| Abstract: | A method for measuring trace elements in food by PIXE technique is presented. Concentrations of trace elements in food from high incidence district of gastric carcinoma, Qixia county, and from low incidence district, Cangshan county, both in Shandong province, are determined. The t-test indicates that the concentrations of Sr, Ni, Cu, Mn and Fe in food from Qixia county are significantly higher than those from Cangshan county, but a converse result is obtained for Se. |
