The main effluent of oil and gas production is the discharge of produced water (PW). Despite the potential environmental impact, the structure of oil and gas platforms can act as artificial reefs. Two species of fish, Caranx crysos and Tylosurus acus , were captured under two discharging platforms at Campos Basin, P19 and P40. A nondischarging platform, P25, was taken as reference. The highest median concentration of PAH in muscle tissue was observed for C. Crysos at P40 (219.38 ng g −1 ) followed by P19 (68.26 ng g −1 ). For T. acus , the highest median concentrations were 40.07 and 42.21 ng g −1 from P19 and P40 respectively. P25 presented the smallest recorded concentrations. The results of PAH in the muscle tissue of C. crysos enabled to distinguish the platforms with PW discharge from the platform without discharge. Trace elements concentrations reflected the background levels and were not influenced by the PW release.
