Contamination of soil by heavy metals has become a significant global issue due to its direct impact on human health and the environment. Among the various methods of remediating soil contaminated with heavy metals, phytoremediation is a cost-effective and ecologically friendly technique. Phytoremediation is a green strategy to remove, modify, or extract metal pollutants from soil and water by plant species. In order to investigate the ability of the rice plant to remove heavy metals in soil, a review study was conducted on the phytoremediation of heavy metals by rice. The results indicated significant differences in the concentrations of heavy metals between the roots and shoots of rice. So that most metals absorbed by rice were accumulated in the roots, except for cadmium (Cd). The rice is considered to be the most suitable plant in fields contaminated with moderate Cd for extraction of this metal. According to this, the shoot accumulation of Cd in indica rice varieties was high, which indicates that these varieties would be most responsive to phytoremediation of paddy fields contaminated with Cd. In addition, based on the research results, it is possible to remove copper and zinc by rice from paddy soils with low to moderate contamination levels. Considering that rice plays an important role in the human diet, additional precautions are needed to prevent heavy metals from entering the food chain during phytoremediation by this plant.
