Tetrachloroethylene is regarded as a toxic substance, a human health hazard, and an environmental hazard. [ 5 ] [ 7 ] In 2020, the United States Environmental Protection Agency stated that "tetrachloroethylene exposure may harm the nervous system, liver, kidneys, and reproductive system, and may be harmful to unborn children", and reported that ...
1,1,2,2-tetrachloroethane was used in large amounts to produce other chemicals like trichloroethylene, tetrachloroethylene, and 1,2-dichloroethylene. [6] Because of its possible carcinogen effects on humans, the production of 1,1,2,2-tetrachloroethane has decreased significantly and is no longer widely used as an end-product. [7]
The earliest record of trichloroethylene synthesis dates back to 1836. It was obtained from the action of potassium hydroxide on 1,1,2,2-tetrachloroethane and 1,1,1,2-tetrachloroethane by Auguste Laurent and notated as C 4 HCl 3 (then the atomic weight of carbon was thought to be the half of it really was).
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.
The natural organochloride epibatidine, an alkaloid isolated from tree frogs, has potent analgesic effects and has stimulated research into new pain medication. However, because of its unacceptable therapeutic index , it is no longer a subject of research for potential therapeutic uses. [ 9 ]
Toxic abortion is observed in both humans and in animals such as cows, [11] [12] [13] hares, [14] and horses. [15] The source notes that animal ingestion of "low quality forage having some toxicity" harms livestock health, especially with cattle and horses, leading to numerous cases of "toxic abortion, gastro-enteritis and abortion with ...
ATSDR is an agency within the US Department of Health and Human Services concerned with the effects of hazardous substances on human health. ATSDR is charged with assessing the presence and nature of health hazards at specific Superfund sites, as well as helping prevent or reduce further exposure and the illnesses that can result from such exposures.
