Hi all,
I have noted that the old SGVs for some of the metals (Hg, As, Cd, Mi, Se and
Cr) have been produced using the oral exposure route only. They give the
following justification,
"Dermal and inhalation routes have been excluded from this comparison
because, for many types of arsenic contamination and in the context of the
stardard land-uses the contribution of these pathways to overall exposure will
be much less than 1%".
Is this principal still applicable for the current model? I can't find any
reference to it in the recent documents.
Thanks in advance for your help.
Charlie
