Tetrachloroethylene Toxicity
Cover Page

Key Concepts

• Tetrachloroethylene is used mainly as a solvent for dry cleaning and metal degreasing.
• Like most chlorinated solvents, tetrachloroethylene can cause central nervous system depression.
• Chronic exposure to tetrachloroethylene may adversely affect the neurological system, liver, and kidneys.
• Tetrachloroethylene is reasonably anticipated to be a human carcinogen on the basis of limited evidence from studies in humans and sufficient evidence of carcinogenicity from studies in experimental animals.

Disclaimer

The state of knowledge regarding the treatment of patients potentially exposed to hazardous substances in the environment is constantly evolving and is often uncertain.

This monograph is intended as an educational resource for physicians and other health professionals in assessing the condition and managing the treatment of patients potentially exposed to hazardous substances. It is not, however, a substitute for the professional judgment of a health care provider.
