Se realizó el análisis de los metales pesados en dos suelos, el pardo con carbonato y el oscuro plástico gleysoso, y en diferentes órganos de la planta, mediante espectroscopia de absorción atómica. Los experimentos fueron realizados a nivel de laboratorio mediante sistemas fitorremediadores experimentales, con condiciones más controladas y en el sitio contaminado, donde solo se analizó el suelo pardo. Los coeficientes biológicos de fitorremediación obtenidos, tanto para los sistemas experimentales como en los experimentos realizados in situ, fueron superiores a uno, excepto en el coeficiente de absorción biológica en la raíz para el plomo. Este resultado está en correspondencia con las mayores concentraciones de plomo obtenidas en las hojas con respecto a la raíz. Los coeficientes de remediación obtenidos muestran que el Romerillo americano presenta capacidad de bioacumular el cadmio y el plomo existente en ambos suelos.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT In the present research, was to determine the remediation coefficients of cadmium and lead of American Romerillo in soils contaminated. The analysis of heavy metals in two soils, the brown soil with carbonate and the dark plastic gleyseous, and in the different organs of the plant, was carried out by atomic absorption spectroscopy. The experiments were conducted at the laboratory level using experimental phytoremediation systems, with more controlled conditions and at the contaminated site, where only the brown soil was analyzed. The biological phytoremediation coefficients obtained, both for the experimental systems and in the in-situ experiments, were greater than one, except for the root biological uptake coefficient for lead. This result is in correspondence with the higher lead concentrations obtained in the leaves with respect to the root, showing the plant's capacity to assimilate this metal. The remediation coefficients obtained show that the American Romerillo has the capacity to bioaccumulate cadmium and lead in both soils.]]></p></abstract>
