Sedimentological and geochemical studies are integrated to determine the potential of heavy metals in the Middle Nile Delta soil. Four sources of trace elements were identified; a geogenic source includes Fe, Co, Cr, Ni and V, along with Ca that partly enhanced by anthropogenic input, and three dissimilar anthropogenic sources grouped the elements as follow; As, Pb, Zn Cu, Ba and P which derived mainly from industrial activities; Ba, Pb, Zn and Cu group is likely dispersed by traffic emissions, and P, As and Cu elements group which influenced by agrochemical application and drain water irrigation. The concentrations of studied elements increasing with decreasing the particle size. Moreover, two groups of mineral assemblages of soil are recognized; the first group deposited with one particle fraction and inherited from parent materials, The second one includes non-silicate minerals clasts, deposited with more than one fraction and most likely of anthropogenic source.

进行了沉积学和地球化学研究，以确定中尼罗河三角洲土壤中重金属的潜力。确定了痕量元素的四个来源。地源包括铁，钴，铬，镍和钒，以及由人为输入部分增加的钙，三种不同的人为源将元素分类如下：砷，铅，锌，铜，钡和磷主要来源于工业活动；Ba，Pb，Zn和Cu可能由于交通排放而分散，而P，As和Cu元素则受农药施用和排水灌溉的影响。所研究元素的浓度随着粒径的减小而增加。此外，人们认识到两组土壤的矿物组合。第一组沉积有一个粒子级分并继承自母体材料，
