AB This main aim of this work is the determination of the regional background in Holocene sediments of theGuadiana River estuary. These background values are essential in order to establish the environmentalquality of the most recent sediments, and to evaluate the possible incidence that some processes associatedto human activities (acid mine drainage, urban effluents) could produce in these sediments. For this purpose,a sedimentological and geochemical characterization have been done in two sediment cores from thelower Guadiana basin, in which Al normalized concentration has been calculated for the most importantmetals and metalloids present in these sediments (As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn).The resultsobtained have allowed us the determination of the regional background in these sediments
