Biomagnification of Monomethylmercury in Carnegie Lake x 10 4 H2OH2O

Are there differences in MMHg uptake for different species of phytoplankton? Which characteristics might be related to increased uptake?

Size Fractioning Target GroupFilter pore size Phytoplankton and particulates0.4−20 μm Herbivorous zooplankton>20 μm Target GroupSignal Live AutotrophsDNA & chlorophyll Live HeterotrophsDNA DetritusNone Flow Cytometry

Within each site: Does the concentration of MMHg increase with increasing trophic level? ClamsAmphipodsBlood wormsSnails

Comparing the 5 sites: Is there a correlation between the density of phytoplankton and the concentration of mercury in the biota? Phytoplankton density based on fluorescence of chlorophyll (mg of chlorophyll L -1 )

High Plankton Densities Reduce Mercury Biomagnification Chen & Folt, 2005

Question: Is there a correlation between the density of phytoplankton and the concentration of MMHg in the biota?
