摘要：

A multiresidue screening method for pesticides in plant materials is presented. Aliquots (10 g) of samples are extracted with acetone-water, the extract is concentrated by reversed-phase solid-phase extraction and cleaned up on Florisil. The pesticides are analyzed by gas chromatography in combination with electron-capture detection or mass spectrometry in the negative chemical ionization mode. The method has been tested for 23 pesticides in 19 different plant materials at a level of 0.02-3 ppm. The advantages of mass spectrometric detection with negative chemical ionization for the determination of pesticides are discussed.
