Determination of the fungicide vinclozolin in honey and bee larvae by solid-phase and solvent extraction with gas chromatography and electron-capture and mass spectrometric detection.
Methods for the determination of residual vinclozolin in honey and bee larvae are proposed. The fungicide can be extracted with an n-hexane-acetone (70:30, v/v) mixture, or by passage through ODS cartridges which requires no subsequent clean-up. Vinclozolin is quantified by capillary gas chromatography with electron-capture and mass spectrometric detection. Recoveries from spiked samples exceed 90%, with a relative standard deviation of 3.5-4.5%.
