EPA Revises the National Ambient Air Quality Standards for Particle Pollution
December 14, 2012 - The U.S. Environmental Protection Agency took important steps to protect the health of Americans from particle pollution by strengthening the annual health National Ambient Air Quality Standard for fine particles (PM2.5) to 12.0 micrograms per cubic meter (ยตg/m3). The agency also retained the existing standards for coarse particle pollution (PM10).
