본 연구에서는 광주광역시 학교급식 농산물의 잔류농약을 모니터링하고 섭취량에 따른 위해평가를 실시하였다. 2015년부터 2017년 까지 광주광역시 소재 학교에 공급되는 농산물 320건을 실험대상으로 하였다. 농산물 전처리 및 잔류농약 분석은 식품공전 다종 농약 다성분 분석 제2법에 따라 120종의 잔류농약을 실험하였다. 검량선에 대한 직선성 상관계수는 0.9923~1.0000, LOD는 0.004~0.019 mg/kg, LOQ는 0.012~0.057 mg/kg으로 양호하게 나타났으며 회수율은 79.1~100.2%로 나타났다. 학교급식에 사용되는 농산물 320건 중 18건(5.6%)에서 잔류농약이 검출되었으며, 고구마 순 1건(0.3%)이 잔류농약허용기준을 초과하였다. 잔 류농약 검출빈도는 고추 8회, 파프리카 3회로 다른 농산물에 비해 높은 검출빈도를 나타내었고 가장 높은 검출빈도를 나타낸 잔류농약은 boscalid(4회)와 acetamiprid(3회)로 나타났다. 실험결과 학교급식 농산물 중 고추, 파프리카, 고구마 순에 대한 잔류농약 관리가 필요한 것으로 나타났다. 잔류농약 위해도 평가 결과 고구마 순에서 검출된 bifenthrin이 64.18%로 가장 높았으며, 고추에서 검출된 boscalid 등의 Hazard index는 0.03~8.23%로 나타나 학교 급식 농산물의 Hazard index는 안전한 수준으로 평가되었다. 그러나 채소류를 학교급식 식재료로 제공할 경우 잔류농약 식이섭취량을 최소화하기 위해 철저한 세척이 필요한 것으로 판단되며 친환경 농산물의 식재료 보급 확대가 필요한 것으로 판단된다.
This study was performed to monitor the residual pesticides in agricultural products used in school foodservice in the Gwangju metropolitan area. Risk assessment was also carried out based on the amount of agricultural products consumed. A total of 320 agricultural products supplied to schools in Gwangju were analyzed from 2015 to 2017. The pre-treatment and residual pesticide analysis of these products was conducted in accordance with the second method for multi-residue analysis of pesticides in the Korean food code. The hazard index was calculated by dividing the estimated daily intake (EDI) of pesticides by the acceptable daily intake (ADI). The linearity correlation coefficient for the calibration curve was 0.9923 to 1.0000, LOD 0.004 to 0.019 mg/kg, LOQ 0.012 to 0.057 mg/ kg, and recovery was 79.1 to 100.2%. Residual pesticides were detected in 18 (5.6%) of 320 agricultural products used for school foodservice, and one sample of sweet potato stem (0.3%) exceeded the maximum residual limit (MRL). The detection frequency for chili peppers and bell peppers was higher than that for other agricultural products. The frequently-detected pesticides were boscalid and acetamiprid. These results showed that residual pesticide management is needed for chili pepper, bell pepper and sweet potato stem among agricultural products supplied to schools. The hazard index of bifenthrin in sweet potato stem showed the highest (64.18%), and the other pesticides were 0.03- 8.23%. These results indicated that agricultural products supplied to schools in Gwangju were safe for consumption. To minimize the intake of residual pesticides, it is necessary to not only thoroughly wash agricultural products but to also ensure the expanded supply of products that are pesticide-free.
