The aim of the research was to establish the level of organochlorine pesticides residues (αHCH, β-HCH, γ-HCH (Lindan), DDT-T, Heptaclor, Dieldrin, Endrin) in the raw milk used for cheese production. Sixty samples of milk were analyzed, using the gas-chromatographic method from AOAC (Association of Official Analytical Chemists). Thus, the pesticides residues from milk fat or from the ether extract of the sample were selectively extracted with acetonitril and petroleum ether and purified on florisil column and than eluted with petroleum ether, diethyl ether and ethanol mixture.Â
