Fine particulate matter, also called PM2.5, is an air pollutant with significant public health impacts that is regulated under the federal Clean Air Act; PM2.5 is also the primary air pollutant of concern across much of the western United States. PM2.5 pollution has many sources: industrial and agricultural activities, power generation, transportation, and construction. In addition to these anthropogenic sources, wildfires are also a major source of PM2.5. In contrast to anthropogenic sources, pollution from wildfires is sporadic, intense, and may impact urban areas hundreds to thousands of kilometers downwind. State agencies are tasked with developing emission control strategies to minimize public exposure to PM2.5 and maintain compliance with Federal air quality standards. The development of effective and efficient emission controls for anthropogenic sources requires quantitative knowledge of the contribution of wildfires to air pollution in population centers.
