Book Synopsis The Analysis of Particulate and Vapor Phase Polycyclic Aromatic Hydrocarbons in Atmospheric Samples Using Liquid Chromatography with Fluorescence Detection and Gas Chromatography with Mass Spectrometric Detection by : Kathleen P. Duggan
Download or read book The Analysis of Particulate and Vapor Phase Polycyclic Aromatic Hydrocarbons in Atmospheric Samples Using Liquid Chromatography with Fluorescence Detection and Gas Chromatography with Mass Spectrometric Detection written by Kathleen P. Duggan and published by . This book was released on 2001 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polycyclic aromatic hydrocarbons (PAHs) are products of the incomplete combustion of carbonaceous material emanating from many sources including forest fires, furnaces, and gasoline or diesel motor exhausts. Large PAHs have low vapor pressures and readily adsorb on to particulate matter. Particulates may remain in the atmosphere for prolonged periods of time and pose a threat to ecosystems if present at elevated levels. Smaller PAHs, such as naphthalene and fluorene, have relatively high vapor pressures and are more likely to be present in the vapor phase. Thus, it is important to determine PAH levels present in both the vapor phase and the particulate phase. Particulate-bound and vapor phase PAHs were collected at a low-, medium- and high-traffic area in Halifax, N.S. Pressure-assisted solvent extraction and sonication were chosen for extraction of PAHs from filters and polyurethane foams, respectively. HPLC/Fluorescence was the technique chosen for the identification and quantification of PAHs and GC/MS was used to monitor selectively air samples for alkylated PAHs in order to obtain possible fingerprints of the sources of these pollutants.

Book Synopsis Analysis of Nitrated Polycyclic Hydrocarbons, PAH-quinones and Related Compounds in Ambient Air by : Yalan Wang
Download or read book Analysis of Nitrated Polycyclic Hydrocarbons, PAH-quinones and Related Compounds in Ambient Air written by Yalan Wang and published by . This book was released on 1987 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were conducted to characterized airborne particulate extractable organic matter (EOM) with respect to chemical composition and biological activity. It has been well established that the nitrated polycyclic hydrocarbons (nitroPAH) are environmental contaminants. To identify nitro-PAH in ambient air sample, a technique was developed involving introduction of a reducer column into an reversephase high performance liquid chromatography (HPLC) system. Strong fluorescence signals were achieved from nitro-PAH and detected together with u.v. signals for the qualitative and quantitative analysis of nitro-PAH. 2-Nitrotriptycene was synthesized according to published procedures and used as an internal standard. By use of the above technique, 9nitroanthracene, 1-nitropyrene, 7 -nitrobenz (a) anthracene, 6-nitrochrysene and 6-nitrobenzo(a)pyrene were detected in NBS diesel particulate sample. PAH-quinones may be formed from the appropriate PAH's by their photochemical oxidation in the atmosphere. In this study, an analytical method for the identification of PAH-quinones in airborne particulates was developed. The same HPLC system was employed as that for nitro-PAH. 3,6BaP-dione and 7,8-BaP-dione were identified in both CYC extract and DCM extract of an ambient air sample by using the analytical method developed. Since hydroxynitropyrenes have been identified as making a significant contribution to the mutagenicity of airborne particulate matter, this prompted us to investigate one such compound, 1nitropyren-2-ol. This compound was synthesized according to published procedures. 1-Nitropyren2-ol was detected in one of the ambient air samples and in an NBS diesel particulate sample by using our reverse-phase HPLC system monitoring at 546 nm. To provide more data for estimating the photochemical products of 1nitropyrene, the filters coated with 1nitropyrene were exposed either to sunlight or to u.v. light. The breakdown products were analyzed using HPLC. No 1-nitropyren-2-ol was found in the filters exposed in both ways. Further work is needed to identify the breakdown products.

Download or read book Polycyclic Aromatic Hydrocarbons written by Kazuichi Hayakawa and published by Springer. This book was released on 2018-02-05 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book PAHs written by Peter E. T. Douben and published by John Wiley & Sons. This book was released on 2003-07-25 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polycyclic aromatic hydrocarbons (PAHs), or polyarenes, are one of the largest and most structurally diverse class of organic molecules known. High percentages of polyarenes, representing a wide range of molecular sizes and structural types, are present in coal tars and petroleum residues. The major sources of PAHs are crude oil, coal and oil shale. The fuels produced from these fossil sources constitute the primary source of energy for the industrial nations of the world, and the petrochemicals from these raw materials are the basis of the synthetic fibre and plastics industries. PAHs are however, widespread pollutants and their impact on the environment and human health must be monitored and controlled. This book will review and assess our scientific understanding of the ecological exposure and effects PAHs have in different environments and habitats. It will accomplish this by taking the recipients of the pollution in the environment as starting points and working its way back through pathways to access what is required for our understanding of effects and rationale for control. Although this book will concentrate on ecological exposure of PAHs, the general impacts of PAHs on human populations will be touched upon. It is thought to be the first book to focus on the ecological aspects of PAHs.
