  • Title: Determination of oxadiargyl residues in environmental samples and rice samples.
    Author: Shi C, Gui W, Chen J, Zhu G.
    Journal: Bull Environ Contam Toxicol; 2010 Feb; 84(2):236-9. PubMed ID: 19784803.
    Abstract:
    Oxadiargyl is a commonly used herbicide in China. We developed a simple, fast, and high-throughput method employing gas chromatography with electron capture detector to determine oxadiargyl residues in food samples (rice, straws) and environmental samples (soil, water). Samples were prepared by a modified QuEChERS procedure. In this method, acetonitrile was used as the extracting solvent. The purifying step was omitted when the chromatographic conditions were optimized. Recoveries ranged from 82.9 to 112.0% for oxadiargyl in all samples, with relative standard deviation values lower than 6.2% at 0.01 mg/kg fortified concentration level.
