The presence of cyanide is a significant issue in industrial and municipal wastewater treatment and management, in remediation of former manufactured gas plant sites and aluminum production waste disposal sites, in treatment and management of residuals from hydrometallurgical gold mining, and in other industrial operations in which cyanide-bearing wastes were produced. The complexity of the chemistry and toxicology of cyanide and the risk it poses in different environmental contexts make its management and remediation extremely challenging. Cyanide in Water and Soil is the first book to present the state-of-the-art in managing cyanide across a wide range of industrial and environmental contexts. The book brings together current knowledge and information about cyanide release to and behavior in the environment, and explores how to control or remediate these releases. No other broad-based examination of this topic exists. Exploring the anthropogenic and natural sources of cyanide in the environment, the authors address the full range of issues pertaining to cyanide fate, transport, treatment, and toxicity in water and soil as well as approaches currently used in risk assessment and management. They have developed a careful balance of depth and scope of coverage, providing current references that help readers learn more about topics of particular interest. An array of technologies is available for the treatment of cyanide in surface water and groundwater, wastewaters, and contaminated soils and sludges. These technologies span the gamut of biological, chemical, electrolytic, physical, and thermal treatment processing. Presenting examples of applications of the technologies employed most commonly in municipal and industrial settings, the book is a useful reference tool for engineers, scientists, practitioners, and researchers in academia, industrial organizations, government, and engineering and science consulting firms.

Cyanide has been found in many sites targeted for long-term fed. cleanup activities. Many of the cyanides in soil and water come from industrial processes. Contents: (1) The examination, summary, and interpretation of available toxicologic info. and epidemiologic evaluations on cyanide to ascertain the levels of significant human exposure for the substance and the associated health effects; (2) A determination of whether adequate info. on the health effects of cyanide is available to determine levels of exposure that present a significant risk to human health of chronic health effects; and (3) Identification of toxicologic testing needed to identify the types or levels of exposure that may present significant risk of adverse health effects in humans.

Contaminated land assessment is one of the major current areas of analytical chemistry. This volume provides a one-stop source of reference, addressing all aspects of the analysis, from delivery of the samples to the laboratory to the presentation of the results to the clients.

Knowledge of the basic interactions that take place between geological materials and different substances is the first step in understanding the effects of adsorption and other interfacial processes on the quality of rocks and soils, and on driving these processes towards a beneficial or neutral result. Interfacial Chemistry of Rocks and Soils examines the different processes at solid and liquid interfaces of soil and rock, presenting a complete analysis that emphasizes the importance of chemical species on these interactions. This Second Edition features novel results in the field and expanded coverage of the kinetics of interfacial processes. New content includes models of heterogeneous isotope exchange, sorption isotherms for heterovalent cation exchange, as well as sorption of anions by chemically modified clays. Summarizing the results and knowledge of the authors’ research in this field over several decades, this volume: Explores the individual components of the studied systems: the solid, the solution, and the interface Discusses the characteristics and thermodynamics of the interface Profiles the most important analytical methods in the study of interfacial processes Demonstrates transformations initiated by interfacial processes Outlines avenues of treatment that may solve geological, soil science, and environmental problems Drawn chiefly from the authors’ years of research at the Imre Lajos Isotope Laboratory in the Department of Physical Chemistry at the University of Debrecen in Hungary, this book discusses chemical reactions on the surfaces/interfaces of soils and rocks; examines the role of these processes in environmental, colloid and geochemistry; and explores the effects on agricultural, environmental and industrial applications.

The basic and applied toxicology of cyanides and cyanogens has widespread commercial, occupational, environmental, clinical, forensic, military, and public health implications. This book provides a detailed and updated reference describing the properties, uses, general and human toxicology, clinical recognition, diagnosis and medical management, and countermeasures is therefore required in academic, medical, occupational, environmental, medico-legal, regulatory, emergency response, and military arenas. Edited by a world-renowned team of experts from academia, defense and industry, this book will be an invaluable reference for professionals, researchers and students in cyanide and cyanogens.
