Abstract
The report documents an initial testing and sensitivity analysis of the Terrestrial Ecosystem Exposure Assessment Model (TEEAM). TEEAM calculates the exposure concentrations of contaminants in plants and animals in terrestrial ecosystems. The project was performed in two phases. First, a sensitivity analysis was performed using a simple system--an American robin inhabiting a typical peanut field in Georgia that had been treated with diazinon. The primary food source for the robin was the earth-worms living in the pesticide-contaminated soil. Second, an intensive model testing and evaluation effort was undertaken to examine each major model component. Results of the testing suggest that continued model development should focus on better simulation of surface ponding, plant transport, and uptake by soil dweller and above ground insect populations.
