The fireworks during Diwali festive celebrations can cause short time air pollution, particularly in urban areas. In India, Diwali festival is celebrated every year during late October or early November. This festival is related to the bursting of firecrackers especially in Nighttime/early morning hours which leads to ambient air contamination. It releases a high amount of gaseous substances (NOx, CO, SO2 & O3) and particulates. The study was conducted in three consecutive days of November 2015, October 2016 and October 2017 in busy and densely populated areas of Tiruchirappalli city. The carbon monoxide (CO) level was measured at five locations of the city during morning, afternoon, evening and night times. The high amount of CO was recorded during Diwali day at Thennur residential areas in the year of 2015 and 2016. All the results indicated that the CO levels from fireworks were high during night time when compared to the day time. Hence, it is recommended that awareness level should be raised so that people may cut down the number of fireworks in future.
