I. INTRODUCTION
Even after a span of two decades and the considerable efforts expended to establish guidelines
to understand problems related to bioanalytical intricacies, there is still concern among trace
analysis researchers dealing with biological systems that analytical data obtained for organic
and inorganic constituents, especially for those at very low concentration levels, are inaccu¬
rate.1 11 Major efforts are therefore necessary to generate reproducible and reliable results,
e.g., to build up a reference data base for human tissues and body fluids. Unless this is
achieved, true variations in trace component concentrations arising from physiological
changes, pathological influences, and occupational and environmental exposures remain
submerged in the wide ranges associated with the reported analytical data. Unless sustainable
improvements are introduced in the working procedure, very little progress can be anticipated
in applying the results gained from such studies to practical problems in human health.
