The dental status of 130 deceased Zurich people was evaluated from radiographs of their maxillary and mandibular dentitions taken during their autopsies. A mean mass of mercury of 2.49 +/- 0.37 g was calculated per dentate deceased based on the analysis of 134 extracted premolars and molars with amalgam restorations. The mercury contamination due to cremation in 1988 in Switzerland was calculated to vary between 45.8 and 79.0 kg, based on both the data from the sample analyzed and the fact that 55.5% of Swiss funerals were cremations, the average age of death was 73 and that 70% of the people of that age retained some of their teeth. Mercury contamination by cremation, therefore comprised only 0.61 to 1.53% of the total mercury contamination produced by all waste incineration methods. The minimal contribution to the mercury contamination due to cremation can thus not be used as an argument to ban the use of dental amalgams.
通过对130名苏黎世逝者尸检时拍摄的上颌和下颌牙列X光片进行评估，了解他们的牙齿状况。基于对134颗有汞合金修复体的拔除前磨牙和磨牙的分析，计算出每名有牙列的逝者体内汞的平均含量为2.49±0.37克。根据所分析样本的数据以及瑞士55.5%的葬礼采用火葬、平均死亡年龄为73岁且该年龄段70%的人仍保留部分牙齿这一事实，计算出1988年瑞士火葬造成的汞污染在45.8至79.0千克之间。因此，火葬造成的汞污染仅占所有垃圾焚烧方式产生的总汞污染的0.61%至1.53%。所以，不能以火葬对汞污染的贡献极小为由来禁止使用牙科汞合金。
