Abstract: The theme of this study was to detect the impact of some different industrial wastewater on maize plants and some soil physical and chemical properties. To achieve these objectives, one industrial area was selected at Mostorod, Kalubia governorate, Egypt, where wastewater is loaded with high amounts of fine suspended matter accumulated on the soil surface layer and negatively affected soil properties according to chemical composition of suspended matter. The ceramic industrial wastewater loaded with clay minerals, mainly kaolinite, led to an increase in clay content. Plugging the conducting pores, increasing fine capillary pores, soil bulk density and penetration resistance. Subsequently, quickly drainable pores and saturated hydraulic conductivity (Ks) were decreased. Regarding the heavy metal (Cd, Ni, Co, and Pb) contents uptake by maize plants decreased with increase of the distance from pollution source. The roots had higher levels of heavy metal than shoots. The contents of heavy metal in both (shoots and roots) remained higher than the toxic levels, and consequently negatively affected food chain as well as human and animal health.
