文摘

An analytical procedure using accelerated solvent extraction and capillary gas chromatography withelectron capture and flame photometric detections was developed to simultaneously determineresidues of different pesticides in fruits and vegetables. Single laboratory validation of the methodwas carried out for 28 compounds selected from eight pesticide classes, in blank and fortified samplesof fresh pear, cantaloupe, white potato, and cabbage. The method had to meet specific establishedvalidation criteria for regulatory purposes applicable to our laboratory. At each of the two fortificationlevels studied, 24 of the 28 pesticides gave recoveries of more than 70% with a coefficient of variationof less than 10%. With respect to existing procedures, the method showed acceptable limits ofdetection (from 0.0019 to 0.14 r.gif">g/g depending on the pesticide and matrix) while minimizingenvironmental concerns, time, and labor.Keywords: Analysis; accelerated solvent extraction; gas chromatography; fresh produce; pesticide;validation
