Abstract

The purpose of the study was to determine the accumulation of lead in deciduous teeth in children living in the area of Pamplona (Spain). In this manner, we tried to make a relationship between the quantity of lead accumulated in the tooth against certain factors of exposure that were documented on a questionnaire carried out at the time that the tooth was presented. We analysed 457 deciduous teeth using a technique of microwave digestion follow by Atomic Absorption Spectrometry (AAS), to determine the concentration of lead in the sample. The mean lead concentration was 2.60+/-1.36 microg/g (range 0.25-10.71 microg/g). The lead concentration in our study is inferior to those observed in other European studies.
