U.S. Air Quality Standards for Lead Now 10 Times Stronger
" EPA dramatically strengthened the nation's air quality standards for lead, improving public health protection, especially for children. The new standards tighten the allowable lead level 10 times to 0.15 micrograms of lead per cubic meter of air (ug/m3).

"America's air is cleaner than a generation ago," said EPA Administrator Stephen L. Johnson. "With these stronger standards a new generation of Americans are being protected from harmful lead emissions."

This decision marks the first time the lead standards have changed in 30 years. EPA strengthened the standards after a thorough review of the science on lead, advice from the Clean Air Scientific Advisory Committee, and consideration of public comments. The previous standards, set in 1978, were 1.5 ug/m3.

EPA's action sets two standards: a primary standard at 0.15 ug/m3 to protect health and a secondary standard at the same level to protect the public welfare, including the environme.."nt.
