Total radiocarbon transfer to the lungs ranged from 9 to 15% of that in the tobacco burned during a smoking process involving eight 5-ml puffs. Exhalation of 14C residues during this time was 24 to 30% of that inhaled with all insecticides except carbofuran, of which 42% of the residues was exhaled. After 5 hr, total exhalation of the consumed radiocarbon was 35% for parathion, 65% for carbofuran, and approximately 50% for the other products. The nature of the 14C residues inhaled, their urinary and fecal excretion, and their deposition in and dissipation from various organs and tissues are presented.
