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 this paper, soil collected from garden was cultured in thermostated incubator. Adding heavy metal elements to the soil and the effects of compound action of heavy metal lead (Pb), zinc (Zn) and cadmium (Cd) on soil enzymatic activities were studied. The results showed that single metal Pb and Cd can increase urease activity, but that of Zn inhibits its. Coexist Pb/Cd or coexist three metals in soil inhibited the urease activity, whereas coexist Pb/Zn and Zn/Cd promoted its. Single heavy metal Pb, Zn and Cd were all negative value, which indicated that single metal can inhibit catalase activity. Either coexist Pb/Cd, Pb/Zn or Zn/Cd in soil was increased the catalase activity, while coexist three metals in soil restraining its.
