Reduction in air quality during festival activity due to combustion, in Manali industrial area of Chennai city, is highlighted here, by considering the meteorological factors (wind velocity, wind speed, wind direction, humidity, stability class and mixing heights) for the month of October to December. The ambient air quality parameters for particulate matter PM2.5, CO, SO2 and NOx were collected from the Manali industrial area for the year 2019 to 2022 for the month of January. The meteorological data were executed using WR plot software and wind-rose diagrams were prepared. The data obtained were compared with the Central Pollution Control Board (India) norms and the change in the ambient air quality was identified and measures to overcome the air impact during Bhogi festival day is suggested.
