Large quantities of fireworks are used during this festival. The use of fireworks during festive celebrations can cause acute short term air pollution because fireworks contain chemicals such as potassium nitrates, potassium chlorate, potassium perchlorate, charcoal, sulfur, manganese, sodium oxalate, aluminum and iron dust powder, strontium nitrate, and barium nitrate, etc. These firecrackers when burnt can release various gaseous and particulate air pollutants and toxic metals to significant quantity and degrades the air quality as a whole. Concentration of air pollutants particulate viz.

The concentration of particulate pollutants was recorded many times higher because after explosion dust removed from the settled place. The result indicated the huge contribution of fireworks on the pollutant levels. Concentrations of metals like Ba, Cu, Cd, Pb, Hg, Al was observed and these value were higher on Deepawali period compared to the previous day. The probable health impact of this huge though short-lived pollutants deteriorate the ambient air quality and increase in relative health risk in exposed individuals. </span><span style=\"font-size: 12.0pt; line-height: 115%; font-family: \'Times New Roman\',\'serif\';\">Findings of particulate matter indicate that people with asthma or other respiratory disease are the group most at risk.<span style=\"color: black;\"> This paper suggests some controls on fireworks during festive celebrations.</span></span></p>
