Abstract
The purpose of this study was to investigate 253 kinds of pesticide residues in 58 commercial dried agricultural products in Seoul. The determinations of the pesticide residues were performed using multiresidue methods and were carried out by a gas chromatography-nitrogen phosphorus detector (GC-NPD), an electron capture detector ($GC-{\mu}ECD$), a mass spectrometry detector (GC-MSD) and high performance liquid chromatography-ultraviolet detector (HPLC-UV), and a fluorescence detector (HPLC-FLD). The pesticide residue detection rate in the commercial dried agricultural products was 24.1% (14 of 58 samples). Twelve pesticide residues without maximum residue limits (MRLs) were detected. In the vegetable groups, the frequency of pesticide residues was found to be in the increasing order of dried fruiting vegetables > dried leafy vegetables > dried stalk and stem vegetables. The pesticides used on dried red pepper in the dried fruiting vegetables were varied (7 kinds) and numerous (4 of 8 samples). The pesticide types detected in the commercial dried agricultural products were in the order of pyrethroid > organochloride > organophosphorus and insecticide > fungicide > herbicide ${\cdot}$ nematicide. The primary pyrethroid pesticide detected was cypermethrin. According to the producing areas of products, large numbers of pesticide residues were found in the order of Korea, China, North Korea, USA, and Vietnam.
서울지역에 유통되고 있는 국내산 및 수입산 건조농산물 58건을 대상으로 다성분 동시분석방법에 따라 GC-NPD, $GC-{\mu}ECD$, HPLC-UV와 HPLC-FLD로 분석가능한 총 253종의 농약잔류량을 분석한 후 GC-MSD로 확인한 결과 총 14건의 건조농산물에서 잔류농약이 검출되어 24.1%의 검출률을 나타내었고, 이 중 건조 채소류의 검출률은 25.5%였다. 품목별 잔류농약의 검출률은 건조과채류, 건조엽채류, 건조엽경채류 순으로 높았으며, 특히 건조 과채류 중 건조고추의 잔류농약 분포가 다양하고 검출빈도가 상당히 높았다. 건조 농산물의 기준에 없는 12종의 잔류농약이 검출되었으며, 합성피레스로이드계, 유기염소계, 유기인계 순으로 검출빈도가 높았고, 특히 합성피레스로이드계 중 cypermethrin의 검출 횟수가 가장 많았다. 또한 대상목적에 따라 분류하면, 살충제, 살균제, 제초제, 살선충제 순서로 검출건수가 많았다. 산지별로 보면, 국내산, 중국산 ,북한산, 미국산, 베트남산의 순서로 잔류농약의 검출건수가 많았으며, 국내산은 과채류에서 수입산은 엽경채류에서 잔류농약의 검출빈도가 높았다.
