Calculating the Air Quality Index. The AQI is calculated by converting measured pollutant concentrations to a uniform index which is based upon peer-reviewed scientific evidence of the health effects associated with a pollutant.
The higher the AQI value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of 50 represents good air quality with little potential to affect public health, while an AQI value over 300 represents hazardous air quality.
