Phosphorus32-labeled phosphoric acid and O,O-diethyl phosphorodithioic acid were fed at 100 p.p.m. in the diet of laying hens for 7 days. The liver, kidney, and bone accumulated more radioactive materials than the blood, brain, breast, fat, feathers, gizzard, or skin. Egg yolk contained more acid equivalents than the shell or white. Acetonitrile-soluble residues were detectable in the feces, egg yolk, and liver. About 46% of the phosphoric acid and 36% of the diethyl phosphorodithioic acid consumed in the feed were present in the feces 14 days after treatment of hens. The phosphoric acid and diethyl phosphoric acid exhibited solubility properties characteristic of many organophosphate insecticides.
