Ethylene Dibromide (EDB)

Also known as: Dibromoethane, Soilbrom, Dowfume, Bromofume, KopFume, Nephis
Chemical reference number (CAS): 106-93-4

The U.S. Environmental Protection Agency (EPA) considers EDB an extremely hazardous chemical. In 1948, EPA registered the chemical for use as an insect killer. EDB is a clear heavy liquid, with a sweet fragrance. EDB was used to control insects in stored products, on fruits and vegetables, in flour mills, and in soil. EDB was also used as an ingredient in gasoline. In 1984, EPA stopped all agricultural uses of EDB because exposure was found to make male workers sterile. EDB is very poisonous and is shown to cause cancer and reproductive problems.

Most EDB in the environment results from its use in gasoline and from improper waste disposal.
