| Abstract | ||||
| The black-sand deposits are widely distributed alongside the Mediterranean Sea coast from Abu-Quir in the west to Rafah city in the extreme east. It contains, minerals, which is considered as the main source of uranium, thorium, potassium and iron oxides as a heavy and / or radio elements. These elements may be transferred with irrigation water to the plant organ (s), or even prevented the adsorption of nutrients. To achieve this purpose, surface soil samples (0-30 cm.) and subsurface soil samples (30 - 60cm) were collected from eastern and western of Rosetta area., also Aerva plants samples (roots, stems, leaves and flowers) as a wild plant were collected from these areas to evaluate the object of this study..The results showed highest values of thorium, uranium, potassium and iron detected in soil and plant samples near Rosetta estuary at two sides (eastern and western). The available N. P. K. and Fe in western soil samples were higher than that obtained by eastern soil samples. The N. P. K. content of the plant organ (s) samples that grown at western side were higher than that found the eastern side. The highest thorium, uranium and iron content found in plant root and the least were in the leaves or flowers plants, at two Rosetta sides. Also, total uranium, thorium and iron content in western side were higher than eastern side soil samples. | ||||
