Available in PDF, EPUB and Kindle. Book excerpt: Understanding the mechanisms associated with metal complexes and the sequestering metal contaminants in the environment is essential for effective remediation. Heavy Metal Release in Soils describes and quantifies desorption/release kinetics and dissolution reactions in the release of heavy metals from soil. The book focuses on: New techniques - microscopic surface techniques, NMR and electrophoresis, XAFS, SFM, and time-resolved ATR-FTIR Theoretical analysis and kinetic approaches - adsorption/desorption hysteresis, competitive sorption and transport, multi-component models, speciation kinetics, isotherms and soil and metal parameters, and the role of soil properties on transport Applications - arsenic speciation and mobility in contaminated soils, modeling activity of CD, Zn, and Cu in contaminated soils, and in situ chemical immobilization A timely addition to the literature, this book highlights the desorption/release mechanisms for the purpose of resolving remediation dilemmas in contaminated environments. It gives you the added advantage of case studies at both the microscopic and macroscopic scales, and provides both experimental and numerical investigations. With contributions from an international panel of authors, Heavy Metals Release in Soils fills a gap in the current literature concerned with subsurface contaminant fate and transport processes.

Available in PDF, EPUB and Kindle. Book excerpt: The chapters of this book were originally presented at the Fourth International Conference on the Biogeochemistry of Trace Elements, in June 1997 at Berkeley, California. The results of that symposium are now available to assist both specialists and those concerned with broader environmental issues. The first four chapters of Fate and Transport of Heavy Metals in the Vadose Zone are devoted to sorption-desorption processes. Subjects include the kinetics of trace metal sorption-desorption, adsorption of nickel and their isotherms, cadmium reactions, and retention mechanisms of both linear and nonlinear types. The next three sections describe complexation and speciation processes. The authors consider the effect of humic and fulvic acids, the binding of copper with organic matter, and the rate of dissolved selenium. Chapters eight through eleven scrutinize the bioavailability and retention of heavy metals and their mobility in the vadose zone. Twelve details plant-available concentration levels for heavy metals in the vadose zone. The last section relates case studies that are relevant to environmental affairs. Features

Available in PDF, EPUB and Kindle. Book excerpt: Understanding the kinetics of trace metals sorption and desorption on soils is important for better prediction of metal behavior in the environment. In this dissertation, the effect of solution chemistry and soil composition on trace metal sorption and desorption kinetics was investigated. Based on the experimental results, predictive kinetics models were formulated and successfully used to describe the kinetics of trace metals sorption and desorption on a variety of soils. The kinetics experiments were conducted with a stirred-flow method. A number of soil samples, which cover a wide range of soil properties from USA and European countries, were selected to test the effect of soil composition. The effects of solution chemistry, pH, metal loadings, and dissolved organic matter (DOM) concentration, were also systematically examined. Most of kinetics experiments were run with two trace metals, copper and zinc, which demonstrated very different kinetics behaviors. The solution pH has significant effect on the Cu and Zn sorption and desorption kinetics which can be accounted by the proton competition. DOM greatly enhanced Cu release but had little effect on Zn, attributed to formation of strong Cu-DOM complex decreasing the Cu ion re-adsorption on soils. Among all soil components, soil organic matter (SOM) is the dominant phase controlling Cu and Zn sorption and desorption kinetics. The effect of residence time was also tested. The kinetics models were formulated and successfully used to describe the Cu and Zn sorption and desorption kinetics under different solution chemistry and soil compositions. The models are based on the mass balance of the flow system and incorporate the chemical reactions between metals and soils. For Zn, a two-site kinetics model, including one fast and one slow site, was necessary. The soil organic carbon (SOC) is the major model parameter accounting for the effect of soil properties on Zn sorption and desorption kinetics. The organic carbon normalized sorption rate coefficients can be applied to different soils based on their SOC concentrations. One set of rate coefficients can be applied to different influent Zn concentrations, which corresponds to the linear portion of the Zn sorption isotherm. The sorption rate coefficients were dependent on solution pH which was accounted for by Zn and proton competition. The same model parameters can be applied to different flow rates.

