Residue dynamics of acetamiprid in watermelon and soil was studied in this paper utilizing liquid chromatography with tandem mass spectrometry (LC-MS/MS). The LODs for acetamiprid in whole watermelon, melon flesh and soil were 0.002 mg/kg. The fortified recoveries ranged from 73.7% to 107.5% with relative standard deviations (RSDs) of 1.7%-5.9%. Acetamiprid dissipated in watermelon and soil with the half-life 3.12-3.92 days and 1.18-1.46 days in two locations Beijing and Shandong provinces, respectively. In the terminal residue experiment, no higher residue than 0.01 mg/kg in melon flesh and 0.3 mg/kg in whole watermelon and soil were detected.
本研究采用液相色谱-串联质谱法（LC-MS/MS）研究了吡虫啉在西瓜和土壤中的残留动态。吡虫啉在整个西瓜、瓜肉和土壤中的检测限（LODs）为 0.002mg/kg。加标回收率在 73.7%至 107.5%之间，相对标准偏差（RSDs）为 1.7%-5.9%。吡虫啉在西瓜和土壤中的消解半衰期分别为 3.12-3.92 天和 1.18-1.46 天，在北京和山东两个地点。在最终残留试验中，未检测到瓜肉中吡虫啉残留量高于 0.01mg/kg，以及整个西瓜和土壤中吡虫啉残留量高于 0.3mg/kg。
