Air and Noise Pollution Control by Lawrence K. Wang,Norman C. Pereira Pdf
The past few years have seen the emergence of a growing, widespread desire in this country, and indeed everywhere, that positive actions be taken to restore the quality of our environment, and to protect it from the degrading effects of all forms of pollution-air, noise, solid waste, and water. Since pollution is a direct or" indirect consequence of waste, if there is no waste, there can be no pollution, and the seemingly idealistic demand for" zero discharge" can be construed as a demand for zero waste. However, as long as there is waste, we can only attempt to abate the consequent pollution by converting it to a less noxious form. In those instances in which a particular type of pollution has been recognized, three major questions usually arise: 1, How serious is the pollution? 2, Is the technology to abate it available? and 3, Do the costs of abatement justify the degree of abatement achieved? The principal intention of this series of books is to help the reader to formulate answers to the last two of the above three questions. The traditional approach of applying tried-and-true solutions to specific pollution problems has been a major factor contributing to the success of environmental engineering, and in large measure has accounted for the establishing of a "methodology of pollution control.

Noise Pollution: Causes, Effects and Management by Julia Page Pdf
The propagation of noise that can have a harmful impact on the activities of human and animal life is known as noise pollution. Major sources of noise pollution include machines, transport and propagation systems. It can also be caused by loud music, construction and electrical generators. High levels of noise pollution can give rise to cardiovascular effects in humans and increase the incidences of coronary artery disease. Noise can also have a detrimental effect on animals. It can upset the delicate balance in predator or prey detection and avoidance, as well as interfere in the use of sound for communication. Different approaches, evaluations and methodologies and advanced studies on noise pollution have been included in this book. It covers in detail some existent theories and innovative concepts revolving around this problem. The book is appropriate for those seeking detailed information in this area.
Environmental Pollution and Control by J. Jeffrey Peirce,P Aarne Vesilind,Ruth Weiner Pdf
Complex environmental problems are often reduced to an inappropriate level of simplicity. While this book does not seek to present a comprehensive scientific and technical coverage of all aspects of the subject matter, it makes the issues, ideas, and language of environmental engineering accessible and understandable to the nontechnical reader. Improvements introduced in the fourth edition include a complete rewrite of the chapters dealing with risk assessment and ethics, the introduction of new theories of radiation damage, inclusion of environmental disasters like Chernobyl and Bhopal, and general updating of all the content, specifically that on radioactive waste. Since this book was first published in 1972, several generations of students have become environmentally aware and conscious of their responsibilities to the planet earth. Many of these environmental pioneers are now teaching in colleges and universities, and have in their classes students with the same sense of dedication and resolve that they themselves brought to the discipline. In those days, it was sometimes difficult to explain what indeed environmental science or engineering was, and why the development of these fields was so important to the future of the earth and to human civilization. Today there is no question that the human species has the capability of destroying its collective home, and that we have indeed taken major steps toward doing exactly that. And yet, while, a lot has changed in a generation, much has not. We still have air pollution; we still contaminate our water supplies; we still dispose of hazardous materials improperly; we still destroy natural habitats as if no other species mattered. And worst of all, we still continue to populate the earth at an alarming rate. There is still a need for this book, and for the college and university courses that use it as a text, and perhaps this need is more acute now than it was several decades ago. Although the battle to preserve the environment is still raging, some of the rules have changed. We now must take into account risk to humans, and be able to manipulate concepts of risk management. With increasing population, and fewer alternatives to waste disposal, this problem is intensified. Environmental laws have changed, and will no doubt continue to evolve. Attitudes toward the environment are often couched in what has become known as the environmental ethic. Finally, the environmental movement has become powerful politically, and environmentalism can be made to serve a political agenda. In revising this book, we have attempted to incorporate the evolving nature of environmental sciences and engineering by adding chapters as necessary and eliminating material that is less germane to today's students. We have nevertheless maintained the essential feature of this book -- to package the more important aspects of environmental engineering science and technology in an organized manner and present this mainly technical material to a nonengineering audience. This book has been used as a text in courses which require no prerequisites, although a high school knowledge of chemistry is important. A knowledge of college level algebra is also useful, but calculus is not required for the understanding of the technical and scientific concepts. We do not intend for this book to be scientifically and technically complete. In fact, many complex environmental problems have been simplified to the threshold of pain for many engineers and scientists. Our objective, however, is not to impress nontechnical students with the rigors and complexities of pollution control technology but rather to make some of the language and ideas of environmental engineering and science more understandable.
Environmental noise is defined as the noise emitted from sources such as road, rail and air traffic, industries, construction and public works, and the neighborhood. Noise has been ranked high among forms of pollutions, which include air pollution, radioactive waste pollution, water pollutions, etc. In recent years, noise has received considerable worldwide attention as a result of the many studies linking noise pollution to various health effects that include auditory as well non-auditory health effects. It should be noted here that the effect of noise is seldom catastrophic, and is often only transitory. However, its adverse effects can be cumulative with prolonged or repeated exposure. Noise with daily activities and it causes sleep disruption, masking of speech, reduction in performance and the inability to enjoy one's property or leisure time. It impairs the quality of life. In addition, several studies have linked extended exposure to high noise levels to cardiovascular diseases, including high blood pressure and irregular heartbeat. It has also been reported that high noise levels have an economic effects, especially tourism and real estate sectors, where it has been reported that the prices of houses tend to be higher in quite areas. There is also some evidence that noise can adversely affect general health and well-being in the same manner as chronic stress. Because of these factors, and the recent public awareness of the adverse effects of noise in the last few decades, many studies and noise monitoring programs have been established in various parts in the world. These studies and programs focus on measurements of perceived sound levels in communities, in the workplace (occupational noise), near airports and in public parks. A second area of research, which is getting more attention in recent years, focuses on assessing the effects of noise on individuals and communities, i.e. noise annoyance. This book discusses several topics that include driver style influence in the vehicle acoustic emissions in urban traffic; reaction to hybrid noise in communication; otoacoustic emissions by product distortion in metallurgical workers exposed to different doses of occupational noise; underwater noise pollution; and noise pollution in Zimbabwe.
