Bromoform is the main trihalomethane produced in beachfront salt water swimming pools with concentrations as high as 1.2 ppm (parts per million). Concentrations in freshwater pools are 1000 times lower. [ 9 ]
The EPA limits the total concentration of the four chief constituents (chloroform, bromoform, bromodichloromethane, and dibromochloromethane), referred to as total trihalomethanes (TTHM), to 80 parts per billion in treated water. [6] Traces of chloroform are produced in swimming pools. [7] [8] [9] [10]
Bromoform, produced by several algae, is a known toxin, though the small amounts present in edible algae do not appear to pose human harm. [12] Some of these organobromine compounds are employed in a form of interspecies "chemical warfare".
Like all macroalgae, Asparagopsis contains bromoform, a halogen compound which is known to inhibit methane production in ruminants. It has been shown to convert much of the enteric methane (a powerful greenhouse gas) to energy (and some carbon dioxide) for cattle during normal digestion. Because of its high bromoform content, Asparagopsis has ...

1,1,2,2-Tetrabromoethane, or simply tetrabromoethane (TBE), is a halogenated hydrocarbon, chemical formula C 2 H 2 Br 4.Although three bromine atoms may bind to one of the carbon atoms creating 1,1,1,2-tetrabromoethane this is not thermodynamically favorable, so in practice tetrabromoethane is equal to 1,1,2,2-tetrabromoethane, where each carbon atom binds two bromine atoms.
According to Bapton, sugar and salt technically never expire. But some of the ingredients added to salt, like iodine, can start to break down, so try to use it within 5 years. Sugar and salt can ...
The Sandmeyer reaction can also be used to convert aryl amines to phenols proceeding through the formation of an aryl diazonium salt. In the presence of copper catalyst, such as copper(I) oxide , and an excess of copper(II) nitrate , this reaction takes place readily at room temperature neutral water. [ 28 ]
