Abstract

To obtain the residual organochlorine pesticides in the coastal environment, the methods of analysis for BHC's isomer, Kelthane, Orthocide and Endrin by GC-ECD are surveyed. The relative retention time for ${\alpha}$-BHC, ${\beta}$-BHC, (equation omitted)-BHC and $\delta$-BHC is 1.00, 1.18, 1.24, 1.31 and it's of Kelthane, Orthocide, Endrin is 1.56, 1.70, and 2.02, respectively. The BHC isomers Kelthane, Orthocide and Endrin are separated on the base line. The plate height(H) for ${\alpha}$-BHC, ${\beta}$-BHC, (equction omitted)-BHC and $\delta$-BHC is 50mm, 35mm, 32mm and 29mm, and it's of Kelthane, Orthocide, Endrin is 81mm, 68mm and 48mm, respectively. The qualified defection concentration for ${\alpha}$-BHC, ${\beta}$-BHC, (equation omitted)-BHC and $\delta$-BHC is 0.26, 0.36, 0.37 and 0.39ng/g and it's of Kelthane, Orthocide, Endrin is 0.55, 1.39 and 0.56ng/g, respectively, BHC's isomer, Kelthane, Orthocide and Endrin are not detected in soil environment on South Cheju Island. Also residual organochlorine pesticides are not detected in the sea water and sediment in the ocean environment.
