There is increasing evidence that even minute amounts of trace elements can have profound effects on the human body. Advances in Isotope Methods for the Analysis of Trace Elements in Man describes new methods that are being developed to understand normal and abnormal trace element nutrition and metabolism.

This book includes a wealth of practical advice, encompassing all aspects of isotope methodology, such as the latest developments of analysis techniques for both stable and radioactive isotopes, issues in study design, current cost of isotopes, and analysis. It provides both a historical review of what has been done in the past and details of current techniques and applications.

> This state-of-the-art collection from leading experts in the field from Europe and the United States makes a strong case for the practice and advancement of this critical health care tool.
