Abstract

We have determined the concentration levels of some heavy metals (Hg, Cr(VI), Zn, Cd, Pb and Cu) in fluvial waters of the province of Valladolid (Duero River and its main tributaries) finding values lying on the normal ranges. We have also studied the pattern speciation of Zn, Cd, Pb and Cu in the river Pisuerga, polluted by municipal and industrial effluents, by using the speciation sheme devised by Nürnberg.
