Trichloroethylene is a good analgesic at 0.35 to 0.5% concentrations. [16] Trichloroethylene was used in the treatment of trigeminal neuralgia beginning in 1916. [17] Pioneered by Imperial Chemical Industries in Britain, under the trade name "Trilene" (from trichloroethylene) , its development was hailed as an anesthetic revolution. It was ...
Trichloroethylene (TCE) is more aggressive than PCE but is very rarely used today. With superior degreasing properties, it was often used for industrial workwear/overalls cleaning in the past. It is chemically related to tetrachloroethylene. TCE is classified as carcinogenic to humans by the United States Environmental Protection Agency. [12]
Between 1975 and 1985, the water supply of Marine Corps Base Camp Lejeune was contaminated with trichloroethylene and other volatile organic compounds. [10]In 1986, and later again in 2009, 2 plumes containing trichloroethylene was found on Long Island, New York due to Northrop Grumman's Bethpage factories that worked in conjunction with the United States Navy during the 1930s and 1940s.
Some haloalkanes are still widely used for industrial cleaning, such as methylene chloride (dichloromethane), and as refrigerants, such as R-134a (1,1,1,2-tetrafluoroethane). Haloalkenes have also been used as solvents, including perchloroethylene (Perc, tetrachloroethene), widespread in dry cleaning, and trichloroethylene (TCE, 1,1,2 ...
The U.S. EPA is in the process of evaluating the carcinogenic and non-carcinogenic human health risks from exposure to TCE. [2] Certain uses of TCE were banned in 1977 in the United States. However, TCE was still used in household products such as spot removers and typewriter correction fluid well into the 1990s. [3]
It poisoned the groundwater with high levels of dichloroethene, trichloroethylene, vinyl chloride and benzene, a Navy report released in 2000 said.The colorless chemicals can cause several ...
It's probably an overstatement that "[t]he long-term effects of trichloroethylene on human beings are unknown". The health effects of TCE are better understood that most chemicals, and while there's uncertainty concerning the significance of adverse effects at low levels of exposure, that a different point compared to the one stated in the article.
Every so often we hear horrifying stories of modern day cannibalism -- but there are still tribes where eating human flesh is part of the culture. Places where modern day cannibalism still exists ...
