The above plant species were irrigated, in a continuous mode, with 10mg CrVI/L contaminated tap water. More than 90% of hexavalent chromium was reduced to trivalent chromium, from both plant species, as measured in the drainage water. Moreover, total chromium removal ranged from 54% (Phragmites) to 70% (Helianthus). After 90days, the total chromium content of the contaminated soil dropped from 70 to 32 and 34mg Cr/kgdry soil, for Helianthus and Phragmites, respectively. Helianthus accumulated higher amount of chromium in the roots (2,730mg Cr/kgdry tissue) as compared to 1,800mg Cr/kgdry tissue for Phragmites. Most of CrVI was reduced to CrIII in all plant tissues, with Phragmites showing lower affinity for CrVI reduction in the root tissues but higher chromium translocation potential from roots to stems, while Helianthus showed higher chromium translocation from roots to leaves. Toxicity effects, expressed as root growth rate inhibition, indicated that Phragmites were the most tolerant specie to chromium effects. Both plant species showed high potentialities to be used in phytoremediation installations for chromium removal.
