Abstract

This study was conducted to evaluate the safety of 208 types of residue pesticides on 150 dried agricultural products in Ulsan. The pesticide residues were detected using GC-MS/MS, LC-MS/MS, GC/ECD, GC/NPD, and LC/PDA. The detection rate was 19.3% (29 of 150 samples), and 28 types of pesticides were detected. Two of the 29 pesticide residues exceeded the maximum residue limit (MRL). Difenoconazole was detected in Ulleungdo aster, and chlorothalonil and chlorpyrifos were detected in chili pepper leaves. In the vegetable group, the frequency of pesticide residues was found to be the highest in dried leafy vegetables, followed by dried fruiting vegetables other than cucurbit vegetables, and then dried stalk and stem vegetables. The pesticide types detected in the commercial dried agricultural products were fungicide (60%), insecticide (23.8%), and acaricide (16.3%). In the validation study, the values of limit of detection (LOD), limit of quantitation (LOQ), coefficient of determination (R2), and recovery rate were in the range of 0.0001-0.0409 mg/kg, 0.0003-0.1241 mg/kg, 0.994-0.999, and 81.58-116.79%, respectively. The ratio of estimated daily intake (EDI)/acceptable daily intake (ADI) was 0.00002-0.31395%.

본 연구에서는 울산지역에서 유통되는 건조농산물의 잔류농약 실태를 조사하기 위해 150건을 수거하여 잔류농약 분석을 실시하였다. 잔류농약 208항목을 식품공전 다성분 분석법을 이용하여 실시하였으며 29건(19.3%)에서 잔류농약이 검출되었다. 품목별로 분류하면 고추 품목에서 7건, 취나물에서 4건, 곤드레에서 3건, 대추, 무(잎), 가지에서 각 2건, 귤, 부지깽이, 고구마줄기, 여주, 고사리, 무(뿌리), 사과, 감잎차, 고추잎에서 각 1건씩 검출되었다. 검출된 잔류농약을 성분별로 분류하면 살균제성분이 60%, 살충제성분이 23.8%, 살충제, 살비제로 작용하는 성분이 16.3% 검출되어 살균제가 가장 많이 검출되었다. 가장 많이 검출된 잔류농약은 Tebuconazole, Pyraclostrobin, Difenoconazole, Azoxystrobin이다. 분석결과 2건에서 3항목의 잔류농약이 잔류허용기준을 초과하여 부적합으로 판정되었으나, 위해도 평가결과 0.00002-0.3140%범위로 나타나 모두 안전한 것으로 판단되었다.
