Tooth lead concentration as an indicator for environmental lead pollution in Cairo

A comparison of lead burden of children deciduous teeth collected in suburban and urban areas of Cairo was undertaken. This comparison was determined by calculating the concentrations of lead levels in teeth shedded from children living in both regions. A significant correlation was established and the results proved that children who live in Cairo City have a relatively high degree of tooth lead contamination, especially in the urban area. These data should encourage the Egyptian authorities to increase the control of lead emission sources
