Two of these plants extracted elemental bromine only for sale and did not produce compounds. In addi lion, other plants, not shown in -table 3, made compounds only from purchased bromine. CONSUMPTION AND USES The Bureau of Mines has not surveyed the consumers of bromine and bromine compounds for many years and therefore does not have 1972 data on the final disposition of these products. It was known, however, that over 74% of U.S. production in 1972 went to the manufacture of ethylene dibromide. Most of this production was used in gasoline additives, but the compound was also used in agriculture and as a solvent. In 1971 there was great pessimism over the future of ethylene dibromide because of the Clean Air Act of 1970, which required a 90% reduction in harmful emissions from automobile exhausts by the year 1975. This pessimism, however, was apparently not justified by actual conditions because, in 1972, the industry rebuilt depleted inventories and de veloped new markets for bromine compounds. The use of bromine in the manufacture of flame retardants was also believed to be on the increase. It was estimated that between 3% and 4% of total bromine production went into the manufacture of flame retardan-ts in 1972. Agricultural chemicals also increased, but the extent of the increase was not known. Methyl bromide was classed primarily as an agricultural chemical because of its extended use as a soil sterilant and insect fumigant. Many of the agricultural chemicals were proprietary, and their exact composition was not widely known. Elemental bromine was utilized as a disinfectant, algaecide, and as an oxidizing intermediate in the manufacture of other chemicals.
