This book was released on 2013 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the most up-to-date research and information regarding the origin, chemistry, fate and health impacts of airborne particulate matter in urban areas, a topic which has received a great deal of attention in recent years due to documented relationships between exposure and health effects such as asthma. With internationally recognised researchers and academics presenting their work and key concepts and approaches from a variety of disciplines, including environmental and analytical chemistry, biology, toxicology, mineralogy and the geosciences, this book addresses the topic of urban airborne particulate matter in a comprehensive, multidisciplinary manner. Topics and research addressed in the book range from common methodological approaches used to sample and analyse the composition of airborne particulates to our knowledge regarding their potential to impact human health and the various policy approaches taken internationally to regulate particulate matter levels.
Book Synopsis Polycyclic Aromatic Hydrocarbons by : Huizhong Shen
Download or read book Polycyclic Aromatic Hydrocarbons written by Huizhong Shen and published by Springer. This book was released on 2016-03-26 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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%.

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.
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.
