Abstract

A pot experiment was made to study the use of Phragmites australis to absorb and accumulate of Ni, Cd and Pb from enriched water with a formenied heavy metals, where Phragmites australis (common reed) plant was growing. The soil used was calcareous in nature which irrigated with such waters up to 120 days. Plant samples (shoots and roots) were taken after 40, 80 and 120 days from transplanting which put to heavy metals content. Obtained results showed that Eh values of the soil-water system affected the accumulation of the three studied metals in plant (shoots and roots), in turn, mainly due to the change of soil pH under such redox conditions. The overall results showed that all studied heavy metal uptakes increased with increasing metal concentrations of artificial heavy metal polluted water comparing to the control treatment. It is worth to mention that, roots tend to accumulate higher amounts of metal content than those of shoots. ANOVA results showed that the studied heavy metal concentrations in artificial polluted water and their interactions with both (roots and shoots) of the plant affected only Ni uptake by common reed plant after 120 days. In most cases metal translocation into common reed upper plant (shoots) showed no affect by increasing heavy metal concentrations in polluted water except for Cd and Ni after 40 and 120 days from transplanting, respectively where the metal concentration affect the translocation processes as it increases with increasing metal concentrations.
