Abstract/OtherAbstract:
A rapid and simple multiresidue method has been established for determination of pesticide residues in processed foods by GC/MS/MS. The pesticides were extracted with ethyl acetate, and were cleaned up with a double-layered SPE cartridge column (graphite carbon black/PSA silica gel). Recovery tests of 258 pesticides from five kinds of processed foods (dumpling, curry, French fries, fried chicken, fried fish) were performed at two different fortification levels of 0.02 and 0.1 microg/g, and 184 pesticides showed acceptable recovery (70-120%) with relative standard deviation of <or=20% at both concentrations. The high selectivity of GC/MS/MS gives a very clean chromatogram, making compound identification and confirmation easy. This method could be applied to the determination of pesticide residues in processed foods.
