Chandigarh: Cracker tires rose in smoke in Diwali as air quality derived from ‘satisfying’ to ‘severe’ in a few hours.

After 6pm, it began to deteriorate.
At 10 pm, it was in the severe category in the 22nd sector and at 11pm in the sector 25.
But there was a silver layer.
The average AQI is 115 compared to last year 140 (sector 25 stations 25) on Diwali’s day.
