PFAS exposure, mental health, and environmental justice in the United States: Impacts on marginalized communities
9 Jul 2025 | Int. J. Environ. Res. Public Health
PFAS exposure was associated with increased anxiety, depression, cognitive decline, and chronic stress in marginalized communities, highlighting racial and socioeconomic disparities in contamination and mental health impacts across the U.S.
Smoldering treatment of PFAS: Investigation of mass balance and volumetric scale up for field implementatio
8 Jul 2025 | ACS Omega
Engineers have conducted a proof-of-concept study to show that a self-sustaining “smoldering” treatment, enhanced with calcium oxide, can scale from lab columns to 10 m³ soil piles and destroy >99.9 % of PFAS while trapping the released fluorine as benign calcium fluoride, pointing to an energy-efficient, potentially field-ready solution for cleaning contaminated fire-training sites.
Levels of serum per- and polyfluoroalkyl substances and association with dyslipidemia in the Korean population
7 Jul 2025 | Ecotoxicol Environ Saf
A large national study of nearly 3,000 Korean adults found widespread PFAS exposure and showed that higher serum concentrations of several compounds, especially PFOA, PFHxS, PFNA and PFDeA, were consistently associated with elevated low-density lipoprotein cholesterol and total cholesterol, implying potential cardiovascular risk and reinforcing the need for stricter regulation.
Association between prenatal exposure to per-and polyfluoroalkyl substances and blood pressure among preschool-aged children: The moderating effect of child-age and the mediating effect of inflammatory cytokine
5 Jul 2025 | Ecotoxicol Environ Saf
Tracking 215 mother-child pairs in China, researchers found that prenatal exposure to common PFAS chemicals was associated with higher diastolic blood pressure in preschoolers, and that inflammatory signals in cord blood partly explained the effect, pointing to a subtle early-life pathway by which PFAS may increase the likelihood of later heart-disease risk.
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.
What people in the United States are asking about per and polyfluoroalkyl substances in their drinking water based on online search behaviors
1 Jul 2025 | J. Environ. Health.
Analysis of U.S. Google searches show most people asking about PFAS in drinking water are seeking practical ways to reduce exposure, providing insight into what type of information should be the focus of public health messaging.
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.
