  • Countries the world over, especially in the developing world, are experiencing rapid urbanization. The share of the world’s population living in cities is reported to have grown from about 35 percent in 1970 to almost 50 percent in 2001, and this number is expected to increase to more than 60 percent by 2030 (UN-HABITAT 2001). One of the many consequences of the increased economic activity that accompanies urbanization—particularly increased vehicle use, electricity generation, and industrial production—is the deterioration of air quality (Molina 2004)....

  • In order to understand and manage our air quality resources, it is necessary to gain a fundamental understanding of the principles that govern our ability to do so. From a local perspective, it may be considered desirable to install huge fans in order to “blow the smog away,” but from a technological and scientific perspective it is not feasible. Likewise, from a regional or continental perspective, it is not acceptable to merely transfer air contaminants from one location to another one by dilution or “blowing it away.”...

  • In relation to studies and understanding of broad energy and pollution management issues, the U.S. National Academies have had an on-going program of cooperation with the Chinese Academies (Chinese Academy of Sciences and Chinese Academy of Engineering) for a number of years. Joint study activities date to the late 1990s and led to the publication in 2000 of Cooperation in the Energy Futures of China and the United States. This volume was the first examination of the broad energy questions facing both nations at the turn of the new millennium. ...

  • The global environment is changing rapidly, partly in response to economic globalization. These global changes are clearly evident at the local level, even in the quality of air that people breath. In some high income countries air quality has been improving, due to a combination of de-industrialization, improved technologies and environmental regulation. However, advances in the science of epidemiology suggest that even air that would until recently have been considered ‘clean’ may contain pollutants that are hazardous to people’s health.

  • Because time-series studies focus on a given geographic location over a number of years, factors that are often thought to influence the health of the population, such as percentage of smokers, income level, occupational exposure to pollutants, access to medical care and age distribution, do not need to be incorporated into the analysis as they are considered to remain relatively constant within the study area over time. Typically, the only other factors aside from pollution included in these models are weather variables and seasonal controls.

  • Unmeasured confounders are factors that influencemortality and vary with time in amanner that is similar to air pollution. These factors produce seasonal and long-termtrends inmortality that can confound the relationship between mortality and air pollution. Influenza and respira- tory infectionsmight reasonably be considered among themost important, usually unmeasured or not readily available confounders which produce seasonal patterns in mortality.

  • Critical loads are typically expressed as deposition loading rates of one or more pollutants in amount per area per year (e.g., kilo- grams per hectare per year (kg/ha/yr)). Critical loads are based on changes to specific biological or chemical indicators such as species composition of a given ecosystem (e.g., grassland) or biotic community (e.g., understory plants or tree-dwelling lichens) or acid neu- tralizing capacity (ANC) in soils, streams or lakes. Because different sensitive receptors (e.g.

  • As the demand for a clean, safe environment grows, so also grows the public demand for protection from the health hazards and environmental horrors of hazardous waste mismanagement. Entrepreneurs of industry and commerce provide daily evidence of the general awakening to the need for reduction or elimination of hazardous waste sources and better management of the wastes that are generated.

  • Many have endeavored to make our outdoor environment cleaner and safer. The learning process that occurred showed us the limitations of our planet and also the sustainability of our ecosystem if given a chance. As a community, we learned about the water, the soil, and the air. We learned about the underground river that flowed to the surface lake. We learned about air currents that transported airstreams around our globe. We discovered the reality of plate tectonics and the ever-changing hydrogeological system.

  • Outside the air regulatory setting, park, forest, and refuge managers may use data from air pollution related lichen studies to aid management decisions, conduct NEPA analyses, and provide information to the public about resource condition and impacts. To meet the requirements of the Wilderness Act, Organic Act, and National Wildlife System Improvement Act, federal land managers often subscribe to what is known as the “precautionary principle.
