RT Journal Article T1 Variación en el fraccionamiento de Tierras Raras en la materia en suspensión de la Ría de Huelva (SO de España) T1 Variation partitioning of Rare Earth Element in suspended matter of Ría de Huelva (SW Spain) A1 Carro Flores, Berta A1 Borrego Flores, José A1 López González, Nieves AB Concentrations and partitioning of particulate rare earth elements are studied in an estuary affected by acidmine drainage. A sequential extraction procedure was applied to 14 suspended matter samples collectedfrom four cruises. The results show that easy reducible fraction are mainly linked to LREEs>MREEs=HREEs.The total concentration of REEs in the suspended matter varies according to the volume of the fluvialcontributions that arrive at Ría, thus these increases significantly at the times of greater contribution YR 2007 FD 2007 LK http://hdl.handle.net/10272/8380 UL http://hdl.handle.net/10272/8380 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 29 may 2026
