Environmental Aspects Of Trace Elements In Coal

Happy he who could learn the causes of things (Virgil, Georgics 11) There is clearly a place for a book on the environmental aspects of trace elements in coal, especially with the increasing use of coal for power production. Our aim is to provide relevant background information and to update the situation regarding trace elements during beneficiation, combustion, .atmospheric deposition, leaching from wastes anti reclamation. The outcome is a balanced account of the overall situation. The initial chapter gives the rationale behind the planning of the book and puts the topics into the context of trace elements in the environment, while the final chapter summarises the subject matter and conclusions of each chapter. The choice of authors was based on their specialised knowledge. Although every effort has been made to ensure uniformity in layout, use of units, references and the like, authors have been given some latitude in expression and their styles have not been curbed. This book is intended primarily for coal scientists and technologists involved in environmental aspects of trace elements during the mining of coal, its beneficiation and usage, especially for power generation, and for regulatory bodies. It is considered to be suitable for relevant postgraduate courses. Just as it has been said that one of Bruckner's symphonies has enough melodies for a Beethoven to have written ten symphonies, so this book has several chapters that could be themes for other books.

Trace Elements in Coal and Coal Combustion Residues focuses on trace metal chemistry of coal and coal combustion residues. Special emphasis is placed on management of coal combustion residues in electric power plants and the influence of coal and associated residues on soils, plants, water, and animals. Topics covered include a brief summary of research sponsored by Electric Power Research Institute, environmental pollution from coal combustion plants in low-rainfall regions, accumulation of trace elements in freshwater mussels near a power plant, testing to evaluate fossil fuel wastes by chemicals and isotopes, transport of metals from coal piles and ash impoundments, leachability and toxicity of metals in fly ash, and plant absorption of chemicals from ash. The book will be a useful reference for environmental and reclamation consultants, environmental engineers, toxicologists, environmental regulatory personnel, officials with electric power utilities and water treatment plants, and soil scientists.

Intended as a concise yet comprehensive reference for specialists. Encompasses all aspects of trace elements in coal, drawing on a wide array of scientific and industrial literature. Much of the information is from the past decade, reflecting the upsurge of interest in most countries where coal is produced or used, and the growing concern over the environmental aspects of the mining, treatment, and use of coal. Chapters cover the origins, modes of occurrence, methods of analysis, contents--including detailed information on nearly 50 specific elements, comparisons of coal with shale and oil, variations within seams, radioactivity, and the relevance of trace elements to marine, environmental, and health aspects. The introduction briefly surveys the literature, gives background information on coal areas, and explains geochemical cycling. No index. Annotation copyrighted by Book News, Inc., Portland, OR

The research papers in this book present current knowledge of the sources, pathways, behavior, and effects of trace elements in soils, waters, plants, and animals. It is of interest to a variety of readers, including public health and environmental professionals, consultants, and academicians.

The accumulation of large amounts of ash from fossil fuel combustion for electric power plant generation is becoming a major environmental concern in the United States. Furthermore, stringent environmental regulations mandated by the Environmental Protection Agency through the Clean Air Act, Clean Water Act, Resource Conservation and Recovery Act, as well as state and local environmental regulations may result in even more ash production with subsequent contact with the environment. The concentrations of trace elements in coal residues are extremely variable and depend on the composition of the original coal, conditions during combustion, the efficiency of emission control devices, storage and handling ofbyproducts, and climate. The research papers in this book were presented as a part of the Sixth International Conference on the Biogeochemistry of Trace Elements held at the University of Guelph, Ontario, Canada, from July 29-August 2, 2001. The purpose of this corit'erence was to present current knowledge on the source, pathways, behavior and effects of trace elements in soils, waters, plants and animals. In addition, the book also includes invited research papers from scientists who have done significant research in the area of coal and coal combustion byproducts. All the research papers presented herein have been subjected to peer review.
