Abstract

The accumulation and species of mercury Hg in mosses and lichens collected from highaltitude Tibetan Plateau were studied The altitudes of the sampling sites spanned from 1983 to 5147 m and a total of 130 mosses and 52 lichens were analyzed The total mercury THg contents in mosses and lichens were in the ranges of 131–2730 and 202–3459 ng/g respectively The average ratios of methylmercury MeHg in THg in mosses and lichens were 24  03–111  and 27  04–96  respectively which were higher than those values reported in other regions The contents of THg in both mosses and lichens were not correlated with the THg in soils p  005 The lipid contents displayed a significantly positive correlation with concentrations of MeHg in mosses r = 0461 p  001 n = 90 but not in lichens The correlations between Hg contents in mosses and the altitudes latitudes and longitudes of sampling sites indicated the mountain trapping and spatial deposition of Hg in the Tibetan Plateau
