| Abstract: | Outflow of chemical substances from the catchment area of the Karelian drainage network is discussed using hydrochemical data obtained in more than 80 rivers of Karelia over the period of many years. Weighted average characteristics of river water composition were found for ten large basins and for the entire region. Specific outflow was defined and its value was compared with atmospheric chemical precipitation; the difference made it possible to reveal the real input of chemicals from the catchment areas of Karelia. |
