Quantitation and diversity analysis of ruminal methanogenic populations in response to the antimethanogenic compound bromochloromethane
The protocol covers over 200 individual substances with a high ozone-depleting potential, including chlorofluorocarbons (CFCs), halons, carbon tetrachloride (CTC), 1,1,1-Trichloroethane (TCA), hydrochlorofluorocarbons (HCFCs), hydrobromofluorocarbons (HBFCs), bromochloromethane
(BCM) and methyl bromide (MB), all of which are referred to as 'controlled substances'.
several halogenated CH4 analogues such as chloroform, bromochloromethane
(McAllister and New bold (2008) and statins (Miller and Wolin, 2001) have been exploited in reducing the production of CH4.
Albemarle Corporation (NYSE: ALB), a global developer, manufacturer and marketer of highly engineered specialty chemicals, is increasing the global price for dibromomethane and bromochloromethane
effective immediately, or as contracts allow.
The most common controlled substances include: Halo carbons, notably chlorofluorocarbons (CFCs) and Halons; Carbon tetrachloride; Methyl chloroform (1,1,1 trichloroethane); Hydrobromofluorocarbons (HBFCs); Hydrochlorofluorocarbons (HCFCs); Methyl bromide (CH3Br); and Bromochloromethane
(BCM), a new ozone-depleting substance that some companies sought to introduce into the market in 1998, which has been targeted by the 1999 Beijing Amendment for immediate phase-out to prevent its use.
In the framework of Regulation 2037/2000 EC on substances that deplete the ozone layer, and in compliance with commitments made under the Montreal Protocol on these same products and the protection of the ozone layer, the EU has scheduled the gradual abandonment of the production and use of chlorofluorocarbons, other fully halogenated chlorofluorocarbons, halons, carbon tetrachloride, 1,1,1-trichloroethane, hydrobromofluorocarbons and 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.
It concerns the following: chlorofluorocarbons (CFCs), methyl bromide, hydrochlorofluorocarbons (HFCs), hydrobromofluorocarbons (HBCs) and bromochloromethane
, intended for various applications or used as synthesis intermediaries or process agents.
Four of the 10 possible THMs regulated as total THMs are trichloromethane (chloroform), tribromomethane (bromoform), bromodichloromethane and bromochloromethane
The substances include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, 1,1,1 trichloroethane, carbon tetrachloride and bromochloromethane
