Abstract:
The concentrations of heavy elements was found by using x-ray fluorescence technique for wheat, degace from White Nile and Gazira and River Nile states, and for fiterita from white Nile state and Gazira state. The spectra of samples show high concentration of tungsten element in the range of (44.05 % - 36.09%) following by Ni in the range of (13.97%) beside the Mo in the range of (17.30% - 13.74%) in addition to Nb in the range of (13.74% - 14.78%). Then Fe in the range of (3.69% - 10.94%).
The tungsten clearly contaminate all corps. This element may result from the waste of yellow electric lamps, which are extensively used in houses.
