Abstract

The high concentricity of heavy metals is noxious to soils, plants, and humans. The aim of this study is to investigate the distribution of heavy metals (Fe, Mn, Zn, Cu, Pb, Ni, Cd, and Cr) in the landforms of the El-Saff area, Egypt. Satellite images were used to produce the landform map, digital elevation model (DEM), and field data. Collected soil samples were analyzed, the obtained data were used to create the spatial distribution layers of heavy metals. Data indicated that the main landforms in the study area are the flood plain, piedmont, and valleys which covered 19.57, 45.43, and 8.27 % of the study area respectively. The data also showed that the concentrations of Mn, Pb, Cu, and Ni were high in the flood plain while Zn and Cd concentrations were higher in the desert fringes (i.e., piedmont and valleys). The assessment of heavy metals reveals that most of the elements are under the critical leaves in the studied landforms. The higher contaminations are associated with cultivated areas irrigated by sewage water.
