The Exposure Status of Environmental Chemicals in South Korea: The Korean National Environmental Health Survey 2018-2020
Science
19 Nov 2024 | Toxics
Among Korean adolescents, PFAS such as PFOA, PFOS, PFNA, and PFDeA were correlated with higher cholesterol levels, including LDL-C and total cholesterol. Adolescents highly exposed to both PFAS and heavy metals like mercury also had significantly higher lipid profiles.

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.

Exposure to per- and polyfluoroalkyl substances (PFAS) in North Carolina homes: results from the indoor PFAS assessment (IPA) campaign
Science
11 Nov 2024 | Environ Sci Process Impacts
Inhalation was the primary non-dietary indoor PFAS exposure for adults, while children are more exposed via ingestion of dust and hand-to-mouth behavior, with neutral PFAS being the dominant contributor.

Exposure to and Transplacental Transfer of Per- and Polyfluoroalkyl Substances in a Twin Pregnancy Cohort in Korea
Science
6 Nov 2024 | Environ Sci Technol
In twin pregnancies, higher levels of certain PFAS chemicals, like L-PFOS and PFOA, were found in the mothers' blood compared to their babies' cord blood. Differences in blood flow through the placenta were linked to varying PFAS levels between the twins, suggesting that the way these chemicals transfer from mother to baby can be affected by placental structure, potentially impacting health.

Relationship between per-fluoroalkyl and polyfluoroalkyl substance exposure and insulin resistance in nondiabetic adults: Evidence from NHANES 2003-2018
Science
5 Nov 2024 | Ecotoxicol Environ Saf
Higher exposure to PFAS chemicals, such as PFOS, PFOA, and MeFOSAA, is strongly associated with increased insulin resistance in adults, especially when measured by the TyG index, with the association stronger in younger individuals and those with higher BMI, emphasizing the health risks of PFAS exposure.

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.

Skin Permeability of Perfluorocarboxylic Acids Using Flow-Through Diffusion on Porcine Skin
Science
7 Oct 2024 | Toxics
Using porcine skin, PFBA showed higher skin permeability compared to other PFAS, and although overall absorption was low, these chemicals can accumulate in the skin, potentially acting as a long-term reservoir. Using porcine skin, PFBA showed higher skin permeability compared to other PFAS, and although overall absorption was low, these chemicals can accumulate in the skin, potentially acting as a long-term reservoir.

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.
