The metabolism, excretion, and tissue distribution of P32_ lauded Bayer 21/199 have been studied following spray application of two Hereford bulls. Only low levels of radioactive compounds were found in the blood, and these behaved like polar degradation products. The compound appears to have been sparingly absorbed, about 2.4 (suspension) and 6.3% (emulsion) of the applied dose being accounted for in the urine of the two animals 2 weeks after treatment. At that time only very low levels of organo-soluble compounds which behaved like 21/199 were present in the tissues, but a considerable residue of unchanged 21/199 was present externally.
