This year, air and noise pollution levels in the city on Diwali were less than previous years, even though sound levels exceeded the permissible limit at all locations.

In its report, the Chandigarh Pollution Control Committee (CPCC), which monitored air quality and noise levels in the city, says that maximum air and noise pollution was recorded in Manimajra.

CPCC monitors pollution levels at seven locations in the city — sectors 9, 29, 22, Panjab University, Kaimbwala village, Manimajra and Kajheri village.

While every year pollution levels are monitored a day before and on the day of Diwali, this year they were monitored a day after the festival as well.

CPCC member secretary P J S Dadhwal said residents used fewer crackers this year, ensuring a greener Diwali.

“The UT Administration and the Chandigarh Pollution Control Committee took a number of steps to check air and noise pollution on Diwali. Sustained campaigns launched through eco-clubs of schools and anti-cracker rallies seemed to have worked,” Dadhwal said.

Noise pollution at all locations, except Manimajra and Sector 9, was less than previous year. The noise levels were highest between 8 to 11 pm at most of the locations.

Against the permissible noise level of 55 dB(A), from 6 am to 10 pm, and 45 dB(A), from 10 pm to 6 am, the highest noise level was 82 dB(A) (in Sector 22). In Kaimbwala village, the highest noise level was 66.2 dB(A). Elsewhere, it was 78.1 dB(A) in Panjab University, 79.2 dB(A) in Kajheri, 79.6 dB(A) in Manimajra and 72.1 dB(A) in Sector 9.
