based framework for PFAS destruction studies to avoid overclaiming by matching conclusions to the strength of the supporting data.
Socioeconomic disparities in PFAS exposure and susceptibility to diabetes in Chinese adults: A nationwide cross-sectional study
10 Jun 2026 | Environ. Health
Using serum PFAS measurements from 10,302 adults, researchers found that higher socioeconomic status was associated with significantly higher levels of several PFAS, while lower socioeconomic status was linked to significantly stronger PFAS-diabetes associations for PFUnDA, PFOS, and 6:2 CI-PFESA, highlighting socioeconomic disadvantage as a potential factor in PFAS-related health susceptibility.
Individual and joint association between per- and polyfluoroalkyl substances and skeletal muscle among 6-9 years old children in China
9 Jun 2026 | Int J Hyg Environ Health
In a snapshot study of 422 young children in Guangzhou, higher exposure to several longer-chain PFAS was associated with lower measures of skeletal muscle mass, with mixture analyses showing similar negative trends.
Hereditary PCOS and the environmental toxicant F-53B converge on lipid metabolic reprogramming to impair fetal brain development
8 Jun 2026 | Ecotoxicol. Environ. Saf.
Maternal polycystic ovary syndrome(PCOS) and exposure to F-53B together may harm fetal brain development by disrupting lipid metabolism and reducing important brain cells needed for normal nerve and glial cell formation. F-53B (chlorinated polyfluorinated ether sulfonates) for decades have been used as a PFOS alternative in Chinese electroplating industries and is now frequently detected in surface waters, biota, and human samples.
Legacy and emerging per-and polyfluoroalkyl substances (PFAS) in glacial meltwater from Mt. Everest
8 Jun 2026 | Environ. Sci. Technol.
PFAS were detected in Mt. Everest glacial meltwater, where short-chain compounds such as PFBA dominated, meltwater flow appeared to drive PFAS release, and nontarget analysis identified emerging hydrogen-substituted PFAS not previously reported in glacial meltwater.
Dynamic exposure to per- and polyfluoroalkyl substances and early alterations in cardiovascular hemodynamics: A 10-year longitudinal study in adolescents and young adults
5 Jun 2026 | Int J Hyg Environ Health
A long-term study of 310 adolescents and young Taiwanese adults indicates that PFAS exposure may contribute to early cardiovascular changes in young people by increasing vascular resistance and lowering cardiac output.
Impact of chronic single or combined exposure to bisphenol A and perfluorooctanoic acid on human osteoblast spheroid
4 Jun 2026 | Environ Pollut
A human 3D model results indicate that chronic exposure to BPA and PFOA can harm human bone-forming cells by disrupting spheroid structure, collagen organization, and mineralization, highlighting the importance of human models in evaluating exposure hazards.
Accumulation of PFAS in wine from a contaminated area: Perfluorobutanoic acid (PFBA) as a molecular marker of PFAS groundwater contamination and implications of wine ingestion for human health
3 Jun 2026 | Environ Pollut
PFAS-contaminated groundwater can transfer into wine, with PFBA serving as a key marker of contamination, making wine both a possible indicator of local PFAS pollution and a potential dietary exposure source in heavily impacted areas.
Concentrations of perfluoroalkyl substances in the dust of Japanese households and buildings; Implications for human exposure
1 Jun 2026 | Atmos. Pollut. Res.
PFOS, PFOA, and PFNA remain persistent in indoor dust despite phaseouts, with campus and public buildings containing more than 16x higher PFAS concentrations than household dust.
Serum PFAS mixtures and risk of ovarian hyperstimulation syndrome in women undergoing assisted reproduction
1 Jun 2026 | Environ Int
Higher levels of some PFAS were linked to a dangerous side effect of fertility treatment that can make the ovaries swell and cause fluid buildup or other serious health problems supporting the rationale for preconception PFAS biomonitoring and targeted exposure reduction in reproductive-age women.
