    Abstract:
    The residues of 19 EPA-organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) were determined in water samples collected from the near-shore surface water of Alexandria coast, Egypt, using gas chomatograph-electron capture detector (GC-ECD) and gas chromatograph-mass spectometer (GC-MS). Higher concentrations of hexachlorocyclohexane (HCH)s, TC, and 2,2-bis (p-chlorophenyl)-1,1,1-trichloroethane (DDT)s with 1.36, 0.556, and 36.97 ngl(-1) were recorded, respectively, with a maximum of 165.46 ngl(-1) of PCBs during June 2014, which was clearly affected by higher sewage activities during summer season. Among DDTs metabolites, p,p-DDT was the most dominant with a maximum of 36.31 ngl(-1) recorded at El-Montazah station during June 2014.
