Assessment of the Impact of Fireworks on Ambient Air Quality
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 4
Abstract
Fireworks are one of the most unusual sources of pollution in atmosphere; although transient, these pollution episodes are responsible for high concentrations of pollutants. The festival of Diwali is celebrated all over India with extensive coordinated fireworks display. The influence of these celebrations on the immediate and long-term air quality and impact on the health and well being of the public needs research. Atmospheric pollutants emitted during fireworks display, have significant effects on human health and environment, on the eve of Diwali festival when extensive fireworks are burnt. The combustion clouds contain harmful fumes and particulate matter released at the surface. Particulate matter is one of the major concerns, with PM10 and PM2.5 being especially hazardous. Existing emission standards impose restrictions on the total mass concentration of emitted particulates, PM10 and PM2.5. This study is focused on the influence of fireworks on the ambient air quality at Dhanbad, India, during Diwali in October 2014. Particulate matter samples are collected during the period of three days, on the day of Diwali and also on the day before and the day after. Elevated concentrations of particulates PM10 and PM2.5 were measured during the intense usage of fireworks. The concentration of PM10 was observed to increase to about four fold over the control days of observation during the period. Moreover, the concentration of PM2.5 increased by 200%. The fireworks activities have been increasing every year and generation of particulates at their increased levels for short duration can potentially cause adverse health impacts on a regional scale in a highly populated region.
