Abstract

Background and purpose: Polycyclic aromatic compounds (PAHs) due to its high toxicity are considered as priority organic compounds pollutants worldwide. Due to the presence of oil wells, petroleum hydrocarbon is one of sources of pollution in the CASPIAN SEA. These are the pollutants of soil and water which are very dangerous and lethal for the aquatic ecosystem. The purpose of this study is conducted to determine the 16PAHS (as oil pollution) in the SEDIMENTS and two commrecial FISH of the CASPIAN SEA.Materials and methods: In this study, 32 sediment samples were collected from 8 stations at eight transects at 10 meter depth during for seasons. In addition, 34 samples of Liza saliens (17 samples) and Rutilus frisii kutum (17 samples) were taken in the southern of CASPIAN SEA. The samples were extracted using Soxhlet excrator with orgnic solvents and then analysis by GC-FID (Shimadzu-14 A) instruments.Results: Concentration of 16PAHS in sediment was observed lower than critical level (NOAA standard) in the most stations. Applying different PAHs ratios, it was found that PAHs originated predominantly from the pyrogenic source either from the combustion of grass, wood and coal (majority of the samples) or from petroleum combustion (harbour area). The mean concentration of PAHs in Liza. s and R. frisii kutum were observed 2460±60 and 2710±56 mg/kg dw and for sediment was 990±33 mg/kg dw. In general, concentrations of PAHs in edible tissue of two species were higher than their corresponding sediment concentrations reflecting their great bioavailability (242–3880 mg/kg dw). The highest concentration was observed in the port of the southern CASPIAN SEA (Anzali, Nowshahr and Babolsar), a location affected by intensive shipping activities.Conclusion: The distribution pattern of PAHs was similar for FISH and SEDIMENTS, particularly for SEDIMENTS characterized by high contamination level, and they were dominated by the high molecular weight PAHs (4–6-rings) which have high ecological risks.
