In the study on the uptake of Nickel and Lead in Catharanthus roseus plants, it was found that the plant species has a higher accumulation of metals in the roots compared to stems and leaves. Over a period of 60 days, Nickel accumulation increased in all parts of the plant, with high accumulation observed after 40 days. The Bioconcentration Factor (BCF) and Translocation Factor (TF) values indicated that Catharanthus roseus is a good accumulator of lead and nickel, showing potential for phytoremediation and phytostabilization of heavy metal-contaminated environments.

Additionally, the study found that the uptake of Nickel and Lead in Catharanthus roseus plants was influenced by the concentration of the metals in the soil. Higher metal concentrations in the soil led to increased accumulation in the plant tissues. The roots of the plants served as the primary site for metal uptake, acting as a barrier to prevent excessive accumulation in the stems and leaves. The findings suggest that Catharanthus roseus has the potential to be used as a tool for remediation of heavy metal-contaminated soils. Further research is needed to explore the effectiveness of using this plant species in real-world applications for phytoremediation.
