Air Quality Index(AQI) UPSC NOTE

 What is AQI

  • AQI is a measure of the concentration of certain air pollutants in the air. 

  • These pollutants include particulate matter (PM2.5 and PM10), ozone, nitrogen dioxide, and sulfur dioxide. 

  • The AQI is calculated using a formula that takes into account the concentrations of these pollutants and their potential health effects.

  • The higher the AQI, the more polluted the air and the greater the health risk

  • People with respiratory problems, such as asthma, are especially sensitive to the effects of air pollution.

AQI range

  1. Good (0-50): Green

  2. Moderate (51-100): Yellow

  3. Unhealthy for Sensitive Groups (101-150): Orange

  4. Unhealthy (151-200): Red

  5. Very Unhealthy (201-300): Purple

  6. Hazardous (301-500): Maroon

  • The AQI is used to inform the public about the quality of the air in their area.

  • The AQI is calculated by government agencies and is available to the public on websites and mobile apps.
