Answer:
The AQI measures five criteria air pollutants (particulate matter, sulfur dioxide, carbon monoxide, nitrogen dioxide, and ozone), and converts the measured pollutant concentrations in a community's air to a number on a scale of 0 to 500.You can think of the AQI as a yardstick that runs from 0 to 500. ... When AQI values rise above 100, air quality is considered unhealthy – at first for certain sensitive people, then for everyone as AQI values get higher. The AQI is most commonly used to describe ground-level ozone levels*.
