RT Journal Article T1 Selección del fondo geoquímico para metales pesados en sedimentos actuales: aplicación en la bahía de Santander T1 Establishment of heavy metal baselines for recent sediments: A case study in the Santander Bay A1 Irabien, María Jesús A1 Yusta, Iñaki AB 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 PB Sociedad Geológica de España YR 1999 FD 1999 LK http://hdl.handle.net/10272/10138 UL http://hdl.handle.net/10272/10138 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 17 jun 2026
