Is phytostabilisation a sustainable technology for metal contaminated sediment deposit ?

Abstract : In this two-year project, we proposed to demonstrate thé long-term sustainability of phytostabilisation on a sédiment deposit site, highly contaminated with Cd and Zn, by addressing thé following points: (i) restoration of soil function and biodiversity (ii) ré- duction of mobility and bioavailability of metals, (M) sustainability and maintenance of thé végétation cover and soil amendment action and (iv) métal tolérance mechanisms and phytotoxic effects. The first results are discussed.
