Cd localization and speciation in a contaminated sediment and in the Zn and Cd hyperaccumulating plant Arabidopsis halleri

摘要：

The purpose of this work was to characterise the chemical speciation of Cd in a Zn- and Cd- contaminated dredged sediment subjected to a phytoremediation treatment with the hyperaccumulator plant Arabidopsis halleri. The investigations were performed using analytical chemistry, scanning electron microscopy and synchrotron techniques including X-ray microfluorescence and X-ray absorption spectroscopy (EXAFS and XANES). The paper focuses on the initial state of the sediment before the beginning of the phytoremediation treatment.
