Study on the Accumulation Characteristics of Hyperaccumulator Phytolacca Acinosa Roxb on Heavy Metal Pb

Abstract:

To study and select the proper hyperaccumulator plants and their growing method for rapid and effective heavy metal contamination cleaning is of great significance for heavy metal contamination restoration and treatment. This research takes Phytolacca acinosa Roxb as experimental material with lead chloride (PbCl2) of various concentrations as different treatment factors, uses potting plant sto simulate natural environment polluted by heavy metal, analyzes the accumulation characteristics of Phytolacca acinosa Roxb on Heavy Metal Pb. The results show that as the concentration of PbCl2 increases, the accumulation of Pb in Phytolacca acinosa Roxb also increases; when the concentration of PbCl2 content reaches a maximum level of 200 mg/Kg, the Pb content of overground part shows a highest level of 1.763mg/g DW, while the Pb content of foot end part is 0.402 mg/gDW. The experiment indicates that accumulation amount of the overground part (S) to that of the foot end (R) is S/R >1, which shows the basic characteristics of Pb Hyperaccumulator.
