Inhaled octanal was absorbed from the lungs in a biphasic manner and the greatest concentration of octanal occurred in most tissues at 5 min. Tissue activities calculated on the basis of the administered dose and on the radiolabel retained until the animal was killed indicated a redistribution of the radiolabel as metabolic products after 20 min. The labeled carbon was eliminated in a biphasic manner as 11CO2, which accounted for essentially all of the activity lost by the exposed rats.
