Hydrogeochemistry of Aquatic Ecosystems Discover the geological foundation of global water supply, focusing on resource conservation and restoration Hydrogeochemistry explores the connections between the geology of a region and the chemical characteristics and quality of its water sources, including such factors as erosion, evaporation, and, increasingly, man-made activities. With the emergence of climate change as a major factor reshaping water quality and availability, the need to understand interactions between hydrochemistry and geology has never been greater. Hydrogeochemistry of Aquatic Ecosystems meets this need by offering foundational knowledge about the hydrochemistry of different types of aquatic systems, the nature of their interactions with various pollutants and geological processes, and the possibilities and dangers of human intervention. With a particular focus on aqueous resource conservation and restoration, this is a vital, timely guide to a potentially life-saving subject. Hydrogeochemistry of Aquatic Ecosystems readers will also find: Detailed treatment of water-sediment interactions, arsenic and fluoride enrichment, sand mining, and many other subjects Coverage throughout of solute acquisition processes, the carbon cycle, and nutrient geochemistry Case studies from Asia and Africa demonstrating both natural and anthropogenic hydrogeochemical interactions Hydrogeochemistry of Aquatic Ecosystems is indispensable for professionals and researchers in environmental science and environmental engineering, as well as scholars and advanced graduate students working on aquatic ecosystems or effects of climate change.

This textbook provides a unique and thorough look at the application of chemical biomarkers to aquatic ecosystems. Defining a chemical biomarker as a compound that can be linked to particular sources of organic matter identified in the sediment record, the book indicates that the application of these biomarkers for an understanding of aquatic ecosystems consists of a biogeochemical approach that has been quite successful but underused. This book offers a wide-ranging guide to the broad diversity of these chemical biomarkers, is the first to be structured around the compounds themselves, and examines them in a connected and comprehensive way. This timely book is appropriate for advanced undergraduate and graduate students seeking training in this area; researchers in biochemistry, organic geochemistry, and biogeochemistry; researchers working on aspects of organic cycling in aquatic ecosystems; and paleoceanographers, petroleum geologists, and ecologists. Provides a guide to the broad diversity of chemical biomarkers in aquatic environments The first textbook to be structured around the compounds themselves Describes the structure, biochemical synthesis, analysis, and reactivity of each class of biomarkers Offers a selection of relevant applications to aquatic systems, including lakes, rivers, estuaries, oceans, and paleoenvironments Demonstrates the utility of using organic molecules as tracers of processes occurring in aquatic ecosystems, both modern and ancient

Organic Acids in Aquatic Ecosystems E. M. Perdue E. T. Gjessing Editors This volume consists of background papers and reports on discussions focused on identifying major processes that cause spatial and temporal variability in properties and concentrations of organic acids in aquatic ecosystems. Scientists in aquatic chemistry, environmental chemistry, soil chemistry, organic geochemistry, water treatment technology, forest ecology, and stream ecology collectively address four major questions: What is the composition of organic acids and how are they characterized? How are acid-base properties of "DOC" measured and modeled and how do they affect aquatic ecosystems? How do organic acids interact with solutes, surfaces, and organisms? What are the temporal and spatial variations of organic acids at the ecosystem level? This volume provides an up-to-date assessment of the state of knowledge of organic acids in aquatic ecosystems and identifies promising areas of new research that deserve the attention of all scientists who study chemical and biological processes in natural waters, where the importance of organic acids in such processes is not yet fully recognized.

Chemical Dynamics in Freshwater Ecosystems reviews the processes that control the distribution and impacts of chemical substances discharged into freshwater aquatic environments. The book focuses on the relationships between chemical emissions and the resulting ambient concentration in water, sediments, fish, benthos, plants, and other components of real aquatic ecosystems. Hydrodynamics, sediment dynamics, chemical fate processes, bioaccumulation, and food-chain transfer are major topics discussed in the book. Case studies and models are used to illustrate how quantitative predictions of chemical dynamics and behavior in the aquatic environment can be made. Chemical Dynamics in Freshwater Ecosystems is an excellent reference for aquatic toxicologists, wildlife toxicologists, wildlife biologists, environmental chemists, governmental regulators, environmental modelers, consultants, and students studying the effects of chemicals on aquatic environments.

Acidic deposition and its effect on aquatic ecosystems have become major scientific and public policy issues in the United States since the early 1970s, and many diverse studies have been completed. This book is the first comprehensive, integrated synthesis of available information on current and potential effects of acidic precipitation on lakes and streams in geographic regions with a high number of low-alkalinity surface water from the Adirondacks and the Southern Blue Ridge to the Upper Midwest to the Rocky Mountains, the Sierra Nevada, and the Cascades. Written by leading authors, the book examines the current status of water chemistry and characterizes the processes controlling water chemistry on a regional basis by using and comparing high-quality data sets. Methods for the assessment of long-term changes in water chemistry and their effects in fish and other biota are also presented. The book amply illustrates the substantial diversity among geographical regions with respect to the nature of surface waters and the complexity of their response to acidic deposition. This volume will be of great interest to researchers in limnology, aquatic ecology, environmental chemistry, hydrology, and atmospheric sciences. It will also serve as an important reference for environmental managers and policy makers.

Biogeochemistry of Estuaries offers a comprehensive and interdisciplinary approach to understanding biogeochemical cycling in estuaries. Designed as a text for intermediate to advanced students, this book utilizes numerous illustrations and an extensive literature base to impart the current state-of-the-art knowledge in this field. While many of the existing books in estuarine science are comprised of edited volumes, typically focused on highly specific topics in estuaries,Biogeochemistry of Estuaries provides, for the first time, a unique foundation in the areas of geomorphology, geochemistry, biochemistry, aqueous chemistry, and ecology, while making strong linkages (trhoughout the text) to ecosystem-based processes in estuarine sciences. Estuaries, located at the interface between land and the coastal ocean are dynamic, highly productive systems that, in many cases, have been historically associated with development of many of the great centers of early human civilization. Consequentially, these systems have and continue to be highly impacted by anthropogenic inputs. This timely book takes the foundational basis of elemental cycling in estuarine and applies it to estuarine management issues. Biogeochemistry of Estuaries will be welcomed by estuarine/marine scientists, ecologists, biogeochemists, and environmentalists around the world.

To fulfill its commitment to clean water, the United States depends on limnology, a multidisciplinary science that seeks to understand the behavior of freshwater bodies by integrating aspects of all basic sciences--from chemistry and fluid mechanics to botany, ichthyology, and microbiology. Now, prominent limnologists are concerned about this important field, citing the lack of adequate educational programs and other issues. Freshwater Ecosystems responds with recommendations for strengthening the field and ensuring the readiness of the next generation of practitioners. Highlighted with case studies, this book explores limnology's place in the university structure and the need for curriculum reform, with concrete suggestions for curricula and field research at the undergraduate, graduate, and postdoctoral levels. The volume examines the wide-ranging career opportunities for limnologists and recommends strategies for integrating limnology more fully into water resource decision management. Freshwater Ecosystems tells the story of limnology and its most prominent practitioners and examines the current strengths and weaknesses of the field. The committee discusses how limnology can contribute to appropriate policies for industrial waste, wetlands destruction, the release of greenhouse gases, extensive damming of rivers, the zebra mussel and other "invasions" of species-- the broad spectrum of problems that threaten the nation's freshwater supply. Freshwater Ecosystems provides the foundation for improving a field whose importance will continue to increase as human populations grow and place even greater demands on freshwater resources. This volume will be of value to administrators of university and government science programs, faculty and students in aquatic science, aquatic resource managers, and clean-water advocates--and it is readily accessible to the concerned individual.
