Abstract:

Heavy metal contamination has increased rapidly since the early 20th century. A Large part of the world has been contaminated by organic and inorganic pollutants. Phytoremediation involves the use of plants to remove, transfer, stabilize and/or degrade contaminants in soil, sediment, and water. This plant-based technology has gained acceptance in the past ten years as a cheap, efficient and environmentally friendly technology especially for removing toxic metals. Currently, 6-8 billion US dollars are spent annually for environmental cleanup alone in the United States and worldwide it is 25-50 billion US dollars per year. Sebera acuminate and Thlaspi caerulescens (Cunningham and Ow 1996), Arabidopsis thaliana (Delhaize 1996), Typha latifolia, and Phragmites australis (Ye et al., 2001) are some identified plants which are known for heavy metals accumulation in their tissues. In zinc and lead mine’s Typha latifolia and Phragmites australis have been successfully used for phytoremediation in China. Water hyacinth (Eichhornia crassipes, Kay et al., 1984; Zhu et al., 1999), pennywort (Hydrocotyle umbellata L., Dierberg et al., 1987), and duckweed (Lemna minor L., Mo et al., 1989) are some important aquatic species known for the remediation of aquatic ecosystem. Further explorations are needed in the field of Phytoremediation to address technical issues and to find out the geographically suitable plant species for effective phytoremediation. Accumulation of heavy metals by plants is affected by many factors, variations in plant species, plants growth stage and element characteristics control absorption, accumulation and translocation of metals.
