Summary: Sulfur mustard (HD) is a thick liquid at ambient temperature, but becomes a solid at 58 °F. It is heavier than water as a liquid and heavier than air as a vapor. It does not occur naturally in the environment It is often called mustard gas, but sulfur mustard is not likely to change into a gas immediately if it is released at ordinary temperatures. As a pure liquid, it is colorless and odorless, but when mixed with other chemicals, it looks brown and has a garlic-like smell. Sulfur mustard has been used in chemical warfare and was made in large amounts during World Wars I and II. It was reportedly used in the Iran-Iraq war in 1980-1988. It is not presently used in the United States, except for research purposes, and the U.S. Department of Defense must destroy all remaining stocks of sulfur mustard by 2004.
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.
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.
