ТЯЖЕЛЫЕ МЕТАЛЛЫ В КУСТИСТЫХ ЛИШАЙНИКАХ КАК ИНДИКАТОР АТМОСФЕРНОГО ПЕРЕНОСА ЗАГРЯЗНЯЮЩИХ ВЕЩЕСТВ В АНТАРКТИДЕ

The content of a number of metals in some fruticose lichens from East Antarctica has been studied. The influence of various sources on the formation of their composition has been estimated. It has been shown that long-distance atmospheric transfer of such elements as Zn, Mn, Cu, Pb, Ti, Sr, Rb, Y, Ba has an essential impact on their accumulation in lichens. Accumulation of aluminium and iron in lichens is associated with their lithogenic origin. Comparing to other lichens, Pseudephebe pubescens is characterized by a significant accumulation of the above-noted metals, and this species can therefore be used as an indicator of atmospheric transfer of pollutants in the air.
