Abstract
When a steer was treated orally with 14C-labeled Stauffer R-3828 ( S-(p- chloro- alpha -phenylbenzyl) O, O -diethyl phosphorodithioate), 90% of the administered dose was eliminated in the urine and feces within 20 days. Of this amount, 52.7% was excreted in the urine. The plotted curves for the amounts of radioactive materials in the blood, urine, and feces were very flat, and there were multiple peaks; however, the greatest quantities occurred at either 48 or 96 hr post treatment. The elimination of Stauffer R-3828 or its products was slow compared with the elimination of other oreganophosphorus insecticides.
