The analysis stated that approximately 14 million people are impacted by the carcinogenic pollutant, also known as TCE. The compound is denser than water, in which it is practically insoluble. The most important use of trichloroethylene is the degreasing of metal parts in the automotive and metal industries. Its symptoms are similar to those of alcohol intoxication, beginning with headache, dizziness, and confusion and progressing with increasing exposure to unconsciousness. 2009. Health effects with positive findings in at least one study that evaluated exposure to TCE and/or PCE: Chonal atresia (nasal passages blocked with bone or tissue) (1, 2) Eye defects ; Low birth weight One of the main features about a VOC is that it can change from a liquid state to a vapor (or gaseous) state. In Canada, Studies have shown that simultaneous alcohol consumption and trichloroethylene inhalation increases the toxicity of trichloroethylene in humans. Some occupationally exposed individuals have developed rashes after coming into contact with concentrated TCE solutions. The chemical compound trichloroethylene is a halocarbon commonly used as an industrial solvent.It is a clear, colourless non-flammable liquid with a chloroform-like sweet smell. The current California Maximum Contaminant Level (MCL) is 0.005 This report reviews the literature on the impact of exposure to trichloroethylene (TCE) on human health. CAS No. Public water supplies must meet MCLs. Some studies of people exposed over long periods to high levels of trichloroethylene in drinking water or in workplace air have found evidence of increased cancer. What recommendations has the federal government made to protect human health?

Chiu WA, Jinot J, Scott CS, Makris SL et al. Health Effects of the Chemicals Find commonly asked questions and answers about chemicals found at Camp Lejeune and their human health effects. Therefore, the health problems seen in people who worked with TCE, PCE, benzene, and VC may not be seen in people who drank contaminated water. Institutions from Canada, Denmark, Finland, CNS effects; decreased appetite; gastrointestinal irritation; headaches; mucous membrane; skin irritation; Hepatotoxicity has been associated primarily with TCE inhalation and ingestion of very large amounts. Exposure can result in effects to the immune and reproductive systems, liver, kidneys, central nervous system, and may affect fetal development during pregnancy. Trichloroethylene effects on gene expression during cardiac development. TCE exposure may cause kidney cancer and increase the risk of lymphoma and liver cancer. This report reviews the literature on the impact of exposure to trichloroethylene (TCE) on human health. 888-232-6348 (TTY) Inhaling moderate amounts in the air may cause headaches, dizziness, poor coordination, difficulty concentrating, facial numbness, and lung irritation. (1,2) Chronic Effects (Noncancer): As with acute exposure, chronic exposure to trichloroethylene by inhalation also affects the human central nervous system. Liquid TCE evaporates quickly into the air. describe the physiological effects associated with TCE exposure. It is practically insoluble in water and evaporates quickly. Other effects seen in people exposed to high levels of trichloroethylene include evidence of nervous system effects related to hearing, seeing, and balance, changes in the rhythm of the heartbeat, liver damage, and evidence of kidney damage. Birth Defects Res A Clin Mol Teratol 67:488-495 14565619. Trichloroethylene has a long list of potentially hazardous health effects. 222 0 obj <>stream Studies indicate that 40 to 70 percent of TCE is absorbed by inhalation exposure, which is the most common TCE exposure route. The Minnesota Department of Health (MDH) has issued Health Based Values (HBVs) for Trichloroethylene (TCE) in drinking water. Are there medical tests to determine whether I have been exposed to trichloroethylene? The Virginia Department of Health (VDH) recommends installing a whole-house charcoal filtration device to remove trichloroethylene contamination from drinking water. Trichloroethylene (TCE) is a chemical that is categorized as a volatile organic compound (VOC). Human Health Effects … Health Effects of TCE . Some people who drink water containing trichloroethylene in excess of the MCL over many years could experience problems with their liver and may have an increased risk of getting cancer. Inhalation of more than 50 ppm (parts per million) trichloroethylene can produce acute effects on the body, including nausea and vomiting, eye and throat irritation, dizziness, headache, and liver, heart, or neurological damage. Trichloroethylene (TCE) and dichloroethylene (DCE) are high‐volume industrial chemicals frequently found as contaminants in public drinking water supplies. Effects resulting from acute, inhalation exposure of humans to tetrachloroethylene vapors include irritation of the upper respiratory tract and eyes, kidney dysfunction, and at lower concentrations, neurological effects, such as reversible mood and behavioral changes, impairment of coordination, dizziness, headache, sleepiness, and unconciousness. Inhalation can also cause lung damage as well as heart, nerve, kidney and liver damage, followed by death. In other words, if TCE is in drinking water it can be released into the air when a faucet is turned on. Brain cancer ( 26) Lung cancer ( 27) Liver cirrhosis ( 28) Workers are exposed to much higher levels of TCE, PCE, benzene, and VC than are people who drink contaminated water. Breathing TCE vapor, especially at high levels or over long periods of time, can cause negative health effects. It is a nonflammable colorless liquid with a sweet odor similar to ether or chloroform.

Toxicological Prior to the early 1970s, most trichloroethylene was produced in a two-step process from acetylene.First, acetylene was treated with chlorine using a ferric chloride catalyst at 90 °C to produce 1,1,2,2-tetrachloroethane according to the chemical equation. The Environmental Working Group, (EWG) a research non-profit agency, released an analysis of tests from public utilities nationwide. Trichloroethylene (TCE) and related solvents are found at approximately 40% of the hazardous waste sites on the US Environmental Protection Agency's National Priorities list (ATSDR, 1997).TCE frequently contaminates ground water, leading to human exposure through the municipal water distribution system. Overview Health effects Environmental effects Sources of emissions References Description Trichloroethylene is primarily used as a solvent to remove greases from metal parts. It is a nonflammable colorless liquid with a sweet odor similar to ether or chloroform. The general public may be exposed to TCE by drinking, breathing or bathing in contaminated water. Trichloroethylene was first prepared in 1864; its commercial manufacture, begun in Europe in 1908, is based on the reaction of 1,1,2,2-tetrachloroethane with dilute caustic alkali. If your well water has TCE contamination at levels greater than 1 ug/L you should treat the water to remove TCE. %%EOF 170 0 obj <> endobj These pieces of machinery or equipment would be cleaned with the use of TCE and some kind of cleaning cloth or simply dunked into the fluid.
