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 resouces: trace elements in rocks and minerals; trace elments in soils: total contents; soluble contens and availability; Review on individual trace elements: boron (B); chlorine (Cl); Cobalt (Co); Copper(Cu); Iodine(I); Iron(Fe); Manganese(Mn); Molybdenum(Mo); Selenium(Se); Zinc(Zn).
Natural attenuation has become widely recognized as an effective and low-cost alternative to more expensive engineered remediation. However, there are uncertainties about natural attenuation√s long-term effects and risks to the environment. There is a particular need to develop a high level of understanding of the natural attenuation processes in order to enable its proper implementation. Natural Attenuation of Contaminants in Soils covers this natural process and its proper implementation. It examines the theoretical processes, case studies, protocols, numerical models, and legal aspects in the natural attenuation of organic and inorganic contaminants. The book provides information for evaluation of natural attenuation as a design tool for construction of land-based waste disposal, and as a management control mechanism for leachate plumes. It also provides information for an in situ procedure for structuring remediation options.
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 has become an effective and low-cost alternative to more expensive engineered remediation. This new edition updates the principles and fundamentals of natural attenuation of contaminants with a broader view of the field. It includes new methods for evaluating natural attenuation mechanisms and microbial activity at the lab and field scales. Case studies, actual treatments and protocols, theoretical processes, case studies, numerical models, and legal aspects in the natural attenuation of organic and inorganic contaminants are examined. Challenges and future directions for the implementation of natural attenuation and enhanced remediation techniques are also considered.
A comprehensive and practical overview of the state of the science, Soil Quality Standards for Trace Elements: Derivation, Implementation, and Interpretation addresses the derivation of soil quality standards for trace elements and the implementation of these standards within regulatory and risk assessment frameworks. Forty experts from 11 countrie
"At current atmospheric deposition rates and the neutral to alkaline pH of these soils, attenuation occurred in most soils for Mo. For As, Cd, Co, Cu and Ni it occurred only in soils with abundant total element concentrations or an acidic pH. Minor retention occurred with Pb and Zn. Only Cd and Cu were of concern in leaching waters. The developed model can serve as a decision making tool in the selection of natural attenuation as a remediation strategy." --
The quality of food is such a live issue at the moment that this title is an essential tool for researchers in a variety of disciplines. It provides a review of the key features of trace elements in soils, plants and the food web on which human beings survive. The authors' intention is to summarize up-to-date interdisciplinary data for the concise presentation of our understanding of trace-element transfer in the chain from soil to man.
