Abstract
During the last years, the oil and gas explorations, extractions and refineries have led to severe ecological damages into the sensitive environment of the Persian Gulf. In this study, the level of oil contamination, the source of hydrocarbons and the degree of weathering or degradation extent were investigated in the Surface Sediments of Pars Special Zone, Persian Gulf. Fifteen sediment samples were collected. The Gas Chromatography-Mass Spectrometry used to analyze Aliphatic Hydrocarbons (AHC) and EPA's sixteen compounds of Polycyclic Aromatic Hydrocarbons (PAHs). The total concentration of Aliphatic Hydrocarbons found to be in the range of 693 to 3752 μg/g and the 16 EPA PAHs compounds varied between 46.6 and 84.7 ng/g dry weight in the region. The concentration of hydrocarbons found to be lower than the level of threshold effects. The source of compounds was also identified by developing the multiple indices.
