Utilisation. Le brome est employé à la fabrication de bromures métalliques, comme le bromure d'argent, utilisé en photographie, et le bromure de potassium, sédatif du système nerveux. Il sert aussi à l'obtention de dérivés organiques bromés, employés comme produits thérapeutiques, substances lacrymogènes, matières colorantes. Le brome est également utilisé sous forme de dibromoéthane dans la préparation du plomb tétraéthyle, qui sert comme antidétonant dans les carburants. 3, record 1, French, - brome

Le brome est un élément fondamental des halons (bromofluorocarbures) qui sont d'efficaces agents extincteurs d'incendie. Malheureusement, les halons les plus utiles (1211, 1301 et 2402) possèdent un très grand pouvoir de destruction de l'ozone. Le Halon 1301 est aussi un gaz à effet de serre mineur. 4, record 1, French, - brome

The use of fumigants such as methyl bromide and epoxides(i. e., ethylene and propylene oxides) is important in the treatment of large volumes of foodstuffs to destroy insects. In addition, ethylene oxide-carbon dioxide processes have been developed for greatly reducing the bacterial populations of heat sensitive, highly flavored substances; spices are given such treatments to reduce to tolerable amounts the incidence of thermophilic contaminants. 4, record 2, English, - ethylene%20oxide
