FACTORS AFFECTING MERCURY BIOMAGNIFICATION IN RIVERINE FOOD WEBS IN THE ROCKY MOUNTAINS: CLARK FORK RIVER BASIN, MONTANA, U.S.A.
A number of studies suggest that Hg biomagnification in aquatic systems are dependent on two factors: a source of mercury and the potential for this mercury to become methylated. To compare the importance of these two factors in a riverine system I examine sites with varying sediment total mercury …

Unifying ecosystem concepts and mercury biomagnification in an estuarine environment using stable isotopes (delta-carbon-13 and delta nitrogen-15).
… between food web structure and patterns of mercury biomagnification. On a delta13C and delta15N basis, three different sources of energy were identified: terrestrial carbon, in situ estuarine primary production, and marine phytoplankton. Isotopically depleted delta13C and delta15N values …

An investigation of the factors affecting mercury accumulation in lake trout, Salvelinus namaycush, in northern Canada
… the variables that most explain the elevated mercury concentrations in lake trout (Salvelinus namaycush), a predatory aquatic fish species in some lakes in northwestern Canada. High mercury concentrations in lake trout in other regions have been associated with the biological features of the …
