Recent research has revealed that exposure to Tetrachloroethylene, a chemical commonly used in dry cleaning and household products, may increase the risk of liver diseases by up to three times.
Tetrachloroethylene
- Tetrachloroethylene is a clear, colorless, volatile liquid with an ether-like smell.
- It is nonflammable and does not dissolve in water.
- It is also known by various names such as perchloroethylene, PCE, perc, tetrachloroethene, and perchlor.
Health Impacts
- Exposure to high concentrations of this chemical can cause adverse health effects, including dizziness, headaches, sleepiness, and in severe cases, unconsciousness or even death.
- Long-term exposure is now linked to liver damage and potential carcinogenic effects.
Environmental Entry and Persistence
- Tetrachloroethylene breaks down very slowly in the atmosphere, allowing it to travel long distances in the air.
- It evaporates quickly from water but degrades slowly in aquatic environments. In soil, it persists for long periods and can seep into the ground, contaminating groundwater.
- Improper disposal, industrial discharge, and factory waste are common sources of environmental contamination, making drinking water a possible exposure route.
Applications
- Widely used in dry cleaning of clothes and textiles.
- Used as a degreasing agent in industrial and household settings to clean metal and machinery.
- Acts as a chemical intermediate in the production of other substances.
- Present in some consumer products, including cleaning agents and adhesives.
Conclusion
Tetrachloroethylene’s widespread use and persistence raise environmental and health concerns, highlighting the need for safer alternatives and stricter regulation.
