Perchloroethylene in Outdoor Air by County, New Jersey, 2019

Why Is This Important?

Perchloroethylene (also called tetrachloroethylene), is a colorless liquid widely used for dry cleaning of fabrics. Textile mills, chlorofluorocarbon producers, vapor degreasing and metal cleaning operations, and makers of rubber coatings may also use perchloroethylene. It is also commonly used in aerosol formulations, solvent soaps, printing inks, typewriter correction fluid, adhesives, sealants, shoe polishes and lubricants. Perchloroethylene is a central nervous system depressant. Inhaling its vapors can cause dizziness, headache, sleepiness, confusion, nausea, and unconsciousness. Breathing perchloroethylene over long periods of time can cause liver and kidney damage and memory loss. Perchloroethylene is classified by the International Agency for Research on Cancer as a probable human carcinogen.
