It is a dense liquid with tetrahedral molecular geometry with C3 symmetry. Toxicological profile for chloroform. Chloroform can also numb or render people unconscious in small doses. [46] One possible mechanism of action for chloroform is that it increases movement of potassium ions through certain types of potassium channels in nerve cells. When ingested, chloroform is converted into a chemical called phosgene. 11002), and is subject to strict reporting requirements by facilities that produce, store, or use it in significant quantities. Chloroform was one of the first inhaled anesthetics to be used during surgery, but it is not used for anesthesia today. Some regulations and recommendations for chloroform include the following: The EPA sets rules for the amount of chloroform allowed in water. For good reason, chloroform is no longer used as an anesthetic; it is a difficult task to determine the right dose that would render a person unconscious without affecting other vital nerve functions.

Joseph Harris was charged in 1894 with using chloroform to rob people. [16], Chloroform has induced liver tumors in mice and kidney tumors in mice and rats. The laboratory experiments proving the dangers of chloroform were largely ignored. WebChloroform is labeled in the carcinogen class of drugs, making it illegal. Chloroform evaporates very quickly when exposed to air. Other metabolites of chloroform include hydrochloric acid and digluathionyl dithiocarbonate, with carbon dioxide as the predominant end product of metabolism. For the most current information, check with the federal agency or organization that provides it. Chloroform is used as a heat transfer medium in fire extinguishers, where it lowers the temperature of carbon tetrachloride. 1997. 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.

The Health Hazard Evaluation Program (HHE) conducts onsite investigations of possible worker exposure to chemicals. Chloroform usually collects in body fat; however, its volatility ensures that it will eventually be removed once the exposure has been removed. In chemical jargon, chloroform is liquid trichloromethane and is produced on an industrial scale by heating a mixture of chlorine and either chloromethane or methane. Chloroform. chloroform (CHCl3), also called trichloromethane, nonflammable, clear, colourless liquid that is denser than water and has a pleasant etherlike odour.
