The report reviews NARSTO's recent report on atmospheric science issues associated with management of airborne particulate matter (PM) to achieve air quality standards. NARSTO is a public-private partnership with members from government, utilities, industry, and academe in Canada, Mexico and the United States that coordinates ozone-related atmospheric science research and assessment.
The first part of this book reviews the basics of atmospheric chemistry, radiation transport, and optical spectroscopy before detailing the principles underlying DOAS. The second part describes the design and application of DOAS instruments as well as the evaluation and interpretation of spectra. The recent expansion of DOAS application to the imaging of trace gas distributions by ground, aircraft, and satellite-based instruments is also covered.
The Committee on Ozone-Forming Potential for Reformulated Gasoline was asked whether the existing body of scientific and technical information is sufficient to permit a robust evaluation and comparison of the emissions from motor vehicles using different reformulated gasolines based on their ozone-forming potentials and to assess the concomitant impact of that approach on air-quality benefits of the use of oxygenates within the RFG program. As part of its charge, the committee was asked to consider (1) the technical soundness of various approaches for evaluating and comparing the relative ozone-forming potentials of RFG blends, (2) technical aspects of various air-quality issues related to RFG assessment, and (3) the sensitivity of evaluations of the relative ozone-forming potentials to factors related to fuel properties and the variability of vehicle technologies and driving patterns.
Presents ecology and current environmental studies from an anthropological point of view The Environment in Anthropology presents ecology and current environmental studies from an anthropological point of view. From the classics to the most current scholarship, this text connects the theory and practice in environment and anthropology, providing readers with a strong intellectual foundation as well as offering practical tools for solving environmental problems. Haenn, Wilk, and Harnish pose the most urgent questions of environmental protection: How are environmental problems mediated by cultural values? What are the environmental effects of urbanization? When do environmentalists’ goals and actions conflict with those of indigenous peoples? How can we assess the impact of “environmentally correct” businesses? They also cover the fundamental topics of population growth, large scale development, biodiversity conservation, sustainable environmental management, indigenous groups, consumption, and globalization. This revised edition addresses new topics such as water, toxic waste, neoliberalism, environmental history, environmental activism, and REDD (Reducing Emissions from Deforestation and Forest Degradation), and it situates anthropology in the multi-disciplinary field of environmental research. It also offers readers a guide for developing their own plan for environmental action. This volume offers an introduction to the breadth of ecological and environmental anthropology as well as to its historical trends and current developments. Balancing landmark essays with cutting-edge scholarship, bridging theory and practice, and offering suggestions for further reading and new directions for research, The Environment in Anthropology continues to provide the ideal introduction to a burgeoning field.
The chapters in this book present a snapshot of the state of knowledge of air pollution effects at the beginning of the 21st century. From their different disciplines, a distinguished collection of authors document their understanding of how leaves, trees, and forests respond to air pollutants and climate change. Scenarios of global change and air pollution are described. The authors describe responses of forests to climate variability, tropospheric ozone, rising atmospheric CO2, the combination of CO2 and ozone, and deposition of acidic compounds and heavy metals. The responses to ozone receive particular attention because of increasing concern about its damaging effects and increasing concentrations in rural areas. Scaling issues are addressed - from leaves to trees, from juvenile trees to mature trees, from short-term responses to long-term responses, and from small-scale experiments and observations to large-scale forest ecosystems. This book is one major product of a conference sponsored by the International Union of Forestry Research Organizations, the USDA Forest Service Global Change Northern Stations Program, the Arthur Ross Foundation, NCASI, the Canadian Forest Service, and Michigan Technological University. The conference, held in May 2000 in Houghton, Michigan, USA, was appropriately titled "Air Pollution, Global Change, and Forests in the New Millennium". The Editors, David Karnosky, Kevin Percy, Art Chappelka, Caroline Simpson, and Janet Pikkarainen organized the conference and edited this book.
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.
