- Abstract
This article analyzes the role of microbiological processes in the formation of geochemical barriers and redox zones in the contamination of soils and aquifers with metals. A significant contribution to environmental contamination is made by heavy metals in waste storage sites, as well as by their migration with the resulting leachate to the aeration zone and ground water. Special attention is paid to the characteristics of the behavior of heavy metals in changing redox conditions, as well as their transformation and entry into aquifers. Mechanisms of biological transformation of metals to reduce their toxic impact on the environment are considered. It is noted that the biological detoxification of the natural environment is a combination of processes of metabolism and bioconcentration as a result of complex formation, sorption, and biodegradation of the substance, depending on the biological activity of the environment and nature of contaminants. The bioremediation of contaminated areas and aquifers is one of the safest, cost-effective, and environmentally friendly technologies for the detoxification of contaminated sites of territories and aquifers.
