Phytoremediation of Cadmium-Contaminated Soil

Cadmium is a toxic metal. Its accumulation is increasing with increasing urbanization and industrialization. Thus, there is a needed for the remediation of cadmium present in soil, water, and other natural resources. To address this issue, various techniques of remediation are performed among which phytoremediation is emerging as the best method. In this chapter, we have discussed about various conventional techniques for remediating cadmium-contaminated soils and the challenges associated with these techniques. The chapter explores the application of different remediation approaches, including electro-kinetic remediation, chemical elution, stabilization and solidification, and phytoremediation, with a focus on their efficiency and practicality. Additionally, it highlights the limitations and environmental implications of each method.
