With respect to leaching from dental fillings or other amalgams, professor Boyd Haley of the University of Kentucky (and outspoken critic of the American Dental Association) told me that if you measure the vapor concentration of mercury in the mouth of a person with amalgam fillings that it exceeds the PEL for airborne mercury in the workplace.  Food for thought!

I was actually interested in what that 0.2% "impurity" was that kept the
mercury solid at room temperature.  Anybody know?  I'm betting that
egg-shaped mercury orb in the pool is way less than 99.8% pure.  But if
it's like amalgam dental fillings, maybe very little mercury is leached
out.  That would make sense, considering that some of these things are
probably centuries old and still look new.
