How is the AQI calculated?

Question

Accepted Answer

AQI is calculated based on the levels of five major air pollutants: ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide.

The AQI is calculated for each of the five major air pollutants based on their concentration levels in the air.
The highest AQI value calculated for any individual pollutant determines the overall AQI value for a specific location.
Each pollutant has its own AQI scale, ranging from 0 to 500, with specific health implications associated with different AQI levels.
The AQI is categorized into different levels such as Good, Moderate, Unhealthy, Very Unhealthy, and Hazardous based on the overall AQI value.
For example, if the AQI values for ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide are 50, 60, 40, 30, and 70 respectively, the overall AQI value would be 70.
