The results of mercury and selenium analyses conducted on northern pike (Esox lucius) muscle tissue indicate distinct and significant differences between the mercury and selenium levels of fish from two lakes in Quebec. While fish samples from Lake Dufault had very low mercury concentrations, they appeared to have elevated amounts of selenium. Conversely, fish samples originating from Lake Duparquet had elevated mercury concentrations and low selenium levels. In both cases a comparison of means by the Student t test indicated significant (P < 0.01) differences between the mercury and selenium concentrations of fish samples from the two lakes.
