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 researchers who discuss their cutting-edge work in this area. The first chapters focus on practical analytical techniques for the measurement and the biological assessment of natural attenuation of trace elements. The following chapters analyze the processes that occur in the natural attenuation of contaminants and nutrients, covering the structural dynamics of mineral surfaces, partitioning, diffusion, fixation, biological and redox processes, and the reversibility of these processes. The remaining chapters consider the impact and implications of natural attenuation in terms of risk assessment, remediation of inorganic contaminants, and bioavailability of essential nutrients. Offering a concise, well-rounded perspective, Natural Attenuation of Trace Element Availability in Soils demonstrates how attenuation processes can significantly impact strategies for soil remediation and serve as a basis for environmental regulations.

Still the Gold Standard Resource on Trace Elements and Metals in Soils This highly anticipated fourth edition of the bestselling Trace Elements in Soils and Plants reflects the explosion of research during the past decade regarding the presence and actions of trace elements in the soil-plant environment. The book provides information on the biogeochemistry of these elements and explores how they affect food quality. Incorporating data from over 1500 new resources, this edition includes the most up-to-date information on the relationship of trace elements to topics such as: Soil natural/background contents Sorption/desorption processes Anthropogenic impact and soil phytoremediation Phytoavailability and functions in plants Contents of food plants The book discusses the assessment of the natural/background content of trace elements in soil, bioindication of the chemical status of environmental compartments, soil remediation, and hyperaccumulation and phytoextraction of trace metals from the soil. The table of contents reflects the IUPAC’s recommendation for numbering element groups, giving the new edition an updated organizational flow. Trace Elements in Soils and Plants, Fourth Edition illustrates why trace elements’ behavior in soil controls their transfer in the food chain, making this book an invaluable reference for agronomists, soil and plant scientists, nutritionists, and geochemists.

Trace Elements in Abiotic and Biotic Environments helps readers understand the fundamental principles and phenomena that control the transfer of trace elements. This book describes the occurrence and behavior of trace elements in rocks, soil, water, air, and plants, and also discusses the anthropogenic impact to the environment. In addition, it covers the presence of trace elements in feeds, as either contaminants or as nutritional or zootechnical additives, and their transfer across the food chain to humans. Also discussed is international legislation on trace elements for both micronutrients and contaminants in soil and plant food. A special focus is placed on the human health effects of both trace element deficiency and excess. All trace elements are covered—from aluminum to zirconium—as well as rare-earth elements (actinides and lanthanides).

This third edition of the book has been completely re-written, providing a wider scope and enhanced coverage. It covers the general principles of the natural occurrence, pollution sources, chemical analysis, soil chemical behaviour and soil-plant-animal relationships of heavy metals and metalloids, followed by a detailed coverage of 21 individual elements, including: antimony, arsenic, barium, cadmium, chromium, cobalt, copper, gold, lead, manganese, mercury, molybdenum, nickel, selenium, silver, thallium, tin, tungsten, uranium, vanadium and zinc. The book is highly relevant for those involved in environmental science, soil science, geochemistry, agronomy, environmental health, and environmental engineering, including specialists responsible for the management and clean-up of contaminated land.

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.

Historically, research on the methods and amounts of trace element application to agriculture soils for correcting plant deficiencies has received major attention. More recently, due to industrial development and past disposal activities, trace elements are considered to be important environmental contaminants that affect all components in the atmosphere and in aquatic and terrestrial systems. Prepared by a multi-disciplinary group of scientists, Trace Elements in Soil: Bioavailability, Flux, and Transfer explores and discusses emerging issues in biogeochemistry research. The book emphasizes the role of biological and chemical interactions and discusses the newest research and its application to major environmental problems. It provides a concise compilation of current research and a handy, time-saving reference. With contributions from an international panel of authors, the book focuses on trace element issues in developing countries and environmentally sound techniques such as stabilization and bioremediation. Fundamental yet complex, bioavailability can be relatively simple to parameterize under controlled simulated conditions. This is not always the case under field conditions. To expand our understanding of the fate and transport of trace elements in soils, the methods of assessing trace element bioavailability, flux, and transfer among the different soil components needs to be redefined and developed. Trace Elements in Soil: Bioavailability, Flux, and Transfer is unique in its emphasis on bioavailability and how trace element contamination ultimately effects plants, wildlife, and human population.

Groundwater resources naturally contain high levels of arsenic in many parts of the world. Over the last two decades, the As-containing groundwater in South-East Asia has received much attention, but the situation is just as crucial in Latin America, where the number of studies is still relatively low, and the extent and severity of As-exposure in the populations has yet to be fully evaluated. This book aims to promote knowledge of the occurrence and genesis of As-rich groundwater in Latin America. It deals with constraints on the mobility of As in groundwater, As-uptake from soil and water by plants, As-propagation through the food chain, human health impacts, and As-removal technologies. Case studies are presented from Argentina, Bolivia, Chile, Ecuador, El Salvador, Mexico, Nicaragua and Peru, amongst others, and are viewed against the background of experience from other world regions. The book is a state-of-art overview of arsenic research in Latin America. It aims to create interest within the Latin American countries affected by the presence of arseniferous aquifers and to increase awareness among administrators, policy makers and company executives. It will also serve to inform the international scientific community, and improve international cooperation on arsenic in groundwater.
