Download or read book Evaluation of Emission Control Strategies for the 8 hour Ozone Standard in the Houston and Dallas Areas and a Pilot scale Study of In use Emissions from Heavy duty Diesel Dump Trucks Using a Portable Emissions Monitoring System PEMS written by and published by . This book was released on 2006 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project had two primary objectives. The first objective was to examine the relative effectiveness of potential new emission control measures, primarily from mobile sources, on 1-hour and 8-hour ozone concentrations and population exposure metrics in the Houston and Dallas areas. The second objective was to conduct a pilot-scale study to examine how portable emissions monitoring system (PEMS) technology can be used to characterize exhaust emissions from heavy-duty diesel vehicles and equipment during real-world driving conditions. The overall goal of the research was to provide a foundation for effective transportation and air quality policy decisions in eastern Texas. A total of 38 modeling simulations were conducted to examine a range of emission control strategies.

Download or read book Volatile Organic Compounds in the Atmosphere written by Ralf Koppmann and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every day, large quantities of volatile organic compounds (VOCs) are emitted into the atmosphere from both anthropogenic and natural sources. The formation of gaseous and particulate secondary products caused by oxidation of VOCs is one of the largest unknowns in the quantitative prediction of the earth’s climate on a regional and global scale, and on the understanding of local air quality. To be able to model and control their impact, it is essential to understand the sources of VOCs, their distribution in the atmosphere and the chemical transformations which remove these compounds from the atmosphere. In recent years techniques for the analysis of organic compounds in the atmosphere have been developed to increase the spectrum of detectable compounds and their detection limits. New methods have been introduced to increase the time resolution of those measurements and to resolve more complex mixtures of organic compounds. Volatile Organic Compounds in the Atmosphere describes the current state of knowledge of the chemistry of VOCs as well as the methods and techniques to analyse gaseous and particulate organic compounds in the atmosphere. The aim is to provide an authoritative review to address the needs of both graduate students and active researchers in the field of atmospheric chemistry research.

Download or read book Evaluating Vehicle Emissions Inspection and Maintenance Programs written by National Research Council and published by National Academies Press. This book was released on 2001-12-16 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emissions inspection and maintenance (I/M) programs subject vehicles to periodic inspections of their emission control systems. Despite widespread use of these programs in air-quality management, policy makers and the public have found a number of problems associated with them. Prominent among these issues is the perception that emissions benefits and other impacts of I/M programs have not been evaluated adequately. Evaluating Vehicle Emissions Inspection and Maintenance Programs assesses the effectiveness of these programs for reducing mobile source emissions. In this report, the committee evaluates the differences in the characteristics of motor vehicle emissions in areas with and without I/M programs, identifies criteria and methodologies for their evaluation, and recommends improvements to the programs. Most useful of all, this book will help summarize the observed benefits of these programs and how they can be redirected in the future to increase their effectiveness.

Download or read book Technologies and Approaches to Reducing the Fuel Consumption of Medium and Heavy Duty Vehicles written by National Research Council and published by National Academies Press. This book was released on 2010-07-30 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles evaluates various technologies and methods that could improve the fuel economy of medium- and heavy-duty vehicles, such as tractor-trailers, transit buses, and work trucks. The book also recommends approaches that federal agencies could use to regulate these vehicles' fuel consumption. Currently there are no fuel consumption standards for such vehicles, which account for about 26 percent of the transportation fuel used in the U.S. The miles-per-gallon measure used to regulate the fuel economy of passenger cars. is not appropriate for medium- and heavy-duty vehicles, which are designed above all to carry loads efficiently. Instead, any regulation of medium- and heavy-duty vehicles should use a metric that reflects the efficiency with which a vehicle moves goods or passengers, such as gallons per ton-mile, a unit that reflects the amount of fuel a vehicle would use to carry a ton of goods one mile. This is called load-specific fuel consumption (LSFC). The book estimates the improvements that various technologies could achieve over the next decade in seven vehicle types. For example, using advanced diesel engines in tractor-trailers could lower their fuel consumption by up to 20 percent by 2020, and improved aerodynamics could yield an 11 percent reduction. Hybrid powertrains could lower the fuel consumption of vehicles that stop frequently, such as garbage trucks and transit buses, by as much 35 percent in the same time frame.

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.
