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.

Vegetation is the plant cover of the Earth and comprises all plant species growing in a very great diversity of assemblages. 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 plant also evaluates its potential, in order to know the toxicity of the soil contaminated with the mineral. 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). 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. Bioaccumulation of trace metals in plant foliage and branch tips presents a health risk to wildlife, and potentially to humans. Pollution by metal is one of the most important global issues that are of concern to the environment and food safety. The consumption of food contaminated with toxic elements leads to the absorption of these toxins by humans. The higher the consumption of these substances, the greater the potential risk. Consumed by humans to affect the motor and mental functions of humans, and cause the possibility of causing blood and cause dysfunction in the functions of human organs such as lungs, liver and kidney. It is known that all minerals have unique features that vary from one substance to another and chemical and physical properties, some of which may have specific toxicity.
