Release of mercury from 8 different amalgams was tested in water initially and after annealing für 2 years. The measuring methodology was geared to warrant minimum mercury losses due to evaporation and adsorption. Mercury loss during the first 24 hours ranged between 17.4 micrograms/cm2.d and 34.5 micrograms/cm2.d. Annealing of the amalgams for 2 years reduced mercury leaching significantly, to about 1.5 micrograms/cm2.d with no significant differences between the different amalgam brands.
