The Phytoremediation of Fennel for Cleaning-Up Contaminated Soil

Phytoremediation uses plants to remove pollutants from the environment. The use of metal-accumulating plants to clean soil and water contaminated with toxic metals is the most rapidly developing component of this environmentally friendly and cost-effective technology. The present study was undertaken in view of providing an impeccable hypothesis that Foeniculum vulgare (from Apiacea Family,commen name is Fennel) may probably be employed as a potent phytoremediation of heavy metals : Lead , Cadmium , Nickel and Chromium from polluted soils.Results indicated that the rate of heavy metals uptake by this plant is Significantly affected by the PH of soil (p<0.01).Translocation factor for Lead and Nickel in all conditions were higher than one which indicates that metal concentrations in shoots were higher than roots and the plant is suitable for phytoremediation. The results of this research concluded that Fennel in the contaminated soil had suitable ability for phytoremediation by phytoextraction method and transmitting more Lead and Nickel in PH<7 after 35-45 days of growth of Foeniculum vulgare spices
