Study of Some Heavy Metals and Radioactive Element from Soil Samples, Nyala Area -Sudan

In this work X-ray fluorescence (XRF) technique was used to evaluate the soil pollution with heavy metals for 40 surface and sub-surface soil samples (05 cm in depth) from various locations to cover the area of Nyala city, Sudan. Concentrations of eleven elements Cr, Ni, Cu, Zn, Pb, Co, Fe, Zr, Y, Rb and V were determined. The study established as the data baseline to the major and minor trace elements from study area that has not been investigated before. The elemental concentrations were compared with the normal values and other studies in different locations from the world. The correlation between elements indicates that no pollution exists inside the investigated area. The results indicated that all the samples analyzed are safe in general for the toxicity levels. The results establish a database reference of radioactivity background levels for the study around Nyala city.
