Book Description
Diesel and gasoline powered motor vehicle emissions were quantified through both ambient measurements and source-based emissions measurements. Ambient ultrafine particulate matter was measured and chemically speciated for a source apportionment analysis to identify the vehicular contributions at an urban city in California. The efforts of the Emissions Reduction Plan for Ports and Goods Movement in California have been realized through the comparison of ultrafine particulate matter contributions from old-technology diesel engines during different phases of the regulation implementation between years 2009 and 2010. Volatility of primary organic aerosols from gasoline powered motor vehicles was investigated using a series of thermodenuder experiments and particle evaporation modeling. The behaviors and the compositions of gas- and particle-phase motor vehicle emissions under atmospherically relevant conditions were also examined. These analyses will aid scientists and regulators in properly assessing the current state of vehicular emissions regulations, aid in particulate matter exposure studies, improve the understanding of the characteristics of vehicular emissions, and determine the effects of atmospheric parameters on the production and the partitioning of organic pollutants.

Particulate Emissions from Motor Vehicles

Pages : 400
Book Description
All tailpipes emit a wide variety of liquid- and solid-phase particles. They are omnipresent; but being small and in trace quantities, they are usually emitted unseen - we become aware of them only through the visible testimony of smoke. Particulate emissions engender serious ramifications for public health, amenity and the wider environment. Historically it is diesel engines that have been singled out for stricture, but today this makes less sense, as their particulate emissions are now approaching parity with gasoline engines. For 30 years, the legal requirement has been solely to reduce the total mass of particles emitted, but mass as a toxological indicator is being increasingly questioned, with other metrics proposed, such as: particle size, number and composition. This shift of perspective has far-reaching repercussions for the automotive industry, because new ways of characterising and controlling emissions of particulate will have to be sought. This book aims to distil all the available informatiion into a single treatise.

Book Description
"The combination of scientific and institutional integrity represented by this book is unusual. It should be a model for future endeavors to help quantify environmental risk as a basis for good decisionmaking." â€"William D. Ruckelshaus, from the foreword. This volume, prepared under the auspices of the Health Effects Institute, an independent research organization created and funded jointly by the Environmental Protection Agency and the automobile industry, brings together experts on atmospheric exposure and on the biological effects of toxic substances to examine what is knownâ€"and not knownâ€"about the human health risks of automotive emissions.
Non-exhaust Particulate Emissions from Road Transport An Ignored Environmental Policy Challenge

Pages : 149
Book Description
Non-exhaust emissions of particulate matter constitute a little-known but rising share of emissions from road traffic and have significant negative impacts on public health. This report synthesizes the current state of knowledge about the nature, causes, and consequences of non-exhaust particulate emissions. It also projects how particulate matter emissions from non-exhaust sources may evolve in future years and reflects on policy instrument mixes that can address this largely ignored environmental issue.
Global Sources of Local Pollution
Author: National Research CouncilPublisher: National Academies Press
ISBN: 0309144019
Category : Nature
Languages : en
Pages : 248
Book Description
Recent advances in air pollution monitoring and modeling capabilities have made it possible to show that air pollution can be transported long distances and that adverse impacts of emitted pollutants cannot be confined to one country or even one continent. Pollutants from traffic, cooking stoves, and factories emitted half a world away can make the air we inhale today more hazardous for our health. The relative importance of this "imported" pollution is likely to increase, as emissions in developing countries grow, and air quality standards in industrial countries are tightened. Global Sources of Local Pollution examines the impact of the long-range transport of four key air pollutants (ozone, particulate matter, mercury, and persistent organic pollutants) on air quality and pollutant deposition in the United States. It also explores the environmental impacts of U.S. emissions on other parts of the world. The book recommends that the United States work with the international community to develop an integrated system for determining pollution sources and impacts and to design effective response strategies. This book will be useful to international, federal, state, and local policy makers responsible for understanding and managing air pollution and its impacts on human health and well-being.