Book excerpt: Most reported incidents of soil contamination include an array of heavy metals species rather than a single ion. The various interactions in these multicomponent or multiple-ion systems significantly impact the fate and transport of heavy metals, and competition for sorption sites on soil matrix surfaces is a common phenomenon.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the behavior and impact of trace metals in the environment by studying typical cases from China such as the Hetao Area of the Yellow River, Shanghai, and Nanjing. Based on samples and experiments on the behavior of pollutants, it systematically discusses the regulation of trace metals’ distribution, accumulation, and migration, associated with the cause of formation demonstration. The author subsequently uses the acquired data to review the evolving trend of trace metal behaviors in natural systems (river or lake water, sediments, and soils), develops suggestions for the prevention of their negative effects, and devise treatments. Moreover, he proposes solutions to difficult research issues such as trace metal speciation extraction, and an analysis, along with operational procedures. Given its scope, the book will provide a valuable guide for researchers and engineers in relevant disciplines of the environmental sciences and engineering, and for environmental policymakers to consult in practices.

Available in PDF, EPUB and Kindle. Book excerpt: This publication constitutes the Proceedings of a Workshop held in Bordeaux (France) on 8th - 10th October, 1980, under the auspices of the Commissior: of the European Communities, as part of the CEC research programme on 'Effluents from Livestock' and the Concerted Action COST 68 bis 'Treatment and Use of Sewage Sludge'. Major changes have taken place in livestock production techniques in recent years. One of the most important developments has been in the field of animal nutrition. Animals are fed to gain maximum liveweight in close relationship with market requirements for carcass and meat quality. With regard to pig production, dietary formulation is based on scientific principles and feed includes a large variety of ingredients to supply optimum feed rations for 'standardised' animals. In order to increase growth rate and to improve feed conversion, copper is added to the ratio~s of fattening pigs in a number of countries, in accordance with the provisions of Council Directives concerning additives in feedingstuffs, as last amended by the 23rd Commission Directive of 4th July 1980.

This book was released on 2012-12-06 with total page 758 pages. Available in PDF, EPUB and Kindle. Book excerpt: Report, the editors replaced the term "speciation" wherever it occurred by "identification and quantification," or "description of abundance," or "reactivity," or "transformation" of a chemical species, according to whichever one of the four meanings the author had evidently meant to convey. In line with the Dahlem Workshop Model, this Report comprises the background papers written in advance of the meeting on the current status of problems in environmental research and on advanced analytical tech niques for the identification and quantification of chemical species, as well as the group reports summarizing the results of the discussions held during the meeting. Each group report was prepared during the meeting by one "rapporteur" with the help of members of that group and finalized by the rapporteur (listed as the first author of the group report) after the meeting, taking into account both verbal comments made during the presentation of the reports in the plenary session at the end of the workshop and written comments received afterwards.

This book was released on 2012-12-06 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The understanding of pollutant transformations, sorption and transport in soils and uptake by plants is the key to controlling contaminant movement towards groundwater and accumulation in food-chains. Some of these major processes were discussed in the first International Workshop on Pollutants in Porous Media, con vened in Israel in 1983 (pollutants in Porous Media, Eds. Yaron, Dagan and Goldshmid, Springer-Verlag, 1984). Since that meeting, research on contaminant impact on the environment expanded considerably. New mechanisms explaining inorganic pollutant par titioning between solid and solution phases in soils were proposed and tested; specific elements and specific reactions were investigat ed, and more case studies to evaluate management practice effects on drinking water quality and accumulation of contaminants in crops were carried out. The recognition that the new knowledge needs to be discussed and evaluated, and the scientific and engineering communities be updated, led the IUPAC (Interna tional Union of Pure and Applied Chemistry) and IAHS (Interna tional Association of Hydrological Sciences) Water Quality Com missions to organize a second International Workshop on pollu tant behaviour in the vadose zone, hosted by the Institute of Soils and Water of the Agricultural Research Organization, Israel. In this workshop, taking place in June 1987, attention was focused on chemical, physico-chemical and microbial-mediated reactions of different contaminants in the vadose zone. This book contains selected works presented in the 1987 workshop by invited special ists from various disciplines and countries.
