Recent evidence suggests that children suffer adverse health effects from BLLs substantially lower than 10 µg/dL. Moreover, there is no level of exposure of lead that has found to be safe for children. Consequently it is important not only to eliminate the prevalence of children with elevated BLLs (i.e. ≥ 10 µg/dL), but to also reduce the central measure of BLLs in the target population. Specifically, the addition of sub-objective b focuses attention on reducing the geometric mean of BLLs in young children.
