Biogeochemical technologies for remediation and diagnosis of contaminated soils in impacted polar ecosystems are the topic of this chapter. These technologies are based on modeling and management of ecosystem biogeochemical cycles and are aimed at reclamation of these cycles when they are disturbed. The technique for control of purification of soil contaminated with hydrocarbons (oil, gas condensate, and products of their processing) and neutralization of hydrocarbon slurries (sediments) can be carried out by analysis of the activity of two enzymes: catalase and dehydrogenase. In this case, for purification and neutralization, a biological agent containing hydrocarbon-oxidizing microorganisms is used, leading to complete decomposition of the hydrocarbons by catalytic action of the catalase enzyme produced by the microorganisms.
