Abstract

A pot experiment was carried out in Soil Dep., College of Agric. Mans. Univ., to study the effect of using sudan grass for remediation of some polluted soils in Dakahlia governorate .Ten plant seeds per pot were sown on 25August,2014 and harvested on 10 October,2014. The experimental soils were taken from ten polluted locations to represent polluted soils in Dakahlia govrnorate from different sources i.e. (sewage, industry, traffic and agricultural drainage pollutions) as follows: Talkha fertilizer company adjacent area; El-Mansoura Sewage Station area; El-Mansoura Melting companies area; Town refuse - Sandob area; El-Mansoura Ratingat factory; El-Serw station Agric. Drainage; Gedilah road near El-Mansoura Institute; Sewage drainage - Meet El-Akrad area ; Sallant- Dekrnes road and El-Sallab Institute area. Data obtained from this investigation pointed out that the concentration of lead, nickel and cadmium were (6.00, 3.43 and 3.39 mg/kg) in sudan grass plant shoots which uptake and removed high values of lead, nickel and cadmium (192,122 and 104 mg/kg plant) shoots of Sudan grass plant than the roots (2.16, 2.78 and 2.13 mg/kg) and roots uptake (7.0, 9.0 and 7.0 mg/kg plant) from the studied polluted soils. It can be observed that; shoots of sudan grass extracted and absorbed more lead, nickle and cadmium than roots because this plant has a huge vegetative growth. Results, also showed that; translocation factor (2.77, 1.41 and 1.56) and biological accumulation factor were more than one (0.66,0.78 and0.72) for laed, nickle and cadmium, respectively. It can be concluded that; Sudan grass is more effective for remediation of these polluted soils in Dakahlia government and can be considered as a hyper accumulator for heavy metals.
