Occurrence, partitioning and transport of perfluoroalkyl acids in gas and particles from the southeast coastal and mountainous areas of China
Science
5 Dec 2022 | Environ Sci Pollut Res Int.
The longer the fluorinated carbon chain length of the PFAA, the more the PFAA tended to exist in the particulate phase, and PFAS in China can be widely spread through the atmosphere due to winter monsoon winds.
