| Description | In 2018, the Department of Ecology conducted follow-up sampling of freshwater fish from three urban lakes to gain a fuller understanding of per- and polyfluoroalkyl substances (PFAS) in urban fish. Ecology collected a total of 328 fish from Lake Meridian, Lake Sammamish, and Lake Washington and composited individual fillets into 76 samples for analysis of PFAS. All of the study’s samples contained perfluorooctane sulfonate (PFOS). Species-specific concentrations of PFOS were similar across all sites in the three lakes. Largemouth bass contained the highest PFOS concentrations, followed by yellow perch, and then brown bullhead, with medians of 30.7, 19.8, and 2.1 ng/g ww, respectively. Long-chain perfluoroalkyl carboxylates were detected in all or almost all of the samples, at much lower concentrations (medians < 2 ng/g ww). Perfluorooctanoate (PFOA) and short-chain perfluoroalkyl acids were not detected in any of the samples for this study. |
