WebChloroform (CHCl 3) is a colorless liquid that quickly evaporates into gas. Its golden age, however, was short-lived, as it was gradually replaced by ether that was much safer than chloroform, and had virtually no side effects. Chloroform usually collects in body fat; however, its volatility ensures that it will eventually be removed once the exposure has been removed. [54], Use of chloroform as an incapacitating agent has become widely recognized, bordering on clichd, due to the popularity of crime fiction authors having criminals use chloroform-soaked rags to render victims unconscious.

The Environmental Protection Agency (EPA) identifies the most serious hazardous waste sites in the nation. [citation needed], Historically, chloroform exposure may well have been higher due to its common use as an anaesthetic, as an ingredient in cough syrups, and as a constituent of tobacco smoke where DDT had previously been used as a fumigant. It is also a precursor to various refrigerants. [65], Chloroform is suspected of causing cancer (i.e., possibly carcinogenic, IARC Group 2B) as per the International Agency for Research on Cancer (IARC) Monographs. Although we can measure the amount of chloroform in the air that you breathe out, and in blood, urine, and body tissues, we have no reliable test to determine how much chloroform you have been exposed to or whether you will experience any harmful health effects.

Drinking water derived from well water near a hazardous waste site contained 1,900 ppb, and groundwater taken near a hazardous waste site also contained 1,900 ppb. It later captured public notice in 1853 It serves as an intermediate in the production of dyes and pesticides like chloropicrin, and is used as a fumigant of stored-grain crops. B) Chloroform did not induce unscheduled DNA synthesis in vitro or in vivo in mice (Larson et al, 1994). It is soluble in water. A shorter version, the ToxFAQs, is also available.

Formerly used during surgery as an inhaled anaesthetic, the main application of chloroform today is in agriculture, where it is used as a solvent, and also particularly in the manufacture of the refrigerant freon. It is one in a series of Public Health Statements about hazardous substances and their health effects. [58], It is well absorbed, metabolized, and eliminated rapidly by mammals after oral, inhalation, or dermal exposure. Scientific discovery can be unexpected and full of chance surprises. In modern times, however, it is manufactured industrially by combining methane with chlorine.Small amounts of the chemical are produced naturally [citation needed], The anaesthetic qualities of chloroform were first described in 1842 in a thesis by Robert Mortimer Glover, which won the Gold Medal of the Harveian Society for that year. National Institutes of Health. [citation needed], On 4 November 1847, Simpson first discovered the anaesthetic qualities of chloroform on humans.
