DYK what the U.S. Air Quality Index (AQI) is? It is EPA’s index for reporting air quality. EPA has an AQI for five common air pollutants: .✅ Ground-level ozone .✅ Particulate Matter (including PM2.5 and PM10) .✅ Carbon monoxide .✅ Sulfur dioxide .✅ Nitrogen dioxide.🧵

If you are healthy, you're usually not at a major risk from short-term exposures to smoke. Still, it's a good idea to avoid breathing smoke if you can help it. Everyone should take the steps below when wildfires are present.
