Could you give us some specific citations for evidence of biological necessity for arsenic and lead? I searched on PubMed but couldn't find anything.

It is damn near impossible to search on Google for this literature today. Fortunately, some of the links have been posted to this site before, which is searchable. :)
Here is the first good reference I could find, which surveys some of the other literature. It mentions lead in rat models.
