Therefore, sensitive plants growing in sites with heavy metals exposure show altered metabolism, growth reduction, and reduced biomass production and reduced yield. Cultivation of crops on contaminated sites may result in both growth inhibition and tissue accumulation of heavy metals with resulting possible risks to humans health. However, a great deal of research in the past ten years indicates that certain plants have the genetic potential to remove many heavy metals from the soil.

In order to solve the environmental problems with heavy metals, they have to either be removed completely from the contaminated soil or to be reliably immobilized. The excessive uptake of these metals from the soil can create dual problem: the harvested crops so contaminated serve as a source of heavy metals in our food supply, and yields are reduced due to adverse effect on plant growth (Bala and Setia, 1990; Hall, 2002). They inhibit physiological and metabolic processes like photosynthesis by reducing the canopy chlorophyll content, thus affecting growth and productivity, ... Industrial and municipal wastewater contain less concentration of heavy metals but long term use of these wastewaters for irrigation purposes can affect the plant growth and restrict soil function.
