The National Capital continued to experience ‘very poor’ air quality on November 23 morning, with an air quality index (AQI) of 324, as per the System of Air Quality and Weather Forecasting And Research (SAFAR-India).
As per the data from the Central Pollution Control Board (CPCB) recorded at 6:00 am on November 23 morning, the Air quality index at Anand Vihar was at 387 (very poor); At ITO, Delhi, it was 343 (very poor), while the AQI at Wazirpur, Delhi, was 422 (severe), at RK Puram, it was 415 (severe).
Similarly, the Air Quality Index recorded at 7:00 am on November 23 morning at Okhla Phase-2, Delhi, was 406 (severe).
The Air Quality Index from 0 to 100 is considered good, while from 100 to 200, it is moderate; from 200 to 300, it is poor and from 300 to 400, it is said to be very poor; and from 400 to 500 or above it is considered as severe.
The Air Quality Index is a tool for effectively communicating air quality status to people in terms that are easy to understand. It transforms complex air quality data of various pollutants into a single number (index value), nomenclature and colour.
With an improvement in the air quality in Delhi last week, the CAQM (Commission for Air Quality Management) on November 18 revoked the restrictions that were imposed under GRAP 4, permitting trucks and buses except for BS-3 and BS-4 petrol and diesel vehicles to enter the city and lifting the ban on ongoing construction activities.
The Supreme Court suggested on November 21 that the farmers who engage in stubble burning be deprived of the Minimum Support Price (MSP) benefits as a part of the economic repercussions of their actions.
The Top Court was hearing a plea pertaining to rising air pollution in Delhi-NCR.
