-- Lead is a metal distributed in the environment. The environment pollution comes from mainly of tetraethyl lead from gasoline and of the diverse emissions of industrial processes where to take part compounds of lead. In this present job of investigation it was determinates the polluted concentration of lead in soils of 21 houses from the Human Settlement Cultura y Progreso in the district of Ñaña - Chaclacayo during the month of February of 2006. The sampling method used was the recommended by EPA (Environmental Protection Agency) and the methodology for the analysis of the samples was the Spectrophotometry of Atomic Absorption of graphite Furnace. It exists a direct relation between the lead concentration in soil and roof of the houses and distance with the nearby factories; samples were taken in 3 blocks near to some factories, the block more nearly to the factories presented a higher vakue of lead concentration and the block farthest presented a lower value of lead concentration respect to the others 2. The results obtained indicate that 90.24% of the samples analyzed exceed the limit value established for the W.H.O. which is 25 mg/Kg in soil. For this reason is recommended to do periodical monitoring of lead contamination in soils for controlling its emption and toxicity in the environment.
