AB This work has been developed with the aim of determining the environmental quality of the sediments inthe Guadiana river estuary, and evaluating the possible incidence that some processes associated to humanactivities (acid mine drainage, urban effluents) could produce in this sediments. For this purpose, thegeochemical and granulometric characterization of the estuary sediments have been determined, and theenrichment factors have been calculated for the most important metals and metalloids (As, Cd, Co, Cr,Cu, Fe, Mn, Ni, Pb and Zn).The results obtained evidences a distribution of the metals and metalloids intwo groups: Group I with elements with a natural origin ( Al, Fe, Mn, Co, Cr and Ni ), and Group II, withelements associated to an anthropic origin ( As, Cd, Cu, Pb and Zn ). The enrichment factors for theelements of the Group II, are indicative of the existence of a diffuse mining contamination, associated withthe acid mine drainage of internal zones of the basin. There has been also found out anomalousconcentrations of some of these elements near the villages of Ayamonte and Villa Real de Sto Antonio
