AIR QUALITY INDEX:

Traditionally, air quality status has been reported through voluminous data. Thus, it was important that information on air quality is put up in public domain in simple linguistic terms that is easily understood by a common person.

Air Quality Index (AQI) is one such tool for effective dissemination of air quality information to people.

This index is launched under Swacch Bharat Abhiyan in 2014

The Aim is ‘one number- one colour-one description’ for the common man to judge the air quality within his vicinity.

There are six AQI categories, namely Good, Satisfactory, Moderately polluted, Poor, Very Poor, and Severe. 

The proposed AQI will consider eight pollutants (PM10, PM2.5, NO2, SO2, CO, O3, NH3, and Pb) for which short-term (up to 24-hourly averaging period) National Ambient Air Quality Standards are prescribed.
