Children under the age of six are more likely to be exposed to lead because of their bodies rapid development, propensity to put their hands or other objects in their mouths, and increased risk of lead poisoning.
What factors can increase lead absorption from ingestion?

The mean blood lead level of the children at age 11 was 10.99 micrograms per deciliter of blood, slightly higher than the historical level of concern for lead exposure. The study found that for each 5-microgram increase in blood lead, a person lost about 1.5 IQ points.
