  • Effects of experimental thermocline and oxycline deepening on methylmercury bioaccumulation in a Canadian Shield lake 

    Perron, Tania; Chételat, John; Gunn, John; Beisner, Beatrix; Amyot, Marc (American Chemical Society, 2014-02-10)
    Environmental disturbances like deforestation or climate change may influence lake thermal and oxic stratification, thereby modifying cycles of contaminants such as mercury (Hg). In a lake naturally separated into three basins, the thermocline and ...

  • Environmental drivers of rare earth element bioaccumulation in freshwater zooplankton 

    MacMillan, Gwyneth A.; Clayden, Meredith G.; Chételat, John; Richardson, Murray C.; Ponton, Dominic; Perron, Tania; Amyot, Marc (American Chemical Society, 2018-12-26)
    Human activities have resulted in significant release of rare earth elements (REEs) into the environment. However, the pathways of REEs from waters and soils into freshwater food webs remain poorly understood. Recent studies suggest that aquatic ...

  • Fate and trophic transfer of rare earth elements in temperate lake food webs 

    Amyot, Marc; Clayden, Meredith G.; MacMillan, Gwyneth A.; Perron, Tania; Arscott-Gauvin, Alexandre (2017-05-05)
    Many mining projects targeting rare earth elements (REE) are in development in North America, but the background concentrations and trophic transfer of these elements in natural environments have not been well characterized. We sampled abiotic and food ...
