The Environmental Epidemiology of Human Lead Exposure

This chapter deals with epidemiological studies of human Pb exposure using biomarkers of such exposure. These studies deal with various parameters and correlates of human Pb exposure from demographic and environmental measurements. While much of the available data has been generated in the United States, illustrative international studies are also presented where relevant. Later chapters deal with epidemiological studies of dose—response relationships for Pb and an array of toxicity outcome measures addressing organ and tissue toxicides. [Pg.345]

A second form of epidemiological study uses inferential statistical analyses where the epidemiology is of two types exposure biomarkers such as blood Pb studied for links to environmental sources and pathways, and studies to ascertain Pb-containing media that may be significant contributors to toxic exposures and toxicity in human populations. [Pg.345]

Survey and screening epidemiological data include the various population and subpopulation surveys and screenings of socioeconomic and demographic strata carried out in the United States and elsewhere over the past several decades. Additional cumulative aspects of these studies addressed here are the epidemiological and public health messages for Pb exposure [Pg.345]

National exposure surveys discussed here include demographic and socioeconomic snapshots of the prevalences and incidences of biomarkers of Pb exposiues with reference to distributions of measured biomarkers of Pb exposure and their variation, gathered by intensive measurement efforts stratified along multiple socioeconomic and demographic lines.
