Potential adaptation of Miscanthus x giganteus for the phytoremediation of a former mine site highly contaminated
Year: 2011
Type: dissertation
Abstract: Contaminated soils such as former mine sites are unsuitable for the food production. Metals and metalloids concentration are usually very high. The main aim of this thesis was the evaluation of the adaptation capacity of a bioenergetic plant, Miscanthus x giganteus, on soils developed from mining wastes contaminated in arsenic (10% in mass concentration) and lead (5%, mass concentration). Despite the contamination, results show that: (i) Miscanthus is able to adapt without any physiological stress, (ii) biomass yield is reduced, (iii) soil to plant transfer of As and Pb is low owing to a specific mineralogy limiting the elements solubilization, (iv) microorganisms involved in nitrate formation are present and (v) M. x giganteus is an excellent plant to phytostabilise the site
