Opis

The completion of the initial phase of the U.S. National Acid Precipitation Assessment Program (NAPAP) in 1990 marked the end of the largest environmental research and assessment effort to that time. The resulting series of 27 State of Science and Technology (SOS/T) Reports and the NAPAP Integrated Assessment represent a decade of work by hundreds of scientists, engineers, and economists. Since then, many new, significant, more refined studies on acid deposition have been completed and published, considerably broadening knowledge in this area.
Aquatic Effects of Acidic Deposition summarizes and synthesizes these major advancements, particularly those topics that are directly relevant to policy making. It offers complete coverage of recent findings that have substantiated, deepened, modified, or in some cases, revolutionized scientific understanding in environmental research.
This resource addresses the quantification of effects and recent developments in predictive modeling capabilities. It covers virtually all aspects of nitrogen effects research, the importance of natural sources of acidity, the influence of land use and landscape change on drainage water chemistry, and the role of short-term episodic events.
This comprehensive update thoroughly illustrates the progression and refinement in the field. Aquatic Effects of Acidic Deposition helps you make educated decisions based on the most recent, reliable data for air pollution sensitivities, effects, remediation, and future research.
