DearJonathan,
The oxygen example isn't a direct analogue because oxygen isn't partitioned between the gaseous and aerosol phases. Therefore there is no ambiguity resulting from 'gaseous' being implicit. Mercury is present in both phases making it different and needing 'gaseous' stated explicitly.
My understanding of divalent mercury would be Hg++ ions, quite different from Jonathan's, so a clarification would be appreciated.
Cheers, Roy.

Dear Christiane
Could we omit "gaseous"? We would not say "gaseous oxygen in air", for
instance. I think one would assume that constituents of air are gaseous
unless they are explicitly said not to be e.g. aerosol, liquid water.
Does "divalent mercury" mean Hg2 molecules?
Best wishes
Jonathan
