Analysis of Insecticide Residue and Digestion Dynamics of Spinetoram in Banana Fruits, Petals and Soil
摘要
Abstract
In order to evaluate the safety of spinetoram on banana, the residue and degradation dynamics of spinetoram in banana were detected by ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The results showed that the limits of detection (LOD) of spinetoram in banana fruit, petal and soil were both 5 μg/kg. And the limits of quantification ( LOQ) were both validated calculated as 17 μg/kg. At the spiked levels of 0.01-0.20 mg/kg, the average recoveries of acetochlor in fruit, petal and soil were 89.6%-95.2%, 76.5%-89.8% and 75.8%-86.5%, and the relative standard deviations was 5.03%-7.10%, 5.16%-7.24% and 2.26%-5.83%, respectively. The half-lives of acetochlor in fruit, petal and soil was 5.6 d, 4.5 d and 6.5 d. Taken together, the findings reveal that spinetoram belongs to the easily degradable pesticide type. The present study suggests that UPLC-MS / MS could be applied to detect and analyze spinetoram residues and digestion dynamics in banana.关键词
