This toxicological profile succinctly characterizes the toxicologic and adverse health effects information for fluorides, hydrogen fluoride, and fluorine. Fluorides are often added to drinking water supplies and a variety of dental compounds. Some fluoride compounds are also used in the production of glass and enamel and in the steel industry. Fluorine gas is used primarily to make chemical compounds used in separating isotopes of uranium for use in nuclear reactors and nuclear weapons. Hydrogen fluoride is used in the manufacture of fluorocarbons, which are used as refrigerants, solvents, and aerosols. This profile includes: (A) The examination, summary, and interpretation of available toxicologic information and epidemiologic evaluations on fluorides, hydrogen fluoride, and fluorine to ascertain the levels of significant human exposure for the substance and the associated acute, subacute, and chronic health effects; (B) A determination of whether adequate information on the health effects of fluorides, hydrogen fluoride, and fluorine is available or in the process of development to determine levels of exposure that present a significant risk to human health of acute, subacute, and chronic health effects; and (C) Where appropriate, identification of toxicologic testing needed to identify the types or levels of exposure that may present significant risk of adverse health effects in humans. Tables and figures. This is a print on demand edition of a hard to find publication.

Provides info. about fluorine, hydrogen fluoride, & fluorides, & the human health effects of exposure. These chemicals have been found in many sites identified by the EPA for long-term Federal cleanup activities. Includes a Public Health Statement which explains toxicologic properties of fluorine, hydrogen fluoride, & fluorides in a nontechnical, Q&A format, & a review of the general health effects observed following exposure; a description of health effects; how the chemical can affect children; & info. on their chemical & physical properties, production, use & disposal, potential for human exposure, analytical methods, & regulations & advisories.

This book helps readers understand the fundamental principles and phenomena that control the transfer of trace elements. It describes the occurrence and behavior of trace elements in rocks, soil, water, air, and plants, and also discusses the anthropogenic impact to the environment. In addition, the book covers the presence of trace elements in feeds, as either contaminants or as nutritional or zootechnical additives, and their transfer across the food chain to humans. All trace elements are covered-from aluminum to zirconium-as well as rare-earth elements (actinides and lanthanides).

Tropical forests have seen a tremendous growth in logging, mining, and oil and gas development over the past decades. These industries and their infrastructure, including roads and power lines, have a tremendous impact on the environment and often conflict with the growing concern for conservation, particularly the conservation of tropical biodiversity. However, development in the tropics is extremely important economically, both for developing and industrialized nations, and Footprints in the Jungle is an invaluable reference in this important and highly politicized debate. This volume looks at new approaches that lessen the impact of development. It collects numerous case studies by project managers, advocates, and researchers from major international companies, development agencies, universities, and non-governmental organizations. It also examines the environmental and social impact of resource development, proposes a rigorous "best practices" approach, and analyzes a number of challenging technical, environmental, social, and legal issues.

Arsenic. Mercury. Pesticides. Dioxin. Toxic gases. Your typical hazardous waste dump, right? Wrong. These materials can be found in the home. Every day, people work, live, and play amid potentially harmful toxins-things they might not even know are there. They are exposed to these toxic substances in their homes, neighborhoods, schools, workplaces, foods, and consumer products. Now, two toxics experts with decades of experience in public health have created a book that separates the risks from the myths of everyday toxins. Comprehensive and easy-to-use, this guide provides scenarios and real-life examples-including important warning signs-that show how to identify problems and what to do about them. With Q&A segments, charts to help assess risk, and a special homebuyer's guide, What's Toxic, What's Not is a book no home should be without.
