Abstract:
The using of biosolid and of supported tuff for decreasing metals availability from soil polluted with waste mining was tested in this paper, by using of two grass plants, Medicago sativa and Festuca arundinaceea. In case of Festuca arundinacea, the decreasing of Zn and Mn accumulation in plant tissues took place about 1.8 - 2.3 times, and 3.5 - 5.0 respectively; Cu and Pb concentrations decreased 2.6 - 3.2 times and 7.6 - 10.7, respectively. Similar results were obtained for Medicago sativa. It was determined that using of biosoild and supported tuff, allowed important immobilization of metals in polluted soils.
