Residues of some organo-chlorine pesticides on 108 solis collected from 5 sites of Chungnam avea during March 20-April 6, 1986 were investigated. 12 different kinds of Chemical components were detected showing the highest detection frequency with P.P`-DDE(67.6%) and the lowest with Heptachlor(1.8%). 4 different chemicals, α-BHC, γ-chlordane, P.P`-DDD and P.P`-DDD and P.P`-DDE showed their average contents in the soils of 0.001 ppm and 0.005ppm for β-BHC, respectively. On the other hand, α-BHC, γ-chlordane, P.P`-DDT. O.P`-DDT and P.P`-DDD showed 0.002ppm for their average contents of residues, respectively.
