Uneven weather patterns, rising sea levels and increase in global temperature are due to an increase in emissions harmful to the environment. This calls for technologies and strategies to be used as mitigation measures. To this, phytoremediation, with its different mechanisms, is one way in which we can reduce global emissions. It is a technology that uses different mechanisms for specific plants for the removal of specific pollutants. It is an efficient and environmental friendly process. Despite the limitations of its long development time, site specificity, and climate conditions dependent, this technology can be used to remove contaminants from soil, water and air. In addition, its efficiency can be further improved by certain aids or amendments such as natural, synthetic, microbial and genetically modified plants. This review aims to define the mechanisms and plants involved in phytoremediation while also describing the role of natural and synthetic amendments that can further improve the efficiency of phytoremediation.
