Abstract
The objective of this work was the quantification of lead (Pb) in soil samples in specific areas in the city of Presidente PrudenteSP, where one of the features of the physical environment of this region is its proximity to areas with strong evidence of a geological fault. Samples were collected at pre-established regions according to the data regarding the emanation of Rn, and also collected soil profiles in the district of Montalvão. Analyzes of Pb using the anodic stripping voltammetry with mercury electrode was satisfactory and proved to have a low detection limit. The concentration of Pb were one hundred lesser in soil samples collected in rural areas, generating the hypothesis of influence of emanation of Rn in Pb concentration. The granulometry analyzes and MEV were used to characterization soils samples.
