Abstract
Milk and dairy products are an important exposure route for organochlorine pesticides (OCPs) to humans. For this reason milk, kareish cheese and yoghurt analyzed for the presence of fourteen organochlorine pesticides namely Alpha HCH, Gamma HCH, Delta HCH, Aldrin, Gamma Chlordane, Endosulfan, Dieldrin, Endrin, , p,p'-DDE, p,p'-DDD, p,p'-DDT and methoxychlor using gas chromatography with electron capture detector (GC-ECD. A total of 90 random samples of raw cow's milk samples and dairy products (30 of each) were collected from 4 districts in Fayoum Governorate (Fayoum, Etssa, senoris and Tamia) during a period from September 2017 to January 2018. The results indicated that 6.60%(6/90) , 5.50%(5/90), 25.55%(23/90), 13.33%(12/9), 11.11%(10/90), 1.11%(1/90), 18.88%(17/90), 8.88%(8/90), 15.55%(14/90), 17.77%(16/90) and 22.22%(20/90) of the examined samples were contaminated with Alpha HCH, Gamma HCH, Delta HCH, Aldrin, Gamma Chlordane, Endosulfan, Dieldrin, Endrin, p,p'-DDE, p,p'-DDD and methoxychlor,respectively. None of the examined samples revealed the presence of Dichlorodiphenyltrichloroethane (p,p'-DDT), Heptachlor and Heptachlor epoxide. Generally the concentrations in the examined samples followed the order of Delta HCH > methoxychlor > Gamma HCH > p,p'-DDD > Dieldrin > Aldrin > Gamma Chlordane > Endosulfan > p,p'-DDE > Endrin > Alpha HCH.
