Abstract


To assess the effect of industrialization and urbanization on the contamination of water streams, soil and plant. We quantified the concentrations of trace metals (Cd, Cr, Cu, Co, Fe, Mn, Ni, Pb and Zn) in soil, vegetables and the water streams used for irrigation. In general, the concentration of metals in all water streams used for irrigation was within the permissible limits. While soil located near from industrial area of Helwan recorded high concentration values of metals than the permissible limits, especially soils irrigated from iron and steel discharge pipe. Also, the concentration of Mn, Zn, Cu, Cr and Pb in edible parts of plants grown were higher than the permissible limits. Therefore, CF values indicate that soils irrigated with effluents of iron and steel factory were highly contaminated with Mn, Zn, Cd and Pb. The values of PLI were found to be generally high (>1). These confirmed that long term uses of wastewater might be excess the accumulation amounts of heavy metals in the soil irrigated. In general, EF was proven that the contamination of different metals was attributed to the human activities rather than the earth crust.
