                • Health Hazard Vapor can affect central nervous system and cause anesthesia. Liquid may irritate skin after prolonged contact. May irritate eyes but causes no injury.
                • Health Hazard Exposure to tetrachloroethylene can produceheadache, dizziness, drowsiness, incoordina tion, irritation of eyes, nose, and throat, and flushing of neck and face. Exposure to highconcentrations can produce narcotic effects.The primary target organs are the centralnervous system, mucous membranes, eyes,and skin. The kidneys, liver, and lungs areaffected to a lesser extent. Symptoms ofdepression of the central nervous system aremanifested in humans from repeated expo sure to 200 ppm for 7 hours/day. Chronicexposure to concentrations ranging from 200to 1600 ppm caused drowsiness, depression,and enlargement of the kidneys and livers inrats and guinea pigs. A 4-hour exposure to4000 ppm of vapor in air was lethal to rats.
                  Ingestion of tetrachloroethylene may pro duce toxic effects ranging from nausea andvomiting to somnolence, tremor, and ataxia.The oral toxicity, is low, however, with LD50ranging between 3000 and 9000 mg/kg inanimals. Skin contact with the liquid maycause defatting and dermatitis of skin.
                  Evidence of carcinogenicity of this com pound has been noted in test animals sub jected to inhalation or oral administration. Itcaused tumors in the blood, liver, and kidneyin rats and mice. Carcinogenicity in humansis not reported.
                • Brandgefahr Special Hazards of Combustion Products: Toxic, irritating gases may be generated in fires.
                • Industrielle Verwendung Perchloroethylene is a member of a family of aliphatic halogenated hydrocarbons. It is a colorless, volatile liquid that is essentially nonflammable and has no measurable flash point. It is the primary solvent used in commercial and industrial dry cleaning. Since being introduced to the dry cleaning industry in the late 1930s, it has replaced most other solvents because of its relatively low toxicity and nonflammability. Its other major uses are as a metal cleaning and degreasing solvent, as a solvent in automotive aerosols, and as a chemical intermediate in the production of several fluorinated compounds. The use of perchloroethylene can be broken down into the following categories:
                  chemical intermediate (~50%)
                  dry cleaning/textile processing (~25%)
                  automotive aerosols (~10%)
                  metal cleaning/degreasing (-10%)
                  miscellaneous (-5 %)
                  Perchloroethylene is used as a basic raw material in the manufacture of hydrofluorocarbon (HFC) 134a, a popular alternative to chlorofluorocarbon (CFC) refrigerants. It also is used in the synthesis of hydrochlorofluorocarbon (HCFC) 123 and 124 and HFC 125.
                  Perchloroethylene is used by more than 80 percent of commercial dry cleaners, as well as some industrial cleaning establishments. It had replaced other synthetic solvents, such as carbon tetrachloride. The textile industry uses perchloroethylene as a spotting agent for the removal of spinning oils and lubricants. It also is used in wool scouring and as a solvent carrier in dyes and water repellents.
                • Anticancer Research PERK, a transmembrane protein, phosphorylates eIF2-alpha which inhibits the synthesisof new proteins and folding of the existing proteins. In addition, the activatingtranscription factor 4 (ATF4) expression is selectively induced by eIF2α phosphorylation,which induces upregulation of UPR genes and growth arrest, including ERoxidoreductase1α, CCAAT/enhancer-binding protein-homologous protein (CHOP)and various pro-apoptotic factors (Quick and Faison 2012; Carreras et al. 2017).Haem-regulated eIF2α kinase and multiple kinases including protein kinase R alsoinduce eIF2α phosphorylation. The integrated stress response (ISR) is referred to assignalling related to eIF2α phosphorylation. Nuclear factor (erythroid-derived2)-like 2 (Nrf-2) is another substrate which upon phosphorylation dissociates fromits cytoskeletal anchor and goes and binds to antioxidant redox element (ARE) inthe nucleus. It has twofold part to play in cancer, oncogenic function and tumoursuppressor function depending upon the ER stress in the cell. In normal circumstances,Nrf-2 interacts with kelch-like ECH-associated protein I to preserve theinactive state in the cytoplasm. PERK dissociates phosphorylated Nrf-2 from kelchlikeECH-associated protein I, which results in its translocation from membrane tothe nucleus and antioxidant genes getting expressed promoting cell survival.
