This book was released on 2012-12-06 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a great dispar.ity between the ability of the major industrial nations to produce and distribute chemicals and our ability to comprehend the nature and potential severity of unintended consequences for man, his life support systems and the environment generally. Furthermore, the gap between our ability to produce and distribute myriad chemicals and our ability to identify, understand or predict unfavorable environmental impacts may widen. As environmental scientists we are conscious of the interrelatedness, not only of environmental systems, but of nations as well. Materials are continually moved across boundaries by human as well as natural agencies. The extent, rate and nature of transfer for most pollutants is largely unknown. We can only guess which of the numerous chemicals produced are candidates for concern. More important still is our practical ignorance of the mechanisms of chronic effects upon natural systems and of the concentrations, combinations and circumstances that may lead to irreversibilities or to serious consequences for man. We know very little also regarding the potential for or the kinds of indirect effects that might occur. With respect to the environmentltself, we know little of its assimilative capacity with regard to widely dispersed pollutants and their transformation products. But what we do know is disquieting, and a much-improved system for the evaluation and management of toxic and hazardous chemicals is needed.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: M.J. Schwuger The Environmental Specimen Bank is a repository of representative environ mental specimens for safe long-term storage over decades and centuries without any chemical change in the constituents. It represents the modern form of a systematically designed collection which will permit comparative analyses and evaluations of chemicals in the future. The aims are: - the determination of selected chemical compounds at the time of storage, - comparative investigations with new methods for chemicals which, at the time of storage, could not be determined or were not recognized as important, - observation of trends in the environment using authentic material from the past and - documentation of long-term changes. Environmental specimen banking is thus suitable for identifying environmental changes and initiating necessary measures of remediation. It may be used to identify problems, study correlations between cause and effect and determine the effectiveness of legislative measures as well as to recommend the activities required. This is not only ecologically important, but also relevant for man, since he is the last member in the food chain and is therefore affected by all compartments of the environment. For this reason, two banking systems were established in Germany, one for environmental specimens (Jiilich), and the other for human specimens (Miinster).
