| Polycyclic Aromatic Hydrocarbons (PAHs) are stable organic compounds that their carcinogenic properties have been proved. This components enter to the organisms body throught food chain and affect the consumers adversely. This study was conducted in order to consider the effect of water soluble fraction of crude oil on the accumulation of PAHs in muscle tissue of Pseudorhombus elevatus of The Persian Gulf. It was performed in spring 2005 in the ecology research center of The Persian Gulf. Two solutions with 0ppm and 12ppm dosages of crude oil were prepared with Anderson method and seawater. Then 24 fish from this species that were caught randomly from 6 stations of The Persian Gulf were exposed to 0ppm and 12ppm dosages of crude oil for 8 days in long-term bioassay examination. After 8 days exposed fish were freezed and packed seprately and sent to the laboratory for determination of PAHs accumulated in their muscle. PAHs measurment was done with GC-FID model varian 3400. In this research, the amount of each compound of PAHs was detected. Then total PAHs in each dosage was calculated seprately. The result of data analysis shows that the mean accumulation amounts of PAHs ( STD) in tissues of testifier Pseudorhombus elevatus was 929.66 2.51 ppb. Also the mean accumulation amounts of PAHs ( STD) in tissues of Pseudorhombus elevatus which were exposed to 12 ppm dosage of crude oil was 3843 13.52 ppb. According to T-test test we concluded that there is a significant difference (p<0.05) between two mentioned dosages of crude oil from their accumulation point of view in muscle tissues of this species. In other words exposing fish to 12ppm of crude oil can increase the accumulation of PAHs in comparition with testifier fish. On the other hand, the high amount of PAHs in the testifier fishes is due to pollution of The Persian gulf. |
