Extract

The chemical and mineral analyses of river and stream sediments are often employed for geochemical exploration. Their contents are considered to be representative of part or all of the catchment area. In environmental science the analysis of sediments provides information concerning the hydrochemical and ecological interactions of the water and their changes with time. Local and/or time dependent contamination of water bodies can also be determined by analysis of their sediments.

In this work, we have first performed qualitative elemental scans by both energy dispersive (radioisotope excited) and conventional wavelength dispersive X-ray fluorescence of the different grain size fractions.
