How is Air Quality Determined?

Each day, concentrations of various air pollutants are measured in areas across Idaho. A federal standard, or limit, has been estabished for each air pollutant. These limits are based on the health effects of the pollution and vary by type of pollutant. After the amount of pollution is measured, it is compared to the federal standard. To make it easy to compare the various pollutants and determine the air quality, the U.S. Environmental Protection Agency (EPA) developed the Air Quality Index, or AQI.
