Abstract
The chemical composition of atmospheric precipitation over the entire territory of Karelia is characterized on the basis of snow samples taken during the periods of maximum snow storage in 1996–2000. The concentration of chemical elements and their fallouts are considered within the northern, central, southern, and eastern regions of Karelia. The aero-technogenic effect of industrial centers of Karelia and the Archangelsk Province on the chemical composition of atmospheric precipitation is analyzed. The above material is generalized in the form of average statistical characteristics of the chemical fallouts of mineral, organic, and biogenic substances, heavy metals, and strong acids.
