Plants have the capacity to obtain necessary elements from environment as micronutrients. There are several metals like Zn, Cu, which are essential for plant growth and sustenance, however, elevated level of essential or non-essential metals can lead to toxicity and inhibition of growth in most of the plants ( Hall, 2002, Lasat, 2002 ).
