      chromatography-ion trap-triple stage mass spectrometry.

AB  - A multi-residue method using pressurized liquid extraction (PLE) and liquid 
      chromatography-quadrupole ion trap-triple stage mass spectrometry (LC-IT-MS(3)) 
      has been developed for determining trace levels of pesticides in fruits. The 
      selected pesticides can be distinguished in: benzimidazoles and azoles, 
      organophosphorus, carbamates, neonicotinoids, and acaricides. PLE has been 
      optimized to extract these pesticide residues from oranges and peaches by 
      studying the effect of experimental variables on PLE efficiency. Samples were 
      extracted at high temperature and pressure (75 degrees C and 1500psi) using ethyl 
      acetate as extraction solvent and acidic alumina as drying agent. The recoveries 
      obtained by PLE ranged from 58% to 97% and the relative standard deviation (RSDs) 
      from 5% to 19%. The limits of quantification (LOQs) of the compounds were from 
      0.025 to 0.25mgkg(-1), which are well-below the maximum residue limits (MRLs) 
      established by the European Union (EU) and the Spanish legislations.
