Study of the impact of Diwali on the air quality of Dehradun

Abstract

The study focused on analyzing the levels of air quality parameters across 2 areas of Dehradun – Clock Tower & Nehru Colony, both pre and post Diwali 2021. The data analyzed showed higher concentrations across all parameters during the 5-day period around Diwali. While the concentrations of SOx & NOx were within National Ambient Air Quality Standards of the Central Pollution Control Board, PM10 & PM2.5 concentrations exceeded the standards. It was also noted that the levels almost reached back to pre-Diwali levels within a week post-Diwali. These could impact both plants and animals with devastating effects, causing severe respiratory problems.
