The air quality in Delhi was classified as “hazardous” near Janpath in the capital early on Friday, a day after Diwali celebrations.
According to the news agency ANI, the particulate matter (PM) 2.5 concentration in Janpath was 655.07 on Friday morning.
PM 2.5 values above 380 are classified as “serious” by the government.
According to various news sources, the Delhi government’s entire prohibition on the selling and bursting of firecrackers, including green crackers, on Diwali day was overturned after individuals were observed celebrating the celebration by exploding crackers on the streets.
Field fired and stubble burning
The bursting of crackers exacerbated the city’s deteriorating air quality, which was already being exacerbated by field fires and stubble burning, according to the ANI report.
According to the article, several people in the national capital complained of itchy throats and watery eyes after a heavy blanket of fog covered the Delhi skies.
“Delhi’s total air quality has slipped into the very poor category. It will continue to decline and may enter the “extremely poor” to “severe” category by tonight,” according to the System of Air Quality and Weather Forecasting and Research’s (SAFAR) air quality forecast for Delhi this Diwali.
“If firecrackers are burned even 50 per cent of last year then PM2.5 will enter ‘severe’ category by midnight and shoot up rapidly by today early morning with AQI even crossing 500,” it further said.
According to SAFAR
The two major factors contributing to the pollution on Friday were extremely calm wind conditions in Delhi and a 25% stubble share (2,293 fire count).
According to the SAFAR model forecast, the stubble share of pollution is expected to reach approximately 35% on the day and nearly 40% on November 6 and November 7.
“Relief is forecast only from the evening of November 7,” it added, “although AQI will vary within the Very Poor category.”
According to data from the Central Pollution Control Board (CPCB), Delhi’s air quality index was 382 on Thursday, remaining in the “extremely poor” category.
