Evaluation of petroleum hydrocarbons uptake by Fetsuca and Geranium: A case study at gasoil station in Damavand, Iran

Derived compounds leakage of petroleum by pipelines, overflowing of reservoirs, carrier vehicles accident and petroleum depots that burned in wars are most siginificant sources of environmental pollution by petroleum hydrocarbonsThe fate of spilled petroleum after releasing to environment is very variable, and different factors for controlling the situation are effective. Physical and chemical properties of these compounds, rate of concentration variation related chemical reactions or microbial degradation, environmental conditions such as temperature, light, oxygen and solubility rate in water can be considered. Nowadays, applying methods in accordance with environmental criteria expanding vastly and one of well-studied technique for cleanup of petroleum compounds is utilization of native plants. In current study, uptake of total petroleum hydrocarbons (TPH) by Fetsuca and Geranium with aim of TPH reduction from gas oil polluted soil was evaluated. Results indicated that Fetscua is capable of TPH uptake. Moreover, TPH content in Fetsuca were more than Geranium. With respect to results of this study, both plants can be potential candidate for TPH uptake from soil, where rate of uptake by Fetsuca is higher than Geranium
