PM 2.5 are fine inhalable particles with a diameter that is generally 2.5 micrometres or less and are hazardous for health.
The national capital's PM2.5 levels hit a peak by midnight on Diwali this year, which was 13 per cent higher than the peaks observed last year and in 2022, a recent analysis showed.
Diwali night this year also saw higher nitrogen dioxide (NO2) levels, which indicates high traffic congestion, a report by Centre for Science and Environment (CSE) said.
The research organisation's report also said that unlike previous years there was a quick build-up of PM2.5 levels and dissipation the next day.
