Objective To provide basis of reference values for relevant parameters of Chinese Reference Man. Methods Eighteen kinds of major organ or tissue samples

including muscle

rib

liver

and so on

were obtained from 4 areas （Hebei

Shanxi

Jiangsu

and Sichuan provinces） with different dietary patterns in China in autopsy of 16 healthy adult men

who had just encountered sudden deaths. At the same time

whole blood samples were collected from 10 volunteers living in each of these areas. The concentrations of 56 elements in these samples were detected by using Inductively Coupled Plasma Mass Spectrometry （ICP-MS）

Inductively Coupled Plasma Atomic Emission Spectrometry （ICP-AES）

and Graphite Furnace Atomic Absorption Spectrometry （GF-AAS） techniques. Based on obtained concentrations and reference values of these organ or tissue weights for Chinese Reference Man

the relative elemental burdens in these organs or tissues as well whole body were also estimated. Results The concentrations of 56 elements in 18 main organs or tissues were determined all together and their elemental organ or tissue and whole body burdens were estimated. Furthermore

the distributions of important elements for radiation protection in these organs or tissues were emphatically discussed. Conclusion By summing with past related results

the total results obtained from the series of research may provide more reliable and better representative basis of these reference values for Chinese Reference Man than before.
