RESUMEN
Organochlorine compounds were analyzed in three species of fish [Bouri, Moza, and Mousa], from three Egyptian areas [Suez, Hurghada and Marsa Alam]. Although all fish studied are bottom or near-bottom feeders, remarkable variations in concentrations between studied species were noticed The MPI values recorded at the studied cities were in descending order: Bouri > Moza> Mousa. The highest concentration of pesticides was recorded in Suez Governorate fish [113.9 ng/g of dry weight] and the pp-DDE dominated over the other pp-isomers in all studied fish, while aldrin was the dominated in the studied cyclodiene compounds. However, hexachlorobenzene [HCB] was present in all the studied fish. Toxaphene was detected in all fish collected from Suez to Marsa Alam areas. Chlordane was not detected in fish from Marsa Alam. The level of organochlorine pesticides contamination in fish from the studied areas is relatively low and should not pose a health risk to consumers
