A multiresidue, simple and rapid isolation technique known as matrix-solid phase dispersoin (MSPD) for the extraction and quantitative gas chromatographic/electron capture detection (GC/ECD) determination of 14 organochlorinated pesticides(α-BHC, β-BHC, y-BHC, aidrin, diel-drin, endrin, heptachlor, α-endosulfan, β-endosulfan, endosulfan sulfate, p,p`-DDE, o,p`-DDD, p,p`-DDD, p,p`-DDT) from meat fats. The 14 pesticide were fortified into meat fat(O.5g) and blend with 2g C(18). (C(18)/meat fat matrix blend and 2g activated florisil comprise an extraction column from which the pesticides are eluted by adding 8m1 acetonitrile. Then 2μe of the eluate is analyzed by GC/ECD. Unfortified blank controls are tested similarly. The eluate contained all the pesticide analytes and was free of interfering coextractants. Recovery rate(31.3-500ngIg) were ranged from 80± 4% to 97± 4%. Any organochlorinated pesticides were not detected in 120 samples of beef and pork collected from slaughter houses in Kyeonggi province.
