Abstract

The monitoring of the uniconazole residual pesticide for agricultural products was conducted by multiclass pesticide multiresidue methods. Samples were collected from June to November, 2011. Uniconazole pesticide was detected in 49 samples from a total of 3,939 samples. The amount of uniconazole pesticide ranged from 0.09 to 17.89 mg/kg in 49 samples. This method was described for the simultaneous determination of uniconazole by gas chromatography with a nitrogen phosphorus detector (GC-NPD) and mass spectrometry (MS). The limit of detection and quantification were 0.006 and 0.018 mg/kg GC-NPD, respectively. For an evaluation of the GC-NPD method, uniconazole spiked into gyeojachae at a level of 0.5, 5 mg/kg was determined. The recoveries of uniconazole by the GC-NPD method ranged from 83.4 to 101.4%. The results indicate that the method of simultaneous analysis is applicable to uniconazole analysis.

2011년 6월부터 11월까지 농산물 중 GC-NPD 및 GC-MSD를 이용한 동시 다성분 분석법을 이용하여 uniconazole의 잔류실태 조사를 실시하였다. 2011년 6월부터 11월까지 서울지역에 유통되고 있는 농산물 121종 총 3,939건에 대하여 잔류실태조사를 실시한 결과 49건에서 uniconazole이 검출되었다. 품목별로는 겨자채가 69.4%로 가장 많이 검출되었다. Uniconazole의 검출양은 0.09 mg/kg에서 17.89 mg/kg로 나타났다. 본 연구에서는 uniconazole에 대하여 GC-NPD 및 GC-MSD를 이용한 동시분석법의 가능성을 검토하였다. GC-NPD의 검출한계와 정량한계는 각각 0.006 mg/kg와 0.018 mg/kg이었다. 겨자채에 표준용액을 0.5, 5 mg/kg 농도로 하여 회수율을 측정한 결과 83.4%에서 101.4%까지 양호한 결과를 나타내었다. 본 연구를 통하여 동시분석법으로 보다 효율적인 검사가 가능할 것으로 기대된다.
