        농산물 중 Bifenazate의 분석법 개선 및 모니터링

        박은희(Eun-Heui Park),고명진(Myoung-Jin Go),조명식(Myong Shik Cho),김영선(Young-Sun Kim),이진하(Jin-Ha Lee) 한국농약과학회 2010 농약과학회지 Vol.14 No.1

        The analytical method for bifenazate was developed using a HPLC (UVD). Also, analytical condition of LC/MS was set up for bifenazate. We validated the method for the precision and the reproducibility. The correlation coefficient of bifenazate ranged from 0.05 to 2.5 ㎎/㎏ was 1.0. Limit of quantitation (LOQ) was 0.01 ㎎/㎏. To measure recoveries from agricultural products such as foxtail millet (cereal grains), kidney bean (beans), orange (fruits), perilla leaves (vegetables) and oak mushroom (mushrooms), bifenazate was spiked. Mean recoveries of bifenazate for each sample were 82.7~104.1% at the level of 0.1 ㎎/㎏ and 73.1~104.3% at the level of 0.5 ㎎/㎏. The relative standard deviations (n=3) were 0.2∼9.7%. Pesticide residues for bifenazate were investigated in 16 commodities (rice, foxtail millet, buckwheat, kidney bean, peanut, sesame, orange, grapefruit, kiwifruit, spinach, perilla leaves, leek, garlic stem, garlic, ginger and oak mushroom) collected from 22 provinces in 2009. Bifenazate was analyzed using analytical method by HPLC from 304 samples, and residue was not detected.
