• 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. 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.

• Per-and polyfluoroalkyl substances and disrupted sleep: mediating roles of proteins

  Science

  23 Sep 2024 | Environmental Advances

  Exposure to certain PFAS chemicals has been associated with shorter sleep duration and increased sleep disturbances in young adults, potentially due to disruptions in metabolic and immune system functions.

• Multimedia and Full-Life-Cycle Monitoring Discloses the Dynamic Accumulation Rules of PFAS and Underestimated Foliar Uptake in Wheat near a Fluorochemical Industrial Park

  Science

  18 Sep 2024 | Environ. Sci. Technol.

  PFAS contamination near a major industrial park in China, particularly from airborne deposition, has led to significant accumulation in soil and wheat, with spray irrigation increasing PFAS absorption in wheat compared to flood irrigation. Local residents have high exposure risks through wheat consumption and air inhalation.

• It’s raining PFAS in South Florida: Occurrence of per-and polyfluoroalkyl substances (PFAS) in wet atmospheric deposition from Miami-Dade, South Florida

  Science

  9 Sep 2024 | Atmos. Pollut. Res.

  Rainwater in Florida contained significant levels of PFAS chemicals, including PFBA, PFNA, PFOS, and PFOA, particularly during the dry season, and analysis suggested both local and distant sources of contamination.
