TI  - Simultaneous determination of aminopyralid, clopyralid, and picloram residues in 
      vegetables and fruits using ultra-performance liquid chromatography/tandem mass 
      spectrometry.
PG  - 554-9
AB  - A sensitive and effective method for the simultaneous quantitative determination 
      of aminopyralid, clopyralid, and picloram in vegetables (eggplant, cucumber, and 
      tomato) and fruits (apple and grape) was developed and validated using 
      ultra-performance LC coupled with MS/MS. The three herbicides were successfully 
      separated and independently confirmed in a single run. Different extraction and 
      cleanup methods were used to optimize the pretreatment processes of the residue 
      analysis method. The final method is straightforward and involves extraction with 
      1% formic acid-acetonitrile, and no complicated cleanup process is needed. 
      Determination of the compounds was achieved within 3.0 min. Respective average 
      recoveries using this method at four concentration levels (0.05, 0.1, 0.5, and 
      1.0 mg/kg) ranged from 66.5 to 109.4%, with RSDs in the range of 1.1-19.7% (n = 
      5) for all analytes. The LODs were below 0.010 mg/kg, and the LOQs did not exceed 
      0.036 mg/kg, which were lower than the maximum residue limits (MRLs) of 0.5-5.0 
      mg/kg clopyralid in vegetables and fruits samples, as established by the European 
      Union. This study provides a theoretical basis for China to develop MRLs and an 
      analytical method for aminopyralid, clopyralid, and picloram in vegetables and 
      fruits.
