摘要：Deepavali festival is distinguished by bursting a huge amount of fire-crackers. After bursting of crackers, respirable suspended particulate matter (RSPM) and suspended particulate matter (SPM) have been released into the lower part of atmosphere. Apart from these, toxic gases, carbon dioxide, oxides of sulphur and nitrogen have also dissolved in the lower atmosphere. An attempt has been made in the present study, for investigating the effect of the dispersion in lower atmosphere of these gases due to bursting of fire crackers during Deepavali over Faridabad city. For the same purpose, meteorological data and aberrant air quality data of last four years (2014, 2015, 2016 and 2017) have been used in this study. After carefully examination, the present study advocates that the ambient air quality in Faridabad city during Diwali festival changes when compared with non-Diwali days. The study regions have shown the severe air pollution for all four years during Diwali days as compare to the Non-Diwali days.
