the EPA thresholds for hazardous and unhealthy air quality. To put it into perspective, an area deemed to be unhealthy typically has 65 micrograms of smoke particulate per cubic meter, while an area deemed to be hazardous has anymore than 250 micrograms per cubic meter. Normal levels in Fairbanks, Alaska are typically 10 micrograms per cubic meter. The main issue with smoke particulate is not the smoke itself but the matter that is mixed in. Wildfire smoke is usually made up of acids, chemicals, metals, soil/dust, and pollen/mold spores.
