Effect of Soil Contamination with Different Levels Some heavy metals (Pb, Cd, Ni) on Content of Elements in white Radish and Carrots Plants


A pot experiment was carried out in a plastic house which belongs to soil and water resources Department , College of Agriculture, University of Baghdad, Al-Jadiriya campus, using Loam soil texture to evaluate efficiency of white radish and carrots plants contents of cadmium, lead, and nickel in their tissues and recognizing which most efficient in phytoremediation, besides evaluation is one of them is contamination of these plants with these elements depending on the value of concentration index according to the international parameters of pollution. Root and shoot samples were taken, to determine the concentrations of these element, bio concentration factor (BCF) and translocation factor (TF).The results showed that White radish was Superior than carrot increase of bio – concentration in shoot and root parts of plants (BCF) of Pb, Cd, Ni. TF represents the translocation of element from the root to the shoot system and it was high with Cd, Ni elements and this increase translocation of these elements from root to shoot indicates plants, while Pb movement was reduced compared with the other elements , concentrations of Pb, Cd and Ni in the shoot and root plants of white radish significantly higher than this Conant rations in carrot plants.
