Abstract: 13 elements (Pb, Zn, Cu, Cr, Ni, As, Fe, Ti, Mn, K, Ca, Rb and Sr) in the soils of some Japanese city parks were determined with powder pellets by XFR. The result showed that when the depths on soil section increase, the coneentrations of Pb and Zn decrease significantly and that there is also certain correlation between the concentrations of Pb and Zn. A new method for investigating soil pollution by heavy metals was researched.
