Environmental Occurrence and Biotic Concentrations of Ultrashort-Chain Perfluoroalkyl Acids: Overlooked Global Organofluorine Contaminants
Science
13 Nov 2024 | Environ Sci Technol
Ultrashort-chain perfluoroalkyl acids (PFAAs), including TFA, are widely present in the environment and living organisms, with rising concentrations over the past three decades, often exceeding those of longer-chain PFAAs in various ecosystems.

Permeation of Per-and Polyfluoroalkyl Substances (PFAS)-Laden Leachate in Landfills as an Outcome of Puncture Failures of High-Density Polyethylene Geomembranes
Science
12 Nov 2024 | Environmental Pollution
Puncture failures in high-density polyethylene landfill liners increase the permeation of hazardous PFAS-laden leachate. Short-chain PFAS, due to their surfactant properties, significantly enhanced permeation rates, highlighting concerns over environmental contamination if proper landfill protections are not maintained.

A Prospective Analysis of Per- and Polyfluoroalkyl Substances from Early Pregnancy to Delivery in the Atlanta African American Maternal-Child Cohort.
Science
6 Nov 2024 | Environ Health Perspect
Some PFAS concentrations, such as PFHxS and PFOS, increased throughout pregnancy and varied significantly based on maternal and socioeconomic factors, with shorter-chain PFAS transferring more efficiently to newborns, demonstrating a need for tailored public health interventions to protect newborns.

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.
