The iron and steel industry is a crucial corner stone of growth, socio-economic advancement, technological development and overall industrialization of any nation. Among its economic impact is the supply of basic raw materials and products to multitude of industries such as building, construction, machinery, equipment, automobile manufacturing and railways. Metallurgical operations in the iron and steel industry involve series of complex processes, in which iron ore or metallic element is transformed into products. The most vital conversion operation is the extraction process, which involves the reduction of iron ore (haematite/magnetite) to obtain pig iron, by the addition of coke, limestone and other materials in the blast furnace. Other metallurgical operations include smelting, refining, steel rolling and casting. These activities have been reported to be point sources of heavy metals release, with potential capacity for heavy metal pollution. For instance, the conversion of iron ore to molten iron produces significant amount of particulate emissions and carbon monoxide. Considerable quantities of metal laden solid wastes i.e. slag; wastewater and air emissions may also be Investigation of Selected Heavy Metals Level in Top Soils Around Ajaokuta Steel Company, North Central Nigeria
