Phytoremediation, a Method for Treatment of Petroleum Hydrocarbon Contaminated Soils

Petroleum hydrocarbons mostly contaminate environment due to inherent ability, such as solubility, volatility, and their biodegradable, they also identified toxic for animal. The petroleum has been released from an underground tank or refinery will likely be found in soils and possibly also in shallow groundwater and air that threaten health of human and environment. So the removal of these compounds from environment is vital. The stability of these pollutants at the soil and gradually accumulating over time disrupt the normal function of the soil, such as reduced agricultural capability. Phytoremediation describes the treatment of environmental problems (bioremediation) through the use of plants that mitigate the environmental problem without the need to excavate the contaminant material and dispose of it elsewhere. Phytoremediation consists of mitigating pollutant concentrations in contaminated soils, water, or air, with plants able to reduce or eliminate metals, pesticides, solvents, crude oil and its derivatives. In this study Phytoremediation method for treatment of polluted soil with petroleum hydrocarbon has been evaluated as well as its performance and efficiency.
