AB  - A simple and sensitive multiresidue pesticide analysis method was developed and 
      validated for 213 pesticides in leek and garlic based on QuEChERS (quick, easy, 
      cheap, effective, rugged, and safe) procedure combined with gas 
      chromatography-triple quadrupole mass spectrometry. In the QuEChERS method, 
      commercial extraction salt packet, dispersive solid-phase extraction adsorbent 
      packet, and ceramic homogenizer were used to simplify the extraction procedure. 
      The gas chromatography-tandem mass spectrometry (GC-MS/MS) parameters were 
      optimized for analysis of 213 pesticides within a 38-min run time with a limit of 
      quantification for most of the pesticides at 2 mug kg(-1). The coefficient of 
      determination (r(2)) was >0.99 within the calibration linearity range of 2-400 mug 
      kg(-1). Most recoveries at 2, 5, 10, 20, 50, 100, and 200 mug kg(-1) were in the 
      range of 70-120% (n = 6) with associated relative standard deviations (RSDs) of 
      <20%, indicating satisfactory precision. Real leek and garlic samples were 
      analyzed for method application.
