Currently, phytoremediation is an effective and affordable technological solution used to extract or remove inactive metals and metal pollutants from contaminated soil and water. of heavy metal polluted soils. Heavy metal toxicity in plants depends on the bioavailability of these elements in soil solution, which is a function of pH, organic matter and cation exchange capacity of the soil. (Hawkes, 1997: Duffus, 2002) Heavy Metal Pollution A major feature of heavy metal is non-degradability and persistence in all parts of the Metallic mercury. Heavy metals, such as cadmium, copper, lead, chromium and mercury are major environmental pollutants, particularly in areas with high anthropogenic pressure. The effect of heavy metal toxicity on the growth of plants varies according to the particular heavy metal involved in the process. Many of them are also animated. Plants possess a range of potential cellular mechanisms that may be involved in the detoxification of heavy metals and thus tolerance to metal stress. It is important to note that certain plants are able to tolerate high concentration of heavy metals in their envi-ronment. Bioavailability of heavy metals in terrestrial ecosystems depends on their physico-chemical form (Blanco et al. Heavy metals, like Pb Storage in liver.
