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
Biodegradation of phenanthrene was studied in soil slurry reactors in the presence and absence of a surfactant solution. Results showed that the presence of surfactants slowed the initial biodegradation rate of phenanthrene, but increased the total mass of phenanthrene degraded over a four day period by 30%. A mathematical model was developed to simulate the dynamics of the biodegradation of low solubility hydrocarbons in the presence of soils and surfactants. Processes such as the desorption kinetics of the hydrocarbon from soil, the sorption of the surfactant onto soil and its effect on the sorption of the hydrocarbon, and the bioavailability of the hydrocarbon in different phases of the system are included in the model formulation. The experimental results were measured independently. The model was used to investigate the effect on the overall biodegradation of phenanthrene due to different operating conditions. simulation results showed that there is a system-specific optimum surfactant concentration, above which bioremediation is hindered.
