dc.descriptionVertical distribution of some rare earth elements (REEs) and trace elements through a Jurumirim Reservoir sediment core is presented. REE fractionation using BCR sequential extraction protocol was performed to verify REE mobility in the environment. Three steps (exchangeable, reducible, oxidizable) and residual fractions were studied and REE distribution for each was evaluated by ICP-MS. REEs showed a higher affinity for the reducible phase. Instrumental neutron activation analysis was also applied to sediment samples to determine the total mass fraction for some REE (Ce, Eu, La, Lu, Nd, Sm, Tb, and Yb). The diagrams normalized to chondrite values were used for a REE distribution pattern evaluation.
