How is air quality measured?
Air quality is measured for many pollutants, including: particulate matter (PM 2.5), ground-level ozone, pollen (PM 10), carbon, sulfur dioxide, and nitrogen oxide. The Air Quality Index (AQI), a tool created by the EPA, measures both ozone pollution and PM 2.5 in ranges from 0-300+. Air quality advisories are issued when the AQI exceeds, or is expected to exceed, a value of 1001.
What is Particulate Matter 2.5?
Particulate matter, which comes from wildfire smoke, is composed of tiny liquid droplets or microscopic matter so small they penetrate deep into our lungs and can even enter our bloodstream.
What are the health impacts?
