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.
