Zn, Cr and Fe speciation in river materials

摘要：

We have investigated the fate of metallic contaminants in the vicinity of the junction of two rivers. The collected materials, sediments and suspended particulate matters (SPM) display high level of contamination, notably due to high contents in metallic and organic pollutants. X-ray Microfluorescence experiments revealed strong differences in the spatial distribution of metals Fe, Zn and Cr. X-ray absorption spectroscopy at these elemems edges demonstrate the high degree of heterogeneity at the micronic scale.
