James,
    For starters, I would cite those  toxic metals that are considered vital nutrients at relatively low dose levels including: Selenium,Copper, Zinc, Arsenic, Iron, and Chromium. I think you can buy these supplements at your local pharmacy. Incidentally, in other replies I received information indicating there very well could be hormesis  with Pb, Cd, & Hg also. I am sending you a more comprehensive review in a separate note.  Jerry Cohen
