Areas contaminated by heavy metals were identified in the El-Gharbia Governorate (District) of Egypt. Identification used remote sensing and Geographical Information Systems (GIS) as the main research tools. Digital Elevation Models (DEM), Landsat 8 and contour maps were used to map physiographic units. Nine soil profiles were sampled in different physiographic units in the study area. Geochemical analysis of the 33 soil samples was conducted using X-ray fluorescence spectrometry (XRF). Vanadium (V), nickel (Ni), chromium (Cr), copper (Cu) and zinc (Zn) concentrations were measured. V, Ni and Cr concentrations exceeded recommended safety values in all horizons of the soil profiles, while Cu had a variable distribution. Zn concentrations slightly exceeded recommended concentration limits. Concentrations were mapped in each physiographic unit using the inverse distance weighted (IDW) function of Arc-GIS 10.1 software. Pollution levels were closely associated with industry and urban areas.

在埃及的埃尔-加比亚省（区）确定了被重金属污染的区域。鉴定使用遥感和地理信息系统（GIS）作为主要研究工具。使用数字高程模型（DEM），Landsat 8和等高线图来绘制生理单位。在研究区域的不同地貌单位中对九种土壤剖面进行了采样。使用X射线荧光光谱法（XRF）对33个土壤样品进行了地球化学分析。测量了钒（V），镍（Ni），铬（Cr），铜（Cu）和锌（Zn）的浓度。在土壤剖面的所有范围内，V，Ni和Cr的浓度均超过建议的安全值，而Cu的分布却可变。锌浓度略高于建议的浓度限值。使用Arc-GIS 10.1软件的反距离加权（IDW）功能在每个生理单位中绘制浓度分布图。污染水平与工业和城市地区密切相关。
