This book was released on 1986 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical note contains assessments of conventional and special-purpose dredges in removing sediment with minimal sediment resuspension. If sediment resuspension is a critical factor in dredging areas of contaminated material, the following guidance will aid in specifying the dredge and operating conditions. Investigations were conducted as part of the Corps of Engineers Improvement of Operations and Maintenance Techniques (IOMT) Research Program to evaluate the resuspension of sediment into the water column due to dredging operations. Laboratory, field, and literature studies have been used to define the sediment resuspension characteristics of most conventional and several special-purpose dredges. The natural hydrophobic tendency of most organic contaminants and the high sediment-sorptive capacity for inorganic contaminants limits release to the soluble forms and makes the simple measure of sediment resuspension during dredging a relative measure of the potential for contaminant release.

This book was released on 2007-10-30 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some of the nation's estuaries, lakes and other water bodies contain contaminated sediments that can adversely affect fish and wildlife and may then find their way into people's diets. Dredging is one of the few options available for attempting to clean up contaminated sediments, but it can uncover and re-suspend buried contaminants, creating additional exposures for wildlife and people. At the request of Congress, EPA asked the National Research Council (NRC) to evaluate dredging as a cleanup technique. The book finds that, based on a review of available evidence, dredging's ability to decrease environmental and health risks is still an open question. Analysis of pre-dredging and post-dredging at about 20 sites found a wide range of outcomes in terms of surface sediment concentrations of contaminants: some sites showed increases, some no change, and some decreases in concentrations. Evaluating the potential long-term benefits of dredging will require that the U.S. Environmental Protection Agency step up monitoring activities before, during and after individual cleanups to determine whether it is working there and what combinations of techniques are most effective.

Available in PDF, EPUB and Kindle. Book excerpt: The size and concentration of sediment plumes measured in field studies of selected dredging equipment are described. This information is useful when sediment resuspension must be minimized because of adverse environmental impacts which may include the release of sediment-associated chemical contaminants. The information presented here is intended to supplement and update information given in a previous technical note on the same topic (Hayes 1986a). Dredging operations may be required to comply with in-stream State water quality standards based on maximum allowable concentrations of inorganic and organic compounds. Although the majority of materials requiring maintenance dredging In the United States Is uncontaminated, the removal of contaminated sediments (estimated to be less than 10 percent of maintenance materials) poses a serious problem. Hence, a project to study the potential for contaminant release during dredging has been initiated through a field studies program. The field studies described herein were conducted by the Waterways Experiment Station under the Improvement of Operations and Maintenance Techniques (IOMT) research program and in cooperation with other US Army Engineer Districts to evaluate the sediment resuspension characteristics of selected dredges (McLellan et al., in preparation).

Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the past, present and future generation and use of electricity. While noting the importance of electricity to the well-being of people, it argues that all means of electricity generation have adverse ecological consequences. The ecological effects of all the main forms of electricity generation, storage and transmission are reviewed in 14 chapters. The chapters briefly cover the engineering and physics of each method of electricity generation followed by a description of the different ways in which the technology interacts with the natural world. Finally, sections consider the importance of these impacts and how they can be mitigated or avoided. A final chapter summarizes the issues and emphasizes that the only way to truly minimize the impacts of electricity generation is to reduce our consumption and transmission. Future efforts should continue to focus on increasing the efficiency of light production, refrigeration, electrical appliances and batteries.
Download or read book Marine Ecology written by Martin R. Speight and published by John Wiley & Sons. This book was released on 2013-04-30 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book began life as a series of lectures given to second and third year undergraduates at Oxford University. These lectures were designed to give students insights as to how marine ecosystems functioned, how they were being affected by natural and human interventions, and how we might be able to conserve them and manage them sustainably for the good of people, both recreationally and economically. This book presents 10 chapters, beginning with principles of oceanography important to ecology, through discussions of the magnitude of marine biodiversity and the factors influencing it, the functioning of marine ecosystems at within trophic levels such as primary production, competition and dispersal, to different trophic level interactions such as herbivory, predation and parasitism. The final three chapters look at the more applied aspects of marine ecology, discussion fisheries, human impacts, and management and conservation. Other textbooks covering similar topics tend to treat the topics from the point of view of separate ecosystems, with chapters on reefs, rocks and deep sea. This book however is topic driven as described above, and each chapter makes full use of examples from all appropriate marine ecosystems. The book is illustrated throughout with many full colour diagrams and high quality photographs. The book is aimed at undergraduate and graduate students at colleges and universities, and it is hoped that the many examples from all over the world will provide global relevance and interest. Both authors have long experience of research and teaching in marine ecology. Martin Speight’s first degree was in marine zoology at UCNW Bangor, and he has taught marine ecology and conservation at Oxford for 25 years. His research students study tropical marine ecology from the Caribbean through East Africa to the Far East. Peter Henderson is a Senior Research Associate at the University of Oxford, and is Director of Pisces Conservation in the UK. He has worked on marine and freshwater fisheries, as well as ecological and economic impacts and exploitation of the sea in North and South America as well as Europe.
