According to analysis by the Delhi pollution control committee (DPCC), people in the national capital breathe the worst air between November 1 and November 15 every year.
Faridabad (460), Ghaziabad (486), Greater Noida (478), Gurugram (448) and Noida (488) also recorded severe air quality at 4pm.

According to the Central Pollution Control Agency (CPCB), the concentration of an average of 24 hours of fine particles that damage the lungs known as PM2.5 in Delhi-NCR crossed the 300 mark around midnight and stood in 381 micrograms per cubic meter at 4 o’clock Afternoon (Friday), more than six times a safe limit of 60 micrograms per cubic meter.
PM10 levels are recorded at 577 micrograms per cubic meter.
According to the action plan Responses (Grap), air quality is considered in the emergency category if the PM2.5 and PM10 levels continue to be above 300 micrograms per cubic meter and 500 micrograms per cubic meter each for 48 hours or more.
Officials from the Meteorology Department of India (IMD) said moderate fog and low temperatures in the morning – Delhi recorded a minimum temperature of 12.6 degrees Celsius on Friday – and a quiet wind had trapped pollutants close to the ground.

The Green Tank Tank Center for Science and Environment (CSE) told Wednesday that the ongoing Smog episode was the Emergency of Public Health and could be the longest in four years.
Longer duration of smoke fog this year, although local conditions are relatively lower, perhaps due to the lack of pollution control measures in the city, CSE said in a report.

“This is a new feature in the winter period.
This is mainly due to the mechanism of particle growth due to high humidity at night and increasing moisture in the afternoon may be due to water sprinkling which also increases the air winding capacity.
Because of the usual flow.
PM2.5 particles grow towards PM10 (Sic), “he said.
