On the fluoropolymers and ultra-short PFAS topic: Aqueous Leaching of Ultrashort-Chain PFAS from (Fluoro)polymers: Targeted and Nontargeted Analysis
Science
19 Feb 2024 | ES&T Letters
All tested fluoropolymers, as well as non-fluorinated alternatives like PEEK, were found to leach C2-C4 PFCAs, likely related to their production such as processing aids, residuals, and inhibitors. This indicates that fluoropolymers and other plastics can emit short chain PFAS into the environment.
