Persistent organic pollutants (POPs) such as polycyclic aromatic hydrocarbons (PAHs) are of great concern due to their persistence, bioaccumulation and toxic effects. In this study, water samples were collected in four seasons during 2011-2012 from nine catchment areas that represent the aquatic environment of Ismailia canal in Egypt. The distribution of 16 PAHs included in the US Environmental Protection Agency's (EPA) priority pollutant list was analyzed by gas chromatography/flame ionization

Total PAH concentrations ranged from 1822 to 13170 ng/L in summer samples, for autumn the concentrations were in the range 866 to 5217 ng/L, for spring the concentrations were in the range 697 to 5960 ng/L, and for winter concentrations ranged from 926 to 5217 ng/L. The PAH profiles were dominated by low molecular weight PAHs (two-and three-ring components) in all collected water samples. The origin of PAHs in all water samples in this study areas may be from oil or other industrial contamination.
