Abstract In this study, Hg and its speciation in snow, ice and streamflow in three typical tibetan marine glaciers were investigated to understand the controlling factors during Hg transport processes. Results show that THg (total Hg) concentrations of snow and ice samples in Gongga Glacier were slightly higher than the values of global background, while values in Mingyong Glacier and Midui Glacier were at the global background levels. The average THg concentrations of all snow, ice and water samples of three glaciers were (4.78±5.99) ng/L, (1.72±1.15) ng/L, (1.31±0.91) ng/L, respectively. The variation of THg concentration was in snow > in ice > in water. Such trend was mainly controlled by the processes of sedimentation of particulate Hg and the volatilization of gaseous elemental Hg. The THg concentration in the streamflow of Gongga was the highest in June (7.48±2.22) ng/L and the lowest in November (1.39 ±0.27) ng/L. The HgP was significantly correlated to the THg, and HgP/THg was the highest in snow, followed by ice, and the lowest in streamflow. The variation of HgP/THg and monthly average THg output in the streamflow of Gongga Mountain were controlled by streamflow and rainfall intensities. Principal component analysis further indicates that the THg concentration in snow and ice was mainly affected by atmospheric particulate deposition and monsoon transport. Compared with the other two glaciers, Gongga Glacier was more susceptible to influence by human activities because of much closer to the intensive populated areas.
