I am interested in finding scientific information related to the biology of
mercury levels in lakes.
Inland lakes are void of visible life outside of weedlines, with a few
exceptions...one being microorganisms. Knowing one way in which mercury
enters the food chain is through these microorganisms, how much effect would
there be if we introduced large amounts of decaying woody debris?
We live in an area where logging was done a hundred years or more ago. Left
behind in the lakes where the logs were floated for eventual processing, are
dead heads lying in relatively deep water and beginning to decay. It seems
to me that by leaving these logs in the depths of the lakes, we are aiding
the accerleration of mercury entering our food chain. If, in a normal void
area of a lake there were x amount of microorganisms, wouldn't the addition
of this wood would raise those levels to an unnatural state and be somewhat
like pumping mercury into our food chain?
