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...

The hydrological and geochemical interactions between clay minerals and organic matter in soils directly influence the reaction, behavior, and mobility of heavy metals in soils. Geochemical and Hydrological Reactivity of Heavy Metals in Soils is one of few books that comprehensively illustrates this cause-and-effect relationship. It highlights analytical techniques such as nuclear magnetic resonance spectroscopy and environmental electron microscopy and reveals how molecular-level modeling is used to remove metal contaminants from the environment. It is thus a practical guide for soil and...

This book outlines experimental methods and mathematical modeling appr oaches as well as cutting-edge knowledge on physical nonequilibrium ph enomena in soils. Topics include soil properties, fluid properties, me chanistic models, transfer function, geostatistics, fractal analysis, cellular-automation fluids, coupling of physical and chemical nonequil ibrium models, confirming and quantifying physical nonequilibrium in s oils, analytical solutions, field-scale research, and environmental im pacts.
