水蒸氣蒸溜法으로 抽出하고 GLC-ECD를 使用하여 全羅南道 耕作地 土壤試料 121點(plastic film house 59, 밭 30, 果樹園 32點) 중의 6가지 有機鹽素系 殺蟲劑 (γ-BHC, heptachlor, dieldrin, p,p`-DDE, p,p`-DDD, p,p`-DDT)의 殘留分을 分析評價하였다. 總平均殘留量은 果樹園이 0.415ppm, plastic film house가 0.234ppm, 밭 土壤이 0.158ppm이었다. 全體 殘留水準의 94%를 p,p`-DDT와 그 同族體(p,p`-DDE, p,p`-DDD)가 차지했고, γ-BHC는 모든 供試土壤에서 檢出되었으며 검출범위는 trace∼0.050ppm이었다. 總 平均殘留量은 p,p`-DDD>p,p`-DDT>dieldrin◎heptachlor>γ-BHC◎p,p`-DDE 順이었다.

Agricultural soil samples collected from 121 sites (plastic film house 59, up-land 30 and orchard 32 sites) were evaluated by steam distillation and GLC-ECD analysis for organochlorine pesticides (γ-BHC, heptachlor, p,p`-DDE, dieldrin, p,p`-DDD, and p,p`-DDT) in Jeollanam-Do area. Total residues of organochlorine pesticide in orchard, plastic film house and up-land were 0.415, 0.234 and 0.156 ppm, respectively. Ninety-four percent of total residue was p,p`-DDT and its homologues (p,p`-DDE and p,p`-DDD). γ-BHC was detected in all soil samples at trace∼0.050 ppm range. Residue levels of organochlorine pesticide increased in the order of p,p`-DDE, γ-BHC, heptachlor, dieldrin, p,p`-DDT and p,p`-DDD.
