Book Description
Handbook of Chromatography provides a detailed description of significant aspects of polycyclic aromatic hydrocarbons (PAHs). The sources, occurrence, nomenclature, and carcinogenicity of PAHs are covered, and a comprehensive record of data of sample preparation, detection, separation, determination, and characterization of PAHs by liquid chromatography is presented. The book also summarizes extraction and enrichment procedures (e.g., Soxhlet extraction, ultrasonic extraction, liquid-liquid partitioning); presents data from paper chromatography, thin-layer chromatography, high-performance thin-layer chromatography, and electrophoresis of PAHs; and discusses the methodology and applications of extrography in analyzing complex aromatic materials. Handbook of Chromatography also provides a PAHs book directory and a list of suppliers of PAHs and HPLC columns. The volume will be an essential reference for analytical chemists, environmental toxicologists, organic chemists, biomedical specialists, and biotechnicians.

Book Description
This book deals with the sources, distribution, analytical methods, and monitoring of Polycyclic aromatic hydrocarbons (PAH) in the occupational environment. It is hoped that this book will make a contribution to understanding the formation and determination of PAH in work atmosphere and that it will make a particular contribution to occupational health projects. Much of the information given in this book has been generating in studies carried out in cooperation with the Norwegian aluminium industry.

Book Description
High molecular weight -- polycyclic aromatic hydrocarbons (HMW-PAH) are often found where air, water, and soil are subject to higher levels of industrial pollutants. These molecules are environmentally concerning due to their carcinogenic, mutagenic, and tumorigenic propensities. Furthermore, the isomers in this family are challenging to separate due to similar retention parameters, spectroscopic fingerprints, and mass spectral patterns.

Book Description
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.

Book Description
A method was developed for identifying and determining benzo(a)pyrene in a filtered retort water sample from an in situ oil shale process by employing liquid-liquid extraction, dry-column chromatography, thin-layer chromatography and fluorescence spectrometry. The accuracy and precision of the method were good, and the limit of detection was approximately 0.08 ppB. Irreproducible results were obtained with unfiltered retort water samples. Programmed multiple development was used to a limited extent in the separation of polycyclic aromatic hydrocarbons from a shale oil sample. However, results indicated that this separation technique should be investigated further in the separation of polycyclic aromatic hydrocarbons. Benzo(a)pyrene was determined in several shale oil samples by methods developed previously. Polycyclic aromatic hydrocarbons were characterized in several shale oil samples using open-column, dry-column and thin-layer chromatography as separation steps. Visible fluorescence from the separated components on chromatoplates was measured directly to obtain fluorescence profiles of the components on the chromatoplates. Several comparisons were made among the shale oil samples as to the relative amounts of 6-, 5-, 4- and 3-ring polycyclic aromatic hydrocarbons. The theoretical and practical analytical aspects of the room temperature phosphorescence of nitrogen heterocycles were investigated. Intense room temperature phosphorescence was obtained from several nitrogen heterocycles when these compounds were absorbed on silica gel. Theoretical explanations were given for the intense phosphorescence. Benzo(f)quinoline and phenanthridine were separated from a shale oil sample by open-column and high performance liquid chromatography, and then identified by room temperature phosphorescence.
