Book Description
The Air Quality Facility of the John A. Volpe National Transportation Systems Center is providing support to the Emissions Division of the Federal Aviation Administration's Office of Environment and Energy (AEE-300). As part of this support, the Air Quality Facility is conducting a comprehensive review of past research in the area of aviation- related particulate matter. The purpose of this literature review is to allow an informed decision to be made on a possible first-order approximation to predict the mass of particulate emissions from aircraft until such time that measured data are available for most aircraft. Available references included in this report were collected from public and private libraries, technical journals, project reports, electronic literature searches, interviews, and other key sources. It should be noted that the literature review is not all- inclusive and that emphasis was placed on information concerning measured mass data from aircraft. Following the literature findings, a first order approximation methodology is suggested to estimate the mass of particulate matter (PM) emitted from aircraft based on available data.

Book Description
"TRB's Airport Cooperative Research Program (ACRP) Report 97: Measuring PM Emissions from Aircraft Auxiliary Power Units, Tires, and Brakes presents the results of a comprehensive test program designed to measure particulate matter (PM) emissions from auxiliary power units and from tires and brakes during the landing phase of operations of in-service commercial aircraft. The research results are designed to provide a significant contribution to the characterization of emissions from these sources with the goal of helping airports improve the accuracy of their PM emissions inventories."--Publisher's description.

Book Description
New National Ambient Air Quality Standards for airborne particles smaller than 2.5 micrometers, called PM2.5, were issued by the U.S. Environmental Protection Agency (EPA) amidst scientific uncertainty and controversy. In response to a request from Congress, Research Priorities for Airborne Particulate Matter, the first of four books in a series, offers a conceptual framework for an integrated national program of particulate-matter research, identifies the 10 most critical research needs linked to key policy-related scientific uncertainties, and describes the recommended timing and estimated costs of such research. The committee concludes that EPA should devote more resources to investigating the relationships between fixed-site outdoor monitoring data and actual human breathing-zone exposures to ambient particulate matter and to identifying the most biologically important constituents and characteristics of particulate matter through toxicological studies. The recommended research activities are critical to determining actual exposures of human subpopulations most susceptible to harm from the most hazardous constituents of particulate matter. Future research will be an investment in public health and a means to ensure that resources spent on control technology and regulatory compliance will have a reasonable probability of success.

Book Description
In the effort to reduce the scientific and technical uncertainties over regulation of airborne particulate matter in the United States, Research Priorities for Airborne Particulate Matter: II. Evaluating Research Progress and Updating the Portfolio, the second book in a four-part series requested by Congress, describes the plans of the committee to monitor the progress of the research on particulate matter conducted by the U.S. Environmental Protection Agency (EPA), other federal and state government agencies, and nongovernmental organizations. The book also reviews and updates the committee's portfolio of recommended research in its first volume, Research Priorities for Airborne Particulate Matter: I. Immediate Priorities and a Long-Range Research Portfolio (NRC, 1998). The committee substantially revised two of the ten high-priority research areas recommended in Part I. Part II notes that Congress, EPA, and the scientific community have given strong support to the committee's recommendations and have implemented substantial changes in research efforts in response to Part I of the series. One important research area-studies of the effects of long-term exposure to particulate matter and other major air pollutants-however, does not appear to be underway or planned.

Book Description
"The UMR Mobile Aerosol Sampling System (MASS) has measured the particulate matter (PM) emissions from commercial aircrafts during the routine takeoff operation within 100m of a runway and 200m of a taxiway at a major US airport for two days in September 2004. The emissions were measured with 1s time resolution using a differential mobility spectrometer (DMS500). The plumes were measured for 2 days, from over 400 commercial aircrafts, ranging from 717's, 767's, MD-88's, to Turboprop's ... In order to interpret these PM data it is important to be able to uniquely identify a given aircraft with a specific emission plume. As is common at many airports departure frequency varies throughout the day. At high departure frequencies, the data gathered cannot be attributed to any specific single aircraft since the emission plumes arriving at the sampling system are convoluted by overlapping departures and from up;wind aircraft stopping and starting while taxiing forward in a line towards the number one departure slot. The data presented here are "first of a kind" PM measurements of advective plumes from commercial aircraft. Although it is planned to eventually interpret high frequency departure data, in this thesis only low frequency departure data specifically attributable to given aircraft will be studied"--Abstract, leaf iii.

Book Description
In 1997, the U.S. Environmental Protection Agency (EPA) established regulatory standards to address health risks posed by inhaling tiny particles from smoke, vehicle exhaust, and other sources. At the same time, Congress and the EPA began a multimillion dollar research effort to better understand the sources of these airborne particles, the levels of exposure to people, and the ways that these particles cause disease. To provide independent guidance to the EPA, Congress asked the National Research Council to study the relevant issues. The result was a series of four reports on the particulate-matter research program. The first two books offered a conceptual framework for a national research program, identified the 10 most critical research needs, and described the recommended timing and estimated costs of such research. The third volume began the task of assessing initial progress made in implementing the research program. This, the fourth and final volume, gauged research progress made over a 5-year period on each of the 10 research topics. The National Research Council concludes that particulate matter research has led to a better understanding of the health effects caused by tiny airborne particles. However, the EPA, in concert with other agencies, should continue research to reduce further uncertainties and inform long-term decisions.
