Abstract:
Metal release from 13 different gold-containing jewelry alloys stored for 1 and 3 weeks in artificial sweat was analysed. For chemical analysis, inductively-coupled plasma detection (ICP) and atomic absorption spectrophotometry (AA), with flame and with furnace, were used. No release of gold was detected. It is unlikely that skin contact with gold-containing metallic items such as jewelry is responsible for inducing contact allergy to gold or allergic contact dermatitis due to the gold. The patch-test reactivity to gold sodium thiosulfate needs to be explained by some other mechanism(s).

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...
