Abstract
This article focuses on studying biotechnologies for remediation of soils contaminated with heavy metals to determine further the most effective methods for cleaning soils from the action of toxicants with their subsequent implementation in practice. The soil restoration methods were analyzed, their advantages and disadvantages were identified, making it possible to establish that biological methods are the safest and most environmentally friendly. The expediency of using biological methods lies in the possibility of breeding strains of microorganisms that destroy soil toxicants. However, the efficiency of microbial cultures is not equally high due to a narrow range of favorable conditions for functioning, the risk of manifestation of the phenomenon of degeneration of microorganisms until the required level of soil purification is achieved. This confirms the prospects for the further development of this direction and the search for ways to eliminate certain disadvantages of biological methods. For an integrated biotechnological solution to soil remediation, a scheme of aerobic plants was developed, which is characterized by two stages: aerobic soil cultivation with biocomposite and a phytoremediation stage for additional purification and control of the content of toxicants in the soil.
