Abstract
Synchrotron micro X-ray fluorescence has been used to study differences in the trace element concentration between the dentine and cementum rings of human teeth. The results show that metals such as zinc are concentrated in the cementum rings. This suggests that if the rings are deposited annually a temporal record of metal exposure may be extracted from this material.
摘要
同步加速器微X射线荧光已被用于研究人类牙齿牙本质和牙骨质环之间微量元素浓度的差异。结果表明，锌等金属集中在牙骨质环中。这表明，如果这些环是每年沉积的，那么可以从这种材料中提取出金属暴露的时间记录。
