MM/QM study: Interactions of copper(II) and mercury(II) with food dyes in aqueous solutions

Complexes forms with mercury are easier to form and more stable than copper. These show that the mercury intoxication is faster than the copper, knowing that mercury is toxic even with low dose. For that, the men who carry amalgams, we advise may be avoid to eat food and drugs which contain azo dyes because there exists a high trend between these azo dyes and the metal ions which released by the amalgams.
