Occurrence and Fate of Fluoroalkyl Sulfonamide-Based Copolymers in Earthworms–Bioavailability, Transformation, and Potential Impact of Sludge Application

To date, considerable knowledge and data gaps regarding the occurrence, environmental levels, and fate of polymeric perfluoroalkyl and polyfluoroalkyl substances (PFAS) exist. In the present study availability, accumulation, and transformation of C4- and C8-fluoroalkylsulfonamide (FASA)-based copolymers were assessed in laboratory-grown earthworms (
