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.
采用气相色谱 - 电子捕获检测器（GC - ECD）和气相色谱 - 质谱仪（GC - MS），对从埃及亚历山大港海岸近岸地表水采集的水样中的19种环保署有机氯农药（OCPs）和多氯联苯（PCBs）残留进行了测定。分别记录到较高浓度的六氯环己烷（HCHs）、总氯（TC）和2,2 - 双（对氯苯基）-1,1,1 - 三氯乙烷（DDTs），浓度分别为1.36、0.556和36.97 ng l⁻¹，2014年6月多氯联苯的最高浓度为165.46 ng l⁻¹，这明显受到夏季较高污水排放活动的影响。在滴滴涕代谢物中，p,p - DDT最为主要，2014年6月在蒙塔扎站记录到的最高浓度为36.31 ng l⁻¹。
