Paints: A Source of Volatile PFAS in Air - Potential Implications for Inhalation Exposure
11 Nov 2022 | Environ Sci Technol
Common paints were found to contain 6:2 FTOH and 6:2 diPAP that accounted for up to 17% of total fluorine, with 40% of FTOH mass lost upon drying. Exposure estimates suggest that PFAS exposure while painting could exceed recommended reference doses for children and adults.
