Cr is one of the heavy metal contained in EAF steel slag and its presence may be due to the use of scrap metal with high Cr content in the EAF during steelmaking. Cr exists in the most stable form as Cr (III) and (VI) in the environment. Cr (III) is an essential element in human metabolism at low dose, relatively immobile and low in reactivity [5].
