Abstract

Background and purpose: The CASPIAN SEA as a largest lake in the world has always been exposed to many kind of pollutants caused by population density, industrial and agricultural activities along the coastal areas. Undesirable effects of pollutant on aquatic life, human and public health call for periodic assessment of contamination for coastal environment management.Materials and methods: In this study, sediment and Gammarus spp samples were evaluated at 11 sampling sites on the Southwest coastline of the CASPIAN SEA in GUILAN PROVINCE. To measure hydrocarbon components, the samples were extracted by a Soxhlet extractor and 16 PAHS components in sediment and biota specimens were analyzed using Agilent GC-MS.Results: Total mean concentrations of PAHS in sediment and living samples were 19.8 ng/g and 35.4 ng/g, respectively. The results showed that in 16 component of PAHS, the concentration of naphthalene at all sites was higher (10-35%) than the others. PAHS compounds diagnostic ratios for the identification of contamination sources illustrated that PAHS pollution in the region are originating from pyrogenic and petrogenic bases.Conclusion: Risk assessment of sediment toxicity showed that according to international sediment quality guidelines, the mean level of total PAHS at all stations were in low range and some compounds were moderately polluted. These levels of sediment pollution are not serious threat for the region in near future.
