To determine possible harmful effects of aircraft noise on swine, pigs were exposed at Beltsville, Md., to reproduced aircraft and other loud sounds at various stages of the life cycle. Usual intensities ranged from 100 to 120 decibels, but intensities as high as 135 decibels were also employed during the study. No evidence was found that the rate of growth, food intake, or efficiency of feed utilization, or of reproduction was influenced by loud sounds or that ear, adrenal, or thyroid injury detectable by gross examination or microscopic methods took place. As a sensitive criterion of the degree to which sound acts as a stressor, measurements of heart rate before, during, and after exposure were made of a large number of animals. These studies showed that the heart rate is significantly increased during exposure but that it decelerates rapidly after the sound is discontinued.

Environmental Impact Statements, Second Edition has been extensively revised and updated to cover all the requirements for a wide variety of EISs on the federal, state and local levels, including a new chapter devoted to Environmental Justice. An Environmental Impact Statement (EIS) must be completed for any major action that requires a federal permit and may have an adverse effect on the environment. Each federal agency has its own requirements regarding what must appear in the statement. Furthermore, many state and local agencies have their own versions of EISs that must be done for any proposed construction. This book provides a thorough explanation of EISs so that the personnel responsible for preparing these documents will be able to understand the fundamentals of a wide range of environmental factors - ecological and socioeconomic - that comprise an Environmental Impact Statement. This may be the only place that an understandable explanation of the EIS process is located together with a detailed description of how to do an EIS. This is the only book to spell out the EIS process in a straightforward, easy -to-understand style. Written at a level that allows the reader to grasp the fundamentals of EISs, it avoids technical jargon and addresses the topic in layperson's terms. Environmental Impact Statements is an indispensable book for architectural and engineering firms, industrial firms and regulatory agencies on all levels.
