Since the term abandoned hazardous sites was first coined in the 1978 environmental report of the Council of Environmental Specialists, a number of different types of technology has been developed in the Federal Republic of Germany for the remediation of contaminated soils. At former sites of the mining industry, such as metallurgical and coking plants whose soil has been contaminated by organic and inorganic pollutants over decades of industrial activity, there is an necessity for soil remediation. Also, many former locations of metal processing works, battery factories of scrap yards have been contaminated in particular by heavy metals. Wet mechanical soil decontamination has proven successful over the past 10--15 years in the purification of these soils. The subject of this presentation is to consider how soil decontamination processes can be effectively improved through a description of the material properties of soils contaminated by heavy metals, and through carrying out basic investigations about the adsorption of heavy metals. Soils of different origins, especially those from former mining and metallurgical sites, were used for the experiments.
