In India, the evaluation of the National Air Quality Index (AQI) relies on monitoring a specific total number of key atmospheric pollutants. What is this total count of parameters considered for determining the AQI?
Correct Answer :
8
Solution :
The correct answer is 8.
The National Air Quality Index (AQI) was launched in India in October 2014 under the Swachh Bharat Abhiyan to provide a simple, easily understandable tool for reporting air quality to the general public. It transforms complex air quality data of various pollutants into a single number, nomenclature, and color scheme.
To evaluate the National Air Quality Index in India, a total of 8 key atmospheric pollutants are monitored:
1. Particulate Matter 10 (PM10)
2. Particulate Matter 2.5 (PM2.5)
3. Nitrogen Dioxide (NO2)
4. Sulfur Dioxide (SO2)
5. Carbon Monoxide (CO)
6. Ozone (O3)
7. Ammonia (NH3)
8. Lead (Pb)
Hence, the total count of parameters considered for determining the AQI is 8.
