• Impact of local food consumption on exposure to perfluorooctanoic acid and perfluorooctane sulfonate in a contaminated community in North-Eastern Italy

  Science

  30 Nov 2024 | Epidemiol Prev

  Consuming locally-grown foods in PFAS-contaminated areas can significantly increase exposure to PFOA and PFOS, leading to prolonged elevated blood levels, with affected individuals taking about three more years to reduce their concentrations to levels below a clinically significant threshold level.

• Exploring Perfluoroalkyl Substances Contamination in Human Breast Milk: First Ghanaian Study

  Science

  29 Nov 2024 | Chemosphere

  Human breast milk in Ghana contains detectable levels of PFAS, including PFHxA, PFHpA, PFOA, and PFOS, highlighting potential exposure risks to infants through breastfeeding, especially for PFOS and PFOA.

• Associations between per-and polyfluoroalkyl substances and menstrual cycle regularity in reproductive-aged female: a cross-sectional study

  Science

  25 Nov 2024 | Emerging Contaminants

  Exposure to branched PFOS and PFNA was significantly associated with irregular and long menstrual cycles, with these effects being more pronounced among women with low physical activity, suggesting potential reproductive risks linked to PFAS exposure and the influence of lifestyle factors.

• 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.

• Study of Endocrine-Disrupting Chemicals in Infant Formulas and Baby Bottles: Data from the European LIFE-MILCH PROJECT

  Science

  18 Nov 2024 | Molecules

  Infant formulas and baby bottles were found to contain endocrine-disrupting chemicals, including PFAS such as PFOA, PFBS, PFDA, PFHxA, and PFHpA, along with phthalates, bisphenols, metals, and more, highlighting the need for stricter monitoring and public health interventions to protect infants.

• Association between Exposure to Per- and Polyfluoroalkyl Substances and Missed Miscarriage: A Hospital-Based Case-Control Study in Shanghai, China

  Science

  16 Nov 2024 | Environ Toxicol Pharmacol

  Plasma concentrations of 13 PFAS, including PFOA, L-PFOS, and 6:2 Cl-PFESA were significantly associated with increased risk of miscarriage in women, with PFOA showing the strongest association, highlighting the reproductive risks linked to PFAS exposure.

• 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.

• Regulation of terrestrial input and ocean processes on the occurrence and transport of traditional and emerging per-and polyfluoroalkyl substances in the inner shelf of the East China Sea

  Science

  21 Oct 2024 | Water Research

  Coastal oceans show significant accumulation of PFAS in nearshore waters due to terrestrial inputs, industrial sources, and hydrological conditions, with certain PFAS compounds posing elevated ecological risks in regions like the East China Sea.

• Serum per- and polyfluoroalkyl substance (PFAS) levels and health-related biomarkers in a pilot study of skiers in New England

  Science

  8 Oct 2024 | Environ Res

  Ski coaches were found to have elevated levels of PFAS through ski wax exposure as well as higher cholesterol levels, suggesting a need for interventions to reduce PFAS in ski waxes and limit environmental release.

• 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.
