AB  - A rapid, sensitive and reliable analytical method for thidiazuron residues in 
      apple and soil was established. The residual levels of the pesticide in apple and 
      soil were determined by high performance liquid chromatography (HPLC) with UV 
      detector. Samples of apple and soil were extracted with acetonitrile-water 
      solutions, and then cleaned up by Florisil or C(18) cartridges. The results 
      showed good linearity (r(2)=1.000) over the concentration range of 0.01-5.0 mg/L. 
      Limits of quantification (LOQ) of the method were 0.01 mg/kg for both soil and 
      apple. Recovery from the apple and soil samples were 83.36%-84.08% and 
      85.27%-89.83%, respectively, and the corresponding relative standard deviations 
      (RSDs) of the recovery data were 0.155%-0.524% and 0.475%-4.79% for the three 
      fortified levels (0.01, 0.1, 0.5 mg/kg). The analyte in the samples were further 
      confirmed by electrospray ionization tandem mass spectrometry (ESI-MS/MS). It was 
      demonstrated that the proposed method was simple and efficient, and particularly 
      suitable for detecting thidiazuron residues in apple and soil.
