dc.description.abstract | Phytoremediation presents a low-carbon and eco-friendly solution for heavy metal-contaminated soils, which pose greathealth and environmental risks to humans and ecosystems. A hydroponic culture was used to quantitatively assess thephytoremediation potential of plant species to remediate As or Cd-contaminated soil in field application. This study examinedthe growth, uptake, and distribution of Cd in the roots and shoots of Phalaris arundinacea and Brassica juncea in hydroponicconditions with Cd concentrations ranging from 0 to 20 mg/L for 10 days. Additionally, Aster koraiensis and Pteris multifidawere cultivated in hydroponic conditions containing As concentrations ranging from 0 to 40 mg/L for 10 days. Theconcentrations of Cd in the above-ground part and root tissues of P. arundinacea and B. juncea reached a maximum of 147.7and 1926.7 mg/kg-D.W.(Dry Weight), and 351.6 and 11305.5 mg/kg-D.W., respectively. Bioconcentration factor (BCF) for P. arundinacea and B. juncea were 68.9 and 122.3, respectively. Both species exhibited a translocation factor (TF) of less than0.1, indicating their eligibility for phytostabilization. Aster koraiensis exhibited significant As accumulation of 155.1 and1306.7 mg/kg D.W. in the above-ground part and root, respectively. However, this accumulation resulted with substantialweight loss and the manifestation of toxic symptoms. P. multifida exhibited higher accumulation of As (345.1 mg/kg-D.W.) in the fronds than in the roots (255.4 mg/kg-D.W.), corresponding to BCF values of 18.6 and 7.6, respectively, and aTF greater than 1.2. A TF value greater than 1.0 indicates that P. multifida is a viable option for phytoextraction. | - |
