title: Absorption and elimination kinetics of 32P malathion in the hen.
abstract: A method for the separation of urine and faeces in the hen was developed and the biological fate of 32P malathion, following a single oral dose of 262.40 mg/kg body weight was studied. The results suggested that the compound was rapidly absorbed from the gastrointestinal tract; significant quantities being detected in the plasma and whole blood 1/2 hr after ingestion. Total 32P was eliminated in the urine by apparent first order kinetics with an average half-life of 5.7 hrs. The cumulative urinary and faecal data revealed that 93% of the 32P is excreted via the urine within 48 hrs, thus indicating that the compound is almost completely absorbed. It is therefore concluded that accumulation in the system is unlikely.
