Tetrachloroethylene, also known as perchloroethylene [a] or under the systematic name tetrachloroethene, and abbreviations such as perc (or PERC), and PCE, is a chlorocarbon with the formula Cl 2 C=CCl 2. It is a non-flammable, stable, colorless and heavy liquid widely used for dry cleaning of fabrics.
The chemicals — trichloroethylene and perchloroethylene (PCE or perc) — can cause multiple kinds of cancers and damage to the kidney, liver and immune and nervous systems at high exposure ...
This superfund site consists of two dangerous chemical compounds, trichloroethylene (TCE) and perchloroethylene (PCE). Both consist of very harmful toxins that have long term effects on the central nervous system. PCE is generally used for dry cleaning fabrics and decreasing metals, while TCE is typically used as an industrial solvent. [2]
It is dangerous from both inhalation and dermal exposure and was most strongly associated with immunosuppressive effects for acute exposure, as well as autoimmune effects for chronic exposures. [50] Chronic exposure to trichloroethylene has also been linked to an increased risk of Parkinson's Disease.
The density of perchloroethylene is around 1.62 g/cm 3 at room temperature (62% heavier than water), and the sheer weight of absorbed solvent may cause the textile to fail under typical forces during the spin extraction cycle, unless the mesh bag provides mechanical support. Not all stains can be removed by dry cleaning. Some need to be treated ...
