EPA Tightens Limits on Airborne Lead:Are Changes in the Wind for Coating Work?

摘要

On October 15,2008,the Environmental Protection Agency(EPA)made the first revision to the National Ambient Air Quality Standards(NAAQS)for lead since the standard was established in 1978.The revised standard reduces the allowable ambient airborne lead level by a factor of 10:from 1.5 micrograms of lead per cubic meter of air(mu g/m~3)to 0.15 mu g/m~3.The revision is effective January 12,2009.EPA's action established both the primary standard(intended to protect public health)and the secondary stan-dard(designed to protect public welfare and the environment)at the same level.
