Multi-site study of communities with PFAS-contaminated drinking water: Methods, demographics, and PFAS serum concentrations
Science
11 Aug 2025 | Environ. Int.
In eight PFAS-affected U.S. communities, blood tests of 5,826 adults and 710 children from 2019 to 2023 found higher PFHxS and PFOA in adults and higher PFHxS only in children.

Serum Levels of Per- and Polyfluoroalkyl Substances in Adults Aged 18 and Older in Relation to the Length of Residency in United States
Science
11 Aug 2025 | J Immigr Minor Health
Immigrants to the U.S. tend to have lower levels of PFAS such as PFOA, PFOS, PFHxS, PFNA, and PFDeA upon arrival, but their levels increase over time, often matching those of U.S.-born people within 5 to 15 years, depending on race, ethnicity, and differences in past and ongoing environmental exposures.

Association of serum per-and polyfluoroalkyl substances exposure with leukocyte telomere length in Chinese middle-aged and older adults: Role of genetic susceptibility and healthy diet
Science
16 Jul 2025 | Environ Sci Technol
In nearly 1,500 middle-aged and older Chinese adults, higher blood levels of the PFDA and PFUDA were linked to noticeably shorter telomeres, with the greatest shrinkage in people who also carried aging-related genes and ate a low-quality diet, suggesting these chemicals may speed biological aging.

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.

Temporal changes in per and polyfluoroalkyl substances and their associations with type 2 diabetes
Science
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.

Per- and polyfluoroalkyl substances, genetic factors, and sleep health in reproductive-aged women: a cross-sectional study of the Shanghai Birth Cohort.
Science
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.

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.

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.

Distribution pattern, source apportionment and health risk assessment of per and polyfluoroalkyl substances in drinking water treatment plants in South Africa
Science
26 May 2025 | Environ Toxicol Chem
Testing of drinking‑water plants in five South African provinces revealed measurable PFAS, sometimes climbing to hundreds of nanograms per litre, with one Northern Cape facility exceeding safety thresholds.

Individual and mixtures of PFAS during pregnancy are associated with maternal cardiometabolic outcomes during pregnancy
Science
30 Apr 2025 | Environ Health
The majority of pregnant woman tested in central Arkansas had PFAS in her blood, and those with the highest levels showed shifts in cholesterol, triglycerides, resting pulse, and diastolic blood pressure— indicating potential harm to heart health during pregnancy.

PFAS concentrations in the blood of Danish surfers
Science
20 Jan 2025 | Int J Hyg Environ Health
PFAS concentrations in the blood of Danish surfers were measured, revealing no significant relationship between the amount of time spent surfing and higher PFAS levels, but male sex and eating meat from free-ranging animals were found to be potential risk factors for increased exposure.

[Press Release] Attorney General Bonta Co-leads Amicus Brief Defending Nationwide PFAS “Forever Chemicals” Drinking Water Standards
Policy
17 Jan 2025
California Attorney General Rob Bonta today co-led a coalition of 17 states in filing an amicus brief in the U.S. Court of Appeals for the D.C. Circuit defending a U.S. EPA rule establishing the first nationwide drinking water standards for certain toxic PFAS, also known as “forever chemicals,” under the Safe Drinking Water Act.

Sex specificity in associations between exposure to a mixture of per and poly-fluoroalkyl substances and anxiety among US adults
Science
7 Jan 2025 | J Expo Sci Environ Epidemiol
Exposure to mixtures of PFAS was linked to anxiety in U.S. adults, with males showing decreased anxiety and females showing increased anxiety, highlighting sex-specific effects.

Per-and polyfluoroalkyl substances in paired serum and breastmilk samples among pregnant farmworkers in Thailand
Science
16 Dec 2024 | Int. J. Hyg. Environ. Health.
PFOS and PFNA were the most commonly detected PFAS in breastmilk from Thai farmworkers, with lactational transfer efficiencies up to 14.7%, highlighting a significant route of postnatal exposure for infants.
