[Lead and cadmium occurrence in deciduous teeth of children exposed to cigarette smoke in apartments].
The aim of this study was to find out if children's exposure to tobacco smoke in the apartments influences the lead and cadmium content and the values of Pb/Ca and Cd/Ca ratios in hard tissues of their deciduous teeth. Material consisted of 71 shed deciduous teeth; 37 from children in the age of 6 to 13 years additionally exposed to tobacco smoke in the apartments and 34 from children in the same age, whose apartments were free of tobacco smoke. Lead, cadmium and calcium content was determined by means of flame atomic absorption spectrometry. Deciduous teeth of children additionally exposed to tobacco smoke in the apartments exhibited higher lead and cadmium content and higher values of Pb/Ca and Cd/Ca ratios, which indicated significant accumulation of these metals, when compared to deciduous teeth of children whose apartments were free of tobacco smoke.
