Micrometeorological gradient approach for quantifying air surface exchange of mercury vapor: tests over contaminated soils

Article Abstract:

Fluxes of elemental mercury vapor (Hg(super 0)) over the forested flood plain of East Fork Poplar Creek in Oak Ridge, TN, were measured using the micrometeorological modified Bowen ratio method during the spring and fall of 1993. Results revealed that significant amounts of Hg(super 0) were constantly released by the contaminatd soils into the atmosphere. Fluxes, which increased in an exponential fashion in relation to soil temperature, seemed to be regulated by contaminant elemental Hg volatilization and the reduction of Hg(super 2+) to Hg(super 0).
