The Air Quality Index (AQI) is a measure used to communicate the level of air pollution to the public. It includes several key pollutants that impact human health. The commonly monitored pollutants in AQI include: Particulate Matter (PM2.5 and PM10), Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), Ozone (O3), Ammonia (NH3), Lead (Pb) Benzene (C6H6).
Hence all the four given above are included in AQI measurements.
