Establishment of Standard Analytical Methods for Determination of Pesticide Residuse in Crops -Tests of Terbufos, Diflubenzuron, Aldicarb and Oxamyl

本研究發展出了利用氣相層析（gas chromatography, GC）及高效液相層析（high performance liquid chromatography, HPLC）檢驗作物中托福松（terbufos）、二福隆（diflubenzuron）、得滅克（aldicarb）及歐殺滅（Oxamyl）殘留之檢驗方法。托福松以丙酮自作物中萃取出，再經淨化後以氣相層析儀分析之，結果添加0.05～0.15ppm檢體濃度之平均回收率為82.1～98.2%，最低檢出量為12.5ppb。二福隆、得滅克及歐殺滅以丙酮自作物中萃取出，再經不同淨化程序後分別以高效液相層析儀分析之，結果添加0.05～4.5ppm檢體濃度之平均回收率為82.6～98.5%。最低檢出量分別為0.05、0.05及0.08ppm。"

Methods using gas chromatography (GC) and high performance liquid chromatography (HPLC) to determine terbufos, diflubenzuron, aldicarb, and oxamyl in crops have been developed. Terbufos was extracted from crops with acetone, and determined by GC after purification. Recovery studies were performed at 0.05 ～0.15ppm fortification levels and recoveries of terbufos were between 82.1 and 98.2%. The limits of detection of terbufos in crops tested were 12.5 ppb. Diflubenzuron, aldicarb and oxamyl were extracted from crops with acetone, cleaned up, and determined by HPLC individually. Recovery studies were performed at 0.05～4.5ppm fortification levels. Recoveries were between 82.6 and 98.5%. The limits of detection of diflubenzuron, aldicarb and oxamyl in crops tested were 0.05, 0.05 and 0.08ppm, respectively.
