Abstract
Dentine lead levels were measured in 760 asymptomatic school children from two school districts, one considered high risk for lead exposure, one considered low risk. Elevated levels were found in black children living in deteriorated housing and in those white children from housing in good repair who lived and attended school in proximity to major manufacturer of paint and lead products.
