Dear Jonathan,
Mercury in the atmosphere is always a positive ion, only under extreme
conditions can it be negative. Therefore the 2plus is not necessary.
However, in the chemical community the use of mercury_II instead of
mercury_2 is more common, as use roman numerals are used to indicate an
atoms oxidation state. Hence I suggest:
mercury
mercury_II
mercury_dry_aerosol (to be consistent with other aerosol species)
(More comments on the use of X_as_Y in a next email.)
Best regards,
Christiane
> mercury_0 is elemental mercury in the gas phase,
> mercury_2 is oxidised mercury in the gas phase,
> mercury_aerosol is mercury emitted from antrhopogenic sources associated with particulate matter.
