    Hazard Summary-Created in April 1992; Revised in January 2000

    Most of the trichloroethylene used in the United States is released into the atmosphere from industrial degreasing operations. Acute (short-term) and chronic (long-term) inhalation exposure to trichloroethylene can affect the human central nervous system (CNS), with symptoms such as dizziness, headaches, confusion, euphoria, facial numbness, and weakness. Liver, kidney, immunological, endocrine, and developmental effects have also been reported in humans. A recent analysis of available epidemiological studies reports trichloroethylene exposure to be associated with several types of cancers in humans, especially kidney, liver, cervix, and lymphatic system.Animal studies have reported increases in lung, liver, kidney, and testicular tumors and lymphoma. The Agency is currently reassessing the cancer classification of trichloroethylene.

    Please Note: The main source of information for this fact sheet is the Agency for Toxic Substances and Disease Registry's (ATSDR's) Toxicological Profile for Trichloroethylene. Another secondary source used is EPA's Health Assessment Document for Trichloroethylene.


    • The main use of trichloroethylene is in the vapor degreasing of metal parts. (1)
    • Trichloroethylene is also used as an extraction solvent for greases, oils, fats, waxes, and tars, a chemical intermediate in the production of other chemicals, and as a refrigerant. (1)
    • Trichloroethylene is used in consumer products such as typewriter correction fluids, paint removers/strippers, adhesives, spot removers, and rug-cleaning fluids. (1)
    • Trichloroethylene was used in the past as a general anesthetic. (1)

    Sources and Potential Exposure

    • Trichloroethylene has been detected in ambient air at levels less than 1 part per billion (ppb). Ambient air measurement data from the Aerometric Information Retrieval System (which has 1,200 measurements from 25 states from 1985-1995) give a range of ambient air values from 0.01 to 3.9 micrograms per cubic meter (g/m3). (1,13)
    • Because of its moderate water solubility, trichloroethylene in soil has the potential to migrate into groundwater. The relatively frequent detection of trichloroethylene in groundwater confirms its mobility in soils. (13)
    • Drinking water supplies relying on contaminated groundwater sources may contain trichloroethylene. ATSDR reports that trichloroethylene is the most frequently reported organic contaminant in groundwater. It estimates betwe
