contribute to dry conditions and drive wildfires in some areas.159 Wildfire smoke contains particulate matter, carbon monoxide,
nitrogen oxides, and various volatile organic
compounds (which are ozone precursors) 37and can significantly reduce air quality, both locally and in areas downwind of fires.38, 39,40,41,42
Gaseous pollutants that
contribute to the formation of ABCs are NOx (
nitrogen oxides), SOx (sulfur oxides), VOCs (volatile organic
compounds), CO (carbon monoxide), CH4 (methane), and O3 (ozone).
