Abstract
To obtain the residual organochlorine pesticides in the culture environment of ginseng on Sangju, Gyeongbuk, the analytical methods for BHC isomers, Aldrin, DDE, Dieldrin, DDD, Endrin and DDT by GCECD are surveyed. The relative retention times for $\alpha$-BHC, $\beta$-BHC, ${\gamma}$-BHC, $\delta$-BHC, Aldrin, DDE, Dieldrin, DDD, Endrin and DDT were 1.000, 1.042, 1.049, 1.086, 1.202, 1.335, 1.341, 1.371, 1.391 and 1.439, respectively The BHC isomers, Aldrin, DDE, Dieldrin, DDD, Endrin and DDT were separated on the base line. The qualified detection concentration for $\alpha$-BHC, $\beta$-BHC, ${\gamma}$-BHC and $\delta$-BHC is 0.43, 1.33, 0.54 and 1.63 ng/g and it's of Aldrin, DDE, Dieldrin, DDD, Endrin and DDT were 0.63, 0.50, 0.66, 0.74, 0.96 and 0.88ng/g, respectively. BHC isomers, Aldrin, DDE, Dieldrin, DDD, Endrin and DDT were not detected in culture environment of ginseng on Sanaju, Gyeongbuk. The detection concentration for Hg, Cd, Pb, Cr, and As in ginseng were 0.0086ppm, 0.0020ppm, 0.0200ppm, 0.0271ppm and 0.0220ppm, respectively, which were also lower than the 30ppm Korea Food & Drug Administration advisory level for heavy metal in herbal medicines.
