Download and read online ebook Oil Spill Dispersants write by Committee on Understanding Oil Spill Dispersants: Efficacy and Effects. This book was released on 2005. Oil Spill Dispersants available in PDF, EPUB and Kindle. Approximately 3 million gallons of oil or refined petroleum products are spilled into U.S. waters every year. Oil dispersants (chemical agents such as surfactants, solvents, and other compounds) are used to reduce the effect of oil spills by changing the chemical and physical properties of the oil. By enhancing the amount of oil that physically mixes into the water, dispersants can reduce the potential that a surface slick will contaminate shoreline habitats. Although called for in the Oil Pollution Act of 1990 as a tool for minimizing the impact of oil spills, the use of chemical dispersants has long been controversial. This book reviews the adequacy of existing information and ongoing research regarding the effectiveness of dispersants as an oil spill response technique, as well as the effect of dispersed oil on marine and coastal ecosystems. Oil Spill Dispersants also includes recommended steps for policy makers faced with making hard choices regarding the use of dispersants as part of spill contingency planning efforts or during actual spills.

The Use of Dispersants in Marine Oil Spill Response available in PDF, EPUB and Kindle. Whether the result of an oil well blowout, vessel collision or grounding, leaking pipeline, or other incident at sea, each marine oil spill will present unique circumstances and challenges. The oil type and properties, location, time of year, duration of spill, water depth, environmental conditions, affected biomes, potential human community impact, and available resources may vary significantly. Also, each spill may be governed by policy guidelines, such as those set forth in the National Response Plan, Regional Response Plans, or Area Contingency Plans. To respond effectively to the specific conditions presented during an oil spill, spill responders have used a variety of response optionsâ€"including mechanical recovery of oil using skimmers and booms, in situ burning of oil, monitored natural attenuation of oil, and dispersion of oil by chemical dispersants. Because each response method has advantages and disadvantages, it is important to understand specific scenarios where a net benefit may be achieved by using a particular tool or combination of tools. This report builds on two previous National Research Council reports on dispersant use to provide a current understanding of the state of science and to inform future marine oil spill response operations. The response to the 2010 Deepwater Horizon spill included an unprecedented use of dispersants via both surface application and subsea injection. The magnitude of the spill stimulated interest and funding for research on oil spill response, and dispersant use in particular. This study assesses the effects and efficacy of dispersants as an oil spill response tool and evaluates trade-offs associated with dispersant use.

Using Oil Spill Dispersants on the Sea available in PDF, EPUB and Kindle. While major oil spills are rare, oil slicks can have disastrous environmental and economic consequences. This book summarizes research on the use of chemical dispersants: their effectiveness and limitations and the results of using them in different spill situations. Based on laboratory and field research as well as on actual case histories, this book contains a clear-cut set of recommendations for action, planning, and research. Of special interest is the chapter on the biological effects of oil itself and of oil treated with chemical dispersants.

Download and read online ebook Oil Spill Dispersants write by Clayton/Payne. This book was released on 2020-08-26. Oil Spill Dispersants available in PDF, EPUB and Kindle. Oil Spill Dispersants: Mechanisms of Action and Laboratory Tests provides a comprehensive summary of current information available regarding the general formulation of commercial dispersants and their function to lower oil-water interfacial tension. The book considers how chemical dispersants work for oil spills, the properties and chemistry of oils (including weathering state), the variables that affect dispersant performance, and the relationships between laboratory methods and field situations. The book also considers the strengths and limitations of specific laboratory tests, including brief discussions of the applicability of results for estimating dispersant performance in field trials or conditions encountered during real spill events. Laboratory tests are separated into four groups: tank tests, shake/flask tests, interfacial surface tension tests, and flume tests. Rapid-screen field tests are considered as a separate group. Recommendations for improvements in future laboratory testing are offered as well. Oil Spill Dispersants will be useful for regulators evaluating dispersant agents, field personnel involved with using dispersants, laboratory scientists studying performance and behavior of oil and dispersants, and managers responsible for designing studies related to the treatment of oil slicks with dispersants.

Download and read online ebook Responding to Oil Spills in the U.S. Arctic Marine Environment write by National Research Council. This book was released on 2014-08-01. Responding to Oil Spills in the U.S. Arctic Marine Environment available in PDF, EPUB and Kindle. U.S. Arctic waters north of the Bering Strait and west of the Canadian border encompass a vast area that is usually ice covered for much of the year, but is increasingly experiencing longer periods and larger areas of open water due to climate change. Sparsely inhabited with a wide variety of ecosystems found nowhere else, this region is vulnerable to damage from human activities. As oil and gas, shipping, and tourism activities increase, the possibilities of an oil spill also increase. How can we best prepare to respond to such an event in this challenging environment? Responding to Oil Spills in the U.S. Arctic Marine Environment reviews the current state of the science regarding oil spill response and environmental assessment in the Arctic region north of the Bering Strait, with emphasis on the potential impacts in U.S. waters. This report describes the unique ecosystems and environment of the Arctic and makes recommendations to provide an effective response effort in these challenging conditions. According to Responding to Oil Spills in the U.S. Arctic Marine Environment, a full range of proven oil spill response technologies is needed in order to minimize the impacts on people and sensitive ecosystems. This report identifies key oil spill research priorities, critical data and monitoring needs, mitigation strategies, and important operational and logistical issues. The Arctic acts as an integrating, regulating, and mediating component of the physical, atmospheric and cryospheric systems that govern life on Earth. Not only does the Arctic serve as regulator of many of the Earth's large-scale systems and processes, but it is also an area where choices made have substantial impact on life and choices everywhere on planet Earth. This report's recommendations will assist environmentalists, industry, state and local policymakers, and anyone interested in the future of this special region to preserve and protect it from damaging oil spills.
