Analysis of elements in enamel of deciduous teeth as a biomarker for fetal environment

本文对乳牙釉质中的微量元素进行了研究，以评价其致死环境。乳牙包括出生前形成的釉质和出生后形成的釉质。它们通过新生儿线来区分。建立了微量PIXE分析方法，在不破坏牙釉质结构的前提下，对出生前后牙釉质中的微量元素进行了测定。胎儿期牙釉质中含有不同浓度的Na、Mg、Zn、Sr、Fe等微量元素。

Trace elements in enamel of deciduous teeth were investigated in order to assess the fatal environment. Deciduous teeth include both pre-natal formed enamel and post-natal formed enamel. They are distinguished by neonatal line. We established the analytical method using micro-PIXE, by which trace elements including pre-and post-natal enamel are measured without destruction of their structure. Some trace elements, Na, Mg, Zn, Sr, and Fe were in prenatal enamel with various concentrations.
