Abstract : I propose to examine the relationship between a food and Analzenk contamination of lead in children's body using the Banat available. The above objectives were achieved by measuring the concentrations of zinc and lead in the hair of 400 children in the first year of primary school using atomic spectrometry. Detailed methods have been developed to collect samples of hair and cleaned and melting and processing solution is appropriate for the measuring device called the atomic spectrum and to ensure the accuracy of the measurements. Found that the average values ​​of zinc and lead in Mecca was 160.2 micro g / g, 17.4 micrograms / g, respectively, while the values ​​of the city of Riyadh, 198.9 micrograms / g, 5.1 micrograms / gram. These results reflect the duplication of similar levels of zinc and lead all the data four hundred sample any important relationship, but when you compare the current values ​​of lead in hair (greater than 30 micrograms / g 9 with the values ​​attached to the nick in the hair found an inverse relationship good between them. Shows that high levels of lead in the hair have a significant effect in reducing the levels of zinc in the hair. This collection of data for the possible existence of the effect of lead metal Alsems metal zinc in the diet of children who have been studying.
