Description
Summary:Background: From the global point of view, the soil is considered as the third major component of the environment, and its pollution is currently one of the most important challenges for environmental organizations worldwide, as well as the most significant environmental problems for countries. Therefore, the present study aims to comprehensively investigate the mechanisms of phytoremediation as an effective and sustainable tool for the purification of various pollutants from the soil. Materials and Methods: This study was a descriptive review conducted in 2024 to report the process of search, documentation, and screening of the PRISMA checklist for systematic reviews. The search method included articles from 2000 to 2023 using the English keywords Phytoremediation, bioremediation, soil contamination, Heavy metals in soil, and their corresponding Persian equivalents on reputable websites such as PubMed, Scopus, Web of Science, Google Scholar, Magiran, and SID. Results: After searching with relevant keywords, a total of 1021 studies were found, and based on the criteria of input and output, 50 articles were used. According to the results, the main pollutants in soil are heavy metals, BTEX pollutants, and petroleum substances, which can be effectively remediated through various phytoremediation mechanisms, including hydraulic control, phytodegradation, phytoextraction, phytostabilization, phytovolatilization, rhizosphere degradation, and rhizofiltration, as a novel technology for addressing these contaminations. Conclusion: The high costs of physical and chemical methods of soil remediation have led to the utilization of phytoremediation as a more cost-effective and simple approach for soil purification. The main advantage of this method over others is its affordability and simplicity, while its disadvantages include the potential accumulation of metals in bioaccumulating plants and the consumption of contaminated plant biomass by animals, limited climatic conditions, incomplete understanding of this technology, and its lengthy duration.
