Résumé
The establishment of a suitable geochemical baseline for soils and sediments is of essential importance in exploration: geochemistry and environmental studies related to heavy metal pollution. Notwithstanding that obtained reference values depend directly on different factors such as sample material collected, grain size and analytical procedures, several methods have been used to estimate the natural concentrations of heavy metals and arsenic in the sediments from the Santander bay, and the appropiateness of the proposed background values is discussed
