Role of nuclear analytical probe techniques in biological trace-element research

Trace element speciation in food: State of the art of analytical techniques and methods*

Some elements in food are notoriously toxic, whereas others are considered essential for human health. Information on the exact chemical form in which an element is present in food is of paramount importance to determine the safety and nutritional quality of food. This critical review discusses the state of the art of analytical approaches to speciation of trace elements in food products. The t...

Application of Wavelength Dispersive X-Ray Spectroscopy in X-Ray Trace Element Analytical Techniques

International Union of Pure and Applied Chemistry Analytical Chemistry Division Commission on Radiochemistry and Nuclear Techniques* Isotopic and Nuclear Analytical Techniques in Biological Systems a Critical Survey

Covalent binding of chemicals or their metabolites to DNA is a critical event in the initiation of chemical carcinogenesis. Measurement of covalent DNA adducts in model and human systems has become an important tool in mutation and cancer research. The recently developed , highly sensitive 32P-postlabeling assay of DNA adducts and its applications are critically reviewed. Basic features of assa...

Background Subtraction for Trace-element Analysis – Analytical Comparison of Methods

For wavelength-dispersive fluorescence analysis, the background is a nonlinear function of 2θ, and a linear interpolation between two background angles gives an erroneously high estimate. This discussion systematically develops and compares interpolation methods analytically, to demonstrate their strengths, weaknesses, and correct use. The background can be estimated from measurement at a singl...
