Occurrence, partitioning and transport of perfluoroalkyl acids in gas and particles from the southeast coastal and mountainous areas of China
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.
Infant formula and baby food as a source of perfluoroalkyl substances for infants
2 Dec 2022 | Environ Pollut

26 Nov 2022 | Int J Hyg Environ Health
The mixture risk assessments indicate that PFAS exposure is too high and may result in a human health risk.
[Letter] Global plastic treaty should address chemicals
24 Nov 2022 | Science
