Abstract

Establishment of simultaneous analysis method and monitoring for individually analyzing residual eight ergosterol biosynthesis inhibitors, EBI (difenoconazole, diniconazole, fenarimol, fenbuconazole, hexaconazole, myclobutanil, nuarimol and paclobutrazol) pesticides in commercial agricultural products, were conducted. The simultaneous analysis method for the pesticides was established using a GC/MS/MS for EBI pesticides. Residual amount of those pesticides were investigated in 989 commercial agricultural products (fifteen kinds of cereal grains, vegetables, beans, nuts, fruits and mushrooms) from seven metropolitan cities and eight provinces. In EBI pesticides analysis, linearity of GC/MS/MS analysis was 0.9974-0.9992, and that of recoveries were 86-135% with relative standard deviations (RSD) <20%. The limit of quantification (LOQ) of the method ranged from 0.5 to 5.0 mg/kg for eight EBI pesticides. According to the monitoring of the EBI pesticides in commercial agricultural products, difenoconazole, fenarimol, hexaconazole showed various residual levels (total frequency of 8/989 detection, 0.8%). Paclobutrazole showed in excess levels of the MRLs (maximum residue limits) for pesticides in one chard sample by the Korea Food Code. As a result of exposure assessment on the detected 8 individual pesticides, all pesticides (difenoconazole, fenarimol, hexaconazole, paclobutrazole) were evaluated as safe level in comparison to toxicologically acceptable daily intake.

우리 국민의 주식이 되는 쌀(백미)과 콩류, 감귤류, 열대과 일류, 엽채류, 엽경채류, 근채류, 과채류, 버섯류에 속하는 농산물(989건)에 대해 8종의 EBI계 농약의 잔류 여부를 분석하였다. 그 결과 8건의 검체에서 농약이 검출되었고 농약 수는 5종이 검출되었다. 기준 미설정 농약은 2종이었으며, 곡류 134건 중 4건 검출로 3.0%, 채소류 471건 중 4건 검출로 0.8%의 검출율을 나타내었다. 그 외 콩류(48건), 견과종실류(72건), 과실류(197건), 버섯류(67건)에서는 전혀 검출되지 않았으며 부적합율은 0.1%로 나타났다. 국내 미등록농약인 paclobutrazole이 근대에서 잠정허용기준을 초과하는 것으로 확인되었다. 그리고 EBI계의 검출율은 0.8%로 매우 낮았으며 검출된 농약의 경우도 기준규격 이하로 안전한 수준이었다.
