Gas-geochemical research

 Microbiological formation of methane is widespread in nature, a process o taking place under reducing conditions at high humidity and content of organic matter. The most intensive processes of microbial production of methane are wetlands in landscapes (bogs, waterlogged soils), termite mounds. The main anthropogenic sources of methane are domestic and industrial waste, sludge filtration fields. Formed methane diffuses into an aerobic zone. Soil and grounds are adsorbing gases by using molecular adsorption processes deposited in the pore space, using the mechanisms of diffusion permeability. The intensity of these processes depends on the moisture content, aeration porosity, total porosity and dispersion of soils. Methane is slightly soluble in the soil and ground moisture. The solubility depends on the temperature parameters. The methane is oxidized by a specific group of microorganisms that make up a bacterial filter. Its operation significantly reduces the concentration of methane in soils and subsoils, and prevents the emission into the atmosphere. In the case of partial oxidation of methane by microorganisms with increasing temperature soils emit methane into the atmosphere. Methane oxidation is accompanied by the released carbon dioxide. The formation of methane in anaerobic conditions, transport it in the aerobic zone, the oxidation of methane specific group of aerobic microorganisms, results in evolution of carbon dioxide, obtained in the natural sciences title Zengen’s cycle. From this perspective, we investigate the adsorbed free dissolved, emission and recycled - oxidized biologically - methane. When geochemical studies are usually taken into account free to soil methane and carbon dioxide.

 Determination of the methane content at a depth of 5 - 10 cm, the emission of methane and carbon dioxide from the soil into the atmosphere is held static chamber method. As cameras use small hollow metal cylindrical vessels open bottom insulator volume of about 1100 cm3, which cut into the surface of the soil to a depth of 5 cm.
