ABSTRACT- The paper reports the development and testing of a computer simulation model of the fate of contaminant discharges in Burrard Inlet. Contaminants are introduced into Burrard Inlet by a number of sources including both, (e.g., industrial and municipal effluent discharges) and such as storm water runoff. Once introduced to the inlet, contaminants are subject to physical, chemical and biological processes that lead to dispersion and accumulation in different matrices of the marine environment. The main purpose of the model is to provide a comprehensive ecosystem-level assessment of the fate of contaminants in aquatic and terrestrial ecosystems with a focus on the relationship between chemical emissions and resulting concentrations in biota as a function of observed elevated concentrations of Persistent Organic Pollutants (POPs) in sediments. The results of the study include recommendations for the development of sediment target levels and loading for PCBs and PBDEs, facilitating more defensible management decisions regarding future measurements concentrations of POPs in Burrard Inlet
