This comprehensive contributed volume presents an account of current research and applications of chemical processes occurring at the interfaces of water with naturally occuring solids. Interactions of solutes with the solid surfaces are looked at from a mechanistic and dynamic point of view rather than a descriptive one. Processes discussed and concepts presented are applicable to all natural waters (oceans and fresh waters as well as soil and sediment water systems) and to the surfaces of natural solids such as minerals, soils, sediments, biota, and humus. Chapters progress from theoretical models and laboratory studies to applications in natural water, soil, and geochemical systems, empha...
Incorporating fundamental principles as well as up-to-date applications in soil formation, this work emphasizes the equal importance of organic and inorganic soil constituents by delineating the role of complex carbohydrates, amino acids, proteins, lipids, nucleic acids, lignins, enzymes, and humic acids in soil reactions. This edition features coverage of the relation of pe-pH with the biochemical cycle, soil air quality and soil humidity, thermodynamics in cation exchange and its connection with the quantity/intensity ratio, and more.
Environmental Soil Chemistry illustrates fundamental principles of soil chemistry with respect to environmental reactions between soils and other natural materials and heavy metals, pesticides, industrial contaminants, acid rain, and salts. Timely and comprehensive discussions of applications to real-world environmental concerns are a central focus of this established text. Provides students with both sound contemporary training in the basics of soil chemistry and applications to real-world environmental concerns Timely and comprehensive discussion of important concepts including: sorption/desorption, oxidation-reduction of metals and organics, and effects of acidic deposition and salinity on contaminant reacions Boxed sections focus on sample problems and explanations of key terms and parameters Extensive tables on elemental composition of soils, rocks and sediments, pesticide classes, inorganic minerals, and methods of decontaminating soils Clearly written for all students and professionals in environmental science and environmental engineering as well as soil science
Experts in soil and environmental sciences as well as in the theory of wave propagation and numerical modeling methods provide a comprehensive account of different aspects of pollutant migration in soils, aquifers, and other geological formations. Emphasis is laid on the analysis of contributing phenomena and their interactions, modeling, and the practical use of such knowledge and models for guidance in disposal operations, preventive measures to minimize ecological damage, prediction of consequences of seepage, and design of remedial actions. Topics covered include the chemical behavior of soils, sorption and retardation, biochemistry of pollutants, ion exchange and kinetics of reactions in soils, measurement of adsorption and desorption, multiphase hydrodynamics, multicomponent wave theory and the coherence concept, nonlinear wave propagation in geological formations, multiphase convective transport, diffusion and fast reaction, modeling pollutant transport, numerical methods, dispersion of contaminants from landfills, risk analysis, water reuse, and radioactive soil contamination at Chernobyl.
Offers an overview of the recent theoretical and practical results achieved in gas-solid (G/S), liquid-solid (L/S), and gas-liquid (G/L) adsorption research.
Metal contamination of groundwater results from many human activities, including agriculture, mining, and the disposal of municipal waste and fly ash. Metals in Groundwater describes the transport of metals to groundwater from these and other sources. It also covers risk assessment of metals in groundwater, coupling of chemicals and hydrological models, and sorption of metals onto soils and clays. The speciation of metals is examined in detail. The book will interest researchers in environmental quality, mining, and agriculture; consultants; industry professionals; and personnel within regulatory agencies.
Under new editorial direction, Advances in Agronomy both continues its long tradition and expands to include innovative methods and technologies. Leading international scientists cover topics in plant and soil sciences, biotechnology, terrestrial ecosystems, and environmental concerns. The second volume under new editorial direction, Advances in Agronomy, Volume 47 focuses on environmental quality and biotechnology. Four articles on soil science cover acid deposition, chemical transport, and surface complexation. Two articles on crop science survey variety fingerprinting and corn evolution. This and related volumes will be of interest to agronomists and biotechnologists in academe, industry, and government. Acidic deposition in forested soils Modeling organic and inorganic chemical transport in soils Surface complexation models in soil chemical systems Fingerprinting crop varieties Evolution of corn
