To obtain the residual organochlorine pesticides in the ginseng, the methods of multi-analysis for BHC’s isomer, DDT’s isomer and other organochlorine pesticides by GC-ECD are surveyed. The relative retention time for is 1.000, 1.025, 1.034 and 1.056, respectively. The relative retention time for o,p-DDE, p,p-DDE, o,o-DDD, o,p-DDT, o,p-DDD, and p,p-DDT is 1.199, 1.230, 1.242, 1.286, 1.329 and 1.333, respectively. The BHC isomers, DDT’s isomer and other organochlorine pesticides are separated with multianalysis condition. The qualified defection concentration for , Quintozene, Aldrin, Captan, , and Dieldrin is 0.95ng/g, 0.27ng/g, 1.04ng/g, 0.63ng/g, 0.55ng/g and 0.62ng/g, respectively. The qualified defection concentration for Fenhexamid, Endrin, , o,p-DDT, Endosulfan-sulfate is 5.71ng/g, 0.61ng/g, 0.48ng/g, 0.44ng/g and 0.51ng/g, respectively. BHC, Aldrin, Dieldrin, Endrin and DDT, which were Korea Food & Drug Administration advisory pesticides, are not detected in soil environment. Also it’s residual organochlorine pesticides are not polluted in the ginseng on Sangju Korea.
