The book looks at efforts to spur social and behavioral changes that affect air quality, the effectiveness of market-based instruments for air quality regulation, and many other aspects of the issue. Rich in technical detail, this book will be of interest to all those engaged in air quality management: scientists, engineers, industrial managers, law makers, regulators, health officials, clean-air advocates, and concerned citizens.
Book Synopsis The Ongoing Challenge of Managing Carbon Monoxide Pollution in Fairbanks, Alaska by : National Research Council
Download or read book The Ongoing Challenge of Managing Carbon Monoxide Pollution in Fairbanks, Alaska written by National Research Council and published by National Academies Press. This book was released on 2002-08-22 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon monoxide (CO) is a toxic air pollutant produced largely from vehicle emissions. Breathing CO at high concentrations leads to reduced oxygen transport by hemoglobin, which has health effects that include impaired reaction timing, headaches, lightheadedness, nausea, vomiting, weakness, clouding of consciousness, coma, and, at high enough concentrations and long enough exposure, death. In recognition of those health effects, the U.S. Environmental Protection Agency (EPA), as directed by the Clean Air Act, established the health-based National Ambient Air Quality Standards (NAAQS) for CO in 1971. Most areas that were previously designated as "nonattainment" areas have come into compliance with the NAAQS for CO, but some locations still have difficulty in attaining the CO standards. Those locations tend to have topographical or meteorological characteristics that exacerbate pollution. In view of the challenges posed for some areas to attain compliance with the NAAQS for CO, congress asked the National Research Council to investigate the problem of CO in areas with meteorological and topographical problems. This interim report deals specifically with Fairbanks, Alaska. Fairbanks was chosen as a case study because its meteorological and topographical characteristics make it susceptible to severe winter inversions that trap CO and other pollutants at ground level.
Book Synopsis Principles of Air Quality Management by : Roger D. Griffin
Download or read book Principles of Air Quality Management written by Roger D. Griffin and published by CRC Press. This book was released on 1994-07-13 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Principles of Air Quality Management presents the fundamental principles that make up the broad field of air quality, pollution, and management. It is intended for those who have a general interest in the field, as well as those who have been involved in possibly only one or two of the specific aspects of air quality management. The book provides an understanding of the principles that govern our ability to manage air quality resources. It brings together in one volume current information on clean fuels, control technology, health effects, regulations, indoor air quality, global concerns, sources of criteria and hazardous air pollutants, atmospheric dispersion and modeling, air quality standards, risk assessments of air toxics, and trends. Beginning with the make-up of air and definitions of air and air pollution, this book outlines the history of air quality management, discussing emissions, standards, classifications of pollutants, and the production of secondary air pollution or photochemical smog.The discussion continues with the health effects of air pollutants and those that are considered toxic or hazardous, and the effects of those contaminants on the human body. Air pollutant damage to materials and vegetation, the standards of acceptable air quality from a health impacts outlook, and the techniques for measuring air quality are also reviewed. Air contaminant sources are approached from anthropogenic, geogenic, and biogenic viewpoints. From local, regional, and global perspectives, the book examines how contaminants are dispersed between sources and receptors. From these studies, an evaluation is made of the different models used to calculate dispersion and of the models used to predict ambient air quality. Federal laws and regulations, as well as regional perspectives, are summarized and evaluated. Control technologies available for both stationary sources and mobile sources are reviewed. From these sources, management options for limiting emissions and optimizing air pollutant strategies are analyzed. Also included is the latest data from the Auto/Oil Program on the impact of fuel reformulation on engine tailpipe emissions, the conclusions of the MECCA group on global warming, the findings of the California Healthy Building Pilot Study on indoor air quality, and the requirements for federal permits under the Clean Air Act Amendments. Global air quality concerns, relative global emissions, and alternative views are evaluated from a management options perspective. The book concludes with a presentation of indoor air quality and future trends in air quality management approaches, as well as their limitations.
Book Synopsis Air Pollution by : John B. Stephenson
Download or read book Air Pollution written by John B. Stephenson and published by DIANE Publishing. This book was released on 2005-11 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power plants emit pollutants have been linked to negative health effects. In 2003, 2 new power plants began operations 3 miles south of the U.S.-Mexico border near Imperial County (IC), CA. Although these plants export most of the elec. they produce to the U.S., they are not required to meet any U.S. or CA emission standards. This report determines: (1) how emissions from the 2 plants compare with emissions from recently permitted plants in CA & emissions from sources in IC, & what emissions standards they would be subject to if they were located in IC; (2) the health impacts of emissions from the plants on IC residents; & (3) options avail. to U.S. policymakers to ensure that emissions from these plants do not adversely affect the health of IC residents.

