THE AMBIENT AIR QUALITY CHANGES DURING DIWALI FESTIVAL IN BHOPAL CITY

摘要

Diwali the “festival of lights” is celebrated by bursting a large quantity of fire-crackers. Bursting of fire-crackers deteriorates ambient air quality by releasing suspended particulate matter (SPM) and respirable suspended particulate matter (RSPM), consisting of metal oxides along with carbon particles, poisonous/toxic gases in atmosphere. Among the gases released are oxides of nitrogen, oxides of phosphorous, carbon monoxide, carbon dioxide and sulphur dioxide. This paper tries to investigate the air quality changes during Diwali festival in Bhopal by comparing ambient air quality of Diwali days with the ambient air quality of Diwali days of the same month in which Diwali was celebrated in 2011, 2012, 2013 2014. Determines the increase of the air pollution (i.e., SPM, RSPM, SO2 and NOX) during Diwali. The effect of bursting of fire-crackers on ambient air quality. Use of AQI (Air Quality Index) to determine the ambient air quality.
