In the present paper, the correlations between sixteen elements from the dry method roasted dust-slag of pyrite and sixteen elements from the soil layer near and far from the store area were studied by ICP-MS. Similar radio and outstanding different radio of the elements between the dust-slag and the soil were studied too. It was discovered that in the pollution soil layer Tl, Cd, Cs, Cu, Zn, Mn, Pb and Ni were easy to be identified and had similar radio with the elements in the dust-slag. But only Tl, Cd, Zn and Ni are suitable for criterion of element similar properties. In dust-slag and soil, distinct composition element radios of Tl, Cs, Co, Mo, Zn, Cr, V, Sr, Sb, Pb, Rb, Mn and Ni had striking differentiation. Only Tl, V, Sb and Cu corresponded to both the uncorrelated elements analysis of surface layer and middle-base layer soil. Tl could be used as an inspection target of similar elements and outstanding different elements between the dust-slag and the soil in the meanwhile. So we suggested that Tl can be used as a symbolic element in the roasting dust-slag of pyrite to find the dust-slag of pyrite in dust-recognition and to differentiate the metallurgy dust of pyrite and soil dust.
