Tetrachloroethylene (PCE) is a colourless, readily volatile liquid with an ether-like odour. The main industrial applications of PCE are as a dry-cleaning agent, degreaser for fabricated metal parts, and industrial solvent. Other applications include textile finishing, production of printing inks, and formulation of adhesives.

=== '''Predominant sources of emissions''' ===

There are no known natural sources of PCE.
Concerning indoor sources:
-Contaminated drinking water can be a source of indoor exposure to PCE.
- Dry-cleaning workers have become sources of PCE in the home by exhaling it.
- Dry-cleaned laundry is also a possible source of PCE.
- Soil contamination with PCE has led to concentrations of these chemicals in indoor air as they evaporate and can leach through indoor air.

=== '''Legislation and intervals''' ===

According to World Health Organization, the limit value for tetrachloroethylene is 0.25 mg/m3 on an annual average.
