ABSTRACT: The concentrations of 13 polycyclic aromatic hydrocarbons (PAHs) in water, sediment and fish samples collected from 6 locations in El-Menofiya governorate, Egypt were analyzed. Concentrations of total 13 PAHs in water samples ranged from 226.9 ng l at El Sarsawia canal to 1492.2 ng l at El -1 -1 Menofi drain, which were predominated by three-and four-ring PAHs. The total PAHs concentration in sediments samples ranged from 1197.79 ng g dry weight at Bahr Shebin canal to 2701.55 ng g dry -1 -1 weight at El Embaby drain, while it ranged in fish samples from 371.68 ng g wet weight at El Sarsawia -1 canal to 2019.25 ng g wet weight at Bahr Shebin canal. Four-and five-ring were the dominant species -1 in sediment and fish samples. Ratios of specific PAH compound including Phenantharene / Anthracene and Fluoranthene / Pyrene were calculated to evaluate the possible sources of PAHs contamination. These ratios reflect a pyrolytic input of PAHs in the area under study.
