New Delhi (NVI): The national capital’s air quality index (AQI) remained in the “severe” category for the fifth consecutive day with the AQI being recorded at 459 this morning.
According to India Meteorological Department’s environment research centre, a major improvement in Delhi-NCR’s air quality was highly unlikely in the coming days.
In order to keep the pollution in check, the National Green Tribunal (NGT) today imposed a total ban on the sale or use of all kinds of firecrackers in the National Capital Region (NCR) from November 9 midnight to November 30 midnight, saying “celebration by crackers is for happiness and not to celebrate deaths and diseases”.

The neighbouring cities of Faridabad, Ghaziabad, Noida, Greater Noida, and Gurugram also recorded “severe” air quality.
An AQI between zero and 50 is considered “good”, 51 and 100 “satisfactory”, 101 and 200 “moderate”, 201 and 300 “poor”, 301 and 400 “very poor”, and 401 and 500 “severe”.
