Book Description
Recreational boating facilities have historically been areas of polycyclic aromatic hydrocarbon (PAH) contamination brought upon by a variety of sources including stormwater runoff, petroleum product combustion, atmospheric deposition, and fueling operations. These compounds can be released to the environment through disturbance of the sediments. Physicochemical reactions of particulate phase organic matter with organic contaminants in contaminated sediments are one of the factors that may influence the release of these contaminants to the surrounding environment. Relationships between these organic matter components and PAHs may be a deciding factor in determining the fate of these dredged sediments, including their possible re-use. In this study, the relationships between PAH concentrations and organic matter components are presented. Desorption kinetics are examined in a laboratory setting using Tenax® TA resin beads that act as an infinite sink for hydrocarbons. Three marinas, along the Western Basin of Lake Erie were chose to represent common marina settings throughout the basin. Samples were analyzed for organic matter, total organic carbon, black carbon, and PAHs. Concentrations of PAH compounds were variable within and between marinas. Ratios of PAH compounds indicated that most chemicals are from a pyrogenic origin. Although it was the smallest portion of the quantified organic matter, black carbon showed the best correlation to PAH concentrations. Desorption trials show compounds desorb in a biphasic component manner, a fast desorbing component and a slow more "refractory" component. Desorption kinetics were mostly related to the quality of organic matter present, with slow desorbing sites having higher black carbon quantities.

Book Description
This book reviews Polycyclic Aromatic Hydrocarbons (PAHs) and Nitropolycyclic Aromatic Hydrocarbons (NPAHs) contamination in the context of environmental pollution in Asia. It is comprised of the following sections: 1. Fundamental Chemistry and General Characteristics; 2. Analytical Methods; 3. Emission Source and Atmospheric Behavior; 4. Atmospheric Polycyclic Aromatic Hydrocarbons and PM2.5; 5. Polycyclic Aromatic Hydrocarbons in Marine Environments; 6. Metabolic Activation/Toxicities; and 7. Environmental Standards and Guidelines. This volume concentrates on the Far East due to the massive consumption of coal and petroleum in China, which has led to considerable levels of air pollution. High concentration of atmospheric PM2.5 in Beijing have been reported since January 2013 and exposure to such high concentrations may cause respiratory, cardiac and lung diseases. Gathering contributions from international experts, this volume provides a valuable reference guide for global researchers and students interested in learning from the East Asian experience.
