Wildfire affects air, land and water throughout Oregon. The Oregon Department of Environmental Quality monitors air quality and issues advisories when wildfire smoke degrades air. DEQ also regulates land and water quality during the cleaning up and rebuilding that may follow a wildfire.

Smoke contains very small particles of harmful air pollution known as particulate matter, or PM2.5. These particles are less than 2.5 micrometers in diameter—about 30 times smaller than the diameter of a human hair.
