Dissipation and Evaluation of Metaldehyde Residues in Cabbage Grown in Open Fields

Abstract:

Article Preview

The residual levels and dissipation rates of metaldehyde in cabbage and soil at three main cabbage-growing areas in china were determined by A simple,rapid and sensitive analytical method with liquid chromatography with TripleQuad mass spectrometry (LC–MS–MS). The limit of quantification (LOQ) was 0.0005,0.0005mg/kg for soil and cabbage, respectively. The mean half-life of metaldehyde was 5.84 days in cabbage and 3.17 days in soil. The final residues in cabbage and soil detected at 7 days after the last spreading were considerably all below 1mg/kg (the MRL of China). Low residues in cabbage and soil suggest that this pesticide may be safe to use under the recommended dosage.
