Distribution and Sources of Polycyclic Aromatic Hydrocarbons in the Sediment of Bushehr Coastal Zone-Iran

Polycyclic aromatic hydrocarbons (PAHs) concentrations in sediments were measured from five stations in coastal area of Bushehr-Iran. Total PAHs concentration ranged from 844.9 to 4790.3 ng g-1 in summer and 935.0 to 4972.0 ng g in winter. Significant difference was observed between total PAHs concentration in studied stations (P<0.05). Among the studied stations, tPAHs concentration was higher in Rafael followed by Sheghab station. The lowest level of tPAHs observed in Abshirinkon station. There wasno significant difference between tPAHs concentration in August and February (P>0.05). Based on the numberof aromatic rings in the molecular structure, the composition pattern of PAHs was different within studiedstations. The studied stations received their PAHs from both petrogenic and pyrolitic sources. The level of PAHs contamination in the Bushehr coastline founded to be moderate to high compared to other studied locations. Regular monitoring of PAHs contaminant in the region is recommended
