Fate of Complex Aromatic Petroleum Hydrocarbons in Marine Sediments: Biological Transformation, Degradation, and Sequestration. Supplement
Abstract
The overall objective was to develop methods to determine the factors that control how low-level mixtures of PANs degrade aerobically in marine sediment systems, in order to determine what rate and extent of biodegradation can be expected in marine sediments under natural and engineered conditions. Specifically, this expansion was added to provide the capability to examine the effects of sediment grain size on laboratory and field observations of PAN behavior. Studies were carried out to characterize the performance of a prototype, bench-top Laser in Situ Scattering Transmissometer (LISST) under a variety of conditions to determine its utility and limitations in the laboratory and field. The impact of grain size effects on experimental and field interpretation was examined. Since grain size is one of the controlling parameters for contaminant distribution, an understanding of the behavior and fate of particles in the field and laboratory as a function of grain size reveals much about the behavior and fate of contaminants in the same environments. These studies have allowed us to optimize these tools to address those goals, and to put the strengths and limitations of the methods in perspective.
