A method of trace element analysis by ICP-AES

in

serum from animals fed with irradiated food is described. In order to demonstrate that irradiated food is suitable for human consumption

it is necessary to perform an experiment of animal feeding with these food before use for human. Trace element analysis in animal serum could provide an actual evidence for further humen consumption study.

53 serum samples of the rats fed with irradiated food were obtained. After ashed and solved

ICP-AES analysis has been used for determining 20 trace elements in specimen solution. The detection limitations are in the range of 10

ppm for different elements. The recoverys of elements are from 70.08% to 98.28%. The relative standard deviations are found to be 0.71% to 11.52%.
