  • Title: Microprocedure for determination of carbaryl in blood and tissues.
    Author: Mount ME, Oehme FW.
    Journal: J Anal Toxicol; 1980; 4(6):286-92. PubMed ID: 6782371.
    Abstract:
    A microprocedure was adapted for the extraction and cleanup of carbaryl from blood and tissues of animals poisoned with this insecticide. Ball-mill extraction using acetone and methylene chloride, removal of lipid material by a freeze-out procedure, and florisil microcolumn cleanup were employed. Derivatization of carbaryl with heptafluorobutyric anhydride in the presence of trimethylamine allowed rapid processing for gas-liquid chromatographic separation on 3% OV-17 and electron-capture detection. Limits of carbaryl detection were 0.02 ppm for blood and 0.1 ppm for tissue. This procedure allowed simultaneous processing and sensitive detection of carbaryl in numerous small samples.
