Chemical And Biological Regulation Of Aquatic Systems

Chemical and Biological Regulation of Aquatic Systems covers the fundamentals of chemical and microbial process that control the quality of surface water. Topics discussed include the nature and environmental role of surface, complexation and redox reactions; fluxes in the water column and at sediment-water interface; bioavailability; intra- and extra-cellular processes; interactions of microbes with their environment; and microbial ecology. Basic principles are clearly explained and important examples are described in each case. For each environmental process, the respective roles of chemistry and biology are explained. The book features 600 references, 140 figures, and 55 tables. It's an excellent text for students in environmental sciences, researchers involved in quality control, and government and industry professionals who need to learn the fundamentals of an integrated approach to aquatic systems.

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. 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

The Biology of Particles in Aquatic Systems, Second Edition presents the latest information on particulate and dissolved matter found in aquatic habitats ranging from small streams to oceans. Only by studying this matter can we gain an understanding of the functioning of aquatic ecosystems and thus be able to predict changes that may occur as these systems become stressed. Updated and extensively revised, this new edition covers such topics as classification of particulate and dissolved matter, origin and formation of particles aquatic systems, factors affecting particle aggregation, methods for capturing particles by benthic and planktonic animals, and the use of particulate and dissolved organic matter as food.

It emphasizes that both equilibrium and kinetic processes are important in aquatic systems.

The authoritative introduction to natural water chemistry THIRD EDITION Now in its updated and expanded Third Edition, Aquatic Chemistry remains the classic resource on the essential concepts of natural water chemistry. Designed for both self-study and classroom use, this book builds a solid foundation in the general principles of natural water chemistry and then proceeds to a thorough treatment of more advanced topics. Key principles are illustrated with a wide range of quantitative models, examples, and problem-solving methods. Major subjects covered include: * Chemical Thermodynamics * Solid-Solution Interface and Kinetics * Trace Metals * Acids and Bases * Kinetics of Redox Processes * Dissolved Carbon Dioxide * Photochemical Processes * Atmosphere-Water Interactions * Kinetics at the Solid-Water * Metal Ions in Aqueous Solution Interface * Precipitation and Dissolution * Particle-Particle Interaction * Oxidation and Reduction * Regulation of the Chemical * Equilibria and Microbial Mediation Composition of Natural Waters

Continuing concern about water supply and quality, ecosystem sustainability and restoration demands that the modern approach to the management of lakes and reservoirs should be based on a sound understanding of the application of the scientific and ecological principles that underlie freshwater processes. The Lakes Handbook provides an up-to-date overview of the application of ecologically sound approaches, methods and tools using experience gained around the world for an understanding of lakes and their management. Volume one of the Handbook addresses the physical and biological aspects of lakes pertinent to lake management, emphasising those aspects particularly relevant to large, still bodies of water. Volume two then considers lake management, with particular emphasis on sustainability, restoration and rehabilitation. This handbook will be invaluable to ecologists, environmental scientists, physical geographers and hydrologists involved in limnological research, as well as advanced undergraduate and graduate students looking for authoritative reviews of the key areas of limnological study. Brings together basic science and management issues. International coverage and international authors. Reviews management issues at a level suitable for the non-expert.

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.
