New Delhi: Delhi air quality remains “very poor” for the second day in a row on Wednesday and is likely to take over over the next two days even if there is no firecracker exploding at the gods, the authorities said on Wednesday.
While Safar said air quality might be ‘severe’ on November 5 and 6 if firecrackers were burned, an official from the Indian Meteorology Department said the prediction model did not show AQI achieved “even with higher emissions”.
According to the Central Polution Control Board, the capital recorded an average air quality index of 24 hours (AQI) of 314.
It was 303 on Tuesday and 281 on Monday.
Neighboring cities Faridabad (337), Gurugram (330), Ghaziabad (353) and Noida (327) also recorded very poor air quality.
Aqi between zeros and 50 is considered ‘good’, 51 and 100 ‘satisfying’, 101 and 200 ‘moderate’, 201 and 300 ‘poor’, 301 and 400 ‘very poor’, and 401 and 500 ‘severe’, and 401 and 500 ‘severe’, and 401 and 500 ‘severe’, and 401 and 500 ‘severe’.
The Ministry of Earth Department of Safar Air Quality Sciences said 3,271 agricultural fires contributed eight percent PM2.5 PM2.5 on Wednesday.
It is likely to increase to 20 percent on Thursday and further to 35 to 40 percent on Friday and Saturday with the direction of the wind to the northwest, he said.
The northwest wind brings smoke from agricultural fires in Punjab and Haryana to the national capital.
Last year, the share of the stumps of the propellers in Delhi pollution peaked at 42 percent in 5.
November 2019, the burning of plant residues contributed 44 percent of PM2.5 Delhi pollution in November 1.
“Very calm Delhi wind condition with a small ventilation expected For the next three days, “Safar said.
Under the scenario of zero firecracker emissions, the concentration of PM2.5 Delhi is predicted to be at the top end of the ‘very poor’ category from November 4 to November 6.
“However, even if we consider 50 percent of the burden of Firecracker 2019, even., AQI is predicted to decrease into the ‘severe’ category during that period,” Safar said.
PM2.5 concentration in the national capital can exceed 500 micrograms per cubic meter on November 5.
The safe limit is 60 micrograms per cubic meter.
