Citing a TMC report, the official said there was an 11.1% increase in air pollution levels on Lakshmi Puja day compared to pre-Diwali levels, while particulate matter (PM) levels increased to 139 ug/m3.
"The air quality index (AQI) was 141 before Diwali and increased to 157 during the festival period. There was also a 3.2 per cent increase in noise levels during Diwali," he added.
