RE: methods for cadmium and tin

From:Bert Dotson

Cadmium reacts with the aurine tricarboxilic acid (Aluminon) procedure. A 
0.5% sodium rhodizonate solution at pH 2.8 yields a brown-red precipitate 
with cadmium and should yield violet with tin (Lillie & Fullmer). There may 
be other staining methods for Cadmium from Japanese literature. It is an 
environmental problem there and has led to a debilitating bone disease 
called Itai Itai.

We have recently been examining tissue and found high levels of these two 
metals via chemical analysis. I wonder if anyone has methods to demonstrate 
either tin or cadmium in tissue.  They are FFPE samples.
Any help will be gratefully received.
