Polycyclic aromatic hydrocarbons (PAHs) have found applications in a variety of industries including dyes, drugs, semiconductors, fluorescent reagents, chemiluminescent reagents, and as polychromatic and antistatic additives for plastics. This up-to-date, single volume reference source brings together all essential information on the physical and spectral properties, methods of synthesis, and chemical reactivity of PAHs, both alternant and nonalternant. The title also covers the investigations of PAHs as carcinogens and pollutants. As this important class of molecules are virtually ignored in most chemistry programs, this book will be a strong addition to the work of anyone involved in any aspect of polycyclic aromatic hydrocarbons, chemical carcinogenesis, and environmental pollution.

This thesis presents a comprehensive analysis of the global health impacts of polycyclic aromatic hydrocarbons (PAHs) in ambient air, conducted on the basis of a high-resolution emission inventory, global chemical transport modeling, and probabilistic risk assessment. One of the main strengths of the thesis is the concentration downscaling process, which provides a linkage between emissions and exposure concentrations at a comparatively high resolution. Moreover, by focusing on individual susceptibility, the thesis proposes an instrumental revision of current risk assessment methodology and argues that, if individual susceptibility were not taken into consideration, the overall risk would be underestimated by 55% and the proportion of highly vulnerable populations would be underestimated by more than 90%.

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.

Polycyclic Aromatic Compounds (PAC) are a broad class of compounds whose wide distribution in the environment results from incomplete combustion processes of fossil fuels in power generator, industrial plant and domestic heating, from car exhaust gas and from tobacco smoke. Many PACs are biologically active and in particular many of the PACs with three or more fused rings are carcinogenic. Currently there is concern of the occurrence of these pollutants at ppb (ug.kg-1) le vel. However the predicted 2 to 3% annual increase in the rate of their release into 1 the environment could lead to ppm (ug.g-) levels in the next century. The move to wards stricter control of these pollutants brings with it the need for accurate monito ring of their environmental occurrence. Reliable identification and quantification of these compounds in complex environ mental samples depends greatly on the availability of reference values for their phy sicochemical and biochemical properties. This second volume results from a close collaboration within the General Directorate for Science, Research and Development of the Commission of the European Communities between the Joint Research Centre, Ispra Establishment, the Community Bureau of Reference and expert laboratories of the Member States.

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.

Polycyclic hydrocarbons are of interest in many fields of science: theoretical chemistry, physical chemistry, organic chemistry, dyestuff chemistry and biology. With regards to the latter, I am indebted to Dr. Regina Schoental of the Medical Research Council for the review in this present work of carcinogenesis by polycyclic hydrocarbons. This book is designed to present the facts in a simple and clear order and to derive empirical rules from them, but it does not present a com prehensive theory about polycyclic hydrocarbons. An attempt is made instead to extend classical symbolism into modern structural chemistry. Thus extensive use is made of Robinson's aromatic sextet, which is applied in an uncompromising and strict way. This quasi-classical attempt is encouraged further by such completely unexpected dis coveries as those of Dewar benzene and of the electronic asymmetry of formally symmetric hydrocarbons. How difficult it is to break away from any established way of thinking has been admirably expressed by Kekule ("Organische Chemie", 1861, Part 1, page 4, translated from German): "All our ideas are based, to an extent much greater than we ordinarily believe, on those of our predecessors. Our accumulated experience, the notions of which our training has accustomed us to, of whatever kind they have been, influence the course of our thoughts far more than we are willing to admit; only too frequently the following of our regularly used, well trodden way of thinking leads to us overlook the simplest of correlations.

A compilation of some 150 refereed papers that were presented at PAH- 13 (October 1991), the first meeting in the PAH symposium series to be convened outside the US. The papers concern the chemistry, biological effects, and measurement of polycyclic aromatic hydrocarbons and related compounds. Following two papers by Gernot Grimmer, who received the 1991 PAH Award at the meeting for his lifetime contributions in all three of the aforementioned areas, the remaining papers are arranged within 13 sections: standard reference materials and methods; PAH transformation and degradation; molecular modeling and theory; PAH-analysis, methodology; PAH analysis in aquatic systems and geological samples; PAH analysis in emission sources and in ambient air; PAHs in coal and petroleum; metabolic activity, mutagenicity; DNA-adducts, mechanisms, characterization; DNA-binding, metabolic activation; PAH exposure, biomonitoring; Comparative metabolism of B[a]P; and bioactivation, metabolites.

Polycyclische aromatische Kohlenwasserstoffe (PAHs) gehören zu den ersten Chemikalien, die als krebserregend für den Menschen erkannt wurden. Erstmals werden in diesem Buch PAHs mit mehr als sieben Ringen auf modernem Stand systematisch abgehandelt. Spezielle Kapitel beschäftigen sich mit Probenvorbereitung und -handling; auch ein Vergleich verschiedener Analyseverfahren ist enthalten. Besonders nützlich für den Laboralltag ist ein ausführlicher Anhang mit Strukturformeln sowie UV-Absorptions- und Fluoreszenz-Emissionsspektren von fast 50 Verbindungen.
