Abstract:
The critical analysis of known technologies for soil restoration, contaminated by heavy metals and radionuclides remains relevant Object of work: to systematize (taking into account the possible consequences to biosphere) the known technologies for ecological restoration of soils contaminated by heavy metals and radionuclides one possible methodology for solving any soil problem should be recognized only as a healing technology. For soils contaminated by heavy metals and radionuclides healing patterns is ordered conceptually into the following levels: mission, strategy, technology. The mission of healthy soil should be aimed at maintaining the chemical elements content within the optimum interval. The strategy of healthy soil involves the regulation of individual elements content in the soil. Ex-situ a soil healing technologies is implemented outside the original pollution site. In-situ, a soil healing technologies is carried out directly on the original pollution site. Excavation of the contaminated soil layer is the first stage for ex-situ soil restoration. In the future it will be possible: 1) storage of contaminated soil at special landfills, 2) treatment of contaminated soil at a special reactor. All technologies for in-situ healthy of heavy metals contaminated soils can be ordered as: 1) localization, 2) deconcentration, 3) inactivation, 4) extraction.
