Heavy Metals in the Atmospheric Precipitation on the Barents Sea Coast

摘要

The results of heavy metal measurements in monthly precipitation samples are analyzed at biological station Dal'nie Zelentsy to define the role of the atmospheric precipitation in the marine environment pollution in the Barents Sea coastal region. Peculiarities of the atmospheric processes and the genesis of air masses bringing the precipitation and the extent of their effect on the precipitation pollution with heavy metals are considered based on the data obtained in 2001-2002. Of the air masses brining the precipitation to the Kola Peninsula coast the air masses of a marine origin have significant advantage. It is shown that weight average heavy metal (except copper) concentrations in the precipitation from the marine air masses on the Kola coast are higher than in the precipitation from the continental air masses. The emissions from local metallurgic enterprises influence the extent of the precipitation pollution with copper.
