Industrial and technological progress negatively affects the environment by polluting and degrading the soil. One such industry is sponge iron industry where sponge iron is made from reduction of iron in presence of coal as input material and is used as a raw material in making steel. The coal FA emitted from furnace of coal based sponge iron industry contains heavy metals like arsenic, cadmium, cobalt, copper, chromium, nickel, lead, zinc and mercury.Thus, deposition of FA in the surrounding environment of sponge iron plants leads to accumulation of heavy metals in the soil. The aim of the present investigation is to understand and get aware with the pollution, mainly heavy metal pollution of the study area (in and around the integrated coal based Bhushan sponge iron plant present at Rengali block of Samblpur district as experimental site and a nonindustrial site 28.1 km away from the experimental site as control) and the effect of the sponge iron industry waste particularly the bottom fly ash (FA). All the studied heavy metal concentrations were predominantly elevated in the soil samples of experimental site as compared to the control site indicating the negative influence of sponge iron plant and the soil pollution due to heavy metals present in it
