Toxic Effect of Cadmium on Hydrocharis dubia root

Abstract:

After 4 days exposed to cadmium concentration environment, the soluble protein content, SOD activity, CAT activity, POD activity and MDA content of Hydrocharis Dubia root were investigated in this paper to study if this plant can be used to waterbody restoration with cadmium pollution. The result showed that when the cadmium concentration was lower than 5 mg.L-1, the plant didn’t encounter seriously oxidant damaged. The plant root cell increased SOD activity, CAT activity and POD activity to clean up these accumulated ROS. Hydrocharis Dubia can be used to waterbody restoration with lower than 5 mg.L-1 cadmium pollution. The plant unsuitable to be used to waterbody restoration with higher than 5 mg.L-1 cadmium pollution, the plant encountered seriously oxidant stress in this level cadmium pollution.
