Trichloroethylene Latest News

Long-term exposure to the industrial solvent trichloroethylene (TCE) outdoors may be linked to an increased risk of Parkinson’s disease, according to a recent study.

About Trichloroethylene

• It is a volatile, colorless liquid organic chemical. 
• TCE does not occur naturally and is created by chemical synthesis.

Trichloroethylene Applications

• It is used primarily to make refrigerants and other hydrofluorocarbons and as a degreasing solvent for metal equipment. 
• TCE is also used in some household products, such as cleaning wipes, aerosol cleaning products, tool cleaners, paint removers, spray adhesives, and carpet cleaners and spot removers. 
• Commercial dry cleaners also use trichloroethylene as a spot remover.

How are People Exposed to Trichloroethylene?

• TCE may be found in the air, water, and soil at places where it is produced or used. 
• It breaks down slowly and remains in the environment for a long time. 
• It readily passes through soil and can accumulate in groundwater.
• People in the general population can be exposed to TCE by inhaling it in indoor and outdoor air, drinking contaminated water, or eating foods that have been washed or processed with contaminated water.

Impact of Trichloroethylene on Human Health

• People with prolonged or repeated exposure to TCE could experience liver problems and may have an increased risk of developing liver or kidney cancer.
• TCE also has genotoxic and immunotoxic potential, and some studies indicate that it may be a teratogen.
• There is also increasing evidence supporting the association between TCE exposure and non-Hodgkin lymphoma, and several reproductive and developmental toxicity endpoints, including infertility in males and females, impaired fetal growth, and cardiac teratogenesis.
