Abstract

In present study, the soil and water were analyzed for cadmium metal. Its concentration in soil and water was 0.21 ml/kg and 0.001 mg/l respectively. For phytoextraction experiment pots were arranged in different groups such as Group A, B, C, D, E and F. To the soil of group A pots no metal was added and concentration of 100,200,300,400 and 500 ppm cadmium was added to the soil of group B, C, D, E and F respectively. The seeds of maize were sown in pots and observed its germination. Seed germination in group A was 5 while in group B, C, D, E and F was 5, 4.66, 4.33, 3.66, and 2.33 respectively. Cadmium metal decreased the rate of germination.

The fresh and dry weigh of the plants were decreased with increase of cadmium concentration in the soil. The cadmium content in the root of group A was 5.263 mg/kg while that of group B, C, D, E and F was 19.47, 36.75, 42.36, 50.96 and 62.32mg/kg respectively. The concentration of cadmium metal found in the stem of group A plants was 1.64 mg/kg while in the stem group B, C, D, E and F was 4.4, 3.01, 1.66, 1.05 and 0.08 mg/kg respectively. The concentration of cadmium in the leaves of group A was 2.86 mg/kg while in group B, C, D, E and F was 7.08, 6.96, 5, 3.36, and 2.44 mg/kg respectively. Calculated bioconcentration and translocation factors of all groups showed that both of them of the plant for cadmium metal decreased due to increasing cadmium concentration in the soil.
