Comparison of extractability of Cd Cu Pb and Zn with . Among the extradants 1 M HCl extracted the largest proportion of Cd 79 to 96 of total Cu 61 to 83 Pb 51 to 99 and Zn 23 to 52 from soils followed by 0 1 M HCl NH 4 Cl DTPA and CaCl 2 In all the extradants the proportion of extractability of metals was higher in the contaminated soils than the non contaminated soils
The translocation factor revealed that E. acoroides is a hyperaccumulator plant as its blades can accumulate high concentrations of Cd Cu Ni and Zn but not Pb. The plant limits Pb mobility to minimize Pb s toxic impact. Thus E. acoroides is a potential bioindicator of metal pollution by Cd Cu Ni and Zn in estuarine environments.
