Summary
The efficiency of the extraction methods with acetone and with ethyl acetate are compared with regard to the multi-pesticide residue determination in fruits and vegetables. The ethyl acetate-method gave higher recoveries for polar pesticides and seems somewhat easier, quicker and cheaper in handling but some co-extractives in the GC-extract are observed. In general, both methods gave acceptable and equivalent recoveries for the pesticides tested.
