In the early 1980s, forest decline became a matter of public and scientific concern when forest stands with Norway spruce (Picea abies [L. ] Karst. ) showed evident damage on a large geographical scale throughout Europe. The causes of the observed symptoms could not be elucidated on the basis of the state of knowledge at that time. Therefore, several research projects were launched both in Germany and in some other countries in order to identify the relevant pathogenic factors. In 1985, the Federal Ministry for Research and Technology decided to include the site "Postturm", forest district Farchau/Ratzeburg, in the spon sorship of the research on forest decline as a site typical for lowlands and a sphere of anthropogenic urban influence. The investigation area is situated about 40 krn east-northeast of the city of Hamburg. Since spruce trees in particular showed severe decline, emphasis was laid on this species. The programme started in 1986 and extended to 1992, with some activities con tinuing beyond this time. Working groups from 13 institutions took part in the overall project.
X-ray fluorescence spectrometry (XRF) is a well-established analytical technique for qualitative and quantitative elemental analysis of a wide variety of routine quality control and research samples. Among its many desirable features, it delivers true multi-element character analysis, acceptable speed and economy, easy of automation, and the capacity to analyze solid samples. This remarkable contribution to this field provides a comprehensive and up-to-date account of basic principles, recent developments, instrumentation, sample preparation procedures, and applications of XRF analysis. If you are a professional in materials science, analytic chemistry, or physics, you will benefit from not only the review of basics, but also the newly developed technologies with XRF. Those recent technological advances, including the design of low-power micro- focus tubes and novel X-ray optics and detectors, have made it possible to extend XRF to the analysis of low-Z elements and to obtain 2D or 3D information on a micrometer-scale. And, the recent development and commercialization of bench top and portable instrumentation, offering extreme simplicity of operation in a low-cost design, have extended the applications of XRF to many more analytical problems.
Die zunehmende klinische Bedeutung der essentiellen Spurenelemente und Mineralstoffe war Gegenstand der 23. Tagung der Gesellschaft für Mineralstoffe und Spurenelemente e.V. in Stuttgart. Neben den Spurenelementen Antimon, Jod und Cadmium lag der Schwerpunkt auf Selen. Die Ergebnisse klinischer Studien zeigen die Anwendbarkeit zur Mortalitätsreduktion bei Sepsis, zur Reduktion von Nebenwirkungen der Strahlentherapie von Patienten mit Cervix- oder Corpus uteri-Karzinomen, zur Abnahme von Autoimmunantikörpern und Verbesserung klinischer Beschwerden bei entzündlichen Autoimmunkrankheiten der Schilddrüse wie Hashimoto- Thyreoiditis, zum Rückgang des Weichteilödems bei Patienten mit postradiogenen oder postoperativen Ödemen im Bereich der Mundhöhle. Ein lesenswertes wissenschaftliches update der Mineralstoffe und Spurenelemente, das sich durch die große Zahl der Beiträge unterschiedlicher Autoren durch Lebendigkeit und Vielfalt auszeichnet.
The purpose of this volume is to emphasize the fact that biological trace element research is a multidisciplinary science which requires a prudent combination of biological insight and analytical awareness. The text frequently stresses that accurate measurements on biologically and analytically "valid" samples hold the key for success in future investigations. It reminds the analytical scientists and the life sciences researchers that their perceptions should extend beyond conventional limits - namely, the former as generators of data and the latter as interpreters of those findings. This book enables the reader to understand the intricacies of elemental composition studies in biological systems, and also provides a valuable source of information to biologists, biochemists, physicians, nutritionists and related scientific workers who intend to draw meaningful conclusions from the analytical findings.
