An individual-based model was applied to the 1986 population of Lake Ontario lake trout to estimate the PCB concentration in alewife prior to 1986 and to determine the amount of variability in PCB concentrations of lake trout prey. Results suggested that spatial variability in the PCB concentrations of lake trout prey was probably greater in Lake Ontario than in Lake Michigan.
