The Pinal County Air Quality Index map above shows the most recent ozone and particulate matter (PM10 – particulate matter 10 microns and less in size, PM2.5 - particulate matter 2.5 microns and less in size) levels.  The AQI is a yardstick that runs from 0 to 500 with the higher the AQI value the greater the level of air pollution and thus a greater health concern. The health standard for each pollutant is represented by 100 on the AQI scale. Any AQI value over 100 represents an exceedance of the health standard for that particular pollutant and the air quality is considered to be unhealthy for either sensitive groups (asthmatics), 101 to 150 on the AQI scale or unhealthy for all people (151+ on the AQI scale).  In addition to the AQI values, the ozone and particulate matter concentrations can also be displayed on the map by selecting each pollutant for the "Layers" dropdown menu.
