Abstract

The atmospheric geochemistry of mercury is generalls represented by gaseous elemental phase that exhibits the high environmental mobility and relatively long atmospheric residence time (c.a., 1 year) with its high chemical stability. In the recognition of the environmental significance of its global cycling, enormous efforts have been devoted to the measurements of Hg exchange across air-soil boundary. To be able to describe the fundamental aspects on this subject, the current development in the measurements of atmospheric exchange rates of mercury has been summarized using the current database reported worldwide. As a first step, different techniques commonly employed in its measurements are introduced with the discussions on their merits and disadvantages. Then, the results derived from various field measurement campaigns are also compared and discussed. The direction for the future study of mercury is presented at last.
