ACCORDING to the IMO declaration, the Gulf area is the most sensitive and oil-polluted area in the world. Sediment samples were collected from five stations at different distances along discharge basin of Suez Oil petroleum Company (SOPC), in 2012-2013 and the concentrations of poly-aromatic hydrocarbons were determined by HPLC analysis. The concentrations of ΣPAHs were higher than the guideline value 4022 ng/g, due to the aromatic outlet to discharge basin. The concentration of PAHs in the sediments ranged between 22333.983 and 73597.864 ng/g. dry weights with 43016.278 ng/g. dry weights as the average concentration was greater than the guideline; thus, the study area is classified highly polluted. Concentration of the most PAH components were above the ER-L,ER-M, TEL and PEL values in all the sampling stations. The PAHs profiles showed that the Ʃ 2-3&4 rings compounds were the major PAHs detected in discharge basin of SOPC. Characteristic ratios of Ant/ (Ant+ Phe), and Flu/ (Flu + Pyr) indicated that PAHs could originate from petrogenic and pyrolytic sources. Petroleum contamination associated with increased industrial processes beside, continuous discharge of the refinery’s effluents related by oily smuggling with water to bottom sediments of the discharge basin, without completely treated or degraded easily through weathering processing, which can have side-effects on the ecosystems and human safety, must be controlled.
