Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
In order to demonstrate the seasonal variations and the vertical distribution behaviors of heavy metals Cd, Pb, Cr, Cu and Zn in the sediment of Poyang Lake, the climate changes were simulated through the sedimental core sample experiments in our laboratory. It was founded that: (1) the relation of heavy metals contents in sediment of Poyang Lake is in the order of Zn >; Cu ~ Pb >; Cr >; Cd, and the concentration of Cd is lower than that of the detection limit; (2) the concentrations of Cr and Zn in winter are higher than that in spring and autumn, which shows that the seasonal character is obvious; (3) the evaluation of environmental pollution through either the geo-accumulation index method or potential ecological risk index method shows that copper has a relatively strong pollution level in sediment of Poyang Lake, which should arouse the attention of departments concerned.
