Summary

A simple and efficient method is described for the determination of fenpropathrin in oranges, pears, apples and strawberries. The procedure is based on the extraction of each homogenized fruit sample with hexane:acetone (1∶1, v/v) mixture, followed by a cleanup technique on a column packed with florisil, using a hexane:ethyl ether (7∶3, v/v) mixture, and gas chromatographic analysis with electron capture detection (ECD). The fortification levels (0.5;1.0;2.0 mg kg−1) were selected according to the maximum residue limits (MRLs) established for fenpropathrin by Brazilian legislation. Mean recoveries from five replicates of fortified fruit samples ranged from 83 % to 98%, with coefficients of variation from 1.4 to 13.5 and detection limits varying from 0.1 to 0.2 mg kg−1.
