Atmospheric losses in the middle ob river basin and their influence on a hydrochemical runoff of the rivers

Generalization of results of researches and date of other authors about losses of chemical substances from an atmosphere in the Middle Ob river basin from 1967 to 2007 years is executed. The estimation of average long-term receipts of chemical substances from an atmosphere on drainage basin is received: the main ions - more than 1400 thousand ton/year, carbon of organic substances - more than 490 thousand ton/year. More than 60-70% of atmospheric losses drop out in a warm season. Atmospheric losses form about 37% of an ionic runoff of the Middle Ob river and about 16% of a runoff of carbon of organic substances.
