The content of mercury in uneven-age needles of different trees from sites “Mondy”, “Arshan”, and “Tunka", Republic of Buryatia, is studied. Original data on mercury accumulation level and features of its distribution depending on conifer type, age of needles, landscape, and climatic conditions are presented. The Hg concentrations in needles estimated for the territory of Eastern Siberia do not exceed the literature data and are within the limits of average concentrations for Siberia and Russia in general.
