Bioremediation Potential of MTBE in Water Resources by Eucalyptus Globolus

Methyl Tertia Butyl Ether (MTBE) is an organic compound with widespread use in unleaded gasoline. Although use of MTBE had some environmental advantages, it was soon cleared that this compound has adverse effect on environment and human health. MTBE is highly soluble in water, it binds weakly to soil and doesnʹt readily biodegrade in the environments. However it is known as a contaminant in environment specially for groundwater resources. Different methods have been introduced for treatment of MTBE from groundwater. These methods are generally expensive and inefficient. Phytoremediation introduce as an effective and inexpensive technology for removal of MTBE from groundwater and soil. In this paper the ability of Eucaliptus globules for removal of MTBE from water has been investigated.The Transpiration Stream Concentration Factor (TSCF) was used for evaluation of the ability of this plant. The calculated value for TSCF was 0.79 so it can be concluded that MTBE can be absorbed by this plant.
