Seventy-nine primary (deciduous) teeth were excavated in 1978 underneath the floor of the stave church in Uvdal, Buskerud County, Norway. The mercury content of 57 teeth was measured by means of cold vapor atomic absorption spectrophotometry. As a comparison, 124 primary teeth from modern Norway were analyzed. A significant statistical difference was found between the two sets of material. In the Uvdal material a correlation was found between the mercury and copper contents. For the modern material a correlation was found between mercury and lead, and between mercury and zinc. The authors maintain that the values found for the Uvdal material represent base-line values for mercury in primary teeth, and probably reflect uptake from natural environmental sources only. Furthermore, these values may be used for reference in studies of other preindustrial, as well as modern, primary teeth. Our findings also indicate a higher level of mercury in modern than in preindustrial primary teeth in Norway.
1978年，在挪威布斯克吕郡乌夫达尔的一座木板教堂地板下发掘出了79颗乳牙。采用冷蒸气原子吸收分光光度法测定了其中57颗牙齿的汞含量。作为对比，对来自现代挪威的124颗乳牙进行了分析。两组材料之间存在显著的统计学差异。在乌夫达尔的材料中，发现汞含量与铜含量之间存在相关性。对于现代材料，发现汞与铅之间以及汞与锌之间存在相关性。作者认为，乌夫达尔材料中发现的值代表乳牙中汞的基线值，可能仅反映了从自然环境来源的摄取。此外，这些值可用于其他工业化前以及现代乳牙研究的参考。我们的研究结果还表明，挪威现代乳牙中的汞含量高于工业化前乳牙。
