Abstract

The literature suggests that acid deposition may lead to increased mercury (Hg) contamination of fish. Employing published empirical relationships, we have estimated the change in associated Hg contamination with an increase in sulphate deposition from 0.25 to 1.25 g sulfur/m(2)/year. In seepage lakes, one can predict that Hp in walleye from theselakes, and subsequent human exposure due to consumption of these fish, would be elevated at the higher rate of sulphate deposition. However, for drainage lakes, increasing acidic deposition was predicted to reduce Hg accumulation in lake trout and northern pike. Subsequent humanexposure to Hg due to consumption of these species from drainage lakes was therefore also predicted to be lower at the higher rate of acidic deposition. We concluded that the hypothesis that acidic deposition increases mercury (Hg) contamination in fish, and thereby mercury exposure in humans via fish consumption, is only true for acidic deposition onto seepage lakes.
