제주도의 중요한 채소재배지의 토양과 농작물에 대한 BHC제 및 heptachlor제의 잔류수준을 1979.10-1980.11. 사이에 조사하였다. 토양중에서의 ${alpha}-BHC$는 n.d-0.967ppm(평균 : 0.391ppm), ${gamma}-BHC$는 n.d-0.590ppm(평균 : 0.218ppm), heptachlor는 n.d-0.819ppm(평균 : 0.163ppm), 그리고 heptachlor epoxide는 n.d-0.256ppm(평균 : 0.034 ppm) 잔류하였으며 채소작물중 배추의 평균잔류량은 ${alpha}-BHC$ 0.002ppm, ${gamma}-BHC$ 0.001ppm, heptachlor 0.002ppm, heptachlor epoxide, 0.001 ppm이며, 당근의 경우에는 ${gamma}-BHC$ 0.004ppm, ${alpha}-BHC$ 0.012ppm, heptachlor 0.003ppm, heptachlor epoxide 0.011ppm이었으며 마늘에는 ${alpha}-BHC$ 0.014ppm, ${gamma}-BHC$ 0.007ppm, heptachlor 0.002ppm 그리고 heptachlor epoxide는 trace로 나타났다.
Residues of some organochlorine insecticides ${alpha}-BHC$, ${gamma}-BHC$, heptachlor and heptachlor epoxide of field soils and vegetables in Jeju island were investigated from october, 1979 to november, 1980. Residues in soil ranged in n.d-0.967 (aver.; 0.391) ppm for ${alpha}-BHC$, n.d-0.590 (aver.; 0.218) ppm for ${gamma}-BHC$, n.d-0.819 (aver.; 0.163) ppm for heptachlor, and n.d.-0.256 (aver.; 0.034)ppm for heptachlor epoxide. Average residue levels in cabbage were 0.002ppm for ${alpha}-BHC$, 0.001ppm for ${gamma}-BHC$, 0.002 ppm for heptachlor, and 0.001ppm for heptachlor epoxide. The levels of the same chemicals were 0.012ppm, 0.004ppm, 0.003ppm and 0.011ppm on carrot, and 0.014 ppm, 0.007ppm, 0.002ppm and trace on garlic, respectively.
