Download Metal Speciation and Contamination of Soil Book in PDF, ePub and Kindle
Metal Speciation and Contamination of Soil provides a thorough overview of the biogeochemical processes governing the behavior, transport, and bioavailability of heavy metals in contaminated soils and suggests alternative approaches for effective remediation. This important new book contains contributions from experts in various disciplines who explore the issues from theoretical, experimental, and pragmatic perspectives. Topics include redox chemistry, kinetics of metal reactions, spectroscopic characterization of metal ion reactions at surface, modeling hydrologic transport phenomena and colloid-associated transport of metals through the soil profile to ground water, and remediation alternatives.

Download Assessing Speciation and Availability of Heavy Metals in Soils and Soil Solutions Book in PDF, ePub and Kindle
The elevated heavy metal contamination in soils has given rise to the accurate assessment of the availability and mobility of heavy metals and the development of remediation strategies. In this study, soi! column-Donnan membrane technique (SC-DMT) and diffusive gradients in thin¬films gels (DGT) were used to measure the concentration and speciation of Cd, Cu, Ni, Pb, and Zn in eighteen soil solutions, covering a wide range of metal sources (natural and anthropogenic) and concentrations. The availability of Cd, Cu, Pb, and Zn in nine contaminated soils was evaluated by combining chemical extractions with multi-elementary stable isotopic dilution (ID) method. The isotopically exchangeable pool and the operationally defined pool determined by chemical extractions were then compared to probe the relationships between metal availabilities and their bearing phases. The mufti-surface model was used to assess the rote of the major soil components (organic matter, clay, iron hydroxides, and manganese hydroxides) in controlling metal availability. The combination of analytical approaches and speciation modeling can provide mutual validation and a more comprehensive picture of the availability of metals. In our work, model calculation generally provided an adequate prediction of metal speciation in soi! solution and solid phase, and it can be a promising tool to decipher the underlying mechanisms of the differences in metal availabilities in soils.

Download Heavy Metals Release in Soils Book in PDF, ePub and Kindle
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.

Download Heavy Metal Contamination of Soils Book in PDF, ePub and Kindle
Following a description of the various sources and factors influencing the contents of heavy metal pollution in post-catastrophic and agricultural soils, subsequent chapters examine soil enzymes and eggs as bio-monitors, lead adsorption, the effects of arsenic on microbial diversity, and the effects of Mediterranean grasslands on abandoned mines. A third section focuses on the adaptation strategies used by plants and bacteria, such as Pinus sylvestris in industrial areas, and the rhizosphere in contaminated tropical soils and soil treated with sewage sludge. Further topics addressed include strategies of bioremediation, e.g. using transgenic plants as tools for soil remediation. This new volume on heavy metals in soil will be of interest to researchers and scholars in microbial and plant biotechnology, agriculture, the environmental sciences and soil ecology.

Download Environmental Risk Assessment of Soil Contamination Book in PDF, ePub and Kindle
Soil is an irreplaceable resource that sustains life on the planet, challenged by food and energy demands of an increasing population. Therefore, soil contamination constitutes a critical issue to be addressed if we are to secure the life quality of present and future generations. Integrated efforts from researchers and policy makers are required to develop sound risk assessment procedures, remediation strategies and sustainable soil management policies. Environmental Risk Assessment of Soil Contamination provides a wide depiction of current research in soil contamination and risk assessment, encompassing reviews and case studies on soil pollution by heavy metals and organic pollutants. The book introduces several innovative approaches for soil remediation and risk assessment, including advances in phytoremediation and implementation of metabolomics in soil sciences.

Download Speciation of Metals in Water, Sediment and Soil Systems Book in PDF, ePub and Kindle
The particular behavior of trace metals in the environment is determined by their specific physico-chemical form rather than by their total concentration. The introduction of atomic absorption spectrometry has lead to a plethora of scientific papers and reports in which metal concentrations in the environment are only reported as total concentrations. Only recently has the need for improved knowledge on the various forms and bioavailability of metals been realised. Considerable research effort is now devoted to measuring the concentrations of trace metals in surface waters. Efforts are made to couple chemical analytical techniques to process-related biological problems. The proceedings of the workshop on The Speciation of Metals in Water, Sediment and Soil Systems held in Sunne, Sweden, comprise these efforts and show aspects for further cooperation between analytical chemists and biologists.

Download Mineral-water Interfacial Reactions Book in PDF, ePub and Kindle
Clearly explains how to more effectively decipher and predict contaminant fate in the environment by combining kinetic methods and molecular-scale spectroscopic and microscopic techniques to analyze mineral/water interfacial reactions in situ. The book begins with a broad overview, then continues with three sections written by internationally known expert. The first deals specifically with spectroscopic/microscopic techniques that can be used in combination with macroscopic approaches to glean mechanistic information on mineral/water reactions and processes. The second section emphasizes computer models that are used to elucidate surface mediated reaction mechanisms. The remainder of the volume is organized around reaction type, including sorption/desorption of inorganic species, sorption/desorption of organic species, precipitation/dissolution processes, heterogeneous electron transfer reactions, photochemically driven reactions, and microbially mediated reactions. Mineral-Water Interfacial Reactions will be a valuable resource for environmental scientists, geochemists, soil chemists, microbiologists, and marine engineers who need to be familiar with the most current and effective methods for testing and controlling the mobility, speciation, and bioavailability of contaminants in the environment.

Download Metals in Soil Book in PDF, ePub and Kindle
The anthropogenic input of metals into the atmosphere is estimated to be one-to-three orders of magnitude higher than natural fluxes. Soil acts as the primary sink for anthropogenic metals among the environmental spheres. Most metals show indefinite persistence in the ecosphere due to resistance against microbial or chemical-assisted degradation. This edited book is an attempt to compile reviews and case studies from different researchers focusing on different aspects of soil contamination by metals and its subsequent remediation. The book's contents will be useful for researchers and strategists interested in the environmental aspects of soil contamination.
