Temporal trends and sediment–water partitioning of per- and polyfluoroalkyl substances (PFAS)in lake sediment
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...

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 Luleå, northern Sweden. In the aqueous phase, maximum ΣPFAS concentration was 1.700 ± 90 ng L −1 . Dominant PFAS groups were perfluoroalkane sulfonates (PFSAs)with 70% of the ΣPFAS, followed by perfluoroalkyl carboxylates (PFCAs, 29%), whereas the contribution of 6:2 fluorotelomer carboxylate (FTSAs)was low (<1%). In the sediment core samples, ΣPFAS concentrations ranged between <1 μg kg −1 dry weight (dw)and 76 μg kg −1 dw, where perfluorooctane sulfonate (PFOS)and perfluorohexane sulfonate (PFHxS)had an average contribution of ∼71% and ∼23% of the ΣPFAS.
