Yes both soluble beryllium salts and powdered beryllium metal even applied to the skin are known to cause sensitization and is a route into the bloodstream where it is highly carcinogenic (I am not speaking from experience!).
Yet strangely the one source of beryllium that many people (at least the more well-off among us) commonly come into contact with, namely the gemstone emerald Be3Al2(SiO3)6 obviously has no known toxic effects whatosever! Apparently even gemstone grinders show no ill effects! I guess it's the free Be2+ ion that's so toxic. Cheers -- Ian On Tue, 2 Apr 2019 at 13:07, Aaron Finke <af...@cornell.edu> wrote: > 1.
