Multiresidue method for the gas chromatographic determination of pesticides in honey after solid-phase extraction cleanup

A new multiresidue method is described for the determination of pesticides in honey. The method involves dissolution of the honey in a methanol-water mixture, followed by solid-phase extraction cleanup and gas chromatographic determination. Twenty-six pesticides used on flowering field crops, on flo wering fruit and vegetables, or as acaricides to control Varroa jacobsoni i n beehives are determined by the method. Recoveries from honey, spiked at 0 .02-1.6 mg/kg, ranged from 85 to 127% with a relative standard deviation (R SD) of 2-16%, except for the RSD of 27% for captan at 0.05 mg/kg.
