The air quality index of the millennium city of Gurugram entered the dangerous zone due to excessive use of crackers during Diwali and burning of crops in rural areas of Haryana.

Gurugram recorded 377 cubic meter percolate matter 2.5 (PM 2.5), higher than normal days, which is same as Delhi.

“Gurugram has two monitoring stations — at Vikas Sadan in the Civil Lines and Gwal Pahari. The PM 2.5 level recorded was 374 and 380, respectively, at these places. Last year, the figure had entered the dark zone, which is above 400 cubic meters,” said Kuldeep Singh, regional officer (North zone) of the Haryana State Pollution Control Board.

As the temperature in the region had fallen by 2-3 degree Celsius, it’s not allowing the atmosphere to clear, he said. The haze, formed by toxic gasses emitted by crackers, would not clear until a shower or a sunny sky, he added.
