Characterization of Factors Affecting the Diffusion Kinetics of Vapor Phase Elemental Mercury through a Soil Column
Elemental mercury has a very high volatility allowing easy dissipation from water or soil into air. To better understand how the kinetics of diffusion of elemental mercury through a medium, which is soil in this study, a mercury diffusion column experiment was done. The correlation between temperature and equilibrium concentrations of mercury in standardized soil samples and a pure mercury standard were determined. Total mercury concentrations were analysed using CVAFS. The effect of time and soil depth to the kinetics of mercury diffusion were determined. Differences in mercury concentrations at different sampling probes were observed during the first few gas phase analyses. Equilibrium was reached through the column after 72 hours.
