Copper distribution in leaves and roots of plants growing on a copper mine-tailing storage facility in northern Chile
In a copper mine-tailing afforested we characterized the physicochemical properties of the substrate at vegetated and non-vegetated patches. We studied the accumulation of copper in roots and leaves of the species present at the site, to evaluate their phytoextraction and/or phytostabilization poten...
