Levels of serum per- and polyfluoroalkyl substances and association with dyslipidemia in the Korean population
Science
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.

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)
Science
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.

The Shifting Nature of the PFAS Regulatory Landscape
News
19 Jun 2025 | The National Law Review
The slow pace of study has made enforcement of rules regarding PFAS inconsistent (and the subject of legal challenges) and has caused a substantial amount of confusion and uncertainty among industry, municipalities, and consumers.

Chrome Plating Facility Siting Is Associated with Neighborhood Demographic and Socioeconomic Factors and Elevated Per- and Polyfluoroalkyl Substances in Blood in California
Science
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
Science
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
Science
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.

Burden of per- and polyfluoroalkyl substances (PFAS) in human breast milk: Implications for maternal and infant health
Science
7 Jun 2025 | Environ Int
Analyzing pooled breast-milk samples from five UN regions, researchers estimate that up to 24 % of mothers and 17 % of babies already exceed plasma levels of PFHxS and PFNA linked to endocrine, immune and developmental harm.

Decorative cosmetics and skin care products contribute significantly to short-chain perfluoroalkyl carboxylates exposure
Science
5 Jun 2025 | J Hazard Mater
Tests on 3-D human skin models show that decorative cosmetics and skin-care products permit short-chain PFAS, such as by PFBA, to pass through skin efficiently, pushing daily intakes up to about 0.8 ng per kilogram of body weight and making dermal contact responsible for roughly 40 % of total PFOA exposure among regular users, findings that strengthen the case for tighter limits on PFAS in personal-care items.

Per-and polyfluoroalkyl substances suppress macrophage alternative activation to disrupt hepatic lipid metabolism
Science
29 May 2025 | Chem. Res. Toxicol.
Experiments in cells and mice show that two common PFAS, PFOA and PFUnDA, damage liver immune cells that maintain fat processing, leading to enlarged livers and body‑wide lipid imbalances, evidence that PFAS pollution could silently impact metabolic health.

These 29 Bucks County water suppliers tested above EPA limits for forever chemicals in ’24
News
29 May 2025 | Phillyburbs
PFAS readings in dozens of Bucks County water systems fell between state and federal limits last year: They didn't test high enough on a regular basis to qualify for a violation under state environmental regulations, but they consistently tested above the EPA's limit.

Per-and polyfluoroalkyl substances (PFAS) in placental compartments: Histopathological and toxicological data integration in an Italian cohort
Science
27 May 2025
Placenta samples from Italian pregnancies almost always contained multiple PFAS chemicals, and higher levels were tied to blood‑flow problems and abnormal growths, suggesting these persistent pollutants may disrupt normal placental function and threaten pregnancy health.
