Sammanfattning
Contamination of the water and sediment with per- and polyfluoroalkyl substances (PFAS) was studied for the lake impacted by the release of PFAS-containing aqueous film forming foam (AFFF). PFAS concentrations were analyzed in lake water and sediment core samples. sigma PFAS concentrations were in the range of 95-100 ng L(-1)in the lake water and 3.0-61 mu g kg(-1)dry weight (dw) in sediment core samples, both dominated by perfluorohexane sulfonate, perfluorooctane sulfonate; 6:2 fluortelomer sulfonate was inconsistently present in water and sediment core samples. The sediment-water partitioning coefficients (logK(d)) were estimated and ranged 0.6-2.3 L kg(-1)for individual perfluoroalkyl carboxylates (PFCAs) and 0.9-5.6 L kg(-1)for individual perfluoroalkane sulfonates (PFSAs). The influence of the sediment inorganic content and organic matter on PFAS distribution was investigated. In studied sediments, the mineral content (corresponding to
