Trichloroethylene (TCE): Overview and Uses
Trichloroethylene (TCE) is a colorless, non-flammable liquid with a sweet odor, widely used as an industrial solvent. It’s known for its effectiveness in degreasing metal parts, making it valuable in manufacturing and maintenance operations. TCE is also used in the production of refrigerants and as an intermediate in chemical synthesis.
Health and Environmental Concerns
TCE is classified as a hazardous air pollutant and a human carcinogen. Long-term exposure can lead to serious health issues, including liver, kidney, and nervous system damage. It’s also associated with an increased risk of cancer, particularly kidney cancer. Due to its volatility, TCE can easily evaporate and contaminate the air, contributing to both indoor and outdoor air pollution. It can also infiltrate groundwater, leading to environmental contamination.
Regulation and Safety Measures
Due to its health risks, the use of TCE has been increasingly regulated. In many countries, there are strict guidelines on its handling, disposal, and permissible exposure limits in the workplace. Alternatives to TCE are being sought in various industries, and where its use is still necessary, stringent safety protocols are implemented to protect workers and the environment.
