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 Urban Air Pollution in Megacities of the World written by John P. Allen and published by Wiley-Blackwell. This book was released on 1993-01-18 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Urban Air Pollution in Mega Cities of the World d report assesses air quality in 20 of the world's megacities (defined for the purposes of this book as cities with a population of 10 million or more by the year 2000). The report highlights the air quality problems associated with urbanization. These problems are of increasing importance due to projected growth in the urban pollution world-wide and thus the potential increase in the number of people exposed. The issues raised apply not only to current mega-cities but to most rapidly developing urban areas. The cities are; New York City, Los Angeles, New Delhi, Calcutta, Bombay, Cairo/Giza, Karachi, Moscow, London, Seoul, Metro Manila/Quezon City, Beunos Aries, Rio de Janeiro, Sao Paulo, Tokyo/Yokohama, Beijing, Shanghai, Jakarta, Bangkok and Mexico City.

Download or read book Urban Air Pollution and Forests written by Mark E. Fenn and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present, roughly half of the world's population lives in urban centers. There are now more than 20 cities with a population of over 10 million inhabitants, compared to less than 5 about 50 years ago. This tendency toward urbanization is expected to continue, particularly in the developing world. A consequence of this growing trend is that millions of people are being exposed to harmful levels of urban air pollutants caused mainly by emissions from motor vehicles and from industrial and domestic activities involving the combustion of fossil fuels. The driving force for the design and implementation of emission control strate gies aimed at improving air quality has been the protection of the health of the population in urban centers. There are, however, other consequences of the pres ence of air pollutants besides the direct effect on human health. Reduced visibil ity, damage to monuments and buildings, and many other such consequences indirectly affect our quality of life. Another set of consequences involves damage to ecological systems. In fact, the nature of "photochemical smog" was first uncovered in the 1950s in connection with observations of its harmful effects on crops and plants in the vicinity of Los Angeles.
Download or read book An Approach to Assessing the Technical Feasibility and Market Potential of a New Automotive Device written by Rand Zero Emission Fuel Saver Study Team and published by Rand Corporation. This book was released on 2007 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Save the World Air (STWA) has developed magnet-based devices, including its Zero Emission Fuel Saver (ZEFS), that it claims can improve vehicle fuel economy and reduce emissions. These devices are designed to be fitted as original equipment onto internal combustion engines or to be retrofitted onto existing engines. STWA asked the RAND Corporation to help develop a plan for assessing the technical basis required for successful commercialization of ZEFS. STWA also sought RAND's advice in examining potential market opportunities for ZEFS. This report summarizes RAND's analysis of these two issues, concluding the following. Application of magnetic fields has not been shown in the literature to lower the viscosity of automotive fuels. Along with empirical testing, establishing a theoretical basis underlying the effect of magnetic fields on fuel viscosity, surface tension, and atomization might provide useful information for developing and evaluating magnetic field-based fuel treatment devices. So far, the test results for use of the device are, at best, mixed. Should further laboratory analysis and in-use testing provide clearer and more positive outcomes, the market potential for the device will depend significantly on the advances realized from other technologies and regulatory policies and on its cost-effectiveness relative to other outcomes.

Available in PDF, EPUB and Kindle. Book excerpt: Air pollution has become part of the daily existence of many people who work, live and use the streets in Asian cities. Each day millions of city dwellers breathe air polluted with concentrations of chemicals, smoke and particles that dramatically exceed World Health Organization guideline values. Deteriorating air quality has resulted in significant impacts on human health and environment in Asia. This book provides a comprehensive and comparative assessment of the current status and challenges in urban air pollution management in 20 cities in the Asian region. It examines the effects on human health and the environment and future implications for planning, transport and energy sectors. National and local governments have begun to develop air quality management strategies to address the deterioration in urban air quality; however, the scope and effectiveness of such strategies vary widely. This book benchmarks these air quality management strategies, examines successes and failures in these cities and presents strategies for improving air quality management in cities across Asia and the rest of our rapidly urbanizing world. Information on air quality in Asia is clearly presented with easy-to-read city profiles, tables and graphs. This is an essential resource for all those concerned with urban air quality management, not just in Asia but in cities across our rapidly urbanizing world. Cities covered Bangkok, Beijing, Busan, Colombo, Dhaka, Hanoi, Ho Chi Minh City, Hong Kong, Jakarta, Kathmandu, Kolkata, Metro Manila, Mumbai, New Delhi, Seoul, Shanghai, Singapore, Surabaya, Taipei and Tokyo
Download or read book Urban Air Pollution written by Ivo Allegrini and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the proceedings of a NATO Advanced Research Workshop which was also financially supported by the National Research Council of Italy. The Workshop was held from October 9 to 15, 1994, at the Centro Ettore Maiorana in Erice, Italy. Over 40 researchers from a wide variety of fields attended the Workshop, which brought to attention the ongoing research on various phenomena related to urban air pollution. The presence of high levels of atmospheric pollutants in the air of several urban centres of developed and developing countries causes a great concern among authorities and public opinion. Some 20% of the European population live in cities of more than 500,000 inhabitants and about 40% in cities of more than 50,000. Since exceedance of the Air Quality Guidelines has been observed to occur worldwide, a great effort has been addressed to the control of primary pollutants, but many problems related to secondary pollutants such as nitrogen containing species (nitrogen oxides, nitric and nitrous acid, ni trates) and photochemical oxidants (ozone, PAN and others) are far from being solved. The importance of atmospheric chemistry in understanding the processes occurring in urban atmospheres has been well recognised, thus there is a strong need to exchange experiences and results from urban centres in different Countries. Indeed, atmospheric pollution is very much dependent on the type of emissions which are very different according to the economic development of the urban centre under consideration.

