Abstract The goal of the study was to conduct a probabilistic ecological risk assessment for tributylin (TBT) in estuarine areas of the Chesapeake Bay watershed by using the following distinct phases: problem formulation, analysis and risk characterization. This probabilistic ecological risk assessment characterized risk by comparing the probability distributions of environmental saltwater 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 TBT exposure was determined for various basins (tributaries) in the Chesapeake Bay watershed. Tributylin saltwater exposure data from the Chesapeake Bay watershed were available from over 3,600 water column samples from 41 stations in nine basins from 1985 through 1996. Most of the stations were located in the Virginia waters of Chesapeake Bay, primarily the James, Elizabeth and York Rivers. In Maryland waters of the Bay, various marina, harbor and river systems were also sampled.
