Fundamental Aspects of Pollution Control and Environmental Science 1: Trace-Element Contamination of the Environment investigates the global biological consequences of dispersal of trace elements that are mined from localized limited deposits in the environment. It considers the problem of trace-element contamination of the biosphere as an environmental pollution and as part of the ecological crisis as a whole. Comprised of eight chapters, this volume begins with an overview of trace-element contaminants, such as lead, cadmium, and mercury. It then discusses factors affecting the trace-element composition of soils, including sulfur, lime, and fertilizers. It explains as well the trace-element contamination of the atmosphere and hydrosphere, the sources of trace-element contamination of soils, and the availability of trace elements in the soil. The consequences of trace-element contamination of the soil, including its effects on crops and animals, are also discussed. The book also provides ways to prevent dispersal of metals in the environment. This book will be an essential reading for undergraduates, law students, and those who are interested about environmental pollution caused by trace elements.

Trace elements occur naturally in soils and some are essential nutrients for plant growth as well as human and animal health. However, at elevated levels, all trace elements become potentially toxic. Anthropogenic input of trace elements into the natural environment therefore poses a range of ecological and health problems. As a result of their persistence and potential toxicity, trace elements continue to receive widespread scientific and legislative attention. Trace Elements in Soils reviews the latest research in the field, providing a comprehensive overview of the chemistry, analysis, fate and regulation of trace elements in soils, as well as remediation strategies for contaminated soil. The book is divided into four sections: • Basic principles, processes, sampling and analytical aspects: presents an overview including general soil chemistry, soil sampling, analysis, fractionation and speciation. • Long-term issues, impacts and predictive modelling: reviews major sources of metal inputs, the impact on soil ecology, trace element deficient soils and chemical speciation modelling. • Bioavailability, risk assessment and remediation: discusses bioavailability, regulatory limits and cleanup technology for contaminated soils including phytoremediation and trace element immobilization. • Characteristics and behaviour of individual elements Written as an authoritative guide for scientists working in soil science, geochemistry, environmental science and analytical chemistry, the book is also a valuable resource for professionals involved in land management, environmental planning, protection and regulation.

Diet and Health examines the many complex issues concerning diet and its role in increasing or decreasing the risk of chronic disease. It proposes dietary recommendations for reducing the risk of the major diseases and causes of death today: atherosclerotic cardiovascular diseases (including heart attack and stroke), cancer, high blood pressure, obesity, osteoporosis, diabetes mellitus, liver disease, and dental caries.

The occurrence of heavy metals in the environment, even in traces, represents a severe risk for the ecosystems and can be dangerous to human health. However, a better understanding of the main aspects involved is still needed to reduce its negative impact on the environment and health. This book covers the recent methods used for the evaluation of heavy metal pollution and the identification of its sources, descriptions of some of the processes involved in its mobility and transport, attempts to address health and environmental effects of heavy metals pollution, and presents alternative technologies for its removal and remediation from environmental samples. Therefore, this book is recommended for experts in the comprehensive management of metal contamination in different environmental compartments.

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.)

Trace metals occur as natural constituents of the earth's crust, and are ever present constituents of soils, natural waters and living matter. The biological significance of this disparate assemblage of elements has gradually been uncovered during the twentieth century; the resultant picture is one of ever-increasing complexity. Several of these elements have been demonstrated to be essential to the functions of living organisms, others appear to only interact with living matter in a toxic manner, whilst an ever-decreasing number do not fall conveniently into either category. When the interactions between trace metals and plants are considered, one must take full account of the known chemical properties of each element. Consideration must be given to differences in chemical reactivity, solubility and to interactions with other inorganic and organic molecules. A clear understanding of the basic chemical properties of an element of interest is an essential pre-requisite to any subsequent consideration of its biological significance. Due consideration to basic chemical considerations is a theme which runs through the collection of chapters in both volumes.
