Abstract
A simple and rapid method has been developed for the simultaneous
determination of five pyrethroid pesticides in vegetables. Residues were extracted
with acetone and methylene chloride. Extracts were cleaned up by solid-phase
extraction mixed-mode column using quaternary amine and aminopropyl
sorbents. The pesticides were determined by gas chromatography with electron
capture detector. The recoveries from three vegetables: carrot, cucumber and
green mustard, spiked at 0.25-0.5 mg/kg were 72.0 to 117.0%. The results were
comparable to those obtained by the silica gel cleanup method.
