Abstract

The effect of solution composition on the movement of Hg ions through soils was studied. Three solutions spiked with HgC12 were passed through four different soils. The solutions were 0.25 mM Na2 EDTA, simulated sanitary landfill effluent, and deionized water. The Hg ions were found to be more mobile in the effluent from the simulated landfill than in the other solutions. The formation of mercurous ions and the presence of organic matter seem to be the major contributing factors for Hg; movement through soils in simulated landfill effluent.
