This webpage is maintained by the Centers for Disease Control and Prevention (CDC). The webpage provides information and resources on Bromine. "Bromine is a naturally occurring element that is a liquid at room temperature. It has a brownish-red color with a bleach-like odor, and it dissolves in water. Bromine is found naturally in the earth's crust and in seawater in various chemical forms. Bromine can also be found as an alternative to chlorine in swimming pools. Products containing bromine are used in agriculture and sanitation and as fire retardants (chemicals that help prevent things from catching fire). Some bromine-containing compounds were historically used as sedatives (drugs that can make people calm or sleepy). However, these drugs are for the most part no longer found on the market in the United States."
