Characterization of PM sub(10) in the ambient air during Deepawali festival of Rajnandgaon district, India

Deepawali is one of the main festivals for Hindu religion which falls in the period October-November every year with great fireworks display. In this study, we investigated the levels of water soluble ions and heavy metals-during the fireworks festival in Rajnandgaon, Central India. The chemical compositions and noise level distributions are reported from the sampling site. First time during Deepawali, air quality was studied in this area, The Aerosol samples of PM sub(10) (particle aerodynamic diameter Zn > Pb > Ni > Cr > Cd. The result revels that all concentration are above the permissible limit fixed by CPCB, USPEA, and WHO standard. It is concluded that the burning of fireworks during Deepawali festival was the main source of heavy metals and ion.
