Abstract
In India, festivals are celebrated with lot of enthusiasm and Diwali is the major festival of light. In this festival, houses are illuminated by lights and sky is illuminated by fireworks. These fireworks though create lot of amusement but also pollute the atmosphere in terms of air pollution. The continuous air pollution monitoring was undertaken during Diwali festival (2014) at residential site NEERI, Nagpur. Air quality parameters were compared with CPCB standard. On Diwali day, PM10 and PM2.5 concentration achieve its highest value of 900 μg/m3 and 950 respectively μg/m3. This high concentration is maintained in atmosphere for two days of this festival in atmosphere which is approximately 8 - 9 times more than that regulatory standard. These particles carry all the components of the cracker including heavy metals, alkali metals, alkaline earth and change the atmosphere with positive and negative ions apart from impaction of sulfur and other acid gases to the atmosphere.

Summary
Diwali festival is celebrated in winter season around October, November every year. Due to atmospheric inversion & cold climate, the air pollution load is very high as the pollution load is very high and the pollutants tend to settle down due to low dispersion & dilution in the atmosphere. During Diwali festival time, it attains episodic high level in the air quality. (2016) Real Time Ambient Air Quality Status during Diwali Festival in Central, India. The city celebrates Diwali festival in which various types of crackers are burst, which generates lot of air pollution in atmosphere. This may cause episodic rise in PM10 and PM2.5 in atmosphere and imparts adverse effect on regional visibility, global climate change and health [1]. The CAAMS (Continuous Ambient Air Quality Monitoring System) was installed in the residential area and real time monitor 13th October to 28th October 2014 at NEERI Nehru Marg residential site (Environment S.A.)
