The Air Quality Index (AQI) is an "index" determined by calculating the degree of pollution in the city or at the monitoring point and includes five main pollutants - particulate matter (see SIM-10-2008), ground-level ozone, sulfur dioxide, carbon monoxide and nitrogen dioxide. Each of these pollutants have an air quality standard (which varies by country) which is utilized to calculate the overall AQI for the city. Simultaneously, one can also establish the limiting pollutant(s), resulting in the estimating AQI.
