Soil is the basic environmental element constituting ecosystem and a crucial component for existence and growth of all living things. Heavy metals are one of the dangerous elements found in soil that could be damaging the plants, animals and people. Heavy metals present in food can result in a number of dangerous illnesses that can be fatal and destructive. Metals, in contrast to organic molecules, are difficult to breakdown and clean up. To remove heavy metal contamination from soil, a variety of remediation techniques are available, including physical, chemical and biological techniques. Biological approaches are currently very effective and have numerous benefits, but physical and chemical procedures still have many drawbacks and negative effects. One of the biological methods is Phytoremediation. It is the most effective and distinctive way to remove metal contamination. It is a green technology that has favourable public opinion. The status of phytoremediation technology, with a focus on soil heavy metal contamination and its treatment methods like phytostabilization, phytoextraction, Phytovolatilization and phytofilteration processes etc are dealt in this chapter. To improve the scope of employment of this technology in the near future a greater understanding of phytoremediation potential is necessary.
