| Abstract |
The goal of this study was to conduct a screening level probabilistic ecological risk assessment for copper and cadmium in the Chesapeake Bay watershed by using problem formulation, analysis, and risk characterization. This probabilistic ecological risk assessment characterized risk by comparing the probability distributions of environmental exposure concentrations with the probability distributions of species response data determined from laboratory studies. The overlap of these distributions was a measure of risk to aquatic life. Comparative risk from copper and cadmium exposure was determined for various basins in the Chesapeake Bay watershed. |
