Deposition of Metals from the Atmosphere at the North Pole Compared to Background Regions of the Northwestern USSR

An intercomparison of dry and wet deposition of heavy metals and a number of trace elements has been made on the basis of the analysis of snow samples for Ladoga and Onega lakes as well as for the central Arctic. A comparative assessment of contributions to lake pollution (Great Lakes included) due to atmospheric deposition and river runoff has been given. Annual variations in the deposition of heavy metals due to the varying air transport and industrial emissions have been analyzed.
