Abstract
This experiment was carried out to analyze for pesticide residues in 17 different types of the special of geographical indication. We purchased 3 cereal grains, nuts and seeds, 3 fruits, 8 vegetables, mushrooms and other plants (Korean medicines) mainly at the agricultural cooperative's joints markets. Total 209 pesticides including multi-analysed pesticides (204) and single-analysed pesticides (5 ; acephate, methamidophos, monocrotophos, omethoate, vamidothion) were analysed with a GC/MS/MS, an HPLC/UVD (PDA) and a GC/FPD. No. 83 method and single-analysed method (Screening of multi-pesticide residue in the special products of geographical indication) of Korea Food Code was selected for validation in recovery and interferences of matrice. The results were as follows: among the selected 17 the special products, the residual pesticides were detected in 8 types of the special products (40 in 302 samples, detection ratio; 13.2%). All of the samples were not detected over MRLs, but tebuconazole, procymidone and isoprothioran were detected with considerable high frequency. These results could be used as KFDA official methods for the analysis of pesticide residues in foods and reference data will be provided to the related institutions.
본 연구는 국내의 지리적표시제 등록특산물을 대상으로 농약 잔류실태를 조사하여 식품안전 정책수립의 기초자료와 잔류농약에 대한 식품의 안전성을 평가하고자, 지리적 표시 등록 특산물 17품목(마늘 1, 마늘 2, 마늘 3, 마늘 4,고추, 양파 1, 양파 2, 쌀 1, 쌀 2, 쌀 3, 참외, 사과, 밤, 대추, 황기, 표고버섯, 구기자)을 선정하여 잔류 실태를 조사하였다. 조사대상 농약으로는 다성분 분석농약 204종과 단성분 분석농약 5종(acephate, methamidophos, monocrotophos, omethoate, vamidothion)을 포함한 209종의 농약에 대해 잔류량을 조사하였으며, 분석장비로는 GC/MSMS, HPLC/UVD(PDA)와 GC/FPD를 사용하였다. 분석법방법으로는 식품공전의 83번 다성분분석법과 단성분분석법을 사용하였다. 분석결과 특산물 17품목 중 8품목(고추, 양파 1, 쌀 2, 쌀 3, 참외, 사과, 대추, 구기자)에서 잔류농약이 검출되었고, 검출시료수는 302건중 40건으로 13.2%의 잔류농약 검출율을 보였다. 그러나 모두 식품의 농약잔류허용기준 미만이었다.
