title: [Determination of residues of the fungicide benzimidazole carbamic acid methyl ester and its metabolites 2-aminobenzimidazole and benzimidazole].
abstract: The authors describe a method for extracting and determining benzimidazole carbamic acid methyl ester (MBC) in the presence of its metabolites 2-aminobenzimidazole and benzimidazole. The determination is performed thin-layer and paper chromatographically using visual spot comparison. A sensitive biological method is employed for the detection of MBC. The metabolites are assayed by chemical procedures. The smallest amounts of residues that the authors could detect were: 0.01 p.p.m. of MBC and approximately 0.2 p.p.m. of the metabolites, the recovery rate ranging from 70--85%.