Available in PDF, EPUB and Kindle. Book excerpt: Urban air pollution and climate are closely connected due to shared generating processes (e.g., combustion) for emissions of the driving gases and aerosols. They are also connected because the atmospheric lifecycles of common air pollutants such as CO, NOx and VOCs, and of the climatically important methane gas (CH4) and sulfate aerosols, both involve the fast photochemistry of the hydroxyl free radical (OH). Thus policies designed to address air pollution may impact climate and vice versa. We present calculations using a model coupling economics, atmospheric chemistry, climate and ecosystems to illustrate some effects of air pollution policy alone on global warming. We consider caps on emissions of NOx, CO, volatile organic carbon, and SOx both individually and combined in two ways. These caps can lower ozone causing less warming, lower sulfate aerosols yielding more warming, lower OH and thus increase CH4 giving more warming, and finally, allow more carbon uptake by ecosystems leading to less warming. Overall, these effects significantly offset each other suggesting that air pollution policy has a relatively small net effect on the global mean surface temperature and sea level rise. However, our study does not account for the effects of air pollution policies on overall demand for fossil fuels and on the choice of fuels (coal, oil, gas), nor have we considered the effects of caps on black carbon or organic carbon aerosols on climate. These effects, if included, could lead to more substantial impacts of capping pollutant emissions on global temperature and sea level than concluded here. Caps on aerosols in general could also yield impacts on other important aspects of climate beyond those addressed here, such as the regional patterns of cloudiness and precipitation.

Available in PDF, EPUB and Kindle. Book excerpt: Air pollution throughout the United States has changed dramatically over the past 50 years in response to numerous initiatives to protect public health. The improved efficiency of motor vehicles and adoption of stricter emission policies on coal-fired power plants are two of the reasons concentrations of criteria air pollutants have decreased. Despite nationwide reductions in most pollutant emissions, many urban regions throughout the United States still exceed unhealthy levels of criteria air pollutants. The underlying causes of these exceedances are difficult to determine as they may be the result of unidentified sources, certain meteorological conditions or changes to ambient pollutant concentrations that may alter the formation of secondary pollutants. In order to develop plans that manage these air pollution episodes, accurate tools that are used to resolve the underlying sources and chemical pathways are required. This dissertation describes three studies that improve our understanding of the causes of modern air pollution problems and provide insights that are useful for the development of the next generation air pollution abatement strategies. The first study explores the effectiveness of historical ozone control strategies by updating the calculation of the Maximum Incremental Reactivity (MIR) scale that predicts ozone production from volatile organic compounds (VOCs). Inputs to the MIR calculations were modernized from 1988 atmospheric conditions to 2010 conditions by accounting for changes in meteorology, emission rates, and background concentrations. The calculations show that the median MIR values across thirty nine cities in the United States decreased by approximately 20% due to the impact of emissions control programs on the atmospheric composition and updates in meteorological variables including temperature, humidity, and boundary layer height. Although the absolute MIR values decreased, the sorted MIR rank of each specific VOC did not change strongly compared to the original rankings calculated using 1988 conditions. These findings indicate that past decisions about ozone control strategies remain valid today and the MIR scale continues to provide relevant guidance for policy makers. The second study evaluates an updated version of the SAPRC chemical mechanism for the prediction of ambient ozone and peroxy-radical concentrations. The SAPRC16 mechanism represents more compounds explicitly and includes a new lumping scheme to improve toxics and SOA precursors compared to the previous SAPRC07 and SAPRC11 mechanisms. SAPRC16 was applied under ambient conditions in cities spanning the United States in order to determine if the improved performance observed during the simulation of smog chamber experiments translated to the real atmosphere. Concentrations of ozone, hydroxyl radical (OH) and hydroperoxyl (HO2) radical were predicted with SAPRC16 and SAPRC11, and compared to measured values. It was generally observed that SAPRC16 predicts slightly lower ozone concentrations than SAPRC11 in NOx rich urban centers. Predictions from SAPRC11 are in better agreement with the measurements in the western United States; however, SAPRC16 outperforms SAPRC11 in some eastern and southern U.S. cities. Ozone concentrations predicted by SAPRC16 and SAPRC11 diverged more as emissions decreased suggesting that the two mechanisms will predict different outcomes from increasingly stringent future emissions control programs. A box model analysis showed that the SAPRC16 mechanism quenches ozone production earlier than SAPRC11 as NOx concentrations increase (yielding decreased VOC/NOx ratios). This could be caused by more detailed HO2+RO2 reactions and RO2 isomerization reactions in SAPRC16 that compete with the HO2+NO reaction. The predictions of OH and HO2 were also evaluated for the two mechanisms using measurements from the CalNex field study in Pasadena. SARPC11 and SAPRC 16 prediction of OH are similar and within EPA criteria for mean fractional error (
