Delhi Air Pollution: 7 In 10 Families Have At Least 1 Person Suffering, Finds Survey

Delhi's PM2.5 levels hit a peak by midnight on Diwali this year, which was 13% higher than the peaks observed last year and in 2022, a recent analysis by the Centre for Science and Environment (CSE) showed.

“The Diwali night this year had higher nitrogen dioxide (NO2) levels that indicate high traffic congestion,” the CSE report said.

The research organisation's report also said, unlike previous years, on Diwali night in Delhi, there was a quick buildup of PM2.5 levels and dissipation the next day.
