Description:
Background:
The Clean Air Act mandates periodic review of the National Ambient Air Quality Standards (NAAQS) for six common air pollutants, also referred to as criteria pollutants, including lead. Under the review process, EPA's Office of Research and Development develops a criteria document -- a compilation and evaluation by U.S. EPA scientific staff and other expert authors of the latest scientific knowledge useful in assessing the health and welfare effects of the air pollutant. In this case, the Lead Criteria Document presents the latest available pertinent information on atmospheric science, air quality, exposure, dosimetry, health effects, and environmental effects of lead. In developing criteria documents, EPA must consider the advice of CASAC.
History/Chronology:
The following is a brief history of the development of the Air Quality Criteria for Lead.
