Determination of nine inorganic elements in human autopsy tissue.

A survey of nine elements of accepted clinical relevance has been performed on tissue sets comprising of kidney, liver, heart and muscle taken at autopsy from healthy individuals killed as the result of an accident. The concentrations are reported using tissue wet weight, dry weight and nitrogen content as frames of reference. This has allowed direct comparisons to be made with other studies without resort to the use of conversions, using average factors, between one frame of reference and another. Such conversions are shown to be unreliable and may generate spurious differences. The results obtained are largely consistent with those reported from studies in other parts of the world.
