The aquatic macrophyte, Potamogeton pusillus was evaluated for the removal of Cu2þ and Crþ6 from aqueous solutions during 15 days phytoextraction experiments. Results show that P. pusillus is capable of accumulating substantial amount of Cu and Cr from individual solutions (either Cu2þ or Crþ6 ). Significant correlations between metal removal and bioaccumulation were obtained. Roots and leaves accumulated the highest amount of Cu and Cr followed by stems. The bioaccumulation of Cr was significantly enhanced in the presence of Cu, showing a synergic effect on Crþ6 removal, presenting a good alternative for the removal of these metals from polluted aquifers. To the extent of our knowledge, this is the first report on both enhanced phytoextraction of Crþ6 in presence of Cuþ2 and bioaccumulation of these heavy metals by P. pusillus.
