Download or read book Effects of Sample Formulation on the Analysis of Heavy Metals by X Ray Fluorescence written by Sandra J. Steele and published by . This book was released on 1994 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: A key area of research in environmental studies is the identification and analysis of metals in soil. Methods of testing soil samples have, in the past, involved much time in the laboratory setting. This report describes the use of an x-ray fluorescence spectrometer (X-MET 840) that can be used in the field, and a method of creating standard samples for its calibration. The method was developed to decrease the time factor involved in calibrating the X-MET 840 and testing soil samples for heavy metal contaminants. Analysis by x-ray fluorescence has many advantages because of the ease of operation and portability of instrumentation. This report describes the effect of pelletizing samples upon reproducibility of analysis. X-ray fluorescence, Environmental, X- MET 840, Heavy metals.

Download or read book X Ray Fluorescence Spectrometry and Related Techniques written by Eva Margui and published by Momentum Press. This book was released on 2013-01-25 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Environmental Heavy Metal Pollution and Effects on Child Mental Development written by Lubomir I. Simeonov and published by Springer Science & Business Media. This book was released on 2010-11-19 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heavy metals can be emitted into environment by both natural and anthropogenic sources, mainly mining and industrial activity. Human exposure occurs through all environmental media. Infants are more susceptible to the adverse effects of exposure. Increasing attention is now being paid to the mental development of children exposed to heavy metals. The purpose of this book is to evaluate the existing knowledge on intellectual impairment in children exposed to heavy metals in their living environment and to identify the research needs in order to obtain a clearer picture of the situation in countries and regions at risk, in which the economy is closely related to metallurgy and heavy metals emission, and to recommend a strategy for human protection. In greater detail the main objectives could be formulated as follows: to review the principal sources of single, and complex mixtures of, heavy metal pollutants in the environment; to identify suitable methodology for chemical analyses in the environment and in humans; to evaluate the existing methods for measuring mental impairment, including their reliability and validity; to recommend a standard testing protocol to be used in future research; to assess the future role of environmental heavy metal pollution in countries and regions at risk and its effects on children’s neurological development; to recommend a prevention strategy for protecting children’s health and development.
Download or read book X Ray Fluorescence Spectrometry XRF in Geoarchaeology written by M. Steven Shackley and published by Springer Science & Business Media. This book was released on 2010-10-17 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 1960s, x-ray fluorescence spectrometry (XRF), both wavelength and energy-dispersive have served as the workhorse for non-destructive and destructive analyses of archaeological materials. Recently eclipsed by other instrumentation such as LA-ICP-MS, XRF remains the mainstay of non-destructive chemical analyses in archaeology, particularly for volcanic rocks, and most particularly for obsidian. In a world where heritage and repatriation issues drive archaeological method and theory, XRF remains an important tool for understanding the human past, and will remain so for decades to come. Currently, there is no comprehensive book in XRF applications in archaeology at a time when the applications of portable XRF and desktop XRF instrumentation are exploding particularly in anthropology and archaeology departments worldwide. The contributors to this volume are the experts in the field, and most are at the forefront of the newest applications of XRF to archaeological problems. It covers all relevant aspects of the field for those using the newest XRF technologies to deal with very current issues in archaeology.

Download or read book Heavy Metals in Soils and Plants written by Pushpika Freitas and published by Scitus Academics LLC. This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil, one of the most important natural resources, is becoming degraded due to anthropogenic activities such as mining, agricultural activities, sewage sludge, fossil fuel combustion, metallurgical and chemical industries and electronics. Soil is a crucial component of rural and urban environments, and in both places land management is the key to soil quality. This series of technical notes examines the urban activities that cause soil degradation, and the management practices that protect the functions urban societies demand from soil. This technical note focuses on heavy metal soil contamination. Mining, manufacturing, and the use of synthetic products e.g. pesticides, paints, batteries, industrial waste, and land application of industrial or domestic sludge can result in heavy metal contamination of urban and agricultural soils. Heavy metals also occur naturally, but rarely at toxic levels.

Download or read book Heavy Metals in the Aquatic Environment written by P. A. Krenkel and published by Elsevier. This book was released on 2013-10-22 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heavy Metals in the Aquatic Environment contains the proceedings of an international conference held in Nashville, Tennessee in December 1973. This conference is co-sponsored by the International Association on Water Pollution Research, the Sport Fishing Institute, the American Fishing Tackle Manufacturers Association, and Vanderbilt University's Department of Environmental and Water Resources Engineering. Contributors focus on the hazards posed by heavy metals present in the aquatic environment and how to control them. This text consists of 45 chapters divided into eight sections. This book assesses the environmental impact of heavy metals found in the aquatic environment; the economic impact of removing them from waste effluents; and the costs vs. benefits attained by their removal. The social costs are also evaluated. After an introduction to dose-response relationships resulting from human exposure to methylmercury compounds, the discussion turns to the toxicity of cadmium in relation to itai-itai disease; the effects of heavy metals on fish and aquatic organisms; and the analytical methods used for measuring concentrations of methylmercury and other heavy metals. The next sections explore the transport, distribution, and removal of heavy metals, along with regulations, standards, surveillance, and monitoring aimed at addressing the problem. This book will be of interest to planners and policymakers involved in water pollution control.
