Abstract In this paper the authors analyse the trace elements in hair and liver of giant panda by PIXE and test the ratios of trace element contents in liver and hair to Zn separately. Trace elements in the foreleg hair and liver of epileptic and normal giant panda were measured by PIXE. Experimental results show that the K and Fe contents in the liver of diseased giant panda are very much higher than normal giant panda, but the Ca and Cu contents of the latter are significantly higher than the former. The K, Ca, Zn contents in the hair of diseased giant panda are very much higher than normal giant panda, whereas the Fe content of the latter is significantly higher than the former. However the Mn and Zn contents in the liver, the Mn and Cu contents in the hair of the diseased panda do not differ from the normal animal.
