[Prevention of mercury vapor contamination resulting from scraps of silver amalgam and the remainder of mercury].
Silver amalgam is applied in large amount in clinical practice, which will result in mercury vapour contamination of the stomatological environment. It is important to dispose properly of the scraps of silver amalgam and the remaining mercury, in order to reduce mercury vapour. This experiment shows that X-ray fixer solution is apparently more effective than water in preventing the escape of mercury vapour. Furthermore, such solution is available in hospitals and the used solution can also be utilized. The proper storage of silver amalgam scraps and the remaining mercury in X-ray fixer solution is apparently more effective than water in preventing the escape of mercury vapour. Furthermore, such solution is available in hospitals and the used solution can also be utilized. The proper storage of silver amalgam scraps and the remaining mercury in X-ray fixer solution will help to reduce the level of mercury vapour contamination of the stomatological environment.
