Book Description
Since the early 1970s, experts have recognized that petroleum pollutants were being discharged in marine waters worldwide, from oil spills, vessel operations, and land-based sources. Public attention to oil spills has forced improvements. Still, a considerable amount of oil is discharged yearly into sensitive coastal environments. Oil in the Sea provides the best available estimate of oil pollutant discharge into marine waters, including an evaluation of the methods for assessing petroleum load and a discussion about the concerns these loads represent. Featuring close-up looks at the Exxon Valdez spill and other notable events, the book identifies important research questions and makes recommendations for better analysis ofâ€"and more effective measures againstâ€"pollutant discharge. The book discusses: Inputâ€"where the discharges come from, including the role of two-stroke engines used on recreational craft. Behavior or fateâ€"how oil is affected by processes such as evaporation as it moves through the marine environment. Effectsâ€"what we know about the effects of petroleum hydrocarbons on marine organisms and ecosystems. Providing a needed update on a problem of international importance, this book will be of interest to energy policy makers, industry officials and managers, engineers and researchers, and advocates for the marine environment.

Book Description
A laboratory scale experiment was conducted at the Coast Guard R & D Center during the winter 1979/1980 and winter 1980/1981 seasons to simulate the weathering of oil under Arctic conditions. The experiment consisted of weathering four types of oil (No. s heating oil, Prudhoe Bay crude oil, No. 4 fuel oil, and No. 6 fuel oil) in open boxes under environmental conditions of periods of up to a month. Samples were collected at various intervals for physical and chemical properties analysis. The experiment focused on evaporation as the primary weathering process in the Arctic. Environmental conditions (temperature and wind speed) were monitored continuously to allow calculation of evaporative exposure. Data analysis consisted of plotting the various physical and chemical parameters (density, viscosity, solubility, etc.), against evaporative exposure, to study the quantiative dependence of the physical and chemical properties on evaporation. The results indicate a well-defined functional dependence of several important physical properties on evaporation. This has led to separate study by the University of Toronto to develop a simplified evaporation model. The results also identified two specific areas where further research is required; namely, the emulsification of oil and the combustion of oil under Arctic conditions.

Book Description
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.

Book Description
This book covers research completed between 1981 and May 1985 and includes: reviews of recent studies, sitings and investigations at spills-of-opportunity as well as results of recent arctic and sub-Arctic oil weathering experiments and observations on the behavior of crude oil in the presence of ice. Topics covered include the following: laboratory studies of formation and stability of water-in-oil emulsions; selected case histories of the more detailed chemistry studies of mousse behavior and long term fate in near-coastal and open ocean oil spills/blowouts; tar ball formation and distribution; and algorithms and computer programs to simulate the formation of water-in-oil emulsion.

Book Description
Extensively revised and updated, Handbook of Water Analysis, Third Edition provides current analytical techniques for detecting various compounds in water samples. Maintaining the detailed and accessible style of the previous editions, this third edition demonstrates water sampling and preservation methods by enumerating different ways to measure chemical and radiological characteristics. It gives step-by-step descriptions of separation, residue determination, and clean-up techniques. See What’s New in the Second Edition: Includes five new chapters covering ammonia, nitrates, nitrites, and petroleum hydrocarbons, as well as organoleptical and algal analysis methodology Compares older methods still frequently used with recently developed protocols, and examines future trends Features a new section regarding organoleptical analysis of water acknowledging that ultimately the consumers of drinking water have the final vote over its quality with respect to odor, flavor, and color The book covers the physical, chemical, and other relevant properties of various substances found in water. It then describes the sampling, cleanup, extraction, and derivatization procedures, and concludes with detection methods. Illustrated with procedure flow charts and schematics, the text includes numerous tables categorizing methods according to type of component, origin of the water sample, parameters and procedures used, and application range. With contributions from international experts, the book guides you through the entire scientific investigation starting with a sampling strategy designed to capture the real-world situation as closely as possible, and ending with an adequate chemometrical and statistical treatment of the acquired data. By organizing data into more than 300 tables, graphs, and charts, and supplementing the text with equations and illustrations, the editors distill a wealth of knowledge into a single accessible reference.

Book Description
Oil Spill Science and Technology, Second Edition, delivers a multi-contributed view on the entire chain of oil-spill related topics from oil properties and behaviors, to remote sensing through the management side of contingency planning and communicating oil spill risk perceptions. Completely new case studies are included with special attention to the Deepwater Horizon event, covering the impacts of wetlands and sand beaches, a mass balance approach, and the process for removing petroleum chemicals still trapped near Alabama beaches. Other new information on lingering oil left behind from the Exxon Valdez spill, the emergency system used in the Prestige incident, and coverage on the Heibei Spirit spill in Korea are also included. This updated edition combines technology with case studies to identify the current state of knowledge surrounding oil spills that will encourage additional areas of research that are left to uncover in this critical sector of the oil and gas industry. - Updated with new chapters on risk analysis and communication, contingency planning, restoration, and case studies - Supported with technological advances evolved from the Deepwater Horizon/BP oil tragedy and events in the Arctic/Antarctic - Multi-contributed from various industry experts to provide an extensive background in technical equipment and worldwide procedures used today
