U.S. EPA proposes changes to NAAQS for lead.

U.S. EPA is proposing to modify the national ambient air quality standards for lead.  Lead that is emitted into the air can be inhaled or, after it settles out of the air, can be ingested. Ingestion is the main route of human exposure. Once in the body, lead is rapidly absorbed into the bloodstream and can affect many organ systems.  More than 6,000 studies since 1990 have examined the effects of lead on health and the environment. Evidence from health studies indicates that lead in the blood can cause harm at much lower levels than previously understood. EPA will accept public comment for 60 days after the proposal is published in the Federal Register. The agency will hold two public hearings on June 12, 2008: one in St. Louis and one in Baltimore. EPA must issue a final decision on the lead standard by Sept. 15, 2008.  Details about the proposal and public hearing information:
