Glacier and glacier-fed runoff were intensively sampled and analyzed for mercury speciation. Particulate Hg is the predominant form of Hg in glacier and river water. Total Hg concentration in the glacier-fed river showed clear diurnal variation. Qugaqie Basin has a small Hg export yet remarkably high Hg yield compared with other glacierized basins globally. Alpine glaciers will exert increasing impacts on Hg transport under the changing climate.
