The pollution of the environment by heavy metals is becoming a serious problem. Environmental pollution directly or indirectly influences the condition of atmosphere, biosphere, hydrosphere, pedosphere and lithosphere. Heavy metals that are present in environment are outcome from industrial, thermal, and nuclear pollution. Non-biodegradable, heavy metals persist in the environment and can become part of the food chain through plants. Examples of some of the heavy metals are Arsenic (As), Lead (Pb), Mercury (Hg) etc. It is already possible to clean up the environment from these kinds of contaminants, but most of the methods are costly and difficult to achieve optimal results. At present to overcome these times problems a newly developed plant mediated technology has been used known as Phytoremediation. In this context, several phytoremediation methods are currently being used to remove heavy metal pollutants from contaminated soil and water, this technology is eco-friendly and cost effective. Over 400 plant species are capable of remediating contaminated soil and water. Some phytoremediating plants are Brassica juncea, Brassica oleracea, Sedum alfredii, Thlaspi caerulescens, Ipomea, Arabidopsis thaliana, and Helianthus annuus etc.
