Abstract
As an intermediate product of the steel production process using an electric arc furnace, electric arc furnace dust (EAF dust) occurs. The resulting intermediate product of steel production is considered hazardous industrial solid waste in many countries of the world, given that it contains a large number of heavy metals that can reach the environment due to the action of atmospheric influences if it is not adequately disposed of. In this paper, the physico-chemical characterization of the EAF dust originating from a steel plant in the Republic of Serbia was performed, and Toxicity Characteristic Leaching Procedure (TCLP test) and Leachability Procedure (LP test) were performed in order to define the impact of this material on the environment and human health. The chemical analysis of the tested sample of the EAF dust showed a zinc content of 32.44%, iron – 18.92%, lead – 1.39%, cadmium – 0.04%, chromium – 0.25% and a lower content of a large number of other elements. The results of the LP test showed an increased chloride content in the leaching eluate, above the permittedlimits, even for waste disposal at a hazardous waste landfill. In the TCLP eluate, the content of zinc, cadmium and lead are above the permitted limits, thus the sample shows toxic characteristics and danger to the environment and human health. In order to environmental and human health protection, it is necessary to do the treatment of this type of material before disposal at the landfill.
