Abstract: A method was developed for the simultaneous determination of fipronil, fipronil desulfinyl, fipronil sulfone and fipronil thioether in leek and soil. The residues were extracted from samples with acetonitrile. Soil sample was cleaned up by 100 mg florisil, and leek sample was cleaned up by solid phase extraction (SPE) column. They were detected by ultrahigh performance liquid chromatography-mass spectrometry (UPLC-MS/MS) under multiple reaction monitoring mode, external standard method for quantitative by matrix-match standard solution. Average recoveries of the method ranged from 71.8%-107.9%, and the relative standard deviation was 1.5%-15.4%. The limit of detection (LOD) of these four compound were in the range of 0.0001-0.012 ng, while limit of quantification (LOQ) was 0.001 mg·kg-1 in soil and 0.002 mg·kg-1 in leek, respectively. The method was simple and reliable. It meets with the requirement of pesticide residues analysis, and could be applied for determining fipronil, fipronil desulfinyl, fipronil sulfone and fipronil thioether in leek and soil samples. -
