Abstract :
Purpose The investigation of the phytoextraction potential
of three vegetable plants grown in soils amended with
decanter cake.
Method Pot experiments were conducted to investigate the
response of decanter cake composition on the phytoextraction of metals (Mg, Zn, Ni and Cu) by lady’s finger,
tomato and brinjal plants. The phytoextraction properties of
these plants were determined by calculating the bioconcentration and translocation factors at different decanter
cake amendments (10, 20 and 30%).
Results Results indicated that in all three plants, there was
no transfer of excess metal ions from the control soil or
amendments to the fruit portion as evidenced by bioconcentration factor (BCF). In addition, substantial amount of
the metals was found to be accumulated in the roots and
shoots, which depicts the phytoextraction ability of these
vegetable plants. The translocation factors (TF) of the three
plants were found to be higher than control plants. The
accumulation of metal ions did not exceed the permissible
standards for vegetables thus rendering the fruits safe for
human consumption.
Conclusion On the basis of significant findings, lady’s
finger, tomato and brinjal plants were not found to be
suitable for phytoextraction of metals as both BCF and TF
were not greater than 1.
