The kinetics of reactions in soil and aquatic environments is a topic of extreme importance and interest. To properly understand the fate of applied fertilizers, pesticides, and organic pollutants with time, and to thus improve nutrient availability and the quality of our groundwater, one must study kinetics. This is the first compre Demonstrates different kinetic methodologies Shows how reactions on soil and soil constituents can be measured by utilizing different techniques Describes rates and mechanisms of interactions with pesticides and organic pollutants with soil Covers the kinetics of chemical weathering Discusses how to use mathematical modeling and computer simulation to model kinetic reactions

As the author states in his Preface, this book is written at a time when scientific and lay communities recognize that knowledge of environmental chemistry is fundamental in understanding and predicting the fate of pollutants in soils and waters, and in making sound decisions about remediation of contaminated soils. Environmental Soil Chemistry presents the fundamental concepts of soil science and applies them to environmentally significant reactions in soil. Clearly and concisely written for undergraduate and beginning graduate students of soil science, the book is likewise accessible to all students and professionals of environmental engineering and science. Chapters cover background information useful to students new to the discipline, including the chemistry of inorganic and organic soil components, soilacidity and salinity, and ion exchange and redox phenomena. However, discussion also extends to sorption/desorption, oxidation-reduction of metals and organic chemicals, rates of pollutant reactions as well as technologies for remediating contaminated soils. Supplementary reading lists, sample problems, and extensive tables and figures make this textbook accessible to readers. Key Features * 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 * Effects of acidic deposition and salinity on contaminant reactions * 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

Soil Physical Chemistry, Second Edition takes up where the last edition left off. With comprehensive and contemporary discussions on equilibrium and kinetic aspects of major soil chemical process and reactions this excellent text/reference presents new chapters on precipitation/dissolution, modeling of adsorption reactions at the mineral/water interface, and the chemistry of humic substances. An emphasis is placed on understanding soil chemical reactions from a microscopic point of view and rigorous theoretical developments such as the use of modern in situ surface chemical probes such as x-ray adsorption fine structure (XAFS), Fournier transform infrared (FTIR) spectroscopies, and scanning probe microscopies (SPM) are discussed.

The fate of heavy metal particles in the environment is important because they tend to be reactive, mobile, and highly toxic. Reactivity and Transport of Heavy Metals in Soils examines the sometimes complex interactions that occur between metals and the soil they occupy. It discusses basic kinetic concepts and covers the predictability and consequences of metal-soil interactions. This practical guide presents and explains heavy metal issues crucial to hazardous waste site cleanup, including:

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.
