A comprehensive study on native plant species for phytoremediation of heavy metals contamination in soil

Phytoremediation refers to the use of plants to remove or stabilize environmental contaminants in an environment. It is regarded as a highly effective and inexpensive method in countering heavy metal pollution. This paper examines the feasibility of using native plants in phytoremediation through the demonstration of their sensitivity, survivability, and tolerance towards the local environmental condition and their capability to accumulate and tolerate contaminants such as lead, cadmium, and arsenic. Native species have various advantages that include lesser upkeep requirements, improved ecosystem incorporation, and least invasive danger. The mechanisms involved in phytoremediation range from phytoextraction, Phyto stabilization, and rhizofiltration to the specific roles played by native plants in remediation processes of soil and water. Case studies are presented to demonstrate the successful use of native species at various contaminated sites. Challenges related to scalability and ecological risks are addressed. Emerging trends, including biochar amendments, genetic modification, and expanded applications into urban areas, suggest promising future directions.
