| Abstract |
Deciduous teeth have a unique characteristic that exposure chemicals accumulated at the prenatal period and at the postnatal period are spatially separated by the neonatal line in their microstructures. Because of this feature, deciduous teeth have been regarded as retrospective temporal biomarkers. In addition, deciduous teeth can provide direct signatures of fetal period exposures whereas other frequently-used biomarkers such as maternal blood, maternal urine, and cord blood can only give indirect ones. In the previous studies, we tried to develop a quantitative elemental analysis method for deciduous teeth by employing a microwave-assisted sample preparation method and inductively coupled plasma dynamic reaction cell mass spectrometry (ICP DRC MS). In this study, we validated a developed method with the bone meal standard reference material and applied a validated method to individual deciduous tooth samples. As a result, concentrations of over ten elements were successfully determined from five individual tooth samples and compared.
