Phytoremediation potential and its methods- a review.

With the increase in the world's population and the subsequent increase in housing density, we are facing the problem of water, soil, and air pollution. On the other hand, the use of physical environmental purification methods is very expensive and can even cause environmental pollution. Phytoremediation is a cheap and accessible method that uses the potential of plants to remove or destroy dangerous contaminants from water, soil, and air. One of the major problems in Phytoremediation is that the process is time-consuming.  This can be overcome by adding compounds such as nanoparticles in order to increase the speed. Special care must be given to using the correct doses of nanoparticles because they pass through cells and biological membranes, which may cause contaminations. Therefore, the use of appropriate doses of nanoparticles will eventually accelerate the phytoremediation process. The purpose of this study is to assess the recent discoveries in the Phytoremediation process and its methods.
