What is the Air Quality Index (AQI)?

The Air Quality Index (AQI) is used to communicate the quality of the air in a specific location at a given time. It is a standardized system developed by environmental agencies to help the public understand and monitor the potential health risks associated with different levels of air pollution.


The AQI is typically calculated based on the concentration levels of various air pollutants, including: ground-level ozone, particle pollution (also known as particulate matter), carbon monoxide, sulfur dioxide, and nitrogen dioxide. Each pollutant has its own AQI value, which is typically based on the pollutant’s potential to cause adverse health effects at different concentrations. Ground-level ozone and airborne particles are the two pollutants that pose the greatest threat to human health in this country.
