Anthropogenic and natural sources of bromine. The major sources include sea spray, salt lakes, marshes, volcanos, anthropogenic sources. Sinks include exchange of brominated compounds with the stratospheric and troposphere.Bromine's chemistry is linked to other halogens such as chlorine and iodine amplify atmospheric cycling that contributes to troposphere and stratosphere ozone layer ...
Today, bromine is transported in large-capacity metal drums or lead-lined tanks that can hold hundreds of kilograms or even tonnes of bromine. The bromine industry is about one-hundredth the size of the chlorine industry. Laboratory production is unnecessary because bromine is commercially available and has a long shelf life. [61]
Where desired, free bromine may be obtained by thermal decomposition of ferrous bromide. [1] Before Dow entered the bromine business, brine was evaporated by heating with wood scraps and then crystallized sodium chloride was removed. An oxidizing agent was added, and bromine was formed in the solution. Then bromine was distilled.
Herbert Henry Dow (February 26, 1866 – October 15, 1930) was an American chemical industrialist who founded the American multinational conglomerate Dow Chemical.A graduate of the Case School of Applied Science in Cleveland, Ohio, he was a prolific inventor of chemical processes, compounds, and products, notably bromine extraction from sea water, and was a successful businessman.
All the world's bromine production is derived from brine. The majority is recovered from Dead Sea brine at plants in Israel and Jordan, where bromine is a byproduct of potash recovery. Plants in the United States (see: Bromine production in the United States), China, Turkmenistan, and Ukraine, recover bromine from subsurface brines. In India ...
Production expanded further in 1897, when Herbert Dow founded the Dow Chemical Company, and started producing bromine from the brines of the Michigan Basin, using an improved bromine extraction process that he invented, "air stripping." With his new process, Dow was able to undercut the bromine prices of German producers, who had dominated the ...

The major sources include sea spray, salt lakes, marshes, volcanos, anthropogenic sources, and the least input is the polar regions. Bromine's chemistry is linked to other halogens such as chlorine and iodine amplify atmospheric cycling that contributes to troposphere and stratosphere ozone layer destruction.
