The regulation of potentially hazardous substances has become a controversial issue. This volume evaluates past efforts to develop and use risk assessment guidelines, reviews the experience of regulatory agencies with different administrative arrangements for risk assessment, and evaluates various proposals to modify procedures. The book's conclusions and recommendations can be applied across the entire field of environmental health.

Even though women have made substantial progress in a number of formerly male occupations, sex segregation in the workplace remains a fact of life. This volume probes pertinent questions: Why has the overall degree of sex segregation remained stable in this century? What informal barriers keep it in place? How do socialization and educational practices affect career choices and hiring patterns? How do family responsibilities affect women's work attitudes? And how effective is legislation in lessening the gap between the sexes? Amply supplemented with tables, figures, and insightful...

From the interior of the Sun, to the upper atmosphere and near-space environment of Earth, and outward to a region far beyond Pluto where the Sun's influence wanes, advances during the past decade in space physics and solar physics--the disciplines NASA refers to as heliophysics--have yielded spectacular insights into the phenomena that affect our home in space.
Solar and Space Physics, from the National Research Council's (NRC's) Committee for a Decadal Strategy in Solar and Space Physics, is the second NRC decadal survey in heliophysics. Building on the research...

The AIDS virus is spread by human behaviors enacted in a variety of social situations. In order to prevent further infection, we need to know more about these behaviors. This volume explores what is known about the number of people infected, risk-associated behaviors, facilitation of behavioral change, and barriers to more effective prevention efforts.

Mathematics is the key to opportunity. No longer only the language of science, mathematics is now essential to business, finance, health, and defense. Yet because of the lack of mathematical literacy, many students are not prepared for tomorrow's jobs. Everybody Counts suggests solutions. Written for everyone concerned about our children's education, this book discusses why students in this country do not perform well in mathematics and outlines a comprehensive plan for revitalizing mathematics education in America, from kindergarten through college. single copy, $8.95; 2-9...

More and more farmers are adopting a diverse range of alternative practices designed to reduce dependence on synthetic chemical pesticides, fertilizers, and antibiotics; cut costs; increase profits; and reduce the adverse environmental consequences of agricultural production. Alternative Agriculture describes the increased use of these new practices and other changes in agriculture since World War II, and examines the role of federal policy in encouraging this evolution, as well as factors that are causing farmers to look for profitable, environmentally safe alternatives. Eleven...

Since its introduction in 1943 Recommended Dietary Allowances has become the accepted source of nutrient allowances for healthy people. These Recommended Dietary Allowances (RDAs) are used throughout the food and health fields. Additionally, RDAs serve as the basis for the U.S. Recommended Daily Allowances, the Food and Drug Administration's standards for nutrition labeling of foods. The 10th Edition includes research results and expert interpretations from years of progress in nutrition research since the previous edition and provides not only RDAs but also "Estimated Safe...

Studying animals in the environment may be a realistic and highly beneficial approach to identifying unknown chemical contaminants before they cause human harm. Animals as Sentinels of Environmental Health Hazards presents an overview of animal-monitoring programs, including detailed case studies of how animal health problems--such as the effects of DDT on wild bird populations--have led researchers to the sources of human health hazards. The authors examine the components and characteristics required for an effective animal-monitoring program, and they evaluate numerous existing...

Exciting new observational and theoretical advances lead today's solar physicists to challenge many of the predictions of even recent models. This volume summarizes the major questions at the forefront of solar physics theory and observations, and proposes priority recommendations to explore these questions. The study also addresses serious institutional issues that have beset solar physics including the role of the universities in the national solar observations, structural barriers to careers in solar physics, and the leadership role of the federal funding agencies for ground-based solar...