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 Air Pollution Science for the 21st Century written by J. Austin and published by Elsevier. This book was released on 2002-10-31 with total page 687 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acid rain, photochemistry, long-range transport of pollutants, greenhouse gas emissions and aerosols have dominated tropospheric air pollution for the last 30 years of the 20th century. At the start of the 21st century, acid rain is subject to planned improvement in Europe and North America, but is still a growing problem in Asia. Tropospheric ozone is understood much better, but the problem is still with us, and desirable levels are difficult to achieve over continental Europe. The heterogeneous chemistry that is responsible for ozone depletion in the stratosphere is now reasonably clear, but there is on-going interest in the sources and sinks of CFC (chlorofluorocarbon) replacements in the troposphere. There is also increasing interest in indoor air quality, and the origin and health implications of atmospheric particles. Perhaps most important on a global perspective, intensive research has not yet determined the relationship between greenhouse gases, aerosols and surface temperature. The climactic implications of these are now more urgent than ever.This book, the first in the Developments in Environmental Science series, consists of a collection of authoritative reviews and essays on the science and application of air pollution research at the start of this new century.
Download or read book Health in Megacities and Urban Areas written by Alexander Krämer and published by Springer Science & Business Media. This book was released on 2011-07-06 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diverse driving forces, processes and actors are responsible for different trends in the development of megacities and large urban areas. Under the dynamics of global change, megacities are themselves changing: On the one hand they are prone to increasing socio-economic vulnerability due to pronounced poverty, socio-spatial and political fragmentation, sometimes with extreme forms of segregation, disparities and conflicts. On the other hand megacities offer positive potential for global transformation, e.g. minimisation of space consumption, highly effective use of resources, efficient disaster prevention and health care options – if good strategies were developed. At present in many megacities and urban areas of the developing world and the emerging economies the quality of life is eroding. Most of the megacities have grown to unprecedented size, and the pace of urbanisation has far exceeded the growth of the necessary infrastructure and services. As a result, an increasing number of urban dwellers are left without access to basic amenities like clean drinking water, fresh air and safe food. Additionally, social inequalities lead to subsequent and significant intra-urban health inequalities and unbalanced disease burdens that can trigger conflict and violence between subpopulations. The guiding idea of our book lies in a multi- and interdisciplinary approach to the complex topic of megacities and urban health that can only be adequately understood when different disciplines share their knowledge and methodological tools to work together. We hope that the book will allow readers to deepen their understanding of the complex dynamics of urban and megacity populations through the lens of public health, geographical and other research perspectives.

Download or read book Scaling Urban Environmental Challenges written by Peter J. Marcotullio and published by Earthscan. This book was released on 2012 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Think globally, act locally? emphasizes the importance of scale in dealing with environmental challenges, but not how to factor it in. This major new book focuses on the spatial dimensions of urban environmental burdens, showing how important it is to take these into account when pursuing environmental justice and good governance - whether in the context of the sanitary risks of slum living, the pollution of uncontrolled industrialization and motorization, or the enormous ecological footprints of affluent urban lifestyles. Written by leading experts in the fields of urban development and environmental planning, the book reviews the urban environmental shifts that have shaped today's challenges, and examines conditions and problems in the urban centres of low-, middle- and high-income countries. Case studies address such economically diverse cities as Accra, New Delhi, Mexico City and Manchester, while thematic chapters explore issues including water, sanitation and transportation. The book concludes by exploring and analysing different scales of governance. The editors argue that we should not rely solely on local governance to address local burdens like poor sanitation, nor depend only on global governance for global challenges such as greenhouse gas emissions, but that scale is crucial in both understanding the problems and devising successful responses.
