• 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.

• 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.

• 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.

• 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.

• 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.

• Assessment of Per-and Polyfluoroalkyl Substances (PFAS) in Traditional, Organic and Protein Flours

  Science

  3 Sep 2024 | Exposure and Health

  Flours, including traditional, organic, and protein varieties, contain detectable levels of specific PFAS like PFOA and PFDA, potentially contributing significantly to overall PFAS exposure, yet current regulations lack specific safety limits for these contaminants in flours.

• Asthma and Decreased Lung Function in Children Exposed to Perfluoroalkyl and Polyfluoroalkyl Substances (PFASs): An Updated Meta-Analysis Unveiling Research Gaps

  Science

  23 Aug 2024 | Environ. Res.

  Exposure to PFOA is associated with a higher risk of asthma in children, while PFOS does not show a clear link to decreased lung function. Further research with larger and more consistent studies is needed to better understand these relationships and their underlying mechanisms.

• The perfluorooctanoic acid accumulation and release from pipelines promoted growth of bacterial communities and opportunistic pathogens with different antibiotic resistance genes in drinking water

  Science

  22 Aug 2024 | J Hazard Mater

  PFOA promotes the growth of harmful bacteria and the spread of antibiotic resistance genes in drinking water by enhancing bacterial metabolism, increasing protective substances, and facilitating gene transfer, leading to serious health risks.
