Dr Charles Lee is the Program Convenor and Senior Lecturer at the University of Newcastle
(Australia), Singapore. He has more than 25 years’ experience in environmental research,
education and consulting in North America, and Asia-Pacific countries. He has soil science
degrees from the University of Guelph (BSc) and University of Hawaii (MSc and PhD). At
the Agency for Science Technology and Research, he was the lead co-author of a patent
for the photocatalytic degradation of halogenated compounds. Recently, he was invited as a
keynote speaker at the 7th International Cleanup conference, September 2017 (Melbourne,
Australia), and conducted a phytoremediation workshop at the Global Cleanup Congress, October 2018 (Coimbatore, India), both organized by CRC-CARE. He was also sponsored by the Chinese Research Academy of Environmental Sciences (Beijing, China) as a
remediation expert to conduct a workshop on “Risk-based Corrective Action and Bioremediation of Contaminated Sites”. Dr Lee is an associate editor of 3 research journals: International Journal of Environmental Pollution and Remediation (ASET, Canada), Environmental Geochemistry and Health (Springer, USA), and American Journal of Environmental Sciences (USA).
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.
