Abstract

This work was conducted to apply the multi class pesticide multiresidue method for determining the use of hexaconazole in the agricultural products using GC-NPD. The multi class pesticide multiresidue method results were validated for the assay of hexaconazole by using linearity, accuracy, precision, limit of detection and quantitation. The linearity in the concentration ranged from 0.025 to 5.0 mg/L ($R^2$ > 0.999). Lettuce recoveries ranged from 89.42% to 94.15% with relative standard deviations below 7.78%, for spiking levels from 0.04 to 4.0 mg/kg. The limit of detection was 0.04 mg/kg, and the limit of quantitation was 0.11 mg/kg. The intra- and inter-day precisions were 2.42~3.49% and 4.90~7.78%, respectively. We suggested that the multi class pesticide multiresidue method for determining hexaconazole was highly accurate and reproducible, and it will be used as a routine analysis in agricultural products.

농산물 중 hexaconazole 분석을 위해, GC-NPD를 이용하여 다종농약 다성분 분석법을 적용하고자 본 연구를 수행하였다. Hexaconazole의 다종농약 다성분 분석법 유효성 검증은 직선성, 정확성, 정밀성, 검출한계 및 정량한계로 하였다. 0.025~5.0 mg/L의 농도에서 검량선의 상관계수($R^2$)는 0.999이상의 우수한 직선성을 보였다. 상추에 0.04~4.0 mg/kg을 첨가한 농약의 회수율은 89.42~94.15%였고, RSD는 7.78%이하의 재현성을 나타냈다. 검출한계는 0.04 mg/kg였고, 정량한계는 0.11 mg/kg였다. 일간 및 일내 정밀도는 각각 2.42~3.49%와 4.90~7.78%였다. 본 연구결과에서 다종농약 다성분 분석법을 이용한 hexaconazole 분석은 매우 정확하고, 높은 재현성을 보여, 농산물 중 hexaconazole 분석에 적용할 수 있을 것으로 판단된다.
