TI  - Multiresidue method for determination of 90 pesticides in fresh fruits and 
      vegetables using solid-phase extraction and gas chromatography-mass spectrometry.

AB  - A multiresidue method for analysis of 90 pesticides with different 
      physico-chemical properties in fruits and vegetables was developed. The method 
      involves a rapid and small-scale extraction procedure with acetone using vortex 
      mixing. Solid-phase extraction (SPE) on a highly cross-linked polystyrene 
      divinylbenzene column (LiChrolut EN) was used for clean-up and pre-concentration 
      of the pesticides from the water-diluted acetone extracts. For most fruit and 
      vegetable samples this partial clean-up was sufficient, but some of them with 
      more co-extracting substances need further clean-up (cereals, spinach, carrots, 
      etc.). Diethylaminopropyl (DEA) modified silica was used for efficient removal of 
      interferences caused by various organic acids, sugars, etc. The pesticide 
      residues were determined by gas chromatography with a mass selective detector 
      (GC-MS). The majority of pesticide recoveries for various fruits and vegetables 
      were >80% in the concentration range from 0.01 to 0.50 mg/kg, except for the most 
      polar pesticides (methamidophos, acephate, omethoate) which cannot be determined 
      by this method. The limit of quantitation for most of the pesticides was 0.01 
      mg/kg with majority of relative standard deviations (R.S.D.s) below 10%.
