elevated mercury concentrations in fish in lakes in the mackenzie river basin: the role of physical, chemical, and biological factors.	during the mid-1990s and through the early 2000s, researchers determined that elevated mercury concentrations were a common occurrence in predatory fish in many lakes in the mackenzie river basin (mrb), located in northern canada. here we present the results of studies investigating factors contributing to higher mercury concentrations in fish in many of these lakes. twenty-two percent of lake trout, 33% of northern pike, and 50% of walleye populations had mean mercury concentrations >0.5 microg ...	2005	16183101
investigations of mercury concentrations in walleye and other fish in the athabasca river ecosystem with increasing oil sands developments.	recent studies have reported an increasing trend of mercury concentrations in walleye (sander vitreus) from the athabasca river, north eastern alberta (canada); these studies were based on three years of comparison and attributed the mercury increase to expanding oil sands developments in the region. in order to conduct a more comprehensive analysis of mercury trends in fish, we compiled an extensive database for walleye, lake whitefish (coregonus clupeaformis), northern pike (esox lucius) and l ...	2012	22652822
