[16] The hepatotoxicity and nephrotoxicity of chloroform is thought to be due largely to phosgene. Based on animal studies, the Department of Health and Human Services (DHHS) has determined that chloroform may reasonably be anticipated to be a carcinogen (a substance that causes cancer). Chloroform is a transparent liquid having a slightly sweet taste and an ether-like odour. Chloroform. WebChloroform 67-66-3 Hazard Summary Chloroform may be released to the air as a result of its formation in the chlorination of drinking water, wastewater and swimming pools. In 1865, The Lancet, the medical journal, called upon any person, criminal or not, to prove that waving a chloroform drenched handkerchief was enough to knock someone out. You must also consider the other chemicals you're exposed to and your age, sex, diet, family traits, lifestyle, and state of health. }

[PDF], It is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. The average amount of chloroform that you might be exposed to on a typical day by breathing air in various places ranges from 2 to 5 micrograms per day (g/day) in rural areas, 6 to 200 g/day in cities, and 80 to 2,200 g/day in areas near major sources of the chemical. Surface water containing 394 ppb has also been found near a hazardous waste site; however, no more than 0.13 ppb has been found in soil at hazardous waste sites. The ratio for making chloroform needs to be 1 part acetone to 50 parts bleach. We do not know whether chloroform causes harmful reproductive effects or birth defects in people. Following chloroform-induced anesthesia, some patients suffered nausea, vomiting, hyperthermia, jaundice, and coma due to hepatic dysfunction.

Chloroform usually collects in body fat; however, its volatility ensures that it will eventually be removed once the exposure has been removed. Other sources include pulp and paper mills, hazardous waste sites, and sanitary landfills. It can harm the eyes, skin, liver, kidneys, and nervous system. [36], Chloroform is metabolized in the liver by the cytochrome P-450 enzymes, by oxidation to chloromethanol and by reduction to the dichloromethyl free radical. Workers may be harmed from exposure to chloroform. The EPA has determined that chloroform is a probable human carcinogen. It will only burn when it reaches very high temperatures. It is It is also part of wider class of substances known as volatile organic compounds. When a substance is released from a large area, such as an industrial plant, or from a container, such as a drum or bottle, it enters the environment. A) Chloroform may be mutagenic and induce DNA damage, DNA repair, and sister chromatid exchanges. chloroform (CHCl3), also called trichloromethane, nonflammable, clear, colourless liquid that is denser than water and has a pleasant etherlike odour.

We do not know whether liver and kidney cancer would develop in people after long-term exposure to chloroform in drinking water. Chlorine is added to most drinking water and many waste waters to destroy bacteria. Chloroform is a transparent liquid having a slightly sweet taste and an ether-like odour. 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. 1997. Chloroform, if inhaled in very small doses, can keep a person unconscious from 20 minutes to 2 hours or even more, depending on how concentrated the dose is. It was first prepared in 1831. [45] In the United States, chloroform began to replace ether as an anesthetic at the beginning of the 20th century; it was quickly abandoned in favor of ether upon discovery of its toxicity, however, especially its tendency to cause fatal cardiac arrhythmia analogous to what is now termed "sudden sniffer's death". Deuterochloroform is produced by the haloform reaction,[citation needed] the reaction of acetone (or ethanol) with sodium hypochlorite or calcium hypochlorite. The child's mother's boyfriend, Adolphus Earl Kimrey II, has been arrested and charged with her murder but has pleaded not guilty.

Chloroform is a trichloro derivative of methane first discovered in \ (1831\) by Liebig. [8] At 400500C, a free radical halogenation occurs, converting these precursors to progressively more chlorinated compounds: Chloroform undergoes further chlorination to yield carbon tetrachloride (CCl4): The output of this process is a mixture of the four chloromethanes: chloromethane, dichloromethane, trichloromethane (chloroform), and tetrachloromethane (carbon tetrachloride). Furthermore, EPA requires that spills of 10 pounds or more of chloroform into the environment be reported to the National Response Center. It is one of the four chloromethanes and a trihalomethane. The estimated amount of chloroform you probably are exposed to in drinking water ranges from 4 to 88 g/day. Most chloroform in the air eventually breaks down, but this process is slow.
