Many anthropogenic activities could magnify the concentrations of nonessential heavy metals (HMs) in soil, which, in turns, enter into the food chain and cause damage to plant, animal, and/or human population. The soil remediation is done in many ways such as conventional ones (physical and chemical methods), which are very expensive and damage the natural environment, and phytoremediation, which is quite affordable and is a green approach as compared to the conventional methods. Various chelating agents (organic and synthetic) are also used as amendments in phytoremediation of heavy metal-contaminated soil, which are very useful too. Although the chemical-assisted phytoremediation is useful, it has many risks/drawbacks, e.g., low efficiency, leaching of HM-chelator complex into the soil, and accumulation of HMs in plant parts. The microbe-assisted phytoremediation is an emerging and better tool for phytoremediation. The risks associated with this method are negligible as compared to chemical-assisted phytoremediation, and it augments the biological system of plants while removing HM. Hence, microbe-assisted phytoremediation is a better tool for phytoremediation.
