During the last decade, perfluorinated compounds (PFCs) have gained more attention due to their toxicity and global distribution. The aim of this study was to examine the distribution and bioaccumulation of perfluorinated compounds (PFCs) in aquatic wildlife effected from a sewage treatment plant. The concentrations of 12 PFCs were determined in water, sediment and fish samples. PFOS were predominantly detected in both ambient environment and fish. In fish, the concentration of PFCs in blood was the highest (i.e., 112.47 ng/mL wet-wt. PFOS) in comparison to other tissues. However, PFOA and PFHpS were highly detected in gonad as 3.87 and 4.58 ng/g wet-wt., respectively. The bioconcentration factor (BCF) of PFCs was greatest in the blood > liver${\cong}$gonad > kidney > gill, and lowest in the muscle tissue. The BCFs of PFUnDA (39,000), PFDA (2,700) and PFOS (1,100) were rated as high values based on wet weight concentration. BCFs increased with increasing the length of the perfluoralkyl chain.
