The research papers in this text were presented as part of the Fourth International Conference on the Biogeochemistry of Trace Elements. The purpose of the conference was to present late-20th century knowledge of the sources, pathways, behaviour and effects of trace elements in soils, waters, plants and animals. The book is intended for a variety of readers, including public health and environmental professionals, industrial hygienists, consultants, waste management professionals, and academics. It may also prove valuable to scientists conducting research on coal and coal combustion byproducts.

This title is aimed at a variety of readers, including public health and environmental professionals, industrial hygienists, environmental consultants, waste management professionals, and academicians. It may also prove valuable to scientists conducting research on coal and coal combustion byproducts. The research papers contained within 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 conference was to present knowledge on the source, pathways, behaviour 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 have been subjected to peer review.

New analytical techniques have enhanced current understanding of the behavior of trace and ultratrace elements in the biogeochemical cycling, chemical speciation, bioavailability, bioaccumulation, and as applied to the phytoremediation of contaminated soils. Addressing worldwide regulatory, scientific, and environmental issues, Trace Elements in the Environment explores these frontiers, including biotechnological aspects of metal-binding proteins and peptides and phytoremediation strategies using trees, grasses, crop plants, aquatics, and risks to ecological and human health. Discussing trace elements in the holistic environment, this book covers advances in state-of-the-art analytical techniques, molecular biotechology, and contemporary biotechnology that enhances knowledge of the behavior of trace elements in the biogeosphere and at the cellular and molecular level.The editors and their hand-picked panel of contributors provide authoritative coverage of trace elements in the environment. They highlight cutting-edge applications of emerging strategies and technologies to the problems of trace elements in the environment. The editors discuss emerging areas such as bacterial biosorption of trace elements, processes, and applications of electroremediation of heavy metals-contaminated soils, application of novel nanoporous sorbents for the removal of heavy metals, metalloids, and radionuclides. The book focuses on the effects of increasing levels of trace elements on ecological and human health, evaluates the effectiveness of methods of phytoremediation, and covers risk assessment, pathways, and trace element toxicity.Containing more than 150 illustrations, tables, photographs, and equations, the book's coverage spans the entire body of knowledge available about how and why plants interact with metals and other trace elements.

Coal Combustion Byproducts and Environmental Issues addresses the major implications and critical issues surrounding coal combustion products and their impact upon the environment. It provides essential information for scientists conducting research on coal and coal combustion products, but also serves as a valuable reference for a wide variety of researchers and other professionals in the energy industry and in the fields of public health, engineering, and environmental sciences. The ultimate goal of this volume is to benefit both our economy and our environment as humanity enters the second half of the fossil fuel era.

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.

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. The editors have arranged the articles systematically by topic, beginning with the introductory chapter entitled "The Production and Use of Coal Combustion Products" followed by the sections on Environmental Impacts of Coal Combustion Residues, Trace Elements in Fly Ashes, Transport and Leachability of Metals from Coal and Coal Ash Piles, and the Use of Coal Ash as Agricultural Soil Amendment.

Fur­ thermore, stringent environmental requirements mandated by the Environmental Pro­ tection Agency including 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.
