Analysis of legacy PFAS and potential precursors in curtain, sofa, and carpet fabric samples
2 Jul 2025 | Sci Total Environ
A European survey of 30 carpets, curtains, and sofa fabrics collected in 2023 found that household textiles can carry unexpectedly high levels of PFAS, often dominated by newer short-chain compounds, confirming these everyday items as a notable indoor source of PFAS exposure.
Exposure to per-and polyfluoroalkyl substances (PFAS) in healthcare: Environmental and clinical insights
1 Jul 2025 | Life
A review highlights that PFAS-containing plastics in many medical devices can leach into patients, especially vulnerable children, and urges safer materials, routine monitoring, and stronger regulation to curb this hidden exposure.
Temporal changes in per and polyfluoroalkyl substances and their associations with type 2 diabetes
1 Jul 2025 | Sci Rep
A 30-year Norwegian study found that blood levels of PFHpA, PFNA, PFHxS and PFHpS increased at a faster rate in people who later developed type 2 diabetes, indicating that exposure to these pollutants may play a role in the disease.
Development of chemical categories for per- and polyfluoroalkyl substances (PFAS) and the proof-of-concept approach to the identification of potential candidates for tiered toxicological testing and human health assessment
30 Jun 2025 | Comput Toxicol
US EPA researchers mapped about 15,500 PFAS, grouped them into 128 structural categories, and pointed out the biggest data gaps—so regulators can target testing the most concerning types instead of addressing each chemical one by one.
Per- and polyfluoroalkyl substances, genetic factors, and sleep health in reproductive-aged women: a cross-sectional study of the Shanghai Birth Cohort.
30 Jun 2025 | Environ Int
A Shanghai study of nearly 1,000 women found that higher blood levels of PFAS, particularly newer chlorinated alternatives and PFOS isomers, were linked to increased snoring, with genetics magnifying the risk.
Leachability of per-and polyfluoroalkyl substances in metal recycling streams
25 Jun 2025 | J. Hazard. Mater.
Automotive shredder residue, the mixed waste left after salvaging metal from cars, contains a suite of PFAS compounds that lab tests show readily leach into water, making it a persistent source of contamination in storm-water runoff and landfill leachate.
Investigation of Perfluorooctanesulfonic Acid (PFOS) and Perfluorooctanoic Acid (PFOA) Isomer Profiles in Naturally Contaminated Food Samples
25 Jun 2025 | J Agric Food Chem
Analysing PFOS- and PFOA-contaminated milk, deer meat, eggs and clams, FDA researchers found that calibrating with isomer-matched standards and quantifying branched and linear forms separately with a two-peak method decreased PFOS overestimation in branched-rich samples, while the distinctive isomer fingerprints traced some contamination to firefighting-foam runoff on dairy farms.
Enhanced immobilisation of per-and polyfluoroalkyl substances (PFAS) using a combination of sorbents and plants: A controlled rainfall simulation study
23 Jun 2025 | Sci. Total Environ.
Lab tests show that mixing PFAS-tainted soil with powdered activated carbon and planting hardy ryegrass on top prevented about 90% of the PFAS from being washed away by heavy rain, pointing to a simple, inexpensive way to keep PFAS out of nearby waterways.
Assessing contamination and risk profiles of per-and polyfluoroalkyl substances across various types of water in South Africa: trends over the past decade (2014–2024)
23 Jun 2025 | Emerging Contaminants
Across South Africa, surface waters and wastewater often contain PFOA and other PFAS at levels as high as 420 ng/L, creating serious ecological risks even though indirect human exposure through irrigated crops is currently minimal, underscoring the need for tougher regulation and better water treatment.
Association between exposure to bisphenols and per- and polyfluoroalkyl substances and behavioral problems among Chinese preschoolers
23 Jun 2025 | Ecotoxicol Environ Saf
A study of 823 Chinese preschoolers found that children with higher combined urine levels of certain BPA-replacement plastics and PFHxS were about twice as likely to show behaviour issues, including hyperactivity, anxiety and conduct problems, highlighting that these may be regrettable substitutes.
Chrome Plating Facility Siting Is Associated with Neighborhood Demographic and Socioeconomic Factors and Elevated Per- and Polyfluoroalkyl Substances in Blood in California
16 Jun 2025 | Environ Sci Technol
Residents living within 3 km of California chrome-plating shops showed markedly higher blood concentrations of specific plating-related PFAS—including PFOS, PFHxS, PFOA, PFHpS and PFPeS, underscoring how these mist-suppressant chemicals disproportionately burden nearby lower-income, largely Hispanic communities.
Heavier sediment pollution by per-and polyfluoroalkyl substances (PFASs) in tropical coasts compared to temperate regions: An overlooked hotspot
14 Jun 2025 | J. Environ. Sci.
Sediments along a tropical Chinese coastline contain markedly higher levels of both legacy and emerging PFAS, reaching about 13 ng/g dry weight and dominated by mid-chain compounds such as PFHxA and 9H-PFNA, a concentration exceeding those typically reported for temperate regions; researchers trace the pollution to land-based runoff, rocket-launch fallout, and other local sources.
Prenatal Per- and Polyfluoroalkyl Substance Exposures and Longitudinal Blood Pressure Measurements in Children Aged 3 to 18 Years: Findings From a Racially and Ethnically Diverse US Birth Cohort
12 Jun 2025 | J Am Heart Assoc
Higher maternal blood levels of eight PFAS (Me-PFOSA-AcOH, PFDeA, PFHpS, PFHxS, PFNA, PFOA, PFOS and PFUnA) correlated with higher childhood blood-pressure readings, most noticeably during adolescence, in boys and in non-Hispanic Black youth, implying that prenatal exposure to these “forever chemicals” may increase long-term hypertension risk.
Scientists’ statement on the chemical definition of PFASs
10 Jun 2025 | Environ. Sci. Technol. Lett.
The authors raise concerns about ongoing efforts to redefine PFAS and potentially exclude certain PFASs included under the 2021 OECD definition of PFAS chemicals. As there is no evidence to indicate that the OECD definition is flawed or problematic or ambiguous, there is no need for a new chemical definition.
Particle and per-and polyfluoroalkyl substance (PFAS) concentrations from different types of fire extinguishers
9 Jun 2025 | J. Hazard. Mater
Lab tests show that common foam fire extinguishers release PFAS in concentrations hundreds of times higher than powder or halon models—while powder units emit the most particles—highlighting the urgent need for safer foams and better protective gear.
