Abstract
Oral administration to a dairy cow of Furadan insecticide (2,2-dimethyl-2,3-dihydro-7-benzofuranyl N-methylcarbamate) labeled with carbon-14 on the carbonyl produced in the milk certain radioactive materials which were not Furadan metabolites. The data suggest that these products were natural milk constituents containing only the carbon-14 atom from the Furadan molecule. Carbon-14-labeled carbon dioxide formed by the hydrolysis of the carbamate insecticide is the apparent precursor of these radiolabeled constituents of the milk.Keywords
