Objective:
The objective of this research project is to develop the Unit World Model (UWM) for metals. As a replacement for the current methods for evaluating the effect of metals in the environment, the Center is developing a model for the behavior of metal compounds that can be used as a tool in the hazard assessment of metals and metal compounds. This model will include the physical and chemical mechanisms that control the fate and resulting bioavailability of metals discharged to natural waters. In particular, the transformations that affect metal fate and toxicity will be included.
Progress Summary:
The initial focus of this research project is on the development of a metals model for lakes. For this purpose, a coupled water column/sediment flux model is being developed in Microsoft Visual Basic for Microsoft Excel. The code to track the cycling of organic carbon, nutrients, oxygen, and redox-sensitive species (S, Fe) between the water column and sediments has been developed, and the computer code is being tested.Future Activities:
We will continue efforts to develop the UWM. The next step will be to add the metals overlay to the model. The model then will be used to perform a more detailed evaluation of available data for lakes.References:
