This paper describes the proceedings of a workshop that was convened at the 11th International Symposium on Trace Elements in Man and Animals (TEMA-11) symposium to review recent advances concerning the assessment of the trace element status of individuals and populations, using zinc and copper as the primary examples to illustrate basic principles and recent advances in assessment methods. The workshop was initiated with a brief review of the importance of zinc nutriture for human health and a discussion of the likely common occurrence of zinc deficiency worldwide. This overview was followed by presentations on selected issues concerning the assessment of zinc status, with particular attention devoted to dietary assessment techniques, the use of isotopic tracers to assess zinc homeostasis and the relationship of these methods to biochemical indicators of zinc status. Because relatively little information is available on zinc toxicity, the discussion concerning the definition of excess intake of trace elements focused primarily on recent work concerning risk assessment of copper toxicity.
