Abstract
The use of per- and polyfluoroalkyl substances (PFAS) containing aqueous film forming foams (AFFF) at fire training facilities can have an adverse impact on the surrounding environment. The aim of the present study was to study the distribution and temporal trend of 26 PFAS in water and sediment cores for a lake and a pond affected by AFFF release from a fire training facility in Lulea, northern Sweden. In the aqueous phase, maximum Sigma PFAS concentration was 1.700 +/- 90 ng L-1. Dominant PFAS groups were perfluoroalkane sulfonates (PFSAs) with 70% of the Sigma PFAS, followed by perfluoroalkyl carboxylates (PFCAs, 29%), whereas the contribution of 6:2 fluorotelomer carboxylate (FTSAs) was low (
