Survey on the Level of Organochlorine Pesticide Residues in Agricultural Products

농산물중 유기염소계 농약의 잔류수준

This study was carried out for the dietary safety based on the level of pesticide residues in 19 kinds of agricultural products consumed in Kangwon-do, Korea. From April 1995 to December 1997, eight organochlorine pesticides in 673 samples were analyzed by using GLC-ECD. According to the results, one kind of pesticides were detected in 159(23.6%) samples and two kinds were in 24(15.1%). While Chlorobenzilate, Dicofol and Tetradifon were not found. Detection ranges of pesticides were $0.001{\sim}0.117ppm$ for DDT, $0.001{\sim}0.095ppm$ for ${\gamma}-BHC$, $0.001{\sim}0.067ppm$ for ${\alpha},{\beta}-Endosulfan$, $0.003{\sim}0.250ppm$ for Chlorothalonil and 0.033ppm for Captafol. Average residues were 0.006ppm for DDT, 0.009ppm for ${\gamma}-BHC$, 0.008ppm for ${\alpha},{\beta}-Endosulfan$, 0.024ppm for Chlorothalonil and 0.033ppm for Captafol, respectively. Consequently, all of the organochlorine pesticide residues in the analyzed samples were within the maximum residue limits.

1995년 4월부터 1997년 12월까지 약 3년간에 걸쳐 강원도지역에 납품되어 급식된 19종 농산물에 대하여 농산물의 안전성을 확보하고 보건 위생상의 위해를 예방하기 위한 기초 자료로 활용하기 위하여 검사를 수행하였다. 유기염소계 8종을 ECD가 부착된 Gas Chromatography에 의하여 다음과 같은 결과를 얻었다. 1. 농산물 673건중 유기염소계 농약이 159건(23.6%)에서 검출되었으며, 이중 2종류의 농약이 검출된 농산물은 24건(15.1%)이었다. 2. Chlorobenzilate, Dicofol 및 Tetradifon는 전 시료에서 검출되지 않았다. 3. 농약의 검출범위는 DDT $0.001{\sim}0.117ppm$, ${\gamma}-BHC$ $0.001{\sim}0.095ppm$, ${\alpha},{\beta}-Endosulfan$ $0.001{\sim}0.067ppm$, Chlorothalonil $0.003{\sim}0.250ppm$, Captafol 0.033ppm이었다. 4. 각 농약의 평균 잔류량은 DDT 0.006ppm, ${\gamma}-BHC$ 0.009ppm, ${\alpha},{\beta}-Endosulfan$ 0.008ppm, Chlorothalonil 0.024ppm, Captafol 0.033ppm이었다. 단 잔류 허용 기준을 초과하는 농산물은 1건도 없었다.
