Sažetak
The objective of this study was to compare lead concentrations in 86 human permanent teeth extracted from residents
of three different geographical regions. The study included 31 permanent teeth from residents of Mitrovica (Kosovo), 32
from Klina (Kosovo) and 23 from Graz (Austria). The concentrations of lead were measured using Agilent 7500c inductively
coupled plasma mass spectrometer (ICP-MS) (Agilent, Waldbronn, Germany). The comparisons between groups
were based on the geographic area, age and gender. The highest lead level was found in teeth extracted from Mitrovica
residents (22.3 mg/kg), followed by Klina (3.2 mg/kg), and Graz (1.7 mg/kg). Lead levels in teeth from Mitrovica residents
are significantly higher (p<0.0001) than in other two groups, possibly due to environmental contamination with
lead. Overall results in this study support the concept that tooth lead level may present an important indicator in evaluating
environmental exposure of human population to heavy metals.
