The deep lung environment is likely to be the principal route of metal transfer from indium-tin oxide into the bloodstream. Indium-tin oxide is also soluble in stomach acid, but the short residence time limits metal transfer into the bloodstream. Trypsin (and possibly other digestive enzymes) may enhance the solubility of indium-tin oxide in the digestive tract Indium-tin oxide is inert in the upper respiratory tract, although minor fractional dissolution of tin may occur.
