摘要：

A comparative study of different multiresidue methods for the determination of organochlorine and organophosphorus pesticides in fruit samples has been carried out. Recoveries for each pesticide added to a peach sample were obtained after applying different extraction systems. The study was performed with the following pesticides: dimethoate, chlorpyrifos, fenitrothion, lindane, malathion, methidathion, phentoate and tetradifon. Extraction systems induded: acetonitrile+anhydrous sodium sulphate, acetonitrile-water+Celite acetone and acetone-methanol. Determination of pesticides was performed by gas capillary chromatography with ECD and NPD. GC/FPD and GC/MS were also used for confirmation and identification purposes. © 1990 Friedr.
