This volume provides a comprehensive overview of aquatic redox chemistry through chapters contributed by many of the leading investigators in the field.

Few processes are as important for environmental geochemistry as the interplay between the oxidation and reduction of dissolved and solid species. The knowledge of the redox conditions is most important to predict the geochemical behaviour of a great number of components, the mobilities of which are directly or indirectly controlled by redox processes. The understanding of the chemical mechanisms responsible for the establishment of measurable potentials is the major key for the evaluation and sensitive interpretation of data. This book is suitable for advanced undergraduates as well as for all scientists dealing with the measurement and interpretation of redox conditions in the natural environment.

Aquatic Chemistry Concepts, Second Edition, is a fully revised and updated textbook that fills the need for a comprehensive treatment of aquatic chemistry and covers the many complicated equations and principles of aquatic chemistry. It presents the established science of equilibrium water chemistry using the uniquely recognizable, step-by-step Pankow format, which allows a broad and deep understanding of aquatic chemistry. The text is appropriate for a wide audience, including undergraduate and graduate students, industry professionals, consultants, and regulators. Every professional using water chemistry will want this text within close reach, and students and professionals alike will expect to find at least one copy on their library shelves. Key Features Extremely thorough, one-of-a-kind treatment of aquatic chemistry which considers: a) chemical thermodynamics fundamentals; b) acid/base, titration, and buffer calculations; c) CO2 chemistry and alkalinity; d) complexation of metal ions by ligands and chelates; e) mineral solubility processes; f) redox chemistry, including the chemistry of chlorine (as in disinfection), oxygen, CO2 and methane, nitrogen, sulfur, iron, and lead, including the story of lead in the drinking water of Flint, Michigan; and g) electrical effects in aqueous solutions including the Debye-Hückel Law (and related equations for activity corrections), double layers, and colloid stability Discussions of how to carry out complex calculations regarding the chemistry of lakes, rivers, groundwater, and seawater Numerous example problems worked in complete detail Special foreword by Jerry L. Schnoor 'There’s a lot to like about a book on water chemistry that lays it out simply. Einstein said that everything should be as simple as it can be, but not simpler. Wise advice. And that is what James F. Pankow has accomplished in the second edition of his textbook, Aquatic Chemistry Concepts. It covers the “waterfront” of essential inorganic chemistry topics, and it supplies enough examples to lead the student toward problem solving.' -From the Foreword, Jerry L. Schnoor

Aquatic Chemistry Concepts fills the need for a true, easy-to-use aquatic chemistry book that goes into the details behind some of the complicated equations and principles of aquatic chemistry. It places established science into a text that allows you to learn and to solve important practical environmental problems. Environmental consultants in all fields, regulators, and libraries will consider this text an excellent reference for its clear explanation of aquatic chemistry principles.

Aquatic chemistry students need a solid foundation in fundamental concepts as well as numerical techniques for solving the variety of problems they will encounter as practicing engineers. For over a decade, Mark Benjamin’s Water Chemistry has brought to the classroom a balanced coverage of fundamentals and analytical algorithms in a student-friendly, accessible way. The text distinguishes itself with longer and more detailed explanations of the relevant chemistry and mathematics, allowing students to understand not only which techniques work best for a given application, but also why those techniques should be applied and what their limitations are. The end result is a solid, thorough framework for comprehending equilibrium in complex aquatic systems. The second edition includes a thorough introductory explanation of chemical reactivity and a new chapter on reaction kinetics, providing much-needed context, as well as full treatments of the tableau method and TOTH equation. The discussion of the thermodynamic perspective on chemical reactivity has been extensively revised. The entire book now integrates Visual Minteq—the most popular software for analyzing chemical equilibria—into the problem-solving approach. Additional exercises range more widely in difficulty, giving instructors more flexibility and diversity in their assignments.

There is need in environmental research for a book on fresh waters including rivers and lakes. Compared with other books on the topic, this book has a unique outline in that it follows pollution from sources to impact. Included in the text is the treatment of various tracers, ranging from pathogens to stable isotopes of elements and providing a comprehensive discussion which is lacking in many other books on pollution control of natural waters. Geophysical processes are discussed emphasizing mixing of water, interaction between water and the atmosphere, and sedimentation processes. Important geochemistry processes occurring in natural waters are described as are the processes specific to nutrients, organic pollutants, metals, and pathogens in subsequent chapters. Each of these chapters includes an introduction on the selected groups, followed by the physicochemical properties which are the most relevant to their behavior in natural waters, and the theories and models to describe their speciation, transport and transformation. The book also includes the most up to date information including a discussion on emerging pollutants such as brominated and phosphate flame retardants, perflurochemicals, and pharmaceutical and personal care products. Due to its importance an ecotoxicology chapter has been included featuring molecular biological methods, nanoparticles, and comparison of the basis of biotic ligand model with the Weibull dose-response model. Finally, the last chapter briefly summarizes the regulations on ambient water quality.

Aquatic Chemistry An Introduction Emphasizing Chemical Equilibria in Natural Waters Second Edition Edited by Werner Stumm and James J. Morgan This second edition of the renowned classic unites concepts, applications, and techniques with the growing amounts of data in the field. Expanded treatment is offered on steady-state and dynamic models employing mass-balance approaches and kinetic information. New chapters address such topics as: environmental aspects of aquatic chemistry; new material on organic compounds in natural water systems; the use of stable and radioactive isotopes in chemical and physical processes; the latest advances in marine chemistry; solid-solution interface; kinetic considerations of equilibria; metal-ligand interactions; and an expanded compilation of thermodynamic data for important reactions in natural water systems. 1981 (0 471-04831-3) Cloth 780 pp. (0 471-09173-1) Paper Chemical Processes in Lakes Edited by Werner Stumm This is a multidisciplinary analysis of recent research on the physical, chemical, and biological processes in aquatic systems. Coverage includes: distribution of elements and compounds in water and sediments; sedimentation and sediment accumulation of nutrients and pollutants; eurtophication and acidification; atmospheric deposition; redox-related geochemistry and sediment-water exchange of nutrients and metals; sediment dating and paleolimnology; and steady-state and dynamic models. Most chapters focus on the role of biological processes and the coupling of elemental cycles by organisms. 1985 (0 471-88261-5) 435 pp. Principles of Aquatic Chemistry Francois M. M. Morel Here is a quantitative treatment of the chemical principles that govern the composition of natural waters. Features include an in-depth examination of the use of conservation principles in chemical systems, a review of thermodynamic and kinetic principles applicable to aquatic systems, and a novel presentation of a systematic methodology for equilibrium calculations.
