Abstract
The possibility of multiresidue analysis of 24 pesticides out of 30 residual pesticides which are subjected to test in the golf courses was examined. The utility of multiresidue method for pesticide residue test was evaluated by recovery test through a standard addition method of pesticides in water, soil, and lawn grass. The experimental results of the recovery test for individual pesticides are as follows : The number of pesticide of which average recovery rate was over 70% regardless of media was 16 pesticides. These pesticides were composed of 8 organophosphorus pesticides (chlorpyrifos, chlorpyrifosmethyl, diazinon, EPN, fenitrothion, phenthoate, phosalone, and toclofos-methyl). 4-organochlorinated pesticides (daconil, captan, endosulfan, and tetradifon), 2-pyrethroid pesticides(fenpropathrin, lambda-cyhalothrin) and 2 other pesticides (bromopropylate, pendimethalin). On the other hand, in case of dicofol, average recovery rate was over 70% for water and lawn grass but only 53.3% for soil. Therefore, the multiresidue method applied in this experiment is not appropriate for analysis of dicofol in soil. Furthermore, among 7 pesticides, 2 pesticides(amitraz and pyraclofos) showed that theirs average recovery rate deviated from criteria($70{\sim}130%$) in almost ail media, while 5 pesticides(bensulide, deltamethrin, iprodione, phosphamidon and tralomethlin) were not detected from all media by GC/NPD or GC/ECD.

다성분 동시분석방법의 적용성을 검토하기 위하여 골프장 농약잔류량검사 대상항목 30종 중 다성분 동시분석이 가능할 것으로 판단되는 24종(유기인계 농약 11종, 유기염소계 농약 5종, 합성피레스로이드계 농약 4종 및 기타 농약 4종 및 농약성분에 대한 토양 잔디 물 등 매체별 회수율 실험 결과, 다성분 동시분석방법의 적용이 가능한 농약은 16종이었으며, 모든 매체에서 70% 이상의 회수율을 보였다. 이들 농약을 계통별로 분류하면, 유기인계 농약 8종(chlorpyrifos, chlorpyrifos-methyl, diazinon, EPN, fenitrothion, phenthoate, phosalone, and toclofos-methyl), 유기염소계 농약 4종(daconil, captan, endosulfan, and tetradifon), 합성피레스로이드계 농약 2종(fepropathrin, lambda-cyhalothrin), 기타 농약 2종(bromopropylate, pendimethalin)이었다. 다성분 동시분석방법의 적용 할 수 없는 8종의 농약 중 dicofol의 경우는, 물과 잔디에서는 회수율이 70%를 상회하였으나, 토양에서는 53%로 나타나 토양의 경우 다성분 동시분석방법의 적용은 어려운 것으로 판단되었다. 또한 amitraz는 매체별 회수율이 70% 이하였고, pyraclofos는 매체별 평균 회수율이 다성분 동시분석방법 적용기준($70{\sim}130%$)에 벗어났으며, bensulide, deltamethrin, iprodione, phosphamidon, tralomethlin의 농약은 전혀 검출되지 않아 본 연구에서 사용한 다성분 동시분석방법을 적용할 수 없었다.
