Using rat liver as an example, the implications of postmortal changes such as cell swelling, imbibition and autolysis on the elemental composition of body organs were studied. Of the three elements investigated in this part of the experiment, concentration of Co increased from about +50 per cent to +120 per cent of control in all groups retained at room temperature and the content of Co rose by about 95 per cent; Cs increased less extensively than Co in all groups at room temperature; Se values showed up to 50 per cent increase in concentration only and there was no change in content. The changes were less marked for all the three elements at −15°C.
