- •
5 neutral and 8 ionic PFASs were detected in the atmosphere of Tianjin at 0.26–128 pg/m3.
- •
WWTPs can be a direct source of both neutral and ionic PFASs in the atmosphere.
- •
Majority of FTOHs was released to the atmosphere before grid separation at WWTPs.
- •
The release of ionic PFASs and FOSAs increased over aeration tank at WWTPs.
- •
PFOA and PFNA showed high LRAT potential due to their low association to particles.
