In brief, the AQI is a number, according to which pollutants are present along with their concentration and health responses. The level is multiplied by the emissions of these eight key air pollutants – Particulate Matter (PM2.5, PM10), Ozone (O3), Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Sulphur Dioxide (SO2), Lead (Pb), and Ammonia (NH3) – and then summed up for creating the cumulative pollution.
Air Quality Index India
- Launch in 2014, it is under Swachh Bharat Abhiyan:
- National Air Quality Index at New Delhi.
- An expert group formed by CBPC recommended AQI scheme for India.
- Continuous monitoring in six cities of India for getting the real time data.
Instruments used for Measurement of Air Quality
- Some instruments used for measurement of air quality include PCE-RCM 05, PCE-RCM 8, PCE-HFX 100.
- Now, AQI calculations average concentration of the air for a particular time interval.
Understanding Specific Issues:
PM 2.5 and PM 10 are parameters co
