Metallic mercury is not the main problem. It’s the organic compounds it forms in nature or that are man-made. They are far from harmless. One drop of dimethyl mercury is deadly.
Here’s an interesting article.

Take a guess how many have died due to methyl mercury in the U.S.
Answer: Two
One was a hog farmer in New Mexico — fungacide
the other was a researcher...she dropped a drop of it on her arm. Died within weeks.
I am desperately looking for more. FREEPERS! Please post if you know of any. Thanks!
