This study investigated the geochemical and mineralogical characteristics combined with heavy elements concentrations of Cement kiln dust (CKD) in Ain Sukhna industrial area, North‐western part of the Gulf of Suez, Egypt and the influence of flash floods in its stability. Flooding severity is moderate with several water erosional processes. The CKD characterized by very poorly sorted/very fine‐sands to silt. CaO and SiO₂ are major components with enrichment of chloride/sulfate ions. High enrichment of Sr, Zn, Pb, Cd, Sb, and Se are related to variations in shale/limestone feeds during cement formation. The threshold effect level exceeds the standard value for Cd, Pb, and Zn at S3 that indicates adverse biological effects. Sylvite, calcite, and halite minerals were dominated. Three main principal components recognized the shale, calcium/magnesium carbonate dissolution, and the scavenging effect of sulfate for heavy elements. Monitoring the CKD leachability and proper management plans are prerequisite for environmental protection in the future.

埃及苏伊士湾西北部Ain Sukhna工业区的水泥窑粉尘洪水灾害评估和特征

这项研究调查了埃及苏伊士湾西北部的Ain Sukhna工业区的水泥窑粉尘（CKD）的地球化学和矿物学特征及其重元素浓度，以及山洪对其稳定性的影响。洪水严重程度中等，并伴有数个水蚀过程。CKD的特征是分类很差/非常细的沙要淤泥。CaO和SiO ₂是富含氯离子/硫酸根离子的主要成分。Sr，Zn，Pb，Cd，Sb和Se的高富集与水泥形成过程中页岩/石灰石给料的变化有关。阈值效应水平超过了S3处Cd，Pb和Zn的标准值，表明存在不利的生物学效应。白云母，方解石和盐岩矿物占主导地位。三个主要主要成分认识到页岩，碳酸钙/镁的溶解以及硫酸盐对重元素的清除作用。监测CKD的浸出能力和适当的管理计划是未来环境保护的先决条件。
