摘要：

A SPME-GCMS method for the determination of a mixture of organophosphorus pesticides (phorate, diazinon, methylparathion, fenitrothion, malathion, fenthion, ethyl-parathion and methidathion) in wine and different fruit juices was developed. The procedure is solvent-free, simple (direct SPME without further sample pre-treatment) and highly sensitive. Estimated LOD and LOQ ranged from 2 to 33 ng/ml and from 7 to 109 ng/ml, respectively, in wine, and from 2 to 90 ng/ml and from 7 to 297 ng/ml, respectively, in fruit juices. LOQ achieved by the present method are almost always below the maximum residue levels recommended by the European legislation. (C) 2003 Elsevier Ltd. All rights reserved.
