Context: In March 2024, the U.S. Environmental Protection Agency (EPA) proposed a ban on TCE due to its severe health risks.
Trichloroethylene (TCE) and Perchloroethylene (PCE) are chlorinated solvents widely used in industrial applications, particularly for degreasing metals, dry cleaning, and chemical manufacturing. However, both chemicals are known to pose serious health and environmental risks.
Trichloroethylene (TCE): Used as a solvent for cleaning metal parts and as an ingredient in adhesives and paint removers. It is classified as a carcinogen and has been linked to liver, kidney, and immune system damage.
Perchloroethylene (PCE): Commonly used in dry cleaning and as a degreasing agent. Long-term exposure has been associated with neurological issues, cancer, and environmental contamination.
