Abstract: The levels of Polycyclic Aromatic Hydrocarbons in Produced Water and the receiving Ugborodo River at Escravos, Nigeria were assessed in this study using Gas Chromatography-Mass Spectrometer. The results showed total PAH levels ranged between 0.726 and 1.215 ppm across all sampling stations. The maximum PAH level in fish sample A was 0.00573 ppm and in fish sample S was 0.00042 ppm. The Total Polycyclic Aromatic Hydrocarbon (PAH) levels were above the WHO limit of 0.0002 mg/L. The PAH levels obtained in this study may pose serious environmental and health risks due to bioaccumulation of these PAH compounds. There was significant difference in the levels of PAHs between the stations as well as the fish types. Thus, adequate treatment of the surface water in the study areas is recommended as this could reduce the PAHs levels in aquatic lives.
