A lead-induced behavioral disorder

Research output: Contribution to journalArticlepeer-review


Mice were exposed to lead from birth by substituting solutions of lead acetate (2, 5, and 10 mg/ml) for the drinking water of mice 12 hours after parturition. Controls received equal concentrations of sodium acetate. There were no deaths in mothers or offspring due to treatment, but growth and development were retarded in the lead-treated offspring. It has recently been suggested that lead exposure may account for some incidences of hyperactivity and retardation in children. Activity of offspring was measured between 40 and 60 days of age for four consecutive days. Treated mice were more than three times as active as age-matched controls. These studies show that chronic ingestion of lead can produce a significant behavior disorder in mice.
