Air Quality Impact of Sponge Iron Industries in Central India


Emission load of particulate matter from 42 sponge iron industrial units located in clusters in the Indian State of Chhattisgarh was estimated to be 1,361 TPD. US EPA air pollution dispersion model ISCST-3 applied to predict the impact of the sponge iron industry emissions on ambient air quality showed contribution up to 546 μg/m3 to the surrounding air basin causing the air quality exceeding the national ambient air quality standards. Electrostatic precipitator (ESP) has been suggested to all the above industrial units that would bring down the contribution to as low as 27 μg/m3.
