Abstract:
A study was carried out to determine the concentration of heavy metals like cadmium, Copper, Nickel, Zinc, Lead, Manganese and Iron present in ambient air of capital city of Odisha, Bhubaneswar. Simultaneously particulate matter like PM10 and PM2.5 and gaseous pollutants like SO2, NOx, O3, and NH3 were also monitored on seasonal basis while heavy metals were collected once a year. The obtained results were reflected and compared with the Ambient Air Quality standards prescribed by the Minister of Environment and Forest (MoEF). The concentration of lead at all locations was found to be within the limits i.e. 0.5 µg/m3. Similarly nickel concentration was also detected below the limit i.e. 20 µg/m3. In the ambient air of Bhubaneswar heavy metals like cd is in the range of 0.0036-0.0084, Cu-0.0079-0.0136, Ni-0.0173-0.02554, Zn-0.1213-0.1641, Pb-0.1259-0.2492, Mn-0.10058-0.145, Fe-1.2767-1.7158. From the study it was found that the concentration of heavy metals in the ambient air is low except iron. The seasonal range and annual average of particulate matter as well as gaseous pollutants of all the locations were calculated and compared with the Ambient Air Quality Standards (NAAQMS, 2005).
