Abstract: The purpose of this study was to emphasize the Vegetation-enhanced bioremediation or phytoremediation plan for the surroundings of industrial area of Bhopal. This regions contain many industries and therefore there is a big risk of environmental pollution which is very hazardous to our health. Heavy metal accumulation in agricultural soils is potentially hazardous to human and livestock health. Excessive accumulations also present the risks of elevated heavy metal uptake by crops which could affect food quality and safety. Conventional remediation technologies are used to clean the vast majority of metal-polluted sites but they also tend to be clumsy, costly, and disruptive to the surrounding environment. In contrast, plants are known to sequester certain metal elements in their tissues and may prove useful in the removal of metals from contaminated soils. Over the past decade there has been increasing interest for the development of plant-based remediation technologies which have the potential to be low-cost, low-impact, visually benign, & environmentally sound, a concept called phytoremediation. Efforts should be made for dense vegetation of heavy metal bioaccumulation plants at the industrially contaminated sites. So that they reduce pollution and also give eco friendly aesthetic sense to enhance the beauty of the Bhopal city. Growing and, in some cases, harvesting plants on a contaminated site must be compulsory condition to setup or run a specific industry because this remediation method is an aesthetically pleasing, solar-energy driven, passive technique that can be used to clean up sites with shallow, low to moderate levels of contamination. This technique can be used along with or, in some cases, in place of mechanical cleanup methods. This paper attempted to provide a brief review on recent progresses in research and practical applications of phytoremediation for soil. Numerous plant species have been identified and tested for their traits in the uptake and accumulation of different heavy metals. Mechanisms of metal uptake at whole plant and cellular levels have been investigated. Progresses have been made in the mechanistic and practical application aspects of phytoremediation. They were reviewed and reported in this paper
