Zinc isotopes in the Seine River waters, France: a probe of anthropogenic contamination.


The use of zinc (Zn) isotope ratios as a tracer of anthropogenic contamination has been assessed using an extensive collection of river water samples from the Seine River basin (France) collected between 2004 and 2007. The 66Zn/64Zn ratios (expressed as delta66Zn) of dissolved Zn have been measured by MC-ICP-MS after chemical separation of Zn using an… (More)
