Abstract

Surface sediments were collected from 32 sites in the Ambarlı Port located in the northern coast. of the Marmara Sea and analysed for 16 polycyclic aromatic hydrocarbons (PAHs) listed as the priority. pollutants by the US EPA. Total concentrations of the PAHs ranged from 56 to 3685 ng/g, dry weight, and the highest values were recorded at the coast locations, and the anchoring areas. Source analysis using the isomer ratios suggested that the PAHs in the Ambarlı Port area sediments were derived to a mixture of the pyrolytic input coming from anthropogenic combustion processes such as industry, vehicles and heating processes. Further, the carcinogenic PAH levels at the near shore and anchoring areas around the Ambarlı Port were exceeded the effect range low (ERL), and could cause the acute biological impairments when compared to the sediment quality quidelines.

Keywords: Polycyclic aromatic hydrocarbons, Surficial marine sediment, Ambarlı Port, Diagnostic ratio, Sediment Quality Guidelines.
