Under the Clean Air Act, the EPA identifies criteria pollutants and sets health-based standards for outdoor air quality. National Ambient Air Quality Standards (NAAQS) have been set for six criteria pollutants:

  • Carbon monoxide (CO)
  • Sulfur dioxide (SO2)
  • Lead (Pb)
  • Nitrogen dioxide (NO2)
  • Ground-level ozone (O3)
  • Particulate matter (PM10 and PM2.5)

In the Charlotte area, we are primarily concerned with levels of ozone and PM2.5. Ground-level ozone and particulate matter are the main ingredients in smog. Smog can have harmful effects on human and animal health, as well as plant life and aesthetics.
