A Windows based computer simulation model of the environmental fate, food-chain bioaccumulation, toxicity and ecological and human health risks of contaminants is presented. Case studies demonstrating the models application in a lake, a river and a marine fjord are discussed and results are presented illustrating the ability of the model to estimate environmental concentrations over time based on chemical loadings. The case studies involve (1) the temporal response of PCB and mirex concentrations in water, sediments, benthos, fish and bird species of Lake Ontario, (2) the time response of concentrations of chlorinated dioxins and furans in sediments and fish in the Fraser River to reductions in pulp and paper mill discharges and (3) the fate and bioaccumulation of chlorinated dioxins and PAHs in Vancouver Harbour. The purpose of the studies and the model is to assess the capability to predict the environmental fate and bioaccumulation on an ecosystem level, which is of importance for developing site specific environmental quality criteria and to assess the ecosystem`s assimilative capacity by relating whole ecosystem loading allocations to environmental quality criteria.
