My interest in these areas of research has been stimulated by a large number of colleagues, many of whom are specialists in the various ele- ments and fields of study covered in this book. This state-of-the-science sum- mary was made possible by the concerted efforts of a great many scientists who provided the research foundation that I have summarized and by my interactions with them to enhance my understanding of the key elements that are discussed. I am very grateful to Jayne Charles who did all of the word processing and worked extensively with the reference list. Susan Binder kindly assisted with graphics and many other aspects of document production. Many of the figures presented in the book were prepared by Susan, Kellie Vaché, and Joe Bischoff. Several colleagues kindly provided helpful comments on an earlier draft of the book. These include Jack Cosby, Steve Kahl, and Kathy Tonnessen. Funding to support preparation of this book was provided by the National Oceanic and Atmospheric Administration, through the National Acid Precip- itation Assessment Program; by the National Park Service, Air Resources Division in Denver, through a grant to the University of Virginia; and the U.S. Environmental Protection Agency, through a grant to Rensselaer Polytechnic Institute. Much of my recent research that is summarized herein was sup- ported by the U.S. Department of Energy, the National Park Service, the U.S. Environmental Protection Agency, and the USDA Forest Service. None of the previously mentioned agencies have cleared this book through their peer or administrative review processes, and no official endorsement is implied. I am very grateful to Mike Uhart, Kathy Tonnessen, Jack Cosby, John Kar- ish, and Jon Zehr for assistance with funding arrangements, as well as sup- port and encouragement. 1416fm Page xi Wednesday, February 9, 2000 11:35 AM © 2000 by CRC Press LLC Preface In 1990, the U.S. National Acid Precipitation Assessment Program (NAPAP) completed the initial phase of what was then the largest environmental research program ever conducted. NAPAP research investigated the causes and effects of, and mitigation strategies for, acidic atmospheric deposition throughout the U.S. This massive environmental research and assessment effort took 10 years to complete, involved hundreds of scientists, engineers, and economists, and cost in excess of $500 million. The scientific culmination of this research was embodied in a series of 27 State of Science and Technol- ogy (SOS/T) Reports that were published in 1990. In addition, a policy report was published in 1991 as the NAPAP Integrated Assessment. After 1990, research funding for work on acidic deposition effects decreased suddenly and substantially. However, many significant research programs were still in progress and/or not yet published, especially in the areas of aquatic effects of nitrogen and sulfur deposition. Results from these efforts appeared in the scientific literature during the early 1990s. In addition, a suite of research projects was initiated post-1990, albeit with somewhat lower funding levels than were common during the heyday of the NAPAP research program. These latter projects took advantage of the significant knowledge gains of the 1980s and, therefore, tended to be more focused and productive than earlier research efforts. Many addressed significant knowledge gaps that had been identified in the SOS/T reports, particularly regarding the interactions between acidic deposition and other sources of natural and anthropogenic acidity. As a consequence, a large body of scientific information related to aquatic effects of atmospheric nitrogen and sulfur deposition has been pro- duced since publication of the SOS/T series of reports. New findings have added support to the state of scientific understanding in some areas, modi- fied it in others, and led to the development of new paradigms and perspec- tives in still other areas of research. The primary aim of this book is to summarize and synthesize major advancements since 1990 in the state of scientific understanding of the aquatic effects of atmospheric deposition of nitrogen and sulfur. It is intended to emphasize advancements in those aspects of aquatic effects research that are of direct policy relevance. Thus, topics concerning quantification of the magnitude of effects and recent developments in the area of predictive mod- eling capabilities are deemed to be of great importance, for the purposes of this book. Special attention is given to those aspects of aquatic effects research that had either been poorly studied pre-1990 or for which major research efforts have been completed in recent years. Topics of special interest include virtually all aspects of nitrogen effects research, as well as the importance of 1416fm Page xiii Wednesday, February 9, 2000 11:35 AM © 2000 by CRC Press LLC natural sources of acidity, the influence of land use and landscape change on the chemistry of drainage waters, and the role of short-term episodic events. This book is intended as a teaching resource and reference source. It pro- vides a comprehensive update on the state of scientific understanding regarding an important environmental topic. It also illustrates the progres- sion and refinement of the scientific knowledge base as research in this field has evolved from general basic research to more narrowly focused efforts aimed at answering specific questions. The target audience includes advanced students of environmental science and engineering and applied environmental practitioners. The latter group includes federal and state land managers and environmental stewards, many of whom are tasked with protecting sensitive natural resources from air pollution degradation and overseeing and prioritizing efforts to mitigate past damage. The wealth of recent knowledge gains summarized here will assist environmental pro- fessionals in making informed judgments regarding air pollution sensitivi- ties, effects, and remediation. The effects of atmospheric nitrogen and sulfur inputs to watershed sys- tems, and the interactions between such inputs and other natural and anthro- pogenic features and stressors, provide an ideal framework for the study of upland hydrobiogeochemistry. Such study requires understanding of the key aspects of myriad disciplines and ecosystem compartments. Major compo- nents include mass balance input–output calculations, the study of hydrolog- ical flowpaths as water moves through the watershed system, and a wide range of interactions between drainage water and soils, geological substrates, and both terrestrial and aquatic biota. Understanding how hydrobio- geochemical processes and cycles govern the response of the entire water- shed to atmospheric inputs and the associated interactions with natural features of the landscape, climate, and human disturbance aids our under- standing of global ecosystems and the influence of human activities on eco- system function and integrity.
