The occurrence of metals in human teeth in relation to environmental exposure
The aim of this study was to determine physiological and toxic metals in the teeth of inhabitants of Ruda Slaska and Bielsko-Biala - differently polluted areas - and to find out if environmental exposure to heavy metals has an influence on the occurrence and coexistence of these metals in teeth. The material consisted of 401 permanent teeth from inhabitants of these two cities. The contents of Cd, Cr, Cu, Fe, Mn, Pb, Zn, K, Na, Ca and Mg were determined by means of flame atomic absorption spectrometry. We concluded that environmental exposure to heavy metals has an influence on the occurrence and coexistence of these elements in teeth.
