Abstract:

The 25-year line of data concerning air mass transport to three points in the Russian Arctic has been extended till 2010 and analyzed. The atmospheric transport of aerosol anthropogenic impurities to the Russian Arctic has been studied with its spatial, seasonal and long-term features. Changes in atmospheric circulation through 25 years (1986–2010) lead to the increase of the share of marine air masses over the northern islands of Eurasia. It can have effect on compositions of soils, river and lake waters, as well as living conditions of the Arctic flora and fauna. For the last decade (2001–2010) the average anthropogenic air concentrations of heavy metals (Pb, Cd, As, Zn, Ni, Cr, Cu) and soot, as well as their average fluxes onto the surface were estimated in the regions of Franz Josef Land and Severnaya Zemlya archipelagos. The results of the work can be used to study long-term varying processes and parameters of different land and marine objects and ecosystems in the Russian Arctic under anthropogenic influence.
