The Influence of Declining Air Lead Levels on Blood Lead-Air Lead Slope Factors in Children

摘要

Background: It is difficult to discern the proportion of blood lead (PbB) attributable to ambient air lead (PbA), given the multitude of lead (Pb) sources and pathways of exposure. The PbB-PbA relationship has previously been evaluated across populations. This relationship was a central-consideration in the 2008 review of the Pb national ambient air quality standards.
