Abstract

One hundred and twenty-five samples comprising thirteen vegetables harvested in 1971 were collected and subjected to GLC analysis, for ${\alpha}-and\;{\gamma}-BHC$ residues, using ECD. Heavy dependence on the technical BHC, instead of Lindane, was amply reflected on the BHC residues-residues of ${\alpha}-BHC$, depending on the vegetables, amounted to $2{\sim}7$ times that of ${\gamma}-BHC$. In spite of extensive contamination by the BHC isomers, residue levels of ${\gamma}-BHC$ were less than 0.015 ppm in all vegetables and were far less than the tolerence limit of $0{\sim}3.0ppm$ recommended jointly by the FAO and WHO.

1971년도(年度) 국내(國內)에서 생산(生産)된 13종(種)의 채소(菜蔬) 125점(點)을 괴집하여 ${\alpha}-$${\gamma}-BHC$의 잔류수준(殘留水準)을 GLC로 분석(分析)하였다. ${\gamma}-BHC$의 잔류분(殘留分)은 채소별(菜蔬別)로 차이(差異)는 있었으나 평균(平均) 0.015ppm을 초과(超過)하지 않았다. ${\alpha}-BHC$의 잔류분(殘留分)은 채소(菜蔬)의 종류(種類)에 따라 ${\gamma}-BHC$$2{\sim}7$배(倍)에 달(達)하였으나, 13종(種)의 채소(菜蔬) 모두 0.030ppm을 넘지 않았다. ${\gamma}-BHC$의 잔류수준(殘留水準)은 FAO/WHO공동위원회(共同委員會)에서 검사(檢討) 결정(決定)한 Tolerence에는 미달(未達)하나, 현용(現用) BHC원제(原劑)를 Lindane정제(製劑)로 대체(代替)할 것을 제안(提案)하였다.
