| description | The pollution of heavy metals in aquatic
environments is a major concern for human beings. The present study
demonstrates the phytoremediation potential of the aquatic macrophyte Pistia stratiotes for removal of Cr, Pb
and Ni from simulated wastewater. Pistia
stratiotes was grown in Faculty of Science & Natural Resources (FSNR)
lake water and spiked with different concentrations of heavy metals at 1 mg/L,
2 mg/L and 3 mg/L of Cr, Pb and Ni, respectively. The experiment was conducted
within a 14-day period in laboratory conditions. The study investigated the
percentage of removal of heavy metals by P.
stratiotes as well as determining the distribution of heavy metal patterns
in plant tissues, the bioconcentration factor (BCF), translocation factor (TF)
and relative treatment efficiency index (RTEI). The results showed that P. stratiotes is efficient in removing
single Pb at 1 mg/L and 3 mg/L and single Cr at 1 mg/L, with a removal
efficiency of 99.31%, 79.86% and 76.25%, respectively. It was found that P. stratiotes managed to concentrate Pb
in its roots up to 15,000 mg/kg in plant tissue. Data on bioconcentration
factor (BCF) showed that P. stratiotes
managed to reach BCF values over 6,000 each for single chromium at 2 mg/L and
lead at both 2 mg/L and 3 mg/L. It was found that the plant can consistently
translocate nickel from the roots to the shoots, while chromium and lead tend
to concentrate in the root tissues. The results revealed that P. stratiotes uses rhizofiltration as
its phytoremediation uptake mechanism. This study helps significantly to
increase knowledge regarding the potential of P. stratiotes in the phytoremediation of heavy metal-polluted
wastewater. |
