Diwali, the festival of lights and of course crackers, was passed yesterday with joy and celebration but the next day turned out to be a huge blanket of invisibility.
On Sunday morning, a day after Diwali, the air quality index was 461 and 478 at the ITO area and Anand Vihar respectively. This altered the air quality to the category of “severe” according to Delhi Pollution Control Committee data.
Along with the capital, its neighboring cities including Ghaziabad (483), Greater Noida (439), Noida (466), Faridabad (438), and Gurgaon (424) was the Air Quality Index recorded under the category of “severe”.
The reduced visibility in several areas across Delhi was due to a thick blanket of smog that was developed may be due to excessive burning of firecrackers on Diwali.
The hope of improvement in the quality is expected from the second half of Sunday with a light shower across the capital. Change in the wind direction towards the south-easterly region has reduced the impact of fire on farms on Delhi’s air.
The AQI category for various regions is considered:
Moderate, if lies between 101 and 200
Poor, if lies between 201 and 300
Very poor, if lies between 300 and 400
Severe, if lies between 401 and 500
Serveplus category, if lies above 500
Air quality index for various reasons for PM 2.5 pollutants was stuck at 460 in Pusa, 450 in Lodhi Road, 491 in Ashok Vihar, 475 in Pratapganj, 442 in IDI Airport Area, and 500 in Jahangirpuri.
On Friday, the Air Quality Index was recorded as 339 while it was 414 on Saturday night after the Delhiites ignored the ban on crackers during the festival. This was recorded as the worst AQI in Delhi since Diwali of 2016.
The pollution level was expected to remain in the category of “Severe” for the consecutive three days in 2019 on October 27th with AQI of 337, 368, and 400 for 3 days.
The city was imposed under a total ban on sale as well as the use of firecrackers in the NCR region from 9th November midnight to 30th November midnight by the National Green Tribunal.
The State Pollution Control Board, Pollution Control Committee, and Regional Directory of CPCB have been asked to conduct monitoring on air quality for 7 days after the festival by the Central pollution control board to study the effects of the pollutants during Diwali, on the air quality.
