Resumen

This study consists of the determination of lead concentration contained in soil and plant material (Brickellia veronicifolia) by means of Differential Pulse Anodic Stripping Voltammetry, using vitreous carbon as working electrode, SCE as reference and platinum as auxiliary. Samples were collected from sites near a tailings dam belonging to San Martin-Sombrerete-México; taking 12 sampling points and analyzing the lead content in soil and plant (root, stem, leaf), for determining the accumulation of this toxic element, in order to define its possible use as phytoextractant. The detection and quantification limits were 0.8 and 1.9 ppb respectively; it was found that the highest lead concentration was 1, 115 ppm, which corresponds to 2.87 times the value established in NOM-147-SEMARNAT/SSA1-2004 for contaminated sites, while the plant accumulated 730 ppm with accumulation averages of 20-35% in root, 11-30% in stem and 37-58% in leaf, inferring that is an indicator plant of lead contamination in soil.
