Mobilization of different metals between Tamarix parts and their crystal salts - soil system at the banks of river Nile, Aswan, was studied. Tamarix top and subsoil samples near and far from the plant were collected from six different locations at the banks of river Nile. The bioavailability of metals in the soil samples was evaluated by determining their contents using extraction single-step. The results of soil extraction confirmed that, the occluded Fe/Mn oxide fraction was a dominant fraction for all measured metals compared with exchangeable phase. The total content of heavy metals was significantly higher in topsoil than in subsoil with very few exceptions in some sites. The ratio of heavy metal concentrations in topsoil to that in subsoil enhancement (RTE) varied at different extractant solutions.
