Abstract : The cleaning of waterways by regular dredging generates great volumes of sediments and, owing to human activities, these sediments often contain large amounts of metals (Cd, Zn, As, Pb) which are potentially toxic for plants and animals. Phytoextraction could be a solution to treat this kind of sediments. This work focuses on the mechanisms of Cd accumulation in Arabidopsis halleri, a Cd and Zn hyperaccumulator, and the effects of this species on a metal polluted sediment.
