HEAVY METAL UPTAKE BY PLANTS IN DIFFERENT PHYTOREMEDIATION TREATMENTS

The goal of our research was to develop the phytoremediation technology by testing different treatments under field conditions. The experiment was based on the integrated improvement of physical, chemical and biological conditions of Gyöngyösoroszi spoil. 18 different phytoremediation treatments were tested. The highest chemical risk of Gyöngyösoroszi mine waste was found in case of Pb, Zn, Cd and As. The plots could be successfully vegetated. The biomass production of different treatments was largely different. Multi-level revitalization not only had high impact on the biomass production, but also reduced the heavy metal uptake of plants. The concept of the integrated phytoremediation technology proved to be an efficient tool to stabilize the surface of spoils by plants.
