Abstract

According to the study of polycyclic aromatic hydrocarbons in adipose and liver tissue of Rutilus frisii kutum existing in Nowshahr oil jetty (Caspian sea), 30 of them have been hunted through fishing net as samples and 3 stations have been considered for analysis at the beginning, in the middle and at the end of this waterfront. Sampling has been done on June 2010. Before any operation to prepare the samples, they were made biometric and the sex of each sample was determined. In order to analyze the dried samples, Soxhlet method, spanify method and extraction via organic matter is used, and to extract the organic material of water we used liquid-liquid method. In this work we determined the concentration of Anthracene, Payrn and Benzoe-alfapayrn, that are the three factors having genotoxic and carcinogenic potential. In this research, we achieved the average density of PAHs in liver tissue of (Bap=2.04, Ant=5.72, Pyr=7.71) mg/g, that is under the defined standard level by WHO. The average value of anthracene, pyrene and Benzo[a]pyrene compounds have been determined respectively 0.38 mg/L , 0.22 mg/L and 0.14 mg/L in different stations(initial, central, terminal).
