초록

본 연구는 최근 생산단계 참외에서 검출 빈도가 높았던 7성분(chlorfenapyr, dimethomorph, dinotefuran, fluopicolide, fluopyram, propamocarb, thiamethoxam)에 대해 안전사용기준과 안전사용기준 배량으로 살포 후 세척과 껍질제거에 따른 농약 잔류량 변화를 확인하였다. 잔류농약의 분석은 QuEChERS 방법에 준하여 전처리 후 LCMS/MS와GC-MS/MS를 이용하여 정량 분석하였다. Chlorfenapyr 등 7종의 성분에 대한 회수율은 81.6-109.0%의범위를 보였고, C.V. (Coefficient of Variance, %)는 10% 이내로 나타났다. 정량한계는 모두 0.01 mg/kg 이었고, matrix matched 검량선의 직선성은 0.991 이상의 결정계수(r 2 )를 보여 본 연구 수행에 적합한 분석법임을 확인하였다.
세척에 따른 감소율은 dimethomorph 58.0% > propamocarb 31.8% > fluopicolide 31.0% > thiamethoxam 25.6% > chlorfenapyr 22.0% > fluopyram 19.6% > dinotefuran 16.4% 순으로 나타났고, 껍질제거에 따른 감소율은propamocarb 96.6% > dimethomorph 94.5% > fluopicolide 81.5% > dinotefuran 80.5% > thiamethoxam 79.8% > fluopyram 75.9% 순으로 높은 감소율을 보였다.

영어초록

This study was conducted to experiment on decrease residue patterns of 7 pesticides in Korean melon after washing and peeling. The test pesticides diluted by recommended dose and double recommended dose were sprayed one time and then samples were collected at the 1 days (24 hours) after spray days. The pesticides were extracted with QuEChERS method and residues were analyzed by LC-MS/MS and GC-MS/ MS. Method LOQ in 7 pesticides were 0.01 mg/kg (limit detected 0.025 ng) and recoveries of test pesticides in Korean melon found to be 81.6-109.0%. The matrix matched calibration curves for 7 pesticides in Korean melon yielded good linearity (r 2 > 0.991). As results, removal rates after washing; dimethomorph 58.0% > propamocarb 31.8% > fluopicolide 31.0% > thiamethoxam 25.6% > chlorfenapyr 22.0% > fluopyram 19.6% > dinotefuran 16.4%, and after peeling; propamocarb 96.6% > dimethomorph 94.5% > fluopicolide 81.5% > dinotefuran 80.5% > thiamethoxam 79.8% > fluopyram 75.9%, respectively. Based on the results of this study, it may provide a basic safety information for the management of health from pesticide residues in agricultural products.
