| hazards summary | 1,2-Dibromoethane is a manufactured chemical. It also occurs naturally in small amounts in the ocean where it is formed, probably by algae and kelp. It is a colorless liquid with a mild, sweet odor. Other names for 1,2-dibromoethane are ethylene dibromide, EDB, and glycol bromide. Trade names include Bromofume and Dowfume. 1,2-Dibromoethane has been used as a pesticide in soil, and on citrus, vegetable, and grain crops. Most of these uses have been stopped by the Environmental Protection Agency (EPA) since 1984. Another major use was as an additive in leaded gasoline. however, since leaded gasoline is now banned, it is no longer used for this purpose. Uses today include treatment of logs for termites and beetles, control of moths in beehives, and as a preparation for dyes and waxes.Ethylene dibromide is a nonflammable colorless liquid with a sweet chloroform-like odor at room temperature above 50ºF (10ºC). It is slightly soluble in water and soluble in most organic solvents. It is heavier than water. When heated to decomposition, it may release gases and vapors such as hydrogen bromide, bromine, and carbon monoxide. Ethylene dibromide should be stored in a dry place at ambient temperature.Exposure to ethylene dibromide primarily occurs from its past use as an additive to leaded gasoline and as a fumigant. Ethylene dibromide is extremely toxic to humans. The chronic (long-term) effects of exposure to ethylene dibromide have not been well documented in humans. Animal studies indicate that chronic exposure to ethylene dibromide may result in toxic effects to the liver, kidney, and the testis, irrespective of the route of exposure. Limited data on men occupationally exposed to ethylene dibromide indicate that long-term exposure to ethylene dibromide can impair reproduction by damaging sperm cells in the testicles. Several animal studies indicate that long-term exposure to ethylene dibromideincreases the incidences of a variety of tumors in rats and mice in both sexes by all routes of exposure. EPA has classified ethylene dibromide as a Group B2, probable human carcinogen.In acute exposure studies in animals, ethylene dibromide is more toxic than a comparable dose of ethylene dichloride or carbon tetrachloride. It causes narcosis, respiratory irritation, kidney damage, and liver injury. Strong positive data that ethylene dibromide can cause testicular damage in humans. |
