Distribution of oil, grease and polycyclic aromatic hydrocarbons in coastal water and sediments of Suez Bay

Abstract The permanganate index (PI), oil and grease (O&G), 17 polycyclic aromatic hydrocarbons (PAHs) were analyzed in surface sediment water samples collected at 13 sites along the western coast of Suez Bay (SB). PI O&G SB coastal seawater ranged from 9.6 mg O 2 l −1 17.0 to 16.0 37.0 , respectively. level (PAH) offshore area was determined by gas chromatography/flame ionization detection. concentration 0.574 16873.2 ng g 0.502 43.540 water. data compared with values reported literature. possible source origin pollution also assessed based on relative PAH levels study sites, ratio low molecular mass PAHs (LPAHs) high (HPAHs), indices samples.
