Abstrakt: Our project is aimed at improving a brownfield in the city of Kladno where an old steel producing facility was in operation. Ecological risk is caused mainly by processing of co-products of coal production (tars, oils). Knowledge of toxicology and environmental aspects will help enhance the protection of human health and the environment. Primarily, we focused on soil sampling and identification of pollutants. Next, we made a selection of suitable plant species for stabilization/decontamination of the site. Plant species were selected based on their resistance to contaminants. First, an effect on seed germination and root growth was tested. Second, a test of cell viability was used. Finally, the concentrations of pollutants on biomass production, pigment analysis, and root morphology were detected. Results showed that organic contamination on site is high. Average concentration of C10-C40 in soil was almost 13 g/kg DW, which is more than the maximum allowable concentration. The germination test proved the soil toxicity. Poplar trees grown on Poldi soil in greenhouse showed the resistance to toxicity of PAH, and their ability of accumulation of PAH from soil was obvious. However, more studies are needed to decide if the poplars are usable for phytoremediation of the brownfield.
