AB The Odiel river estuary shows a strong longitudinal gradient in pH and Conductivity values of the water, inagreement with the acid neutralization processes and salt-induced mixing that occur in the middle andthe upper sectors of the estuarine system. The Odiel river supplies high REE dissolved (128.8 μg·l-1) thatdiminishing progressively until the middle zone of system (1.2 μg·l-1). In the particulate phase the REEconcentration ranges between 237.8 and 48.1 mg·l-1, displaying the greater concentrations in the middlezone of the estuary. The middle and high dissolved REE are the first transferred to the particulate phase,causing a light REE depletion in the upper sectors of the mixing zone (pH between 4.2 and 5.7). The lightREE transference takes place at the end of the acid neutralization processes (pH > 7), concluding in themarine zone of the estuary
