Residues of organochlorine pesticides (OC's) were analyzed by capillary GLC, using a varian 3400-ECD in sediment samples from Northern Off-Nile Delta Mediterranean Sea Coast. As a general trend the components levels were below 45 ng/g, excluding the anomalously high figure in samples. Remarkable variations in OC's concentrations were noted amongst locations, mostly due to cyclodienes followed by hexachlorocyclohexane (HCH's) and DDTs. The OC's concentrations were Extractable Organic Matter (EOM) dependent, with most polluted locations occurring past Rosetta Nile Branch mouth.
