The Dynamic Ofecological Conditions and Accumulation of Chemical Elements in Genesis of Watershed Mires of Central Russia

The article shows the dynamic of ecological conditions during development of watershed mires of karst origin. The genesis of mires depends on state of surrounding landscapes, types of bedrocks and hydrology. All these features lead to differences in accumulation of chemical elements in peat deposits. For each element the natural background was defined. The exceedances of natural background indicate anthropogenic impact. By this way, ecological situation of the region was defined.
