The pollutant concentration determines the air quality of the environment. High concentrations of pollutants can have severe negative impacts on the ecological environment and humans. Short and long-term air qualities are important in determining the liveability of a city. Air pollutants include soot, total suspended particulate matter, respirable suspended particulate matter (floating dust), nitrogen dioxide, sulphur dioxide, carbon monoxide, ozone and volatile organic compounds. Carbon dioxide is not considered a pollutant.
