Hi. I've reverted your addition of "arsenic" to this article, as the associated research has recently been strongly disputed, with some peer reviewers criticizing the experimental conclusions and opining that the replacement of phosphates by arsenates was not demonstrated. At the very least, it's way to early to factually state that arsenic can be used. -- Boing! said Zebedee (talk) 23:20, 21 January 2011 (UTC)
