The rate of mercury vapor emission from setting dental amalgam was measured by use of an ultraviolet light absorption technique under nondiffusion-controlled conditions. An average of 0.3 X 10-6 gm mercury per square centimeter was emitted at the experimental temperature. At 37 C, this amount was estimated to be 1.2 × 10 -6 gm/ cm2.
