According to something I read (so this is hearsay) one gram of Hg will
be enough to raise the pollution level in an average 28 ac. lake to over
the acceptable limit. We're talking ppb.
What I did with the stuff as a kid makes me cringe.

Liquid mercury is relatively insoluble and lies at the bottom of the
waterway(usually downstream from a paper pulp plant) until bacteria
convert it to methyl mercury which is soluble and gets into the food
chain. Careful where you fish. There are relatively responsible
people who say that we have already irreparably polluted our water
supply with the stuff. Only a matter of about 50 years until
bacteria convert enough of the stuff to kill ourselves off. :-(
