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 groundwater scientists, ecologists, and government regulators.
