The Watt Committee on Energy became active in of the effects on buildings, for instance. Proposals the study of Acid Rain during 1982. Perhaps the for action should therefore concentrate on measures only aspect of the subject that has become more that promise a real improvement as a result of certain during the subsequent five years is that the expenditure. expression 'Acid Rain' is used loosely in public The Watt Committee's study of this subject has been in two phases. The first dealt with the nature debate for a complex of industrial and environ mental phenomena. Among these, Acid Rain in the of the problem, and culminated in the publication straightforward meaning of the words-rain and of Watt Committee Report No. 14 in 1984. That perhaps snow having a significantly high level of Report was divided into four sections, each of acidity-is of only limited importance. To represent which was prepared by a sub-group of the working this perspective, therefore, the Watt Committee Ex group: they dealt respectively with the fate of air borne pollution, vegetation and soils, fresh water ecutive decided that the study leading to the present Report should be entitled 'Air Pollution, Acid Rain and remedial strategy. In the second phase, these and the Environment'. sub-groups have brought their sections up-to-date The Watt Committee's interest in Acid Rain and a fifth sub-group was appointed to study arises from the fact that, among its causes, the buildings and non-living materials.

This series is dedicated to serving the growing community of scholars and practitioners concerned with the principles and applications of environmental management. Each volume will be a thorough treatment of a specific topic of importance for proper management practices. A fundamental objective of these books is to help the reader discern and implement human's stewardship of our environment and the world's renewable resources. For we must strive to understand the relationship between humankind and nature, act to bring harmony to it, and nurture an environment that is both stable and productive. These objectives have often eluded us because the pursuit of other individual and societal goals has diverted us from a course of living in balance with the environment. At times, therefore, the environmental manager may have to exert restrictive control, which is usually best applied to humans, not nature. Attempts to alter or harness nature have often failed or backfired, as exemplified by the results of imprudent use of herbicides, fertilizers, water, and other agents. Each book in this series will shed light on the fundamental and applied aspects of environmental management. It is hoped that each will help solve a practical and serious environmental problem.

Fundamentals of Air Pollution is an important and widely used textbook in the environmental science and engineering community. This thoroughly revised fifth edition of Fundamentals of Air Pollution has been updated throughout and remains the most complete text available, offering a stronger systems perspective and more coverage of international issues relating to air pollution. Sections on pollution control have been reorganized and updated to demonstrate the move from regulation and control approaches to green and sustainable engineering approaches. The fifth edition maintains a strong interdisciplinary approach to the study of air pollution, covering such topics as chemistry, physics, meteorology, engineering, toxicology, policy, and regulation. New material includes near-road air pollution, new risk assessment approaches, indoor air quality, the impact of biofuels and fuel additives, mercury emissions, forecasting techniques, and the most recent results from the National Air Toxics Assessment. - Stronger systems approach, emphasizing the impact of air pollution on ecosystems and human health - Risks, measures, models, and control of air pollution are discussed at scale – starting at the individual/niche level and expanding to planetary/global scale - Increased emphasis on international issues, including coverage of European initiatives and discussions of the impact of emerging economies like India and China - Updated references, standards, and methods throughout the book make this the most current air pollution text/reference on the market - All new end-of-chapter problems enhance its usefulness as a course text
