Geochemical characterization of surficial sediments from the southwestern Iberian continental shelf

The impact of trace elements (Ba, Nb, Zr, Y, Sr, Rb, Pb, As, Zn, Cu, Ni, Co, Cr, V, La, Ce, Nd, Sm, Eu, Tb, Yb and Lu) transported by the Guadiana, Tinto-Odiel and Guadalquivir rivers on sediments from the southwestern Iberian continental shelf has been studied. Shelf surficial sediments from three...

Shelf surficial sediments from three transects established right in front of the river estuaries were characterized by specific signatures relative to those trace elements. The Guadiana transect shows high Zr concentration values; the Tinto-Odiel transect shows high heavy metal (Pb, As, Zn and Cu) concentration values; and the Guadalquivir transect shows high Sr concentration values. Data from the statistical analysis indicate three distinct sources for trace elements: lithogenic, biogenic and anthropogenic. Se estudió el impacto de los elementos traza (Ba, Nb, Zr, Y, Sr, Rb, Pb, As, Zn, Cu, Ni, Co, Cr, V, La, Ce, Nd, Sm, Eu, Tb, Yb y Lu) acarreados por los ríos Guadiana, Tinto-Odiel y Guadalquivir sobre los sedimentos del sudoeste de la plataforma continental ibérica. Los sedimentos superficiales de tres transectos establecidos enfrente de los estuarios de los ríos se caracterizaron por las huellas específicas en lo que involucra a aquellos elementos. El transecto de Guadiana muestra valores altos de concentración de Zr; el transecto de Tinto-Odiel muestra valores altos de concentración para los metales pesados (Pb, As, Zn y Cu); y el transecto de Guadalquivir muestra valores altos de concentración de Sr. Los datos del análisis estadístico señalan tres fuentes distintas para los elementos traza: litogénica, biogénica y antropogénica. 2005-03-06 2021-06-03T03:54:58Z 2021-06-03T03:54:58Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Artículo Arbitrado https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/98 10.7773/cm.v31i12.98 https://hdl.handle.net/20.500.12930/7341 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/98/78 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 31 No. 1B (2005); 161-177 Ciencias Marinas; Vol. 31 Núm. 1B (2005); 161-177 2395-9053 0185-3880
