study of soilpollutants inomdurman industrialarea, sudan, using x-ray fluorescence technique

in this work x-ray fluorescence (xrf) technique was used to evaluate the soil pollution withheavy metals for twenty four surface soil samples (0–10 cm in depth) from various locations to cover theindustrial area in omdurman city, sudan. concentrations of 10 elements cr, ni, cu, zn, zr, pb, rb, co, cd andas were determined. it was found that cr, cu and cd concentrations for almost all studied sites are greaterthan the normal values, while most the ni, zn, co, as and pb concentrations are lower than the normal values.some of the concentrations of as are greater than the normal values. the elemental concentrations werecompared with the normal values and other studies in different locations from the world. the correlationbetween elements appears that pollution inside the investigated area results from different sources ofcontamination present inside it. the results establish a database reference of radioactivity background levelsaround this region.
