Comportamiento del FE y otros metales en el agua de un sistema fluviomarino afectado por procesos de mezcla ácida (Ría de Huelva, España)

Abstract

Fe, Ni, Cu, Zn and Cd concentrations have been analyzed in 14 water samples in three cruises along of a estuary system affected by acid mixing processes. In the sectors of the estuary where the mixing processes takes place, Fe and heavy metals dissolved show to a behaviour non-conservativo vs pH and the conductivity. Even so the water of the marine zone contains still metal concentrations greater than typically marine waters
