What is Air Quality Index (AQI) and Why it's Important

The Air Quality Index (AQI) is an index that measures the quality of air in different locations on a daily basis. The AQI is used by the government agencies of different countries to inform the public about the AQI data, make them aware of how good or bad the quality of air in their environment is, and also provide them with measures of precaution.

The rise of air pollution due to the excessive burning of fossil fuels and false treatment of wastes has resulted in the prevalence of hazardous diseases. That's why AQI has become an area of concern nowadays. It helps to take bold steps toward the safety of the environment as well as humans, both at the individual and community levels.

How AQI is Calculated

The Environmental Protection Agency has created 5 major air pollutants criteria on the basis of which AQI is calculated. These pollutants include Ground-level Ozone, Particulate Matter, Carbon Monoxide, Sulphur Dioxide, and Nitrogen Dioxide. There are defined ranges for levels of concern and they are denoted with different colors. However, these ranges and the process of calculating AQI varies from country to country. In India, it's calculated by averaging the data received from sensors.
