Metabolism of lead-210 in juvenile and adult rhesus monkeys (Macaca mulatta)
Bull Environ Contam Toxicol.
1978 Jun.
Abstract
Experiments were conducted measuring the gastrointestinal absorption and elimination of a single dose of lead-210 acetate in infant and adult rhesus monkeys. Urinary and fecal excretion of absorbed lead was followed for 23 days. Infant monkeys eliminated less and absorbed more orally administered lead. Adult animals excreted more absorbed lead in feces, while urinary excretion between adults and infants was similar. Increased absorption of administered lead and reduced fecal excretion of absorbed lead resulted in significantly greater body burden of lead-210 in infant animals. Blood lead values were increased in the infant animals, and were inversely correlated with body burden and percent absorption of ingested lead.
