• The performances of assessment models for estimating the transfer and bioaccumulation of mercury in a lake ecosystem were tested by being applied to a test scenario proposed in an international cooperative study named BIOMOVS. Two kinds of models have been developed to estimate mercury concentration in fish. One uses a bioaccumulation factor approach which is applied to an ecosystem in equilibrium, whereas the other is a dynamic model in which both the change of the concentration in water and the metabolism in fish are taken into account. For this scenario, the former was not adequate but the latter could predict more accurately because the concentrations were not in equilibrium. The limitations of applications were suggested for the two models employed here. It would be important in the present case to take into account that equilibrium was not attained in the ecosystem and the metabolism of mercury in the fish was very slow.
