5 páginas.-- Interdisciplinary Water Congress CINA 2014, Vigo, 2-6 June 2014Samples of water were withdrawn monthly close to the Das Mestas River
mouth, out of the tidal influence, from October 2011 to September 2012
(covering a hydrological year). After filtration through 0.45 policarbonate
membrane, nine trace metals were analyzed (Al, Co, Cu, Cr, Fe, Mo, Ni, Pb and
V) in the dissolved phase. All procedures were made following trace-metal-clean
techniques. Three groups of metals were distinguished: Al, Co, Ni, Cu and Pb
correlated with the SPM and the DOC indicating they are related with soil
leaching; Iron is related with Chl-a so its behavior depends on the biologic
activity; lithological influence on Cr, Mo and V patterns was observed.This study was supported by CTM2011-28792-C02
project, Land-sea exchange of trace metals and its importance for marine
phytoplankton in an upwelling coast (MITOFE), financed by Spanish MINECOPeer reviewe
