| Project Summary | |
| The objective of this proposal is to develop general models of metal speciation/partitioning and fate that can be used to kink metal emissions with bioavailable concentrations that result in metal exposure to biota. Improved metal complexation constants for soils has begun with extraction of humic and fulvic acid fractions from soils; additionally, two synthetic minerals (goethite and birnessite) have been prepared. Aqueous speciation and surface complexation models, originally written in QuickBasic, are being converted to Visual Basic. Mass balance models of metals' fate in lakes and rivers are also being converted to Visual Basic, so that the two models can be combined and tested on Ross Lake. A joint research project has been initiated between the investigators and Hudson Bay Mining and Smelting for water and sediment data collection ; these data will be used to test the combined aqueous speciation-surface speciation/mass balance models for Ross Lake. | |
