“…The presence of Cd in this portion of the plant bound to oxygen ligands may be representing only the sorption of cadmium and not the transport. It is shown in the literature that when Cd sorbs onto non-living biological materials such as biomass of Hydrilla verticillata, Pseudomonas aeruginosa, and organic soil, the Cd coordination occurs to some extent through oxygen ligands of available carboxyl groups [28][29][30]. The EXAFS of the Cd sulfide, Cd roots, Cd shoots and Cd cotyledons are shown in Fig.…”

“…The cotyledon samples were found to have approximately 4 oxygen ligands with an interatomic distance of 2.22 Å. It is known that when S ligands become saturated or less abundant than O ligands, as in the case of corn cotyledons, Cd will bind through the O ligands from carboxylate groups to become a stable complex [30].…”

“…No caso do chorume, a presença de substân-cias húmicas com alta capacidade de complexar e adsorver metais pesados propicia um meio para adsorção dos mesmos. 22,[54][55][56][57] Outra justificativa é a interação deles com material particulado presente no chorume, uma vez que, de acordo com a literatura, 25,45,46 metais pesados podem apresentar elevadas afinidades por essas espécies.…”

“…dent spectroscopic studies (e.g., EXAFS), makes it possible to determine the binding strength of a metal to specifi c functional groups in NOM. This approach was successfully used by Karlsson et al (2007) to describe the binding of Cd to functional groups in a forest peat soil.…”
