Abstract Electrical resistivity and self-potential are effective geophysical tools for monitoring the soil and groundwater pollution because they are accurate, rapid, costless and non-distractive techniques. Direct or indirect burying of the corpses into the soil is one of the main factors which pollute the soil and the groundwater after decomposition of the tissues and bones. Therefore, the main objective of this study are using these tools to evaluate the rate of soil and groundwater pollution due to burying the corpses in chipboard coffins at depths approximately 0.70–1.30 m (Christians burial method) and directly into the soil at depths about 1.5–1.8 m (Muslims burial method). Beside, assessing the contamination depths and flow paths of the groundwater investigated area. The study area was carefully chosen because of: 1- it contains two different burial methods, 2- presence of shallow groundwater aquifer, 3- the surface layer which contains the burial depth is porous and permeable, 4- the cemeteries are near enough to the population density and agricultural lands. The study area was divided to three main sites; site 1, site 2 and site 3 for Christian cemeteries, Muslims ones and control area that does not contains any cemeteries respectively. Five two-dimensional electrical resistivity tomography (ERT) profiles were surveyed and analyzed using RES2DINV software (two profiles on the site 1, two profiles on the site 2 and one profile on the site 3). 121 points of vertical electrical sounding (VES) at the same depth were collected and analyzed in 3D iso-resistivity map. Self-potential survey (SP) were performed on the same 121 points of VES stations for comparison where the data was contoured to build 3D iso-potential map. The geophysical results were correlated with the available borehole data. The results revealed presence of three resistivity zones of high resistivities (1000–3000 Ω m), moderate ones (50–1000 Ω m) and low ones (

使用地球物理方法研究人类埋葬技术对土壤和地下水的环境影响评估:以埃及索哈格的 geheina 墓地为例

摘要 电阻率和自电势是监测土壤和地下水污染的有效地球物理工具,因为它们是准确、快速、无成本和无干扰的技术。将尸体直接或间接埋入土壤中是组织和骨骼分解后污染土壤和地下水的主要因素之一。因此,本研究的主要目的是使用这些工具来评估将尸体埋入深度约 0.70-1.30 m 的刨花板棺材中(基督教埋葬方法)并直接埋入约 1.5 深度的土壤中的土壤和地下水污染率–1.8 m(穆斯林埋葬方法)。此外,评估地下水调查区的污染深度和流动路径。仔细选择研究区域是因为:1- 它包含两种不同的埋葬方法,2- 存在浅层地下水含水层,3- 包含埋藏深度的表层是多孔和可渗透的,4- 墓地足够接近人口密度和农田。研究区分为三个主要地点;地点1、地点2和地点3分别为基督教墓地、穆斯林墓地和不包含任何墓地的控制区。使用 RES2DINV 软件(站点 1 上的两个配置文件、站点 2 上的两个配置文件和站点 3 上的一个配置文件)调查和分析了五个二维电阻率断层扫描 (ERT) 配置文件。在 3D 等电阻率图中收集并分析了相同深度的 121 个垂直电测深 (VES) 点。对 VES 站的 121 个相同点进行了自电位测量 (SP) 以进行比较,其中数据被绘制以构建 3D 等电位图。地球物理结果与可用的钻孔数据相关联。结果显示存在高电阻率(1000-3000 Ω·m)、中等电阻率(50-1000 Ω·m)和低电阻率(
