Integrated Science Assessment (ISA) for Lead (Final Report, Jul 2013)

Notice

[UPDATE] EPA made available a memo regarding a study assessed in the 2013 ISA for Lead. In addition, in May 2014, EPA reposted the final assessment with an errata sheet and corrections.

Abstract

EPA announced the availability of the final report, Integrated Science Assessment (ISA) for Lead (Pb). This document represents a concise synthesis and evaluation of the most policy-relevant science and will ultimately provide the scientific bases for EPA’s decision regarding whether the current standards for Pb sufficiently protect public health and the environment.

Lead is one of six principal (or “criteria”) pollutants for which EPA has established NAAQS. Periodically, EPA reviews the scientific basis for these standards by preparing an Integrated Science Assessment (ISA) (formerly called an Air Quality Criteria Document). This ISA final report provides a concise review, synthesis, and evaluation of the most policy-relevant science to serve as a scientific foundation for the review of the NAAQS. The CASAC, an independent science advisory committee mandated by Section 109 (d) (2) of the Clean Air Act, is charged with independent scientific review of EPA's air quality criteria.
