Harnessing Hyperaccumulator Plants to Phytoremediate Contaminated Mining Sites
Over the past 20 to 25 years, hundreds of plant species have been used to remove contaminants from soil and water. Hyperaccumulator (HA) plants can take up huge amounts of metals in their shoots without showing any toxicity impacts on the plants. For metals, these plants are capable of accumulating metals above the threshold concentrations of 10,000 mg/kg dry weight of shoots for Zn and Mn, 1,000 mg/kg for Co, Cu, Ni, As, and Se, and 100 mg/kg for Cd. Phytoremediation using HA plants is an exciting and promising biotechnology because of the following features: relatively inexpensive; considered an eco-friendly and sustainable technology; aesthetically pleasing; and ability to achieve complete breakdown of toxic materials. The objective of the workshop is to provide participants with the theory and practical skills on how to use phytoremediation to cleanup mining sites that are contaminated with metals.
