For decades, the use of organochlorine (OC) pesticides has had a detrimental effect on the environment and human health. Contamination of soil, water, and air has also resulted in contaminated milk.
The purpose of this study was to investigate if any OC residues dichlorodiphenyltrichloroethane (DDT, Dieldrin, Endrin, and Lindane) were present in raw bovine milk from West Delta, Egypt.
200 fresh raw cow milk samples (500 ml of each sample) collected from three different governorates, west Delta, Egypt, for determination of OC pesticides residues using gas chromatography with an Agilent 6890A model gas chromatograph equipped with a 63Ni microelectron capture detector.
The obtained results revealed that åDDT, dieldrin, endrin, and lindane were detected in Alexandria, Behera, and Matrouh at incidence levels (22.7%, 30.7%, and 10%), (20%, 20%, and 16%), (9.33%, 13.3%, and 16%), and (12%, 10.7%, and 14%) with mean values of 232.2 ± 163.6, 156.4 ± 134.6 and 100.4 ± 85.9; 91.3 ± 61.2, 95.3 ± 59.8 and 57.6 ± 3.33; 15.7± 3.86, 15.1 ± 3.96 and 20.1 ± 7.33; 33.7 ± 10.6, 36.9 ± 5.51 and 52.2 ± 21.8 ng/g fat, respectively. El-Behera was the most contaminated province with an incidence level of 53.3% with a mean value of 136.8 ± 128.0 ng/g fat, followed by Alexandria at 44% with a mean value of 173.7 ± 155.5 ng/g fat, and finally, Matrouh 40% with a mean value of 74.5 ± 56.5 ng/g fat.
This research demonstrated that milk samples contain varying levels of OC pesticide residues, which can be hazardous to consumer health. Therefore, to safeguard consumers, especially children, and the elderly, OC pesticide residues in milk must be closely monitored.
几十年来，有机氯（OC）农药的使用对环境和人类健康造成了有害影响。土壤、水和空气的污染也导致了受污染的牛奶。
本研究旨在调查埃及西部三角洲的新鲜生牛乳中是否存在有机氯农药残留（滴滴涕、狄氏剂、艾氏剂和林丹）。
从埃及西部三角洲的三个不同省份（亚历山大、贝赫尔和马特鲁）采集了 200 份新鲜生牛乳（每份 500 毫升）样本，使用配备有 63Ni 微电子捕获检测器的安捷伦 6890A 型气相色谱仪，通过气相色谱法测定 OC 农药残留量。
研究结果显示，在亚历山大、贝赫尔和马特鲁，滴滴涕、狄氏剂、艾氏剂和林丹的检出率分别为 22.7%、30.7%和 10%、20%、20%和 16%、9.33%、13.3%和 16%、12%、10.7%和 14%，平均值分别为 232.2 ± 163.6、156.4 ± 134.6 和 100.4 ± 85.9、91.3 ± 61.2、95.3 ± 59.8 和 57.6 ± 3.33、15.7± 3.86、15.1 ± 3.96 和 20.1 ± 7.33、33.7 ± 10.6、36.9 ± 5.51 和 52.2 ± 21.8ng/g 脂肪。贝赫尔省的污染最严重，检出率为 53.3%，平均值为 136.8 ± 128.0ng/g 脂肪，其次是亚历山大省，检出率为 44%，平均值为 173.7 ± 155.5ng/g 脂肪，最后是马特鲁省，检出率为 40%，平均值为 74.5 ± 56.5ng/g 脂肪。
本研究表明，牛奶样本中含有不同水平的有机氯农药残留，这可能对消费者健康构成危害。因此，为了保护消费者，特别是儿童和老年人的健康，必须密切监测牛奶中的有机氯农药残留。
