Book Description
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.

Book Description
Human-induced environmental change is to be found throughout the world, but there are areas that scientists consider to be "critical regions" - regions that are particularly vulnerable to or suffering from environmental degradation. In this volume nine such "critical environmental regions" (Amazonia, the Aral Sea basin, the middle mountains of Nepal, Kenya's Ukambani region, the US Southern High Plains, the Mexico Basin, the North Sea, the Ordos Plateau of China, and the eastern Sundaland region of South-East Asia) are examined as case-studies. In chapter one the authors provide a detailed look into the concepts of environmental criticality and endangerment and propose formal definitions. The nine regional studies that follow in the subsequent chapters serve to translate the conceptual framework into the physical and social realities of each area. The case-studies make available an up-to-date synthesis of vast amounts of inaccessible data, and as such will be valuable to scholars and policy makers interested in specific areas of the world and others interested in regional comparisons. Anyone concerned with global environmental change, criticality, human-environment interactions, and how societies in different regions have responded to environmental degradation will find much that is new and important in this pioneering, innovative study.

Book Description
With a population of more than eighteen million people, Mexico City is a major metropolitan area where the effects of urban development on air quality are of immediate concern. Air pollution exposures and effects on forests in the Mexico City Air Basin are in many respects similar to those reported in the Los Angeles, California Air Basin. Studies of air pollution impacts on forests in these two regions may serve as models for urban areas all over the world. Although scientists have studied air pollution and its effects on forests and vegetation in the Mexico City Air Basin for years, this book reviews and synthesizes this body of work for the first time. This synthesis is particularly valuable as air pollution increases at an alarming rate along with global urbanization. A thorough discussion of regional geology, climate and hydrology, historical natural resource utilization, and sociological factors provide the context for evaluating air pollution impacts on the highly valued forests surrounding this megacity. The environmental and ecological consequences of chronic exposure to biologically important pollutants are considered in various case studies. Finally, the editors discuss the state of air pollution research in the Mexico City Air Basin and the outlook for the health and sustainability of forests within the Basin.

Book Description
The steady growth in the number of vehicles on the road, heavy reliance on coal, use of dirty fuels for residential combustion, and extensive open burning are some of the major factors leading to the progressive deterioration of air quality in developing countries in Asia. And despite efforts to establish and implement air quality measurement syste

Book Description
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.

Book Description
The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Book Description
The understanding that some pesticides are more hazardous than others is well established. Recognition of this is reflected by the World Health Organization (WHO) Recommended Classification of Pesticides by Hazard, which was first published in 1975. The document classifies pesticides in one of five hazard classes according to their acute toxicity. In 2002, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was introduced, which in addition to acute toxicity also provides classification of chemicals according to their chronic health hazards and environmental hazards.

Book Description
To preserve the environment with the lowest possible cost to the social sector means that private costs should be aligned with social costs. Many governments in the Latin American and Caribbean Region are doing this now using market-based instruments (MBIs). This publication investigates the use of MBIs in the Latin America and the Caribbean (LAC) context. The investigation covers a sample of eleven countries in the region and a cross-section of environmental issues in an urban setting.
