TI  - Fast determination of pyrethroid pesticides in tobacco by GC-MS-SIM coupled with 
      modified QuEChERS sample preparation procedure.
PG  - 649-53
AB  - An analytical method was developed for the extraction and determination of 
      pyrethroid pesticide residues in tobacco. The modified QuEChERS (Quick, Easy, 
      Cheap, Effective, Rugged and Safe) method was applied for preparing samples. In 
      this study, methyl cyanide (MeCN)-saturated salt aqueous was used as the 
      two-phase extraction solvent for the first time, and a vortex shaker was used for 
      the simultaneous shaking and concentration of the analytes. The effects of 
      experimental parameters on extraction and clean-up efficiency were investigated 
      and optimized. The analytes were determined by gas chromatography-mass 
      spectrometry-selected ion monitoring (GC-MS-SIM). The obtained recoveries of the 
      analytes at three different fortification levels were 76.85-114.1% and relative 
      standard deviations (RSDs) were lower than 15.7%. The limits of quantification 
      (LOQs) were from 1.28 to 26.6 mug kg(-1). This method was also applied to the 
      analysis of actual commercial tobacco products and the analytical results were 
      satisfactory.
