본 연구에서는 서울 북부지역에서 유통된 1,737건의 농 산물을 대상으로 잔류농약 실태 조사 및 위해성 평가를 하였다. 분석 시료는 QuEChERS 법으로 전처리한 후 GCMS/ MS 및 LC-MS/MS를 이용하여 분석하였으며, 다빈도 부적합 성분을 대상으로 직선성과 정량한계, 회수율, 상대 표준편차(RSD%) 구한 결과 OECD 및 Codex의 기준에 적 합하였다. 또한 모니터링 결과 72품목 560건(32.2%)에서 잔류농약이 검출되었으며 22품목 38건(2.2%)이 잔류농약 허 용치를 초과하였다. 잔류농약이 많이 검출된 품목은 과일류 53.8%, 채소류 33.0%, 허브류 28.6%, 두류 15.4%, 곡류가 10.5% 순이였으며, 잔류농약 허용치를 초과한 품목은 채소 류 중 엽채류, 엽경채류, 근채류, 향신료 및 버섯 등이었다. 검출된 농약은 105종으로 그 중, dinotefuran, fluxametamide, chlorfenapyr, azoxystrobin, carbendazim이 가장 많이 검출되 었으며, terbufos, carbendazim, fluxametamide 등 23종의 성 분에서 잔류 허용기준이 초과되었다. 잔류허용기준을 초 과한 농약에 대해 위해 평가를 수행한 결과 위해 지수가 0.00003-1.31406%로 매우 낮은 수준으로 산출되어 안전한 것으로 평가되었다.

In this study, we investigated the concentrations of pesticide residues in agricultural products marketed in northern Seoul and assessed their potential health risks. A total of 1,737 samples were collected using the QuEChERS method, followed by LC-MS/MS and GC-MS/MS. Pesticide residues below the MRLs were detected in 560 samples of 72 items (32.2%), but 38 samples of 22 items had pesticide residues above the MRLs. Residual pesticides were detected in 53.8% of fruits, 33.0% of vegetables, 28.6% of herbs, 15.4% of beans, and 10.5% of rice samples. Most of the samples that exceeded the MRLs were vegetables, especially leafy, stalk, stem, and root vegetables; herbs and mushrooms also exceeded the permitted MRLs. Of the 105 pesticides investigated, dinotefuran, fluxametamide, chlorfenapyr, azoxystrobin, and carbendazim were the most frequently detected, whereas 23 pesticide residues, including terbufos, carbendazim, and fluxametamide, were detected above the MRL values. The hazard indices were calculated as 0.00003–1.31406%, which suggests that the investigated pesticide residues in the samples were within safe levels, but continuous monitoring of pesticides in agricultural products is needed to ensure the safety of consumers.
