Arsenic

Environmental Chemistry, Health Threats and Waste Treatment

• Gebundenes Buch

Produktbeschreibung

This book presents an overview of the chemistry, geology, toxicology and environmental impacts of arsenic, presenting information on relatively common arsenic minerals and their key properties. In addition, it includes discussions on the environmental impacts of the release of arsenic from mining and coal combustion. Although the environmental regulations of different nations vary and change over time, prominent International, North American, and European guidelines and regulations on arsenic will be reviewed. Includes information on recent environmental catastrophes (e.g. Bangladesh and China)A thorough discussion of the arsenic cycle, including the cosmological origin of arsenicIncludes Appendices providing extensive glossary and measurement conversion tables

Autorenporträt

Kevin Henke is a research scientist at the Centre for Applied Energy Research at the University of Kentucky. He has a M.S. and? Ph.D. in Geology from the University of North Dakota. His research includes investigating water and air quality issues related to coal combustion, studying the impact of mercury and other heavy metals on water quality, and investigating the leaching of inorganics from coal combustion by-products. He is also visiting Assistant Professor of Geology, Department of Geological Sciences, University of Kentucky, Lexington (1998, 2000-2002) and has taught geochemistry, mineralogy, teaching methods courses, and undergraduate introductory courses in environmental geology, natural resources and physical geology. Professor David A. Atwood, is based in the Chemistry Department of the University of Kentucky. He obtained his B.S. from the University of Alabama and his Ph.D. from the University of Texas in 1992. Research in the Atwood group is designed to address both fundamental and applied aspects of the main group metals.
