Regional characteristic of the chemical composition of bog waters in Tomsk oblast

The analysis of regional features of bog waters chemical composition depending on geomorphological conditions of their bedding is carried out. It is noted that the inundated low-lying bogs fed by underground and flood waters, have the greatest mineralization of waters, are characterized by high concentration of iron while waters of terrace low-lying bogs possess the smaller sum of ions, however are more enriched with organic matters, humic and fulvic acids. Waters of terrace transitional bogs differs by smaller content of mineral substances at increase in ion concentration of ammonium and dissolved carbon dioxide. Waters of water partite riding bogs contain the minimum quantity of mineral substances comparable to the contents in atmospheric precipitation, and the maximal ion concentrations of ammonium. The carried-out analysis of change the bogs waters composition depending on geomorphological conditions of bogs massifs bedding allowed to allocate 3 areas which are characterized by particular distinctions in chemical composition of waters within the studied territory.
