DETERMINATION OF SOME HEAVY METALS POLLUTANTS IN SOIL SAMPLES COLLECTED FROM ATBARA CITY-SUDAN.

The present study was conducted to evaluate the pollution level by some heavy metals in four sites at Atbara city, Sudan, include Atbara Railway Station (ARS), Atbara Railway Workshop (ARW), Atbara Industrial Area (AIA) and Eldaman Complex Foundry (ECF). Soil samples were collected from the study areas and from area which is expected to be free from industrial emissionto serve as control.Samples were analyzed for heavy metals (Fe, Cu, Mn, Cr, Ni, Pb, Zn and V) by using x-ray Fluorescence. The data were treated statistically by correlation coefficient and multivariate analysis such as cluster analysis.The results indicated that the mean concentration of these metals in all areas of the study were higher than in the control area except Fe,this refer to anthropogenic activities for all areas. Also the results showed that metals (Pb, Zn, Cr, Ni, V,Mn and Cu) were derived from anthropogenic sources, (V, Mn and Cu) as originating from mixed (anthropogenic and natural) sources and Fe from natural source. Fe,Cu, Mn ,Cr, Ni, Pb,Zn and V were determined by using X-MET5000.The data were treated statisticallyby correlation coefficient analysis and multivariate analysis such as, cluster analysis. Strong correlation coefficient between Mn- Cr, Mn-V, Ni – V, Fe- Zn,Mn-PbandPb-Vwere observed. The hierarchical cluster analysis using nearest neighbor method produced two clusters. The first cluster contained (Pb ,Zn , Cr, Ni V,Mn and Cu), the second cluster was contained (Fe ,Mn ,Cu and V).The results of the present study were also compared with previous studies .
