Factores que condicionan la disponibilidad de elementos traza del suelo en repoblaciones forestales de la cuenca del río Guadiamar (Sevilla)

Abstract

En este trabajo se analizan los patrones de biodisponibilidad de elementos traza (ET) en suelos contaminados por un vertido minero y que han sido reforestados en la Cuenca del Guadiamar (Sevilla). A lo largo de un gradiente de contaminación, se analizaron los contenidos totales de ele- mentos traza del suelo, así como los niveles biodisponibles y otros factores físico-químicos (textura, pH, nivel de carbonatos y materia orgánica, y capacidad de cambio) y se compararon con los nive- les acumulados de ET en las hojas de plantones de encina ( Quercus ilex subsp. ballota ) y álamo blan- co ( Populus alba ), plantados en los suelos analizados. De todos los factores analizados, el pH fue el que más influyó sobre los niveles biodisponibles de elementos traza del suelo. Sin embargo, estos niveles tuvieron escasa influencia en la acumulación foliar de elementos traza de las especies estu- diadas, con excepción del Zn en las hojas del álamo blanco. Los resultados sugieren que, a pesar de que los factores edáficos pueden controlar los niveles disponibles de estos elementos en el suelo, dis- tintos mecanismos fisiológicos a nivel de especie (como la capacidad de retención de ET en la raíz) pueden resultar más determinantes para la traslocación y acumulación de los elementos traza en las hojas, donde podrían causar distintos efectos ecotóxicos.
