Good grief. There is lots of mercury in the environment including in sea air, and there are completely unknown biological pathways metabolising it as was shown by the atmospheric research station at Cape Point. The general idea is that mercury is well "mixed
in the atmosphere". Not so. Sometimes it drops to zero in the air blowing from Antarctica for hours at a time. There is no known process that can do this. Most atmospheric mercury is from the sea. </div>

I am amazed that these coal memes survive for so long. There is a really good lab at Clarkson Univ in Potsdam NY that researches Hg in fish in the Great Lakes. Fantastically small quantities can be detected. One sandwich a week? </div>

<div>Frans and Crispin,</div>
<div>Thanks for putting dimensions on the issue. I know that coal ash is the bad actor. </div>
<div>I'm still perturbed that I can only eat one tuna fish sandwich a week because of the Mercury from coal. C'est last game. <br>
