Hair analysis as a non-invasive method for assessing the exposure of wildlife to per- and poly-fluoroalkyl substances (PFAS)
Science
13 May 2025 | Environ Pollut
By analyzing blood samples from 700 adults in southern and eastern California, scientists found that even low but detectable PFAS in local tap water significantly raised people’s levels of the legacy chemicals PFOA and PFHxS, while seafood and eggs contributed smaller amounts.

Diet quality in relation to serum perfluoroalkyl substance concentrations in Canadian preadolescents
Science
6 May 2025 | Environ Res
In Canadian preadolescents, higher dietary intake of fat, fiber, and iron was associated with increased blood concentrations of several PFAS—especially PFOS, PFDA, and PFHxS—suggesting that most diets may contribute to PFAS exposure through contaminated food systems.

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.

Serum concentrations of per-and polyfluoroalkyl substances (PFAS) among men from the Danish fire services and Armed Forces
Science
25 Mar 2025 | Int. J. Hyg. Environ.
Civilian airport firefighters in Denmark showed slightly elevated blood levels of PFAS chemicals such as PFHxS, PFHpS, and PFOS—commonly found in firefighting foams—pointing to the need for stronger regulations and safer, non-toxic alternatives.

Exposure to per-and poly-fluoroalkyl substances and respiratory and skin effects in children and adolescents: A systematic review and meta-analysis
Science
19 Mar 2025 | J Hazard Mater
PFHxS was associated with an increased risk of atopic dermatitis, like eczema, in children, especially when exposure occurred during the prenatal period, suggesting that even early-life exposure to certain PFAS can impact immune and skin health.
-
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.

Associations of early life per- and polyfluoroalkyl substances (PFAS) exposure with body mass index and risk of overweight or obesity at age 2-18 years: Mixture analysis in the prospective Boston Birth Cohort
Science
15 Dec 2024 | Environ Int
Early-life exposure to PFAS is associated with an increased risk of childhood obesity, with effects influenced by maternal pre-pregnancy obesity, child age, and PFAS mixture, highlighting the need for further investigation into long-term health impacts and preventive strategies.

Examining Disparities in PFAS Plasma Concentrations: Impact of Drinking Water Contamination, Food Access, Proximity to Industrial Facilities and Superfund Sites
Science
14 Nov 2024 | Environ Res.
PFAS plasma levels were higher in individuals living near Superfund sites or PFAS-polluting facilities and in areas with low food access, with drinking water contamination contributing significantly to elevated plasma PFOS, PFOA, and PFHxS levels, highlighting disparities in PFAS exposure driven by industrial and socioeconomic factors.

Leachability of per- and poly-fluoroalkyl substances from contaminated concrete
Science
5 Nov 2024 | Environ Sci Process Impacts
PFAS chemicals, like PFOS and PFHxA, can leach significantly from concrete contaminated from use of aqueous film-forming foams at airports, defense, and port facilities, with leaching behavior influenced by factors like particle size, pH, and individual PFAS properties.

Determination of per- and polyfluoroalkyl substances (PFAS) in six different fish species from Swiss lakes
Science
1 Oct 2024 | Anal Bioanal Chem
Significant PFAS contamination was found in freshwater fish from Swiss lakes, particularly in European Perch, with PFOS and PFHxS levels often exceeding EU safety limits, highlighting the need for ongoing monitoring and regulation to protect aquatic ecosystems and human health through decreased fish consumption.

Prenatal exposure to PFAS and the association with neurobehavioral and social development during childhood
Science
25 Sep 2024 | Int J Hyg Environ Health
Prenatal exposure to PFAS shows mixed effects on children's neurobehavioral and social development markers like behavioral issues and anxiety, but strong associations were not found in this population with low PFAS exposure and depended on the children’s sex, type of PFAS, and developmental outcome.
