경남지역에서 생산되는 채소류 내 잔류농약에 대한 다성분 동시분석법 유효성 검증 및 모니터링

Abstract

The purpose of this study was to monitor the safety management of residual pesticides in vegetables that can be eaten raw. To evaluate the safety of agricultural products produced in Gyeongsangnam-do, including Busan, 463 residual pesticides were analyzed, and the risk was assessed in 898 cases of lettuce, chili pepper, perilla leaf, and chives. This study investigated four items of lettuce, perilla leaves, peppers, and chives consumed mainly in reproduction using the QuECHERS (quick, easy, chef, effective, mugged, and safe) pretreatment method. From 2020 to 2021, a total of 897 cases subject to the application of Procymidone and Dinotefuran specifications specified in the Food Code were investigated using LC-MS/MS and GC-MS/MS methods, and significant differences between the groups were confirmed. Recently, in 2020, several nonconformities occurred in the order of chives, green onions, lettuce, cabbage, chives, spinach, crown daisy, and jujube, followed by dinotefuran, carbofuran, diazinon, procymidone, tebuconazole, ethoprophos, flubendiamide. In 2021, in the order of lettuce, chives, chwinamul, spinach, green onions, perilla leaves, crown daisy, celery, cabbage, and rice, occurred in the order of nonconformity. By ingredient, diazinon, dinotefuran, procymidone, carbonofuran, carbendazim, linuron, imicyafos, and fluopyram were common. Therefore, in this research, four items that can be reproduced were selected and analyzed among items with a high frequency of dissent. In the analysis results, monitoring was performed on procymidone and dinotefuran, which were recently detected frequently. Products produced and collected in the Gyeongnam region from January to June 2022 were seen below the standard. The recovery rate test (898 samples) to confirm accuracy showed that grape juice was 70-120%. The procymidone and dinotefuran calibration lines showed excellent linearity with a correlation coefficient of 0.9998 and 0.9869. As a result, there were no pesticide components exceeded the standard value, but trace amounts were detected in some items. As such, agricultural products can be safely eaten through education on the safety of pesticide use by government agencies and proper cleaning methods by consumers.
