“…Many researchers have observed elevated mercury concentrations in different species of fish (Brazner and DeVita, 1998;Dellinger, 2004;Fox et al, 2002;Gerstenberger and Dellinger, 2002;Koster et al, 1996;Scheider et al, 1998;Weis, 2004) including invasive fish species (MacEachen et al, 2000) in the Great Lakes. In addition, there are numerous reports of mercury contamination in the waters (Mason and Sullivan, 1997;Rolfhus et al, 2003;Thompson-Roberts et al, 1999), sediments (Marvin et al, 2002;Marvin et al, 2003;Marvin et al, 2004;Painter et al, 2001;Richman and Dreier, 2001;Rolfhus et al, 2003;Rossmann, 2002;Rossmann and Edgington, 2000) and biota other than fish (Bishop et al, 1995;Cleckner et al, 2003;Francis et al, 1998) of the Great Lakes-St. Lawrence River basin.…”
