The lead is a toxic metal used in many industrial processes, however, due to its persistence in the environment affects human health seriously. Our country is not beyond to this pollution, Callao Constitutional Province is one of the most polluted cities where children are the most affected. Being the lead a genotoxic agent, it is important to realize genotoxicity tests to the affected population to determine the damage caused by this agent in the organism. This work joined the lead’s genotoxic effect through micronucleus presence in children of school population exposed and not exposed to this metal. A comparative cross-sectional study was made in 80 children aged 6 to 13 years; 40 resident children in the A.A.H.H Puerto Nuevo – Callao considered group at risk and 40 children residing in Magdalena considered group control. The genetic damage was determined by the micronucleus technique with cytokinesis block in peripheral blood, the lead levels in blood were blood test using the Atomic Absorption Graphite Furnace technique. Data were analyzed using Spearman and Umann Whitney non parametric tests with the help of the statistical package SPSS 15; obtaining blood lead level in the total population, it was 5.24 ± 3.00 ug/dL; in the group at risk 6.90 ± 2.55 ug/dL and the control group 3.57 ± 2.48 ug/dL micronucleus percentage in the total population was 8.34 ± 6.00 ‰; in the group at risk 12.33 ± 5.53 ‰ and the control group 4.35 ± 3.16 ‰. The relationship between micronucleus and lead levels in the total population was r = 0.658; in the group at risk r = -0.068 and the control group r = 0.763. The relationship between micronucleus percentage and the total population age was r = 0.255; in the group at risk r = 0.699 and the control group r = 0.154.
