Developments in Tomographic Methods for Biological Trace Element Research a biological specimen is briefly explained and applied by way of illustration to the analysis of gallstones. A system capable of carrying out studies of the binding site of .Se in different matrices using time differential perturbed angular correlation spectroscopy is also briefly described. Develo

Use of Total Reflection X-Ray Fluorescence Analysis in the Life Scienceshe sample excitated in total reflection geometry. Simultaneous detection of almost all chemical elements and lower limits of detection for medium Z elements in the range of a few hundred fg are achievable at optimized excitation conditions. Aqueous and acidic solutions are the preferred sample types

Radiotracer Method in the Study of Environmental Speciation and Migration of Contaminantsnt are briefly discussed. Several recent examples of use in the author’s laboratory are given: development of the separation method for methylmercury and inorganic mercury in hair, analysis of the speciation of cadmium in soil solutions, study of the interaction of .Cs and .Co with suspended sedimen
