| Abstract: | The analysis method for the eight heavy metal suchaas Cu Pb ZnCd Fe Mn Ni and Co in atmospheric dustfall and the method of the interfe-rence of coexisting ion as analysing the heavy metals above,as well as the way for the interference of suppression were introduced in this paper.Threeconcentration conceptions to express the heavy metal quantity in atmosphericdustfall(volumetric concentration,heaviness concentration and metallicdustfull quantity)were offered and their different physical significance wereexplained. |
