It is hard to imagine a more concise summary of the prodigious work and voluminous publications in this field... This volume should be available to students at the undergraduate level, to those in law school, and to all seriously concerned about an extremely important problem. This review in Choice was just one of the many favourable comments that greeted the appearance of the first edition of this book when it appeared in 1977. Since then, there has been an explosion of interest in almost every aspect of research in environmental pollution. The aim of this new edition, however, remains the same i.e. to evaluate the global biological consequences of dispersal of trace elements, originally mined from localized limited deposits, in the environment. In treating the problems of metal contamination of the environment, the author considers the problems of environmental pollution involving metals and the problem of exhaustion of finite reserves of ores of metals, such as cadmium, copper, lead, mercury, nickel and zinc, as aspects of a single global problem. A broad picture is presented of the overall process of dispersal of trace elements in the environment and the biological consequences of this process are documented with the aid of an intensive list of references. The book will be invaluable as a definitive reference source covering this field of interest for a wide range of people (environmentalists and conservationists, those concerned with management of resources and waste disposal, and agricultural chemists and soil scientists.)
