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.
Trichloroethylene (TCE) is a halocarbon with the formula C 2 HCl 3, commonly used as an industrial metal degreasing solvent. It is a clear, colourless, non-flammable, volatile liquid with a chloroform-like pleasant mild smell [3] and sweet taste. [9] Its IUPAC name is trichloroethene. Trichloroethylene has been sold under a variety of trade names.
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]
The chemicals — trichloroethylene and perchloroethylene (PCE or perc) — can cause multiple kinds of cancers and damage to the kidney, liver and immune and nervous systems at high exposure ...

[9] In September 2019, CBC/Radio-Canada joined the Trusted News Initiative, intended to develop tools to assist news industry partners in "moving quickly and collectively to undermine disinformation before it can take hold."
This list focuses on the hazard linked to the agents. This means that while carcinogens are capable of causing cancer, it does not take their risk into account, which is the probability of causing a cancer, given the level of exposure to this carcinogen. [2] The list is up to date as of January 2024. [3]
