Presence of Cr, Cu, Fe and Pb in sediments underlying mussel-culture rafts (Arosa and Vigo rias, NW Spain). Are they metal-contaminated areas?

Despite the world-wide expansion of mussel aquaculture, there is still a lack of knowledge of the accumulation of metals in sediments underlying raft polygons. This is addressed in the present study in one of the most productive areas: the Galician rias (50% of total world mussel production). Surfac...

This is addressed in the present study in one of the most productive areas: the Galician rias (50% of total world mussel production). Surface and subsurface sediment samples were taken from the inner, middle and outer polygon zones along the Arosa (2292 mussel rafts) and Vigo (487 rafts) rias. The concentrations measured in the sediment fine fraction ranged from 70 to 154 µg g–1 for Cr, from 25 to 92 µg g–1 for Cu, from 28 to 37 mg g–1 for Fe and from 35 to 239 µg g–1 for Pb. Only a certain contamination was detected in the underlying surface sediments of polygons from the inner (Cu, Pb) and middle (Pb) zones of Vigo Ria; however, the increase in metal concentrations in sediments below rafts depends more on landbased anthropogenic sources than on the presence of mussel rafts or biomagnification processes.A pesar del aumento en los maricultivos de mejillón sigue faltando información sobre la presencia de metales en los sedimentos bajo los polígonos de bateas. Esta cuestión se aborda en el presente artículo para una de las áreas más productivas: las rías gallegas, donde se recoge la mitad del mejillón cultivado a nivel mundial. Se extrajeron muestras de sedimento superficial y subsuperficial bajo polígonos en las zonas interna, media y externa de las rías de Arosa (2292 bateas) y Vigo (487 bateas). Las concentraciones de metales medidas en la fracción fina del sedimento estuvieron en un rango de 70–154 µg g–1 para Cr, 25–92 µg g–1 para Cu, 28–37 mg g–1 para Fe y 35–239 µg g–1 para Pb. Bajo las bateas, solamente se ha detectado contaminación por Cu y Pb en la zona interna y por Pb en la media de la Ría de Vigo. No obstante, el aumento en el contenido de esos metales depende más de su cercanía a las fuentes antropogénicas litorales contaminantes que de la presencia de cultivos de mejillón.Iniversidad Autónoma de Baja California2006-08-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Article Artículo Arbitradoapplication/pdfhttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/110010.7773/cm.v32i22.1100Ciencias Marinas; Vol. 32 No. 2B (2006); 339-349Ciencias Marinas; Vol. 32 Núm. 2B (2006); 339-3492395-90530185-3880reponame:Ciencias Marinasinstname:UNIVERSIDAD AUTÓNOMA DE BAJA CALIFORNIAinstacron:UABCenghttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1100/1916info:eu-repo/semantics/openAccessoai:cienciasmarinas.com.mx:article/11002024-08-22T17:01:38Z
