Seasonally distribution of the lanthanides in the suspended matter and dissolved phasehas been studied during a hydrological year in the estuary of the Odiel River. In his system affected by acid mine drainage take place the coexistence of two water mixture processes; a process salt-induced mixture typical in an estuary and a process of acid water neutralization. In the mixing zone of the estuary there is a removal of the dissolved phase to the suspended matter out of the system. REEs concentrations are controlled by the volume of discharge of the river and degree of neutralization process. Thus, during first rains after a dry period, the gradient in concentration of these elements in the mixing zone ismore pronounced in this system.
