Introduction. Unreclaimed mine tailings represent an important environmental problem as aeolian dispersion and water erosion may transfer potentially toxic elements into local trophic webs and nearby human settlements (Mendez & Maier, 2008).Phytostabilization is a form of remediation that involves the use of plants for in-situ stabilization of tailings and …Web
