Phyto-remediation: An ecologically sound approach to revegetate heavy metal polluted land

Gayathri P.M*, Akshika Bhawariya, Rahul, Ravi Kumar and Shweta Singh

Phytoremediation, that employs hyper-accumulator plant species that are incredibly tolerant to Heavy Metals (HMs) present in the environment or soil, is a feasible and promising method for removing HMs from contaminated environments. This method uses green plants to eliminate, break down, or detoxify dangerous metals. The procedure is simple, efficient, and cost-effective, with widespread implementation on a big scale. Nowadays, phytoremediation is a highly effective approach but its efficacy is largely dependent on the choice of plant species. The purpose of this study is to acquire some information regarding the sources and effects of the heavy metals arsenic, lead, and mercury (As, Pb, and Hg). It also provides a thorough analysis of phytoremediation technology, covering heavy metal uptake mechanisms and a number of related research findings.
