The purpose of this study is to
evaluate the association between elevated blood lead levels and
parameters of immune function in children. Approximately 100
children identified as having blood lead >10 ug/dL or blood lead
levels <5 ug/dL and participating in the ongoing lead screening
programs in the Tri-State Mining District will constitute the study
and comparison groups. Blood specimens will be obtained to measure
lead, complete blood count, EP, ZPP, antibody titers, and an immune
panel. A repeat test a month later will examine intra-personal
immune tests stability and evaluate the relationship between immune
results....
