In order to trace the sources of sediment materials and trace metals in the Weser River system (Germany), and the riverine input to the North Sea, Sr, Nd and Pb isotopes, together with multi-elemental compositions, were measured for sediments collected over the entire Weser River Basin, from headwaters to the estuary. Mass fractions of metals, including Ag, Cd, and Pb, and of one metalloid, Sb, higher than their crustal abundance, were observed within the entire Weser Basin. Isotope-amount ratio n(Sr)/n(Sr) and ε ranged from 0. Read More
