freshly added to soil before application to skin. Some limitations are noted for
this study. First, the in vivo study did not estimate arsenic retained in skin.
However, the researchers followed excretion of arsenic after exposure and noted
that excretion of the labeled arsenic was essentially over by day 7. The
remaining arsenic bound to skin proteins will probably remain there and not
present a risk of reaching the bloodstream.
Secondly, a sieved soil fraction of 180-300 µm was used, which does not reflect
the generally smaller soil particle fraction that sticks to skin following dermal
contact. Soil sieved to
