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.

Biogeochemistry of Trace Elements in Coal and Coal Combustion Byproducts

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.

Trace Elements in Coal and Coal Combustion Residues

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.

Chemistry of Trace Elements in Fly Ash

A topical selection of papers from a July-August 2001 conference in Ontario on the biogeochemistry of trace elements in general, has been augmented with contributions invited from researchers well versed in coal and the byproducts of its combustion. In the resulting 22 articles, scientists in the earth and environmental sciences, engineering, mathematics, and other disciplines from a number of countries consider the environmental impact of coal combustion residues, trace elements in fly ash, the transport and leachability of metals from coal and ash piles, and using coal as an agricultural soil amendment. Some of the chapters are double spaced. Annotation (c)2003 Book News, Inc., Portland, OR (booknews.com).
