Description
Summary: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. Исследовано содержание ряда металлов в некоторых кустистых лишайниках Восточной Антарктиды. Дана оценка влияния различных источников на формирование их элементного состава. Показано, что дальний атмосферный перенос таких элементов, как Zn, Mn, Cu, Pb, Ti, Sr, Rb, Y, Ва оказывает существенное влияние на их накопление в лишайниках. Накопление лишайниками алюминия и железа связано с их литогенным происхождением. В сравнении с другими лишайниками для Pseudephebe pubescens характерно значительное накопление указанных элементов, и следовательно, этот вид может быть использован в качестве индикатора атмосферного переноса загрязняющих веществ в атмосфере.
