From an article found on helium.com:
Air quality is simply the concentration of pollutants and particles in the atmosphere and there are a variety of ways to measure it. Many people are familiar with the air quality indexes produced by countries to indicate when air pollution might be a problem for vulnerable groups.
In the United States the air quality index is production by the Environment Protection Agency (EPA) and in Canada by Meteorological Service of Canada. (MSC) Like most other countries they only measure five major pollutants: ground-level ozone, particulates, sulphur dioxide, carbon monoxide and nitrogen dioxide.
