About the Use of Geochemical Barriers to Prevent the Migration of Mercury Vapor

Keywords: gas migration of mercury, mercury sulfide, metacyanobarite, geochemical barriers, mercury-containing waste
Pages: 843-850


Problems concerning the migration of mercury vapor through different types of organomineral filters are considered, the absorbing capacities of the formed geochemical barriers are determined. The most promising types of geochemical barriers for the subsurface burial in the forest-steppe landscape zone are revealed. An approach to a decrease in mercury vapor evaporation by transforming into a more conservative phase of metacyanobarite modification of mercury sulfide (HgS) is proposed.
