In higher doses, it can lead to tense breathing, complete muscle relaxation and paralysis of the chest muscles, which can often be fatal. [32] Sodium hypochlorite solution (chlorine bleach) mixed with common household liquids such as acetone, methyl ethyl ketone, ethanol, or isopropyl alcohol can produce some chloroform, in addition to other compounds such as chloroacetone or dichloroacetone. WebChloroform, or Trichloromethane, is an organic compound with formula C H Cl 3 and a common organic solvent.It is a colorless, strong-smelling, dense liquid produced on a large scale as a precursor to PTFE and refrigerants. The Scottish physician Sir James Simpson of the University of Edinburgh was the first to use it as an anesthetic in 1847. Breathing about 900 parts of chloroform in a million parts of air (900 ppm or 900,000 ppb) for a short time causes fatigue, dizziness, and headache. WebChloroform is labeled in the carcinogen class of drugs, making it illegal. } 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. However, most of the chloroform found in the environment is produced by humans.
