This book was released on 2012-12-06 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the combined papers from a NATO sponsored meeting entitled "Mobile Source Emissions Including Polycyclic Organic Species". This meeting was held in Liege, Belgium, from August 30 to September 2, 1982, as an Advanced Research Workshop (ARW). Specialists from 13 countries met to discuss the impacts of fuel type and engine operation on emissions from gasoline and diesel-powered vehicles. The meeting was organized into five sessions: basic studies, biological activity, analytical methods, data bases, engineering and international research programs. The five sessions were each followed by intensive discussions on the important conclusions to be drawn from the data presented. From these session discussions, subcommittee efforts and a final group discussion on all the research results presented, a meeting summary was prepared by the editors that presents the major findings of the conference and gives detailed recommendations for future research. This summary is included at the end of the book. The summary i"nc1udes highlights of data presented, areas of research needs, recommendations for standardization of test parameters and species analyzed, suggested new methodology for characterizing mobile emissions, trends in fuel use including diesel, gasoline, anti-knock additives and blending agents, operation of catalysts, control strategies, implications from both in vivo and in vitro health effects studies, and a presenta tion of the scopeiand direction of several large international programs that are major studies of mobile source performance.

Download or read book Diesel and Gasoline Engine Exhausts and Some Nitroarenes written by IARC Working Group on the Evaluation of Carcinogenic Risks to Humans and published by IARC Monographs on the Evaluat. This book was released on 2015-06-04 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of the IARC Monographs provides evaluations of the carcinogenicity of diesel and gasoline engine exhausts, and of 10 nitroarenes found in diesel engine exhaust: 3,7-dinitrofluoranthene, 3,9-dinitrofluoranthene, 1,3-dinitropyrene, 1,6-dinitropyrene, 1,8-dinitropyrene, 6-nitrochrysene, 2-nitrofluorene, 1-nitropyrene, 4-nitropyrene, and 3-nitrobenzanthrone. Diesel engines are used for transport on and off roads (e.g. passenger cars, buses, trucks, trains, ships), for machinery in various industrial sectors (e.g. mining, construction), and for electricity generators, particularly in developing countries. Gasoline engines are used in cars and hand-held equipment (e.g. chainsaws). The emissions from such combustion engines comprise a complex and varying mixture of gases (e.g. carbon monoxide, nitrogen oxides), particles (e.g. PM10, PM2.5, ultrafine particles, elemental carbon, organic carbon, ash, sulfate, and metals), volatile organic compunds (e.g. benzene, formaldehyde) and semi-volatile organic compounds (e.g. polycyclic aromatic hydrocarbons) including oxygenated and nitrated derivatives of polycyclic aromatic hydrocarbons. Diesel and gasoline engines thus make a significant contribution to a broad range of air pollutants to which people are exposed in the general population as well as in different occupational settings. An IARC Monographs Working Group reviewed epidemiological evidence, animal bioassays, and mechanistic and other relevant data to reach conclusions as to the carcinogenic hazard to humans of environmental or occupational exposure to diesel and gasoline engine exhausts (including those associated with the mining, railroad, construction, and transportation industries) and to 10 selected nitroarenes. -- Back cover.

Download or read book Side reactions in diesel particulate filters written by Matteo Carrara and published by Sudwestdeutscher Verlag Fur Hochschulschriften AG. This book was released on 2011 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diesel particulate matter is widely considered as a possible human carcinogen. Several classes of organic components such as polycyclic aromatic hydrocarbons (PAHs), nitrated PAHs (NPAHs) and aliphatic hydrocarbons can adsorb on the soot surface. Although diesel particulate filters (DPFs) have been designed and implemented to reduce these and other harmful diesel emissions, the particle loaded filters may act as a rection chamber for side reactions whose products could possibly offset the positive effects of the DPF itself. Scope of the present dissertation was to explain to which extent modern DPFs could support the formation of highly toxic and mutagenic NPAHs by nitration of pre-existing PAHs. In addition, the use of biofuels and biofuel blends in different vehicles was investigated with respect to the effects on NPAHs emission.

Download or read book Formation of Nitrated Polycyclic Aromatic Hydrocarbons in Diesel Particulate Filters Laboratory Experiments and Test bench Measurements written by and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The present dissertation investigated the interaction of soot-adsorbed PAH with NO2 both in laboratory model systems and in real diesel engines exhaust. Scope of the experiments was to explain to which extent modern diesel particulate filters (DPFs) could support the formation of highly toxic and mutagenic nitro-polycyclic aromatic hydrocarbons (NPAH) by nitration of pre-existing PAH. Results demonstrated that NPAH formation is possible and actually occurs depending on the operating conditions. In addition, the use of biofuels in different vehicles was investigated with respect to the effects on NPAH emission. In an EURO V truck and in an EURO V diesel car, NPAH concentrations in the exhaust were not significantly different from those of fossil fuel. In an EURO V otto-cycle car and an the EU III A tractor, emissions from biofuels were sensibly lower.
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.
Download or read book Investigation of Nitro organic Compounds in Diesel Engine Exhaust written by John Dane and published by . This book was released on 2010 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Renewable Energy Laboratory upgraded its ReFUEL engine and vehicle testing facility to speciate unregulated gas-phase emissions. To complement this capability, the laboratory contracted with the Colorado School of Mines (CSM) to study the effects of soy biodiesel fuel and a diesel particle filter (DPF) on emissions of polycyclic aromatic hydrocarbons (PAH) and nitro-polycyclic aromatic hydrocarbons (NPAH). CSM developed procedures to sample diesel particulate matter (PM) emissions from raw and diluted exhaust, with and without a DPF. They also developed improved procedures for extracting PAH and NPAH from the PM and quantifying them with a gas chromatograph-electron monochromator mass spectrometer. The study found the DPF generally reduced PAH emissions by 1 to 3 orders of magnitude. PAH conversion was lowest for B100, suggesting that PAHs were forming in the DPF. Orders of magnitude reductions were also found for NPAH emissions exiting the DPF.
