The sources of pollutants were assembled into five categories for the emissions trends graphs that can be found at Georgia's Air Quality Trends website (link below): fires, industrial and other processes, stationary fuel combustion, off-road vehicles, and on-road vehicles. The major contributors for CO and NOx emissions are on-road mobile sources, and both of these pollutants have a downward trend beginning in 2003. The largest contributors of SO2 are stationary fuel combustion sources, and SO2 emissions have decreased dramatically since 2007. Both wildland and prescribed fires significantly contribute to PM2.5 and VOC emissions, while industrial and other processes also play a major role, particularly in increasing VOC and PM10 levels. In both 2011 and 2017, there were wildfires in the Okefenokee Swamp area that caused an uptick in the data for those years. Additionally, wildfires across the country and Canada have affected Georgia for the last few years.
