Mavrodineanu and published by Forgotten Books. This book was released on 2017-11-19 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Procedures Used at the National Bureau of Standards to Determine Selected Trace Elements in Biological and Botanical Materials This publication contains a detailed description of the procedures used at nbs to determine twenty-five trace elements in biological and botanical matrices. They were used to determine the trace element content of spinach, orchard leaves, pine needles, tomato leaves, bovine liver, blood serum, etc. The dissemination of these procedures, and their careful use, should permit other analysts to perform measurements with an accuracy comparable to those obtained at nbs.

Download or read book Reference Materials for Chemical Analysis written by Markus Stoeppler and published by John Wiley & Sons. This book was released on 2008-07-11 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many academic references describing how RMs are made, but few that explain why they are used, how they should be used and what happens when they are not properly used. In order to fill this gap, the editors have taken the contributions of more than thirty RM practitioners to produce a highly readable text organized in nine chapters. Starting with an introduction to historical, theoretical and technical requirements, the book goes on to examine all aspects of RM production from planning, preparation through analysis to certification, reviews recent development areas, RMs for life analysis and some important general application fields, considers the proper usage of RMs, gives advice on availability and sources of information and lastly looks at future trends and needs for RMs. This book is intended to be a single point of information that both guides the reader through the use of RMs and serves as a primary reference source. It should be on the reading list of anyone working in an analytical laboratory and be found on the library shelf of all analytical chemical laboratories.

Available in PDF, EPUB and Kindle. Book excerpt: This handbook was prepared with the objective of improving the understanding of the basis for the use of Standard Reference Materials (SRMs). While written from the viewpoint of a chemist, the basic concepts described are believed to be applicable to most areas of metrology. The handbook is arranged by section in a logical progression, starting with the basic concepts of precision & accuracy, followed by discussions of the calibration & quality assurance of the measurement process, the use of SRMs to evaluate various kinds of measurements, & the reporting of data with evaluated limits of uncertainty. Charts & tables.

Download or read book Monitoring Environmental Materials and Specimen Banking written by N.P. Luepke and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever since the industrial revolution, large numbers of environmentally hazardous materials are in troduced into the global environment annually; a list of all substances which are at present re garded as environmentally hazardous might contain thousands of compounds, and new substan ces are still being added. Several major activities are necessary of adequately ensure the protec tion of human health and the environment from the often subtle effects of these materials. These activities include toxicological and ecological research, control technology development, the pro mulgation of regulatory guidelines and standards, and the monitoring of environmental materials and specimen banking. In the absence of effective monitoring environmental materials and spe cimen banking, the detection of serious environmental contamination from pollutants may occur only after critical damage has been done. Environmental problems are independent of national boundaries and international collaborative programmes should be encouraged. Sponsoring organisations and other international and national bodies should encourage monitoring and specimen bank programmes and develop harmonised sy stems for data acquisition and evaluation. An international pilot programme of monitoring and specimen banking is needed and is technically feasible. The conclusions and recommendations, for both implementation and research, should be of inte rest to other international and national bodies in addition to the three organisation sponsoring this International Workshop. Nevertheless this joint sponsorship should help to assure that the re sulting conclusions and recommendations will have a worldwide audience and that effective coor dination of existing programmes will be possible.

Available in PDF, EPUB and Kindle. Book excerpt: This definitive new book should appeal to everyone who produces, uses, or evaluates scientific data. Ensures accuracy and reliability. Dr. Taylor's book provides guidance for the development and implementation of a credible quality assurance program, plus it also provides chemists and clinical chemists, medical and chemical researchers, and all scientists and managers the ideal means to ensure accurate and reliable work. Chapters are presented in a logical progression, starting with the concept of quality assurance, principles of good measurement, principles of quality assurance, and evaluation of measurement quality. Each chapter has a degree of independence so that it may be consulted separately from the others.
Download or read book Effect of Heavy Metal Pollution on Plants written by N. W. Lepp and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace metals occur as natural constituents of the earth's crust, and are ever present constituents of soils, natural waters and living matter. The biological significance of this disparate assemblage of elements has gradually been uncovered during the twentieth century; the resultant picture is one of ever-increasing complexity. Several of these elements have been demonstrated to be essential to the functions of living organisms, others appear to only interact with living matter in a toxic manner, whilst an ever-decreasing number do not fall conveniently into either category. When the interactions between trace metals and plants are considered, one must take full account of the known chemical properties of each element. Consideration must be given to differences in chemical reactivity, solubility and to interactions with other inorganic and organic molecules. A clear understanding of the basic chemical properties of an element of interest is an essential pre-requisite to any subsequent consideration of its biological significance. Due consideration to basic chemical considerations is a theme which runs through the collection of chapters in both volumes.
