Summary: Fluorides, hydrogen fluoride, and fluorine are chemically related. Fluorine is a naturally-occurring, pale yellow-green gas with a sharp odor. It combines with metals to make fluorides such as sodium fluoride and calcium fluoride, both white solids. Sodium fluoride dissolves easily in water, but calcium fluoride does not. Fluorine also combines with hydrogen to make hydrogen fluoride, a colorless gas. Hydrogen fluoride dissolves in water to form hydrofluoric acid. Fluorine and hydrogen fluoride are used to make certain chemical compounds. Hydrofluoric acid is used for etching glass. Other fluoride compounds are used in making steel, chemicals, ceramics, lubricants, dyes, plastics, and pesticides. Fluorides are often added to drinking water supplies and to a variety of dental products, including toothpaste and mouth rinses, to prevent dental cavities.
Fact sheet that answers the most frequently asked questions about a contaminant and its health effects.
Summary about a hazardous substance taken from Chapter One of its respective ATSDR Toxicological Profile.
The Oak Ridge Reservation is a US Department of Energy (DOE) facility that was established in Oak Ridge, Tennessee in 1942 as part of the Manhattan Project, the federal government's World War II effort to build the atomic bomb. There are three major installations at the Oak Ridge site: the Y- 12 weapons plant; the X-10 complex, now known as the Oak Ridge National Laboratory; and the gaseous diffusion plant, K-25, now known as the East Tennessee Technology Park.
Publication intended to aid emergency department physicians and other emergency healthcare professionals who manage acute exposures resulting from chemical incidents.
Toxicological and Health Professionals
Succinctly characterizes the toxicologic and adverse health effects information for a hazardous substance.
Quick reference guide providing information such as chemical and physical properties, sources of exposure, routes of exposure, minimal risk levels, children's health, and health effects for a substance.
Prioritization of substances based on a combination of their frequency, toxicity, and potential for human exposure at National Priorities List (NPL) sites.
The MRL is an estimate of the daily human exposure to a hazardous substance that is likely to be without appreciable risk of adverse, non-cancer health effects over a specified duration of exposure. The information in this MRL serves as a screening tool to help public health professionals decide where to look more closely to evaluate possible risk of adverse health effects from human exposure.
Succintly characterizes the toxicologic and adverse health effects information for mixtures of hazardous substances.
