Summary: Mercury emissions from single-spill samples of three popular precapsulated amalgams, Tytin, Dispersalloy, and Valiant, were measured in water at room temperature, 23o C. Daily emission was 4.5 to 21 micrograms per day, much higher than previously "estimated" values offered by ADA spokespeople in the past. It is now obvious why pro-amalgamists never actually measured these values.
