Phytoremediation Potential of Native Herbaceous Plant Species Growing on a Paradigmatic Brownfield Site

Abstract Phytomanagement techniques using native species allow the recovery of contaminated soils at low cost and circumvent ecological risks associated with use non-native species. In this context, a paradigmatic brownfield megasite highly by As Pb was sampled in order to analyze soil–plant interactions identify plant phytoremediation potential. A survey first carried out 20-ha area obtain an inventory growing spontaneously throughout site. We then performed another most polluted sub-area (1 ha) within Pseudototal concentrations contaminants soil, aerial parts plants, roots were measured ICP-MS. detailed habitat classification done, specific index coverage applied means 1-year quadrat study various sampling stations. Results converged selection six herbaceous ( Dysphania botrys , Lotus corniculatus hispidus Plantago lanceolata Trifolium repens Medicago lupulina ). All these plants are fast-growing, thereby making them suitable for phytostabilization strategies. Furthermore, they all easy grow propagate generally self-sustaining. showed accumulation factors below 1, thus revealing as pseudomethallophytes excluders. However, L. M. translocation capacity considered worthy further study.
