Chromium


Book Description

Published in 1983: Chromium is important in medicine because of its widespread use (about 400,000 tons are processed in the U.S. each year), toxicity, carcinogenic effect, and its high sensitization index in low concentration.




Trace Elements in Clinical Medicine


Book Description

The Second Meeting of the International Society for Trace Element Research in Humans (ISTERH) was held in Tokyo from August 28 through September 1,1989. On August 27, the day preceding the opening of the meeting, a typhoon made a direct attack on Tokyo, welcoming guests from all over the world in a rather violent way. To our great relief, the weather during the week of the meeting turned out to be exceptionally agreeable for that time of year in Tokyo. We were also pleased to see the entire scheduled course of the meeting, including the social activities, carried out smoothly and the contents of the program favorably appraised. The meeting was attended by 518 scientists from 30 countries. Recent unrest following steps toward democratization in the Communist bloc gave rise to some apprehension; therefore, we were particularly pleased to see attendants from China, Eastern Europe, and the Soviet Union. No one could possibly have predicted the drastic change in Eastern Europe that followed, but again, we were relieved to learn (by a subsequent letter) of the safety of an attendant from Rumania, who had been our greatest concern. A total of 384 papers were contributed to the meeting. The abstracts for all have been published in the Journal of Trace Elements in Experimental Medicine, vol 2, No. 2/3 (1989). This proceedings carries 64 subjects introduced in the Special Session.




Element Analysis of Biological Samples


Book Description

Despite the development of innovative new analytical techniques for biological trace element research, today's trace element investigators face formidable obstacles to obtaining reliable data. This complete reference identifies and assesses the challenges the analyst encounters at each stage of an analysis, and discusses the effects of various techniques on the sample. Three internationally recognized scientists and authors consider the effects of the numerous collection, storage, and sample preparatory techniques used in sample analysis. Proper analytical quality control, including such critical factors as sampling and sample preparation, specimen preservation and storage, and ashing, is examined. The book also looks at sample preparation methods unique to various instruments and speciation chemistry issues, and examines the link between chemical analysis and specimen banking. A previously unrecognized source of error, presampling factors, is also discussed.







Trace Element Speciation Analytical Methods and Problems


Book Description

This book discusses in detail the application of physical separation procedures together with modern instrumental analysis techniques such as HPLC, gas chromatography, and anodic strip-ping voltammetry. Particular emphasis is given to environmental samples where the greatest concern for the effects of speciation on trace element transport, toxicity, and bioavailability have been ex-pressed. Special chapters are also devoted to methods of sam-pling and storage, and to the mathematical modeling of chemical speciation. Although designed for the practical analytical chemist, this publication is essential reading for researchers in or entering the field of chemical speciation.







Handbook on Metals in Clinical and Analytical Chemistry


Book Description

Describes general aspects of metals in clinical chemistry focusing not only on the physiology of metal ions and their analytical determination in biological materials, but also on their geochemical distribution, technical uses and environmental effects.
