Determination of Lead in Deciduous Teeth Using Graphite Furnace Atomic Absorption Spectrometry

Abstract

This study's goal was to determine the amounts of lead in schoolchildren's deciduous teeth from Turkey's Erzurum, Tuncbilek, Yatagan, and Didim. 50 girls and 54 boys aged 7 to 11 had their 104 deciduous teeth collected. Atomic absorption spectrometry was used to measure the lead amounts. Limits for detection and quantification have also been estimated, along with the method's linearity, precision, and accuracy. A linear response was seen for lead concentrations ranging from 10 to 1000 ng/mL. Repeatability of the method gave Relative Standard Deviation (RSD) of ≤ 3.87 %. Tuncbilek and Yatagan are suburban areas that have thermo electrical centrals. The mean levels of lead in Tuncbilek and Yatagan were found as 12.44 ± 4.53 μg/g and 8.48 ± 3.53 μg/g, respectively. Erzurum is an urban area by heavy traffic and air pollution and the mean level of lead in this area was found as 7.49 ± 2.71 μg/g. Didim is a suburban area. The mean level of lead was found as 9.49 ± 3.54 μg/g.
