Presented are the results of measuring the concentration of atomic mercury Hg0 on August 28– 30, 2012 in the atmospheric surface layer over the Ussuri Bay in the Sea of Japan during the typhoon Bolaven passage. It is revealed that the Hg0 concentration during this period varied from 1.7 to 3.3 ng/m3. The maximum values were observed at the coming of mercury-enriched air masses from the Yellow Sea area at the simultaneous decrease in the air pressure and increase in the wind speed.