                  For survival of the tumour during nutrient starvation and hypoxia, it is considerednecessary for the ISR and PERK signalling to get activated. Reactive oxygenspecies (ROS) concentration is increased as a result of oxidative stress and hypoxia.Additionally, PERK signalling upregulates ER oxidoreductase1α that controls ERredox status. As notified in different kinds of cancers, due to upsurge in the levels ofROS in tumours, ER oxidoreductase 1α is overexpressed (Wang et al. 2014).Inhibition of ISR or PERK signalling causes production of ROS that restricts growthof tumour by means of oxidative DNA damage. Retorting to prolonged and intenseER stress, cell death is induced by CHOP, a transcription factor and a downstreamtarget of ATF4 (Hiramatsu et al. 2014). Hence there are possibilities of ISR andPERK being the therapeutic targets for cancer on account of their dual role insignalling pathways (Farooqi et al. 2015).

                • m?gliche Exposition Tetrachloroethylene is used in the textile industry and as a chemical intermediate or a heatexchange fluid; a widely used solvent with particular use as a dry cleaning agent; a degreaser; a fumigant, and medically as an anthelmintic.
                • Carcinogenicity Tetrachloroethylene is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
                • Environmental Fate Biological. Sequential dehalogenation by microbes under laboratory conditions produced trichloroethylene, cis-1,2-dichloroethylene, trans-1,2-dichloroethylene, and vinyl chloride (Smith and Dragun, 1984). A microcosm composed of aquifer water and sediment collected from uncontaminated sites in the Everglades biotransformed tetrachloroethylene to cis- and trans-1,2- dichloroethylene (Parsons and Lage, 1985). Microbial degradation to trichloroethylene under anaerobic conditions or using mixed cultures was also reported (Vogel et al., 1987).
                  Surface Water. Estimated half-lives of tetrachloroethylene (3.2 μg/L) from an experimental marine mesocosm during the spring (8–16 °C), summer (20–22 °C), and winter (3–7 °C) were 28, 13, and 15 d, respectively (Wakeham et al., 1983).
                  Photolytic. Photolysis in the presence of nitrogen oxides yielded phosgene (carbonyl chloride) with minor amounts of carbon tetrachloride, dichloroacetyl chloride, and trichloroacetyl chloride (Howard, 1990). In sunlight, photolysis products reported include chlorine, hydrogen chloride, and trichloroacetic acid. Tetrachloroethylene reacts with ozone to produce a mixture of phosgene and trichloroacetyl chloride with a reported half-life of 8 d (Fuller, 1976). Reported photooxidation products in the troposphere include trichloroacetyl chloride and phosgene (Andersson et al., 1975; Gay et al., 1976; U.S. EPA, 1975). Phosgene is hydrolyzed readily to hydrogen chloride and carbon dioxide (Morrison and Boyd, 1971).
                  Chemical/Physical. The experimental half-life for hydrolysis of tetrachloroethylene in water at 25 °C is 8.8 months (Dilling et al., 1975).

                • l?uterung methode It decomposes under similar conditions to CHCl3, to give phosgene and trichloroacetic acid. Inhibitors of this reaction include EtOH, diethyl ether and thymol (effective at 2-5ppm). Tetrachloroethylene should be distilled under a vacuum (to avoid phosgene formation) and stored in the dark out of contact with air. It can be purified by washing with 2M HCl until the aqueous phase no longer becomes coloured, then with water, drying with Na2CO3, Na2SO4, CaCl2 or P2O5, and fractionally distilling just before use. 1,1,2-Trichloroethane and 1,1,1,2-tetrachloroethane can be removed by counter-current extraction with EtOH/water. [Beilstein 1 IV 715.]
                • Inkompatibilit?ten Violent reaction with strong oxidizers; powdered, chemically active metals, such as aluminum, lithium, beryllium, and barium; caustic soda; sodium hydroxide; potash. Tetrachloroethylene is quite stable. However, it reacts violently with concentrated nitric acid to give carbon dioxide as a primary product. Slowly decomposes on contact with moisture producing trichloroacetic acid and hydrochloric acid. Decomposes in UV light and in temperatures above 150℃, forming hydrochloric acid and phosgene.
                • Waste disposal Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. Incineration, preferably after mixing with another combustible fuel. Care must be exercised to assure complete combustion to prevent the formation of phosgene. An acid scrubber is necessary to remove the halo acids produced. Alternatively, PCE may be recovered from waste gases and reused.
