Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are widely distributed in the environment. In this study the accumulation potential of PFOA and PFOS in two fish species with different feeding strategies, i.e. chub (Leuciscus cephalus) and river goby (Gobio gobio) inhabiting a river receiving treated waste waters from a municipal waste water treatment plant, were estimated. PFOS was detected in chub (7–250 μg kg−1 wet weight) and river goby (70–400 μg kg−1 wet weight) with bioaccumulation factors (BAFs) of 4600 (liver) and 11,000 (organs). PFOA concentrations in both fish were low and in chub mostly below detection limit.
