Abstract
THE maximum daily permissible intake of lead, not leading to accumulation, has been estimated at 300 μg for children.1 Above that amount, the body burden of lead presumably increases. In early infancy, dietary lead may be a major common source of this heavy metal. Accordingly, the purpose of this study was to estimate the probable dietary intake of lead during early infancy from milks fed to infants.MethodsCans from different lots of the major national brands of infant formulas and evaporated milks were purchased in their original containers during late 1971 and early 1972 from retail stores in Connecticut. . . .
