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 potential. The non-vegetated mine-tailing substrate showed a high contení of metals, mainly copper (&gt; 2.5 g kg-1), a pH 7.4, high contení of salts and 5.0 % organic matler. Vegelaled palches al íhe lailing showed similar characlerislics of pH, salís and organic maller conlenl, and showed a lolal copper concenlralion lower íhan íhe conlenl found ai íhe non-vegelaled patches. Nine plant species present at the site were screened for copper accumulation and...
