摘要：

A multiresidue method that enables determination of many pesticides in agricultural products by GC-ECD was studied. First, 63 pesticides were selected as agrochemicals commonly used in crop protection in this country, and/or found in agricultural products over the past 6 years (April 1996-March 2002) in Aichi Prefecture. A sample was extracted with acetonitrile and the acetonitrile layer was separated by salting-out. The extract was purified on a GPC system with a graphitized carbon columns, and then by a Florisil mini-column fractionation. The test solution was subjected to one-injection, dual-column GC with dual ECD (column: Stx-CLPesticides and Stx-CLPesticides2). The detection limits of the pesticides were in a suitable range (0.0001-0.01mug/ g) for monitoring pesticide residues in agricultural products. The method was applied to 203 commercial agricultural products to demonstrate its suitability for routine analysis.
