Community Toxicity Testing


Book Description

Although community level toxicity testing is now being used for practical purposes, it is not the intent of this book to espouse the use of community level testing in all situations or to replace single-species tests that are the best source of information on growth, reproductive success, behavior, and a variety of other end points. On the other hand, since field validation of laboratory predictions is becoming increasingly important and since community level testing offers the possibility of validation by using more comparable or identical end points in complex natural systems, which is not possible for single-species tests, it is now worthy of attention by ASTM members.




Toxic Communities


Book Description

From St. Louis to New Orleans, from Baltimore to Oklahoma City, there are poor and minority neighborhoods so beset by pollution that just living in them can be hazardous to your health. Due to entrenched segregation, zoning ordinances that privilege wealthier communities, or because businesses have found the OCypaths of least resistance, OCO there are many hazardous waste and toxic facilities in these communities, leading residents to experience health and wellness problems on top of the race and class discrimination most already experience. Taking stock of the recent environmental justice scholarship, a Toxic Communities aexamines the connections among residential segregation, zoning, and exposure to environmental hazards. Renowned environmental sociologist Dorceta Taylor focuses on the locations of hazardous facilities in low-income and minority communities and shows how they have been dumped on, contaminated and exposed. Drawing on an array of historical and contemporary case studies from across the country, Taylor explores controversies over racially-motivated decisions in zoning laws, eminent domain, government regulation (or lack thereof), and urban renewal. She provides a comprehensive overview of the debate over whether or not there is a link between environmental transgressions and discrimination, drawing a clear picture of the state of the environmental justice field today and where it is going. In doing so, she introduces new concepts and theories for understanding environmental racism that will be essential for environmental justice scholars. A fascinating landmark study, a Toxic Communities agreatly contributes to the study of race, the environment, and space in the contemporary United States."




Toxicity Testing in the 21st Century


Book Description

Advances in molecular biology and toxicology are paving the way for major improvements in the evaluation of the hazards posed by the large number of chemicals found at low levels in the environment. The National Research Council was asked by the U.S. Environmental Protection Agency to review the state of the science and create a far-reaching vision for the future of toxicity testing. The book finds that developing, improving, and validating new laboratory tools based on recent scientific advances could significantly improve our ability to understand the hazards and risks posed by chemicals. This new knowledge would lead to much more informed environmental regulations and dramatically reduce the need for animal testing because the new tests would be based on human cells and cell components. Substantial scientific efforts and resources will be required to leverage these new technologies to realize the vision, but the result will be a more efficient, informative and less costly system for assessing the hazards posed by industrial chemicals and pesticides.




Ecological Toxicity Testing


Book Description

Ecological Toxicity Testing provides a critical comparison of toxicity tests at different levels of biological organization from cells to landscapes. While ecological toxicity tests can be designed at any of the many levels of complexity and on spatial scales ranging from square millimeters to square kilometers, the uses to which this information can be put often differs with scale. In the past decade, tests at all levels have been refined and subjected to critical evaluations of their predictive accuracy. This text/reference includes evaluations of toxicity test systems at various scales and complexities by expert practitioners. It also offers broader analyses of the effects of scale on endpoint selection, test design and analyses, and chemical sensitivity.

Toxicologic Assessment of the Army's Zinc Cadmium Sulfide Dispersion Tests


Book Description

During the 1950s and 1960s, the U.S. Army conducted atmospheric dispersion tests in many American cities using fluorescent particles of zinc cadmium sulfide (ZnCdS) to develop and verify meteorological models to estimate the dispersal of aerosols. Upon learning of the tests, many citizens and some public health officials in the affected cities raised concerns about the health consequences of the tests. This book assesses the public health effects of the Army's tests, including the toxicity of ZnCdS, the toxicity of surrogate cadmium compounds, the environmental fate of ZnCdS, the extent of public exposures from the dispersion tests, and the risks of such exposures.
