Abstract

The reduction factor of pesticides is getting more crucial these days. However, most studies have focused on the relationship between pesticides and commodities. This study was conducted to examine the pesticide reduction factor based on their physicochemical properties. Five pesticides were selected among 288 insecticides by considering the presence of an ionizable group, the log P, and boiling points. The correlation coefficients between log P and removal by tap water, 5% acetic acid, 20% ethanol, and 0.15% detergent were -0.835 (p<0.001), 0.336 (p=0.221), 0.659 (p<0.01), and -0.939 (p<0.001), respectively. Removal by blanching was affected by log P as it showed a positive correlation with a log P of 0.620 (p<0.05). Removal by frying showed a strong negative correlation with a log P of -0.913 (p<0.001). The results suggest that removing pesticides was affected largely by log P and by vapor pressure during cooking, whereas during washing, the matrix of the food also contributed to the reduction.

농약을 안전하게 관리하는데 사용되는 지표인 농약의 잔류허용기준의 결정요인 중 하나인 감소계수에 대한 연구는 최근에 더욱 요구도가 높아지고 있다. 그러나 기존의 연구들은 농산물별, 농약별로 이루어져 효율적인 데이터베이스 구축에는 적합하지 못하다. 이에 본 연구는 농약의 감소계수를 농약의 물리화학적 특성에 따라 산출하고자 실험을 계획하였다. 먼저 농약잔류허용기준이 설정된 288개의 농약을 대상으로 하여 이온화그룹포함여부, log P, 끓는점에 따라 propamocarb, azoxystrobin, fenarimol, dichlorvos, edifenphos, cypermethrin, fenvalerate의 농약을 선별하였다. 이 중 회수율과 농약의 전처리과정에서 실험이 어려웠던 propamocarb와 azoxystrobin은 최종 데이터 분석에서 제외하였다. 해당 농약들을 수돗물, 5% 아세트산 수용액, 20% 에탄올 수용액, 0.15% 세제액의 4가지의 세척방법과 데치기, 튀기기 2가지의 조리방법 총 6가지의 조건을 처리하여 Pearson 상관분석을 하였다. 그 결과, log P와의 상관성에 있어 5% 아세트산 수용액은 0.336(p=0.221)로 유의적인 상관성이 없었으나, 수돗물에서의 세척은 -0.835(p<0.001), 20% alcohol solution에서는 -0.659(p<0.01), 세제세척에서는 -0.939(p<0.001)의 값을 얻었다. 데치기와 끓는점은 유의적인 상관성을 보이지 않았으며, log P와는 0.620(p<0.05)로 유의적인 양의 상관관계를 보였다. 튀기기와 끓는점은 상관성이 있으나, 이보다는 log P와의 상관성이 -0.913(p<0.001)로 더 큼을 확인할 수 있었다. 이를 통해 세척과정에 있어서는 농약의 잔류에는 단순히 농약자체의 수용성 뿐 아니라 작물의 침투성도 관계가 있음을 확인할 수 있었다. 반면, 조리과정에 있어서는 농약의 잔류에는 log P와 끓는점이 보다 높은 상관관계를 가짐을 확인할 수 있었다.
