use of deciduous teeth as a biological indicator for lead exposure among school children in three different Egyptian environments

ABSTRACT

The lead content of teeth [Pb T] and blood [Pb B] of school children in the different Egyptian environments were measured to determine the relative contribution of atmospheric lead pollution. The school children of the industrial area showed a statistically higher mean Pb T and Pb B than those of urban and rural area. Moreover, there was a significant positive correlation between Pb B and lead in different teeth of the examined group
