A thick layer of smog prevailed in Patna in the morning hours as the pollution level in the state capital slipped to the lower end of “very poor” category on Friday. The overall air quality index (AQI) in the city stood at 378, as per the daily bulletin released by the Central Pollution Control Board (CPCB).
The air quality early warning system for Patna under the ministry of earth sciences of the central government predicted that the air quality will remain “very poor” on Monday owing to calm wind, fall in temperature, and moisture, which are unfavourable for dispersion of pollutants in the air.
