Quantitation and diversity analysis of ruminal methanogenic populations in response to the antimethanogenic compound bromochloromethane
Although challenges remain, the Montreal Protocol has been recognized as a global success, demonstrated by the massive elimination of production and consumption of CFCs (chlorofluorocarbons), halons, carbon tetrachloride, methyl chloroform, methyl bromide, and bromochloromethane
worldwide since it came into force in 1987.
May 31, 2013 /PRNewswire/ -- Albemarle Corporation(NYSE: ALB), a global developer, manufacturer and marketer of highly engineered specialty chemicals, announced today that it will increase global prices for dibromomethane (also referred to as DBM, methylene dibromide, or MDB) and bromochloromethane
(also referred to as BCM) by 25%.
