Pistia stratiotes efficiently removes cadmium (Cd) from water, even at higher concentrations, with most uptake occurring in the roots within the first 24 hours. This aquatic plant shows promise for phytoremediation applications.

Area of Science:

  • Environmental Science
  • Plant Biology
  • Bioremediation

Background:

  • Floating macrophytes are increasingly studied for their potential in removing heavy metals from aquatic ecosystems.
  • Cadmium (Cd) is a toxic heavy metal pollutant requiring effective remediation strategies.

Purpose of the Study:

  • To evaluate the cadmium (Cd) uptake capacity of four floating macrophytes.
  • To identify the most effective species for Cd phytoremediation, focusing on Pistia stratiotes.

Main Methods:

  • Outdoor experiments were conducted during the coldest period of the year.
  • Four floating macrophyte species (Salvinia herzogii, Pistia stratiotes, Hydromistia stolonifera, and Eichhornia crassipes) were exposed to varying Cd concentrations.
  • Cd removal efficiency, bioaccumulation, and toxicity symptoms in Pistia stratiotes were monitored over 31 days.

Main Results:

  • All tested species demonstrated high Cd uptake efficiency.
  • Pistia stratiotes exhibited superior performance and higher relative growth rates, making it the focus for further study.
  • Pistia stratiotes achieved significant Cd removal within the first 24 hours, with higher initial Cd concentrations leading to greater bioaccumulation, primarily in the roots.

Conclusions:

  • Pistia stratiotes is a highly effective macrophyte for cadmium phytoremediation.
  • Root sorption is the primary mechanism for rapid Cd uptake in Pistia stratiotes.
  • While toxicity symptoms appeared at higher Cd concentrations, Pistia stratiotes maintained its Cd removal capacity.
