The phytoremediation potentiality of Cyperus articulatus naturally growing in industrial wastewater was tested. Nine heavy metals were selected for this purpose; As, Cd, Cr, Cu, Fe, Hg, Mn, Ni and Pb. Metal concentrations were measured using the atomic absorption. The accumulation rates of the studied heavy metals showed considerable variations in the accumulation abilities according to the plant organ and type of heavy metals. Accumulation of iron recorded maximum values ranged between (105.5 and 900 mu g/g d.wt.) in different plant organs of the studied species growing in wastewater, while minimum values were obtained for the accumulation of cadmium (0.9 to 1.95 mu g/g d.wt.). In general the studied heavy metal accumulation can be arranged as follows: Fe %26gt; Cr %26gt; Cu %26gt; As %26gt; Mn %26gt; Pb %26gt; Hg %26gt; Ni %26gt; Cd. The %26quot;translocation factor%26quot; (TF) and %26quot;bioconcentration factor%26quot; (BCF) were calculated. TF was found to be less than 1 for all metal cases, which confirmed the significance of below-ground biomass as a heavy metal accumulator. The HPLC technique was used to prove and assess the effect of heavy metal accumulation in the different plant organs on the chemical components especially in the bellow-ground parts. The obtained results support the idea of using the study plant for phytoremediation in industrial wastewater. [Hussein F. Farrag and Manal Fawzy.
