Could mass spectrometry detect mercury?

[Guest guest]

Mass spectrometry is being used to determine body burden of depleted

uranium: http://www.newstarget.com/022503.html

Apparently it's being used for " ultratrace " (ooh, cool term) levels of

mercury as well, though I'm not clear on how this testing is performed.

Could this be used to determine body burden? Has it been done? Sites:
