Download or read book Urban Climates written by T. R. Oke and published by Cambridge University Press. This book was released on 2017-09-14 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban Climates is the first full synthesis of modern scientific and applied research on urban climates. The book begins with an outline of what constitutes an urban ecosystem. It develops a comprehensive terminology for the subject using scale and surface classification as key constructs. It explains the physical principles governing the creation of distinct urban climates, such as airflow around buildings, the heat island, precipitation modification and air pollution, and it then illustrates how this knowledge can be applied to moderate the undesirable consequences of urban development and help create more sustainable and resilient cities. With urban climate science now a fully-fledged field, this timely book fulfills the need to bring together the disparate parts of climate research on cities into a coherent framework. It is an ideal resource for students and researchers in fields such as climatology, urban hydrology, air quality, environmental engineering and urban design.
Download or read book Transportation and the Environment written by Gabriela Ionescu and published by CRC Press. This book was released on 2017-03-03 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: This title includes a number of Open Access chapters. This new book takes a nuanced look at building a sustainable transportation infrastructure and provides an overview of the harmful effect of various modes of transportation on the environment. The environmental impact of transportation is significant. Transportation is a major user of energy, it burns most of the world's petroleum, and is the fastest-growing contributor to carbon dioxide emissions. Although environmental regulations in many countries have reduced the individual vehicle's emissions, this has been offset by an increase in vehicles on the road and airways.
Download or read book Air Pollution and Urban Structure Linkages written by Miguel Cárdenas Rodríguez and published by . This book was released on 2015 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This paper investigates the relationship between local air pollution and urban structure with an emphasis on urban fragmentation. Using a unique dataset of 249 Large Urban Zones (LUZ) across Europe, a Bayesian Model Averaging selection method is employed to empirically identify the determinants of within-LUZ concentration of three air pollutants: NO2, PM10 and SO2 for the year 2006. Several indices of land use are considered among possible determinants. These are supplemented by a dataset on various economic, demographic and meteorological variables that can explain the variation of air pollution. The results of this econometric analysis support the hypothesis that urban structure has significant effects on pollution concentration. In particular, they suggest that fragmented urban areas experience higher concentrations of NO2 and PM10 and that densely populated urban areas suffer from higher SO2 concentration. The findings suggest that policies favouring continuous urban areas may result in environmental improvements
Download or read book Rethinking the Ozone Problem in Urban and Regional Air Pollution written by National Research Council and published by National Academies Press. This book was released on 1992-02-01 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite more than 20 years of regulatory efforts, concern is widespread that ozone pollution in the lower atmosphere, or troposphere, threatens the health of humans, animals, and vegetation. This book discusses how scientific information can be used to develop more effective regulations to control ozone. Rethinking the Ozone Problem in Urban and Regional Air Pollution discusses: The latest data and analysis on how tropospheric ozone is formed. How well our measurement techniques are functioning. Deficiencies in efforts to date to control the problem. Approaches to reducing ozone precursor emissions that hold the most promise. What additional research is needed. With a wealth of technical information, the book discusses atmospheric chemistry, the role of oxides of nitrogen (NOx) and volatile organic compounds (VOCs) in ozone formation, monitoring and modeling the formation and transport processes, and the potential contribution of alternative fuels to solving the tropospheric ozone problem. The committee discusses criteria for designing more effective ozone control efforts. Because of its direct bearing on decisions to be made under the Clean Air Act, this book should be of great interest to environmental advocates, industry, and the regulatory community as well as scientists, faculty, and students.

Download or read book Air Quality in the Mexico Megacity written by L. Molina and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, experts in atmospheric sciences, human health, economics, social and political sciences contribute to an integrated assessment of the complex elements needed to structure air quality policy in the 21st century. The analysis is developed through a case study of the Mexico City Metropolitan Area - one of the world's largest megacities in which air pollution grew unchecked for decades. The international research team is led by Luisa T. and Mario J. Molina, Nobel Laureate in Chemistry. Improvements in Mexico City's air quality in the last decade testifies to the power of determined and enlightened policy making, and throws into relief the tough problems that remain to be solved. The volume's first six chapters, including the contributions of over 50 distinguished scholars from Mexico and the US, outline the fundamental areas of knowledge policy makers must accommodate. The message is that only good science and well-chosen technologies can direct the way to corrective regulatory measures; but without strong commitment from government, no amount of science or technology can help.
Download or read book Air Quality in Cities written by Nicolas Moussiopoulos and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban areas are major sources of air pollution. Pollutant emissions affecting air quality in cities are considered to have adverse consequences for human health. Public and government concern about environmental issues arising from urban air pollution has increased over the last decades. The urban air pollution problem is widespread throughout the world and it is important to find ways of eliminating or at least reducing the risks for human health. The fundamentals of the physical and chemical processes occurring during air pollutant transport in the atmosphere are nowadays understood to a large extent. In particular, modelling of such processes has experienced a remarkable growth in the last decades. Monitoring capabilities have also improved markedly in the most urban areas around the world. However, neither modelling nor monitoring can solve urban air pollution problems, as they are only a first step in improving useful information for future regulations. The defining of efficient control strategies can not be achieved without a clear knowledge of the complete pollution process, i.e. emission, atmospheric transport and transformation, and deposition at the receptor. Improving our ability to establish valid urban scale source-receptor relation ships has been the objective of SA TURN, one of the 14 subprojects of EURO TRAC-2. Similar to the other subprojects of this co-ordinated environmental pro ject within the EUREKA initiative, SA TURN brought together international groups of scientists to work on problems directly related to atmospheric chemistry and physics. The present volume summarises the scientific results of SATURN.

Download or read book WHO global air quality guidelines written by Weltgesundheitsorganisation and published by World Health Organization. This book was released on 2021-09-07 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of these updated global guidelines is to offer health-based air quality guideline levels, expressed as long-term or short-term concentrations for six key air pollutants: PM2.5, PM10, ozone, nitrogen dioxide, sulfur dioxide and carbon monoxide. In addition, the guidelines provide interim targets to guide reduction efforts of these pollutants, as well as good practice statements for the management of certain types of PM (i.e., black carbon/elemental carbon, ultrafine particles, particles originating from sand and duststorms). These guidelines are not legally binding standards; however, they provide WHO Member States with an evidence-informed tool, which they can use to inform legislation and policy. Ultimately, the goal of these guidelines is to help reduce levels of air pollutants in order to decrease the enormous health burden resulting from the exposure to air pollution worldwide.
Download or read book Urban Form and Air Quality in U S Metropolitan and Megapolitan Areas written by Bradley James Frank Bereitschaft and published by . This book was released on 2011 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The spatial form, or morphology, of urban areas may significantly affect the anthropogenic production of air pollutants. This dissertation explores the relationships between air quality and urban form at the metropolitan and megapolitan (multi-metropolitan) scale. Urban form was quantified for 86 metropolitan and 19 megapolitan areas using both pre-existing sprawl indices and multiple spatial metrics derived from remotely sensed landcover data. Air quality was assessed by measuring several key air pollutants, including the ambient concentration of ozone (O3), the non-point source emissions of the two O3 precursors nitrogen oxides (NOx) and volatile organic compounds (VOCs), the ambient concentration and non-point source emissions of fine particulate matter (PM2.5) and coarse particulate matter (PM10), and the mobile emissions of carbon dioxide (CO2). The ambient concentrations of air pollutants were averaged over the 5-year period 1998 to 2002. While controlling for industrial emissions, climate, population and geographic area, multiple linear regression was used to evaluate the degree of association between measures of urban form and air quality. The results suggest that urban form has a measurable impact on both the non-point source emission and ambient concentration of air pollution. Urban areas that exhibited more "sprawl-like" urban forms (i.e. lower residential density, less street network connectivity, less contiguous urban development) generally had higher non-point source emissions and/ or ambient concentrations of air pollution. Pre-existing sprawl indices were most significantly associated with ambient concentrations, while two spatial-metrics based measures of urban structure, urban "continuity" and urban "shape complexity," were most significantly associated with non-point source emissions. The relationships between measures of urban form calculated using spatial metrics and air pollution were most significant at the metropolitan scale. The extent of the urban area (i.e. high versus low urban threshold), however, did not significantly affect the associations between urban form, as assessed using spatial metrics, and air pollution. Understanding the relationships between urban form and air quality is an important step in identifying effective urban land use configurations and developing healthier cities."--Abstract from author supplied metadata.

Download or read book Urban Pollution and Changes to Materials and Building Surfaces written by Peter Brimblecombe and published by World Scientific. This book was released on 2015-11-23 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollution damages materials, but it has changed dramatically in the past century, with a reduction in the concentration of corrosive primary pollutants in urban atmospheres. At the same time, architectural styles and types of materials have changed, as we have moved to more organically rich, photochemically active atmospheres. Contemporary pollutants have a greater potential to degrade organic coatings and polymers, which are of great importance to modern structures.Urban Pollution and Changes to Materials and Building Surfaces examines a range of materials, discussing the ways in which they are likely to be damaged by contemporary urban pollutants, with an emphasis on the effects of air pollution. A chapter on graffiti is also included.The wide scope covered means that this volume is suitable for readers from a broad background. It should be of interest to scientists and policymakers dealing with the effects of urban pollution, as well as undergraduate and graduate students working in this area.This book, with its wealth of information, is of exceedingly good value for readers who seek to understand more on the changes of materials and building surfaces by urban pollution.
