New Delhi: When the firecrackers rose in smokers on other diwali nights in the capital, Delhi-NCR choked on a dangerous gas cocktail a day after the led festival, with city air quality violated the “severe” category for the first time this season.
Tracking the level of pollution in the citydelhi air quality index is 462 on Friday, far in the severe zone.
This is the worst AQI, the city has seen the day after Diwali since monitoring began in 2015.
Delhi also recorded the sharpest setback at AQI since 2015, from the day before the Dewali (AQI 314) until the following day.
The widespread environment from the command of the Supreme Court which prohibits firecrackers be added to other factors, creating a “perfect storm” dirty air in the region.
Wind direction and low wind speeds facilitate transportation of agricultural fire pollutants from neighboring countries.
The pollution part of the stumps in Aqi Delhi rose from 25% on Thursday to 36% on Friday, so far this season.
Delhi also recorded a moderate fog on Friday morning because the visibility fell to 200 meters in Safdarjung and 350 meters in Palam, conditions that worried the air.
Finally, the low temperature – with a minimum at 15 degrees Celsius – missed pollutants close to the ground, the experts said.
On Thursday, Aqi changed from “very poor” at 4pm to “severe” (414) at 10pm.
Safar, pollution monitoring agency under the Minister of Earth Sciences, said, “Fireworks emissions at night Diwali lowered the air quality from ‘very poor’ to ‘heavy’.” Quiet after the storm Diwali was blamed due to ‘severe’ air in terms of Aqi, this was the worst post-diwali day because the Central Pollution Control Agency (CPCB) began to measure AQI.
Before this, the highest AQI on the post-Diwali day was recorded at 445 in 2016.
Aqi on Divi Day this year was better than in 2020 but was worse than the 2019 level.
Last year too, a complete ban on Firecracker was rejected, with AQI deteriorating from 330 (Very bad) on pre-diwali day to 414 (severe) on the festival day.
Aqi on Diwali in 2019 was 337 (very bad).
The CPCB Central Control Room data shows that the average concentration of 24 hours 24 hours Delhi-NCR is either in the “severe” category of a multilevel response action plan because it passes 500 and 300 micrograms per cubic meter for more than 14 and 20 hours.
, each.
The average PM10 was 545.3 micrograms per cubic meter and PM2.5 was 425.5 micrograms per cubic meter.
PM10 and PM2.5 standards are 100 and 60 micrograms per cubic meter, respectively.
“Suddenly this year’s setback was associated with very calm conditions, changes in wind, low ventilation coefficients and firecracks.
Although the increase in trends in pollutant concentration such as PM2.5 and PM10 was observed since November 3 nights, major changes were observed after 8pm On Diwali, when fireworks begin.
The quality of the air around Delhi is already in the ‘very poor’ category because of the accumulation of pollutants in the air warehouse, “the Delhi pollution control committee said.
Anumite Roychowdhury, Executive Director of Research and Advocacy, Science and Environment Center, said, “The first severe smog episode this season was observed when all the unfavorable weather conditions, increased biomass burning share and the use of firecracker.” However, the Indian Meteorology Department (IMD) has expected strong winds with a speed of 25-35kmph on Saturday and Sunday, air quality tends to increase.
Safar said on Friday, “the local wind has taken since morning and now the dispersion is expected Only from November 7 nights but Aqi will fluctuate in the “very bad” range.
