Resumen o descripción
Lead concentration in soils has been measured
in Vetagrande, an old mining town located at the state of
Zacatecas in Me´xico. Eighty nine soils samples were
analyzed using Energy Dispersive X-ray Fluorescence. The
lead concentrations were treated with the Kriging method
in order to estimate the lead concentration distribution in
the studied area. Pb levels in soils were from 8 to 7730 lg
kg-1, where 28.1% of soil samples have less than 400 lg
kg-1, 71.9% is above 400 lg kg-1 which is the maximum
level recommended by the EPA for residential use of soil.
Lead concentration measured around public sites represent
a risk of lead intake in the population.
