Occurrence and Fate of Per-and Polyfluoroalkyl Substances (PFAS) in Atmosphere: Size-Dependent Gas-Particle Partitioning, Precipitation Scavenging, and Amplification
Science
16 May 2024 | Environ. Sci. Technol.
Researchers in Shijiazhuang, China examined the distribution of PFAS in the atmosphere, finding that FCAs were the most prevalent, with their concentrations linked to the organic matter fraction across various particle sizes. Temperature influenced gas-particle partitioning and precipitation played a key role in removing PFAS from the atmosphere, despite temporary increases during rainfall events.

Association of diet with per- and polyfluoroalkyl substances in plasma and human milk in the New Hampshire Birth Cohort Study
Science
11 May 2024 | Sci Total Environ
Certain dietary factors during pregnancy, such as increased consumption of fish/seafood, eggs, coffee, or white rice, were found to be associated with higher concentrations of PFAS in both maternal plasma and human milk, indicating the importance of understanding food-related sources of PFAS exposure for pregnant individuals and their offspring. Fruit, whole grain, and fiber consumption was associated with lower levels of PFAS in maternal plasma.
