| Summary: | Phytoremediation techniques have emerged as a promising approach for soil reclamation and remediation of contaminated sites. This review article provides a comprehensive analysis of the different phytoremediation techniques used for soil reclamation and their effectiveness in removing contaminants from soil. The aim is to evaluate the current state of knowledge and to highlight potential avenues for future research in this field. The review begins with a discussion of the principles underlying phytoremediation, emphasizing the ability of plants to accumulate, tolerate, and detoxify contaminants through various mechanisms such as phytoaccumulation, rhizo-degradation, and rhizo-filtration. Different plant species and their suitability for phytoremediation are reviewed, considering factors such as metal tolerance, biomass production, and pollutant uptake efficiency. In addition, the role of soil amendments and their impact on improving phytoremediation efficiency is critically evaluated. Commonly used amendments, including chelating agents, organic matter, and pH adjusters, are reviewed with emphasis on their ability to increase metal bioavailability and plant uptake. The review also addresses challenges associated with phytoremediation, such as plant growth limitations, long-term sustainability, and potential risks associated with the release of pollutants into the atmosphere during biomass disposal. Strategies to mitigate these challenges, including plant breeding and genetic engineering, are discussed.
