This is a compilation of topics that are at the forefront of many technical advances and practices in air and water control. These include air pollution control, water pollution control, water treatment, wastewater treatment, industrial waste treatment and small scale wastewater treatment.

Discusses the nature and causes of acid rain, its harmful effects, and possible ways to prevent it.

The causes and consequences of acid rain are subjects of widespread concern and controversy. However the effects of acid deposition on the chemistry of lakes and streams, and on the survival of fish and other aquatic life, have been greatly clarified by the results of a recent Anglo-Scandinavian surface waters research program. This book presents a concise, nonspecialist account of the results and their implications by the director of the program. Based on studies conducted throughout the United Kingdom and northern Europe, the book includes chapters on emissions, transport, and deposition of acid pollution; hydrochemical studies in catchments; catchment process studies; catchment manipulation experiments; the role of hydrology and soil chemistry; palaeolimnological studies; the toxic effects of acidification on fish and other aquatic life; and catchment modelling studies. The highly interdisciplinary nature of the research should appeal to a wide range of scientists and to policy-makers interested in acid rain and its consequences. It is also aimed at postgraduates and third-year undergraduate students in the environmental sciences.

Acid rain is one of the major environmental threats since 19th century. This book reviews the 2012 progress report of US EPA (2013) and summarizes the issue in various environmental aspects. Significant reduction in the SO2, NOx emission and deposition of acid have been occurred via the active implementation of Clean Air Interstate Rule (CAIR), Acid Rain Program (ARP) and NOx budget training program (NBP). Cross state air pollution rule and litigation (CSAPR) implemented by US EPA since 2011 reduces the cross boundary movement of effluents between US and Canada. US national composite means of average SO2 annual mean ambient concentration has been declined by 85% in the period between 1980 and 2012.

Fundamentals of Ecosystem Science, Second Edition provides a comprehensive introduction to modern ecosystem science covering land, freshwater and marine ecosystems. Featuring full color images to support learning and written by a group of experts, this updated edition covers major concepts of ecosystem science, biogeochemistry, and energetics. Case studies of important environmental problems offer personal insights into how adopting an ecosystem approach has helped solve important intellectual and practical problems. For those choosing to use the book in a classroom environment, or who want to enrich further their reading experience, teaching and learning assets are available at Elsevier.com. - Covers both aquatic (freshwater and marine) and terrestrial ecosystems with updated information - Includes a new chapter on microbial biogeochemistry - Features vignettes throughout the book with real examples of how an ecosystem approach has led to important change in policy, management, and ecological understanding - Demonstrates the application of an ecosystem approach in synthesis chapters and case studies - Contains new coverage of human-environment interactions

"awareness" of the world's citizens and encourage governments to devote more attention and resources to address this issue. The series editors thank the international panel of contributors for bringing this timely series into completion. We also wish to acknowledge the very insightful input of the following colleagues: Prof. A. L. Page of the University of California, Prof. T . C. Hutchinson of the University of Toronto , and Dr. Steve Lindberg of the Oak Ridge National Laboratory. We also wish to thank the superb effort and cooperation of the volume editors in handling their respective volumes. The constructive criticisms of chapter review ers also deserve much appreciation. Finally, we wish to convey our appreciation to my secretary, Ms. Brenda Rosier, and my technician, Ms. Claire Carlson, for their very able assistance in various aspects of this series. Aiken, South Carolina Domy C. Adriano Coordinating Editor Preface to Acidic Precipitation, Volume 5 (Advances in Environmental Science) Acidification research has been ongoing for several decades. It was not until the 1980s, however, that scientists began to recognize the complex ity of the factors causing the decline in forest growth and deterioration of fish populations in acidified lakes. The general feeling, based on correla tive research, was that long-range transported air pollution was the main cause. Proof, however, was difficult to obtain because of complex interac tions of various stress factors including natural ones.
