Description

Application:

  • Tetrachloroethylene (PCE) is also known as perchloroethylene, tetrachloroethene, and 1,1,2,2- tetrachloroethene and is also commonly abbreviated to PER or PERC. Tetrachloroethylene is a volatile, chlorinated organic hydrocarbon that is widely used as a solvent in the dry-cleaning and textile-processing industries and as an agent for degreasing metal parts. It is an environmental contaminant that has been detected in the air, groundwater, surface waters, and soil.
  • Tetrachloroethylene is used as a solvent, in drycleaning, and in metal degreasing. Tetrachloroethylene is a common industrial solvent that is often found as a contaminant in groundwater. Tetrachloroethylene is also a suspected carcinogen to humans and is difficult to degrade biologically as it has no natural source. This compound is a contaminant of emerging concern.

Safety Profile

Tetrachloroethylene is a nonflammable colorless liquid with a sharp sweet odor. Tetrachloroethylene is widely used for dry-cleaning fabrics and metal degreasing operations. Effects resulting from acute (short term) high-level inhalation exposure of humans to tetrachloroethylene include irritation of the upper respiratory tract and eyes, kidney dysfunction, and neurological effects such as reversible mood and behavioral changes, impairment of coordination, dizziness, headache, sleepiness, and unconsciousness. The primary effects from chronic (long term) inhalation exposure are neurological, including impaired cognitive and motor neurobehavioral performance. Tetrachloroethylene exposure may also cause adverse effects in the kidney, liver, immune system and hematologic system, and on development and reproduction. Studies of people exposed in the workplace have found associations with several types of cancer including bladder cancer, non-Hodgkin lymphoma, multiple myeloma. U.S. EPA has classified tetrachloroethylene as likely to be carcinogenic to humans.
