ABSTRACT
Introduction:
Teeth are considered one of the better indicators of environmental exposure to heavy metals, especially in exposure from early childhood. The aim of the study is to assess the suitability of primary teeth as an environmental indicator of exposure on Cd, Pb and Zn of children living in Bytom.
Material and Methods:
The analysis included 45 primary teeth of children aged 2–14, living in Bytom. Primary teeth were subjected to the mineralization process. In the samples, the concentration of cadmium, lead and zinc by the method of atomic absorption spectrometry was determined.
Results:
The analysis showed differentiation of Cd, Pb, Zn concentrations in primary teeth. Concentrations of selected heavy metals in teeth in the group of children from 2 to 14 years were in the ranges: 0.002–1.352
Conclusions:
The results of chemical analysis of collected primary teeth of children living in Bytom indicate a limited possibility of using them as an environmental indicator of exposure of children to cadmium, lead and zinc. It seems that prenatal exposure of children may be a interfering factor.
