초록

본 연구는 소면적 재배작물인 퀴노아 및 팥 노지 조건에서 처리된 살균제 dimethomorph에 대한 잔류특성및 안전성 평가를 위해 수행되었다 . 퀴노아는 수확 전 30, 21, 14, 7일 팥은 29, 21, 14, 6, 0일에 3회 경엽처리 하였으며 , 최종 약제 처리 후 일시 수확하였다 . 퀴노아 및 팥에 대한 잔류농약 시험방법은 QuEChERS 전처리와 LC-MS/ MS를 이용하였으며 , 회수율 89.1~109.0%, 변이계수 1.8~7.3%, 정량한계 0.01 mg kg-1로 시험방법의 적합성을 판단하였다 . 퀴노아와 팥 중 dimethomorph의 잔류량은 각각 <0.01-3.64 mg kg-1, <0.01-0.53 mg kg-1으로 산출되었다 . 위해성 평가는 일일식이섭취허용량 (ADI)으로 평가하였으며 , 퀴노아는 설정된 잔류허용기준인 3.0 mg kg-1, 팥은 최고잔류량을 이용하여 산출하였다 . %ADI 13.2%로 %ADI 80%를 초과하지 않아 위해도는 낮을 것으로 사료된다 . 본 연구는 퀴노아와 팥의 잔류특성을 구명하여 유사 작물 간의 작물 잔류성을 예측할 수 있는 기초자료로 사용될 수 있을것으로 기대된다 .

This study was conducted to evaluate the residual characteristics and safety assessment of fungicide dimethomorph in quinoa and red beans under open field conditions. The test compound dimethomorph was sprayed three times with 7 days intervals to both crops. Quinoa samples were harvested at 30, 21, 14, and 7 days after treatment, while red beans were harvested at 29, 21, 14, 6 and 0 days after treatment. The residues of dimethomorph were extracted by QuEChERs method and analyzed with LC-MS/MS.
The recovery of dimethomorph at fortification levels of 0.1 and 0.5 mg kg-1 were ranged from 89.1 to 109.0% with a relative standard deviation <10%. The method limit of quantification was 0.01 mg kg-1. The residues of dimethomorph in quinoa and red beans found to be <0.01 to 3.64 mg kg-1 and <0.01 to 0.53 mg kg-1, respectively. The acceptable daily intake (ADI) of dimethomorph was used to calculate the safety assessment and it was calculated using the established MRL of 3.0 mg kg-1 for quinoa and the maximum residual amount in red beans. Then the result indicated that the sum of %ADI was 13.2% in both crops. It is considered that the risk is relatively low when the sum of %ADI does not exceed 80%. The result of this study is expected to be used as basic data for evaluating the residual characteristics and safety of pesticides in similar crops.
