  • Title: Determination of multi-pesticide residues in cereals, cereal products and animal feed using gel-permeation chromatography.
    Author: Chamberlain SJ.
    Journal: Analyst; 1990 Sep; 115(9):1161-5. PubMed ID: 2091486.
    Abstract:
    Residues of organophosphorus, organochlorine and synthetic pyrethroid pesticides and insect growth regulators were determined in cereals and cereal products. Samples were extracted with acetone-methanol and the extracts cleaned-up by gel-permeation chromatography. The mean recoveries were: 99%, organophosphorus; 94%, organochlorine; 99%, synthetic pyrethroid; and 99%, insect growth regulators.
