Bromoform was discovered in 1832 by Löwig who distilled a mixture of bromal and potassium hydroxide, as analogous to preparation of chloroform from chloral. [5]Bromoform can be prepared by the haloform reaction using acetone and sodium hypobromite, by the electrolysis of potassium bromide in ethanol, or by treating chloroform with aluminium bromide.
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]

The analysis, a review of 30 scientific studies involving over 90,000 participants, found elevated cancer risks with THM levels as low as 40 parts per billion (ppb).
Salt water chlorination is a process that uses dissolved salt (1000–4000 ppm or 1–4 g/L) for the chlorination of swimming pools and hot tubs.The chlorine generator (also known as salt cell, salt generator, salt chlorinator, or SWG) uses electrolysis in the presence of dissolved salt to produce chlorine gas or its dissolved forms, hypochlorous acid and sodium hypochlorite, which are already ...
Dynamic viscosity is a material property which describes the resistance of a fluid to shearing flows. It corresponds roughly to the intuitive notion of a fluid's 'thickness'.
In late 2024, Bovaer, a nitrate-based feed additive that doesn’t contain bromoform, was at the center of a social media storm in the UK after Arla, one of the largest dairy companies in the ...
According to the CDC, as of 2020, levels that it is normal to be exposed to in drinking water are lower than levels known to cause health problems. [1] A small number of studies have examined the effects of low levels of bromodichloromethane on people, but most were also exposed to other chemicals, so it may not be the only cause of reported health problems.
