Delhi's air quality remained in the 'very poor' category due to slow wind speed and high humidity today, authorities said.
The overall Air Quality Index (AQI) was recorded at 322, which comes under the 'very poor' category, according to the Central Pollution Control Board (CPCB) data.
Fourteen areas in Delhi recorded 'very poor' air quality and 14 recorded 'poor' air quality.
Air quality expected to remain same for next 3 days
Air quality is 'very poor' and is expected to remain in the same category with a gradual increase for the next three days as wind speed is slow and humidity is high, which is unfavorable, the Center-run System of Air Quality and Weather Forecasting (SAFAR) said.
"Fire counts from stubble burning declined significantly and hence have a negligible impact," it added.
