New Delhi:

Three days after Diwali, fireworks, beard burning and local sources of pollutants continue to indicate that Delhi NCR is still experiencing severe air quality on Saturday.

Despite slight improvements from severe to serious over the last 24 hours, the air quality of Delhi-NCR has started to deteriorate again by Saturday evening due to the increase in pollutants.

4:00 pm Delhi's Air Quality Index (AQI) is about 401, 6:00. It was submerged at 406 – both were considered "gross". It was AQI 423 in Delhi at 4 pm on Friday.

Undesirable weather conditions, such as very low wind speeds and low temperatures, prevent PM2.5 and PM10 or particles with diameters less than 2.5 and 10 mm from dispersing.

The average concentration of PM2.5 and PM10 in Delhi rose to 262 and 432 at 262 and 424 micrograms per cubic meter at 4 pm. Meanwhile, the PM2.5 and PM10 concentrations in the NCR 49 regions increased by 256 and 409 at 4 pm and by 261 and 416 at 6 pm.
