摘要

This document is the first volume of the draft report Lead Human Exposure and Health Risk Assessments for Selected Areas. This volume describes the quantitative human exposure and health risk assessments being conducted to inform the U.S. Environmental Protection Agency's (EPA's) current review of the National Ambient Air Quality Standards (NAAQS) for lead (Pb). The draft risk assessment report is being provided to CASAC and the public for review in advance of a public meeting of the CASAC Pb panel planned for August 28-29, 2007. Following that meeting, we will take CASAC and public comments into account in preparing the final document. We plan to complete the final risk assessment report in October, 2007.
