Trikloretylen

Trichloroethylene (TCE), also known as trichlorothene or vinyl trichloride, is a volatile organochlorine compound. It is a colorless, non-flammable liquid with a sweet odor. TCE has been widely used as an industrial solvent, particularly for degreasing metals and in dry cleaning. Its effectiveness in dissolving oils and greases made it a popular choice for many manufacturing processes.

Historically, TCE also found applications in consumer products, including adhesives, paint removers, and aerosol sprays. However, concerns about its health effects have led to significant restrictions and bans on many of these uses. The primary routes of human exposure have been inhalation of vapors and dermal contact.

TCE is recognized as a human carcinogen. Exposure can lead to a range of health problems affecting the nervous system, liver, and kidneys. Short-term exposure can cause dizziness, headaches, and nausea, while long-term exposure is associated with more severe and chronic health issues. Due to its environmental persistence and potential for groundwater contamination, regulatory bodies worldwide have implemented stringent controls on its production, use, and disposal. Efforts are ongoing to find safer alternatives for its historical applications.
