Bioremediation of Mercury: Current Research and Industrial Applications

Mercury is a heavy metal with extreme toxicity the ability to biomagnify and long range atmospheric transport of its gaseous form. Past and present industrial uses of mercury have resulted in the pollution of soils groundwater rivers and marine ecosystems worldwide - the clean-up of which using standard technology is either not feasible or is prohibitively costly. A low cost and environmentally friendly alternative is bioremediation: the use of microbes or plants (phytoremediation) to remediate contaminated sites. In this timely book established mercury experts review the latest research in this area including the genetic engineering of bacteria and plants. The gap between laboratory research and field application is bridged using the following case studies: an abandoned chlor-alkali electrolysis factory in Kazhakhstan a former PVC plant in Albania and the Madeira River Basin in the Amazon region. The remaining chapters cover: the mercury-cell process of the chlor-alkali electrolysis industry a pilot plant for wastewater bioremediation and a comparison of the efficiency of microbial bioremediation to clean-up three types of industrial wastewater. The book covers the complete range from laboratory scale research to full scale industrial operation and shows a multitude of options for future mercury bioremediation technologies. It will be essential reading for research scientists graduate students and other specialists interested in mercury bioremediation. It is also recommended reading for environmental microbiologists chemists and engineers.
