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.

Analytical Chemistry of Polycyclic Aromatic Compounds focuses on the chemical and physical properties of the polycyclic aromatic compounds, critically evaluating various chromatographic and spectroscopic methods. This book discusses how gas chromatography and high-performance liquid chromatography can be both competitive and complementary analytical methods. Ancillary techniques of both are emphasized for the structural elucidation of individual polycyclic aromatic compounds in complex mixtures. The merits of spectroscopic methods in both structural work and quantitation are also described. This text likewise provides background information concerning the chemistry, occurrence, and toxicology of polycyclic aromatic compounds, including the isolation of polycyclic aromatic compounds from a wide variety of materials and matrices. This publication is recommended to scientists involved with the study of polycyclic aromatic compounds, analysts who need to acquire routine data, and individuals charged with formulating environmental policies and drafting regulations.

The trans-Pacific atmospheric transport of particulate matter (PM)-bound polycyclic aromatic hydrocarbons (PAHs) to remote sites in western North America has been well documented and has triggered research questions regarding to atmospheric transformation of PM-bound PAHs and the potential impacts on human health from their inhalation exposure. In this dissertation, field measurements, theoretical studies, laboratory experiments, and mutagenicity studies were used to begin the address the questions as to whether PM-bound PAHs undergo atmospheric transformation into mutagenic nitro-PAHs (NPAHs) during trans-Pacific atmospheric transport. PM extracts were tested in the Salmonella mutagenicity assay, using Salmonella typhimurium strain TA98 (with and without metabolic activation), to determine the mutagenic activities in relation to the chemical composition of the extracts. The sampling of atmospheric PM with diameter
