Raw buffalo milk samples from the agroindustrial zone in upper Egypt were analyzed for the presence of organochlorine and organophosphorus pesticides using gas chromatography-mass spectroscopy. Five organochlorine pesticides namely, alachlor, dieldrin, hexachlorobenzene, lindane and methoxychlor and three organophosphorus pesticides chlorpyrifos, malathion, and parathion-methyl were detected in the milk samples. In 44% of the samples, the concentrations of lindane and malathion residues exceeded tolerance levels set by the European Commission (EC) in 2008. In addition, the concentrations of chlorpyrifos, methoxychlor, and hexachlorobenzene residues exceeded the 2008 EC maximum residual limits (MRLs) by 33, 66, and 88% of the examined samples, respectively. However, the levels of alachlor, dieldrin, and parathion-methyl residues were below EC MRLs. The results of this study confirm the risks of pesticide residues exposure that threaten consumer health in Egypt. Thus, we recommend that pesticide residue monitoring programs be instituted in all the developing countries.
对埃及北部农业工业区的生水牛乳样本进行了气相色谱-质谱分析，以检测有机氯和有机磷农药的存在。在牛奶样本中检测到 5 种有机氯农药，分别为甲草胺、狄氏剂、六氯苯、林丹和甲氧氯；3 种有机磷农药，分别为氯吡硫磷、马拉硫磷和甲基对硫磷。在 44%的样本中，林丹和马拉硫磷的残留浓度超过了欧盟委员会（EC）2008 年设定的允许限量。此外，氯吡硫磷、甲氧氯和六氯苯残留浓度分别超过 2008 年 EC 最大残留限量（MRL）的 33%、66%和 88%。然而，甲草胺、狄氏剂和甲基对硫磷残留水平低于 EC MRL。本研究结果证实了农药残留暴露的风险，这对埃及消费者的健康构成威胁。因此，我们建议在所有发展中国家建立农药残留监测计划。
