ABSTRACT
Hydro-chemical conditions of the Marsh Rivers, lakes and streams in the oil-and-gas marshy territory of the Arctic zone of Western Siberia are investigated by us. The article presents the hydro-chemical characteristics of marshy rivers, which are taking runoff from the territory of oil-and-gas deposits (Urengoyskoye, Komsomolskoye, Medvezhye, Muravlenkovskoye).
On the base of water balance approach the runoff of the dissolved substances from marsh landscapes is calculated.
The distinction between values of mineral salts and organic substances runoff is discovered. It is shown that mineral salts (ionic runoff) is almost completely are taken out by the river flow from the territory of oil-and-gas deposits. Organic substances of natural origin (humus acids) and anthropogenic origin (petroleum hydrocarbons) are accumulated by peat deposits. Changing the chemicals runoff of the oil-and-gas developed deposits is found. Due to the mining of oil and gas peat deposits the maximum values of petroleum hydrocarbons runoff (>200kg/km2) is estimated, which is rather higher than the background values.
