Clearing the Air


Book Description

America's air quality is better today than ever before in modern history and continues to steadily improve. How did this remarkable turnaround come about? Basing his conclusions on a painstaking compilation of long-term empirical data on air quality and emissions data extending from the pre- federalization era to the present (some dating back a century), Goklany challenges the orthodoxy that credits federal regulation for improving air quality. He shows that the air had been getting cleaner prior to—and probably would have continued to improve regardless of—federalization. States and localities, after all, have always been engaged in a race to improve the quality of life, which means different things at different stages of economic development. Goklany’s empirical data refute once and for all the race-to-the-bottom rationale for centralized federal regulation. Moreover, technological advances and consumer preferences continue to play important roles in improving air quality. Goklany accordingly offers a regulatory reform agenda that would improve upon the economic efficiency and environmental sensitivity of air quality regulation.




How Tobacco Smoke Causes Disease


Book Description

This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.




The Health Consequences of Involuntary Exposure to Tobacco Smoke


Book Description

This Surgeon General's report returns to the topic of the health effects of involuntary exposure to tobacco smoke. The last comprehensive review of this evidence by the Department of Health and Human Services (DHHS) was in the 1986 Surgeon General's report, The Health Consequences of Involuntary Smoking, published 20 years ago this year. This new report updates the evidence of the harmful effects of involuntary exposure to tobacco smoke. This large body of research findings is captured in an accompanying dynamic database that profiles key epidemiologic findings, and allows the evidence on health effects of exposure to tobacco smoke to be synthesized and updated (following the format of the 2004 report, The Health Consequences of Smoking). The database enables users to explore the data and studies supporting the conclusions in the report. The database is available on the Web site of the Centers for Disease Control and Prevention (CDC) at http://www.cdc.gov/tobacco.




Devastation and Renewal


Book Description

Every city has an environmental story, perhaps none so dramatic as Pittsburgh's. Founded in a river valley blessed with enormous resources-three strong waterways, abundant forests, rich seams of coal-the city experienced a century of exploitation and industrialization that degraded and obscured the natural environment to a horrific degree. Pittsburgh came to be known as "the Smoky City," or, as James Parton famously declared in 1866, "hell with the lid taken off."Then came the storied Renaissance in the years following World War II, when the city's public and private elites, abetted by technological advances, came together to improve the air and renew the built environment. Equally dramatic was the sweeping deindustrialization of Pittsburgh in the 1980s, when the collapse of the steel industry brought down the smokestacks, leaving vast tracks of brownfields and riverfront. Today Pittsburgh faces unprecedented opportunities to reverse the environmental degradation of its history. In Devastation and Renewal, scholars of the urban environment post questions that both complicate and enrich this story. Working from deep archival research, they ask not only what happened to Pittsburgh's environment, but why. What forces-economic, political, and cultural-were at work? In exploring the disturbing history of pollution in Pittsburgh, they consider not only the sooty skies, but also the poisoned rivers and creeks, the mined hills, and scarred land. Who profited and who paid for such "progress"? How did the environment Pittsburghers live in come to be, and how it can be managed for the future?In a provocative concluding essay, Samuel P. Hays explores Pittsburgh's "environmental culture," the attitudes and institutions that interpret a city's story and work to create change. Comparing Pittsburgh to other cities and regions, he exposes exaggerations of Pittsburgh's environmental achievement and challenges the community to make real progress for the future. A landmark contribution to the emerging field of urban environmental history, Devastation and Renewal will be important to all students of cities, of cultures, and of the natural world.
