| Abstract | ||
| Attempt was carned out on an area located between Helwan City South of Cairo, along a distance of 20 km to define soil polluted as a result of industrial. Conphrna samples collected from Ten soil profiles were taken according the different morphological features. Physical, chemical, micromorphology and heavy metals, i.e. Fe, Mn, Zn, Cu, Pb & Cd were detennined in soils. Results reveal the extent of inorganic and organic pollution of the tested media. Concentration of contaminants varied according to several factors, major of which are distance from polluting source increases in the vicinity of either industrial complex or dwelling zones as well as carried by aqueous water current in the first instance and wind direction in the second. Seven soil sites out of the ten investigated were polluted as they contained above permissible limits of heavy metals. Three of those sites were seriously injured so that the growth of cultivated maize was very poor to the extent that such weak plants were burned and some areas laid bare. The results also Indicate that the Inorganic and organic pollution are the main factor for land degradation through their effect on productivity. Soil pollution affects soil morphology, physical, chemical, heavy metals and micromorphology of soil. The productivity of SOils around the industrial activities are reduced referred to the surface and subsurface layers which are compacted and cemented by heavy metals which clear from morphology and micromorphology, high concentrations of heavy metals which caused in toxicity of plant, and other waste products have toxicity for plant. | ||
