Analysis of trace elements in food from high and low incidence districts of gastric carcinoma in Shandong province by PIXE
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
