Vegetation is the plant cover of the Earth and comprises all plant species growing in a very great diversity of assemblages.The physiological and environmental factors control the accumulation of minerals on the vegetation cover at a high rate, and human-induced activities have increased the stability of metals by plants.Also consider the types of plants that do not grow properly in contaminated soil, but tend to grow in the natural environment free of pollution in order to re-establish the self-sustaining vegetation with different plant species In contaminated areas (Peng, K., et al. 2006).It is also important to understand the absorption, transport and tolerability of the plant to transport polluting elements in the soil (Kent, M. 2011).The consumption of food contaminated with toxic elements leads to the absorption of these toxins by humans.
