Abstract |
The influence of industrial activities (El-Tebeen soils) and sewage water (El-Gabal El-Asfar soils) as an environmental pollutants on the heavy metals status (content and distribution) was studied. Soil samples were collected from two sites, the first soil site is affected by sewage water as a source of irrigation 0, 30 and 70 years). While, the second one is affected by the industrial activities at distances of 200 and 500 m from the Iron Steel Factory, beside a normal soil (unpolluted). The soil samples were collected from the depths of 0-15, 15-30 and 30-60 cm and were subjected to chemically analyzed. The obtained results revealed that, the contents of total Zn, Mn, Cu, Pb, Ni and Cd showed the highest increases in the surface layers of soils irrigated with sewage water for 70 year and those located at a 200 m from industrial activities. Data obtained from the sequential analysis revealed that the bounded heavy metal fractions in surface layers could be arranged in the descending order of residual fraction>carbonate fraction>organic fraction>exchangeable fraction for the studied elements. In general, the statistical analysis revealed that there are a highly positive correlations (r) between the total content of Zn, Mn, Cu, Pb, Ni & Cd and each of fine sand, silt, clay and organic matter. Also, there were highly negative correlations (r) between total contents of the pervious metals and each of pH & coarse sand of the studied soils. On the other hand, the analysis of variance revealed that there was a significant decrease for total Zn, Mn, Cu, Pb, Ni and Cd with increasing the soil depth, as well as, a significant increase of these elements with increasing the period of irrigation with the sewage water (El-Gabal El-Asfar soils) and with decreasing the distance from the industrial activity (at El-Tebeen soils)
