India has come up with an Air Quality index India (AQI) to give an aggregate sense of the quality of air.
The formulation of the index was a continuation of the initiatives under Swachh Bharat Mission envisioned by the present Prime Minister of India.
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.
