The chloroform molecule can be viewed as a methane molecule with three hydrogen atoms replaced with three chlorine atoms, leaving a single hydrogen atom. The name "chloroform" is a portmanteau of terchloride (tertiary chloride, a trichloride) and formyle, an obsolete name for the methylylidene radical (CH) derived from formic acid. [citation ...
Concentrations of trihalomethanes (mainly chloroform) of up to 0.43 ppm have been measured. [5] In addition, trichloramine has been detected in the air above swimming pools, [6] and it is suspected in the increased asthma observed in elite swimmers. Trichloramine is formed by the reaction of urea (from urine and sweat) with chlorine and gives ...
One study found that n-nonane and formaldehyde were the main drivers of eye and upper respiratory tract irritation while cancer risks were driven by chloroform and formaldehyde. [81] Some solvent-based products have also been shown to cause damage to the kidneys and reproductive organs. [ 85 ]

Organochlorides such as trichloroethylene, tetrachloroethylene, dichloromethane and chloroform are commonly used as solvents and are referred to as "chlorinated solvents". [ citation needed ] Physical and chemical properties
Only chloroform has significant applications of the haloforms. In the predominant application, chloroform is required for the production of tetrafluoroethylene (TFE), precursor to teflon . [ 1 ] Chloroform is fluorinated by reaction with hydrogen fluoride to produce chlorodifluoromethane (R-22).
A recent study in the British Medical Journal highlights a link between ultra-processed diets and increased calorie intake, weight gain, and elevated risk of cardiovascular diseases. Participants ...
Hang gliding is actually one of the most dangerous in-air sports possible. According to HSE, a U.K.-based watchdog group, the risk of death in a hang-gliding accident is 1 out of every 116,000 ...
