The correlations of essential element Se between human hair and kidney-cortex, liver, and lung from the same subjects were investigated by instrumental neutron activation analysis, using the reaction76Se (n, γ)77mSe, for 24 Chinese autopsies. The concentration of Se is higher in kidney-cortex (2.04–5.36 mg/kg) than in liver (0.73–2.29), lung (0.50–1.85), and hair (0.37–1.43). It is important to know that there are significant relationships of Se concentration between hair and the other three internal organs. The correlation coefficient by linear regression analysis are 0.639, 0.570, and 0.635 for liver, lung, and kidney-cortex, respectively; and theP values are all less than 0.01 for the three tissues.
