The Contents of Chemical Elements in Mire Ecosystems of the North Altai
Wetland ecosystems perform several functions: hydrological, geomorphological, climatological, etc. They serve as a natural filter, absorbing toxic elements. Therefore, the research contents of chemical elements in peat deposits of bogs and in bog waters is great interest for the ecological status of the territory. The purpose of our research was to study the elemental composition of peat and bog waters of fen (Turochak) and 2 transitional bogs (Kutush and Ynyrga) on the territory of Northern Altai. Turochak bog, an area of 119 hectares, the age of 7060±90, the bog depth of peat deposits up to 6 m and the basal rock by organic-mineral sediments. The peatland of transitional bog Kutush, the age of 2215±140 years, the bog depth of peat deposits up to 2.0 m, an area of 850 hectares and the basal rock by organic-mineral sediments. The transitional bog Ynyrga, an area of 1382hectares, the bog depth of peat deposits up to 2.1, the age of 2265+140 years and the basal rock by clay and loam. Chemical elements were determined by the methods of Inversion voltamperometry and neutron activation. Researches have shown that content of chemical elements in peat bogs is smaller than in soils and the basal rocks of the Altai mountain region. In fens of Altai is concentration of elements in the upper layer of peat deposits (up to 225 cm) and transitional peat deposits significantly increases the contents of almost all chemical elements in the layer near the basal rocks. Thus, peat deposits of bogs and in bog waters of the North Altai are ecological clean.
