Trace Elements in Soils


Book Description

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.




Natural Attenuation of Trace Element Availability in Soils


Book Description

Understanding attenuation processes is important not only for predicting the behavior of contaminants in soil and formulating remediation strategies, but also for mitigating and enhancing the availability of micronutrients in soil for agricultural applications. Natural Attenuation of Trace Element Availability in Soils brings together pioneering re




Trace Element Contamination of the Environment


Book Description

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.




Soil and Water Quality


Book Description

How can the United States meet demands for agricultural production while solving the broader range of environmental problems attributed to farming practices? National policymakers who try to answer this question confront difficult trade-offs. This book offers four specific strategies that can serve as the basis for a national policy to protect soil and water quality while maintaining U.S. agricultural productivity and competitiveness. Timely and comprehensive, the volume has important implications for the Clean Air Act and the 1995 farm bill. Advocating a systems approach, the committee recommends specific farm practices and new approaches to prevention of soil degradation and water pollution for environmental agencies. The volume details methods of evaluating soil management systems and offers a wealth of information on improved management of nitrogen, phosphorus, manure, pesticides, sediments, salt, and trace elements. Landscape analysis of nonpoint source pollution is also detailed. Drawing together research findings, survey results, and case examples, the volume will be of interest to federal, state, and local policymakers; state and local environmental and agricultural officials and other environmental and agricultural specialists; scientists involved in soil and water issues; researchers; and agricultural producers.

Effect of Heavy Metal Pollution on Plants


Book Description

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.




Biogeochemistry of Trace Metals


Book Description

Biogeochemistry of Trace Metals is a compendium of the most recent information available on the effects of trace metals in soil quality and its potential threat on the transfer of these contaminants to consumers. Most of the chapters in the book were presented as papers during the First International Conference on the Biogeochemistry of Trace Elements (formerly Metals in Soils, Plants, Waters, and Animals) held in Orlando, Florida in May, 1990. Topics discussed include background levels of metals in soils and/or plants (covering western Europe; temperate, humid Europe; and the People's Republic of China); metal cycling and transfer in the food chain in agroecosystems; uptake and accumulation of metals by bacteria, fungi, and invertebrates; mechanistic aspects of metals; the microbial aspects of soil selenium losses; and manganese sorption on soil constituents.




Trace Elements in Terrestrial Environments


Book Description

A comprehensive reference handbook on the important aspects of trace elements in the land environment. Each chapter addresses a particular element and gives a general introduction to their role in the environment, where they come from, and their biogeochemical cycles. In addition to a complete updating of each of the element chapters, this new edition has new chapters devoted to aluminum and iron, soil contamination, remediation and trace elements in aquatic ecosystems. In short, an essential resource for environmental scientists and chemists, regulators and policy makers.
