Trace metals in sediments from the "Ria de Huelva"

The Ría de Huelva is an estuarine zone into which flow the Odiel and Tinto rivers, polluted by trace metals. Total contents of Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Pb, Cd and Hg were determined in the < 630 and < 63 μm fractions of bed sediments. Total trace metal contents in the coarsest fract...
