Study of water soluble of crude oil pollution effects on PAHs accumulation in four commercial fish species of the Persian Gulf
One of the compounds of crude oil is Polycyclic Aromatic Hydrocarbons (PAHs). This study was conducted in the toxicology laboratory of Persian Gulf and Oman Sea Research Center, Bandar Abbas in Spring 2005. Four commercial fishes were exposed to Oppm and 12ppm dosages of crude oil in long-term bioassay examination. After 8 days, exposed fish were freezed and packed seprately and then sent them to IBB (Institute of Biochemistry and Biophysics) of Tehran University for determination of PAHs accumulated in their muscle. PAHs measurment was done with GC-FID. In this research, the amount of each compound of PAHs and total PAHs in each dosage was calculated seprately for each species. The result of data analysis shows that the mean accumulation amounts of PAHs (SD± Y. ) in tissues of control Pseudorhombus elevates, Euryglossa orientalis, Siganus javus and S. sutor exposed to Oppm dosage of crude oil were 929.66±251ppb, 1009±-11.7ppb, 1131±-35.0ppb and 487.6±4.0ppb and mean accumulation amounts of PAHs (SDA:i ) in those exposed to 12ppm dosage of crude oil were 3843±13.52ppb, 4272±18.77ppb, 2911±3 5. 5ppb and 2309.6±11.3ppb respectively. According to t-test, we concluded that in all four species the accumulation of crude oil in their muscle tissues between two mentioned dosages were significantit difference (P<0.05). On the other hand, the high amount of PAHs in the control fishes probebly is due to pollution of Persian Gulf.
