Tetrachloroethylene (Cl₂C=CCl₂) is a colorless liquid with a mild, chloroform-like odor. Tetrachloroethene is found in consumer products, including some paint and spot removers, water repellents, brake and wood cleaners, glues, and suede protectors. Tetrachloroethylene is a colourless liquid solvent. September 2015 Tetrachloroethylene What is tetrachloroethylene? Exposure to very high concentrations of tetrachloroethylene can cause dizziness, headaches, sleepiness, confusion, nausea, difficulty in speaking and walking, unconsciousness, and death. The two carbons are linked with each other by a double chemical bond. the effects on human health of the substances or contaminants examined in drinking- ... in its Environmental Health. The most sensitive target for tetrachloroethylene-induced cancer is an immune cell type, mononuclear cell leukemia. Aerosol paints, agricultural chemicals, automotive chemicals, furniture polish and cleaners, hard surface cleaners, rug carpet and upholstery cleaners, lubricating greases and oils, paint and varnish removers and thinners, textile finishes, typewriter correction fluids and waterproofing compounds. In high concentrations, in air, with closed or poorly ventilated areas, single exposures to tetrachloroethylene may cause central nervous system effects leading to dizziness, headache, sleepiness, confusion, nausea, difficulty in speaking or walking, and possibly unconsciousness and death. It is a narcotic at high levels. It will also defat the skin causing irritation and dryness. humans. - Disclaimer / Terms of Use / Privacy Policy, consumer products (e.g., shoe polish, typewriter correction fluid). In contrast, the dissolved PCE phase will travel with groundwater. Safe Work Australia, Workplace exposure standards for airborne contaminants, accessed March 2019. This means that PCE evaporates (goes from liquid into gaseous form when in contact with air). Sheffer, Marla. It has moderate chronic (long-term) toxicity to aquatic life. Background: The U.S. Environmental Protection Agency (EPA) completed a toxicological review of tetrachloroethylene (perchloroethylene, PCE) in February 2012 in … Non-Cancer EffectsExposure to PCE may cause a variety of health effects depending on the amount of PCE and exposure time. Skin irritation 2. Despite its toxicity, it is an extremely effective, quick drying and non-flammable solvent. Through skin absorption (please note that PCE is not efficiently absorbed through the skin): Through breast feeding – since PCE accumulates in milk due to its lipophilic nature. Chronic and acute effects on plants, birds or land animals have not been determined, but appear to be low. include the following guidelines for acceptable water quality: Tetrachloroethylene will exist as a gas if released to the atmosphere. These are emissions to the air unless there is a spill. Acute Effects: Central nervous system effects are the primary effects noted from acute inhalation exposure to trichloroethylene in humans, with symptoms including sleepiness, fatigue, headache, confusion, and feelings of euphoria. In the soil and water bacteria will break it down, very slowly. Tetrachloroethylene has been found in at least 771 of the 1,430 National Priorities List sites identified by the Environmental Protection Agency (EPA). Several occupational and environmental studies in humans have reported a statistically significant association with exposure to tetrachloroethylene and leukemia. Although not theoretically impossible, there is no evidence that PCE forms or occurs naturally in the environment. However, PCE does not strongly sorb to soil. Safe Work Australia sets the PCE is an organic chemical introduced in the environment by human activity. Synonyms: Perchloroethylene; PERK; PERC; Ethylene tetrachloride; tetrachloroethene; 1,1,2,2-tetrachloroethylene; carbon dichloride; perchlor; tetrachloroethane; carbon bichloride; perk. The concentration of tetrachloroethylene in the tissues of fish are expected to be somewhat higher than the concentration of tetrachloroethylene in the water from which the fish was taken. In the air it is reacted into other chemicals, in several weeks. It also evaporates from soil and water when they are exposed to the air. It may also cause liver damage and is a potential occupational carcinogen. Integrated Risk Information System (IRIS) U.S. Environmental Protection Agency Chemical Assessment Summary National Center for Environmental Assessment 5 define the exposure-response relationships in humans. Tetrachloroethylene does bioaccumulate to a limited extent. Australian Drinking Water Guidelines As a solvent or as a component of solvent blends trichloroethylene is used with adhesives, lubricants, paints, varnishes, paint strippers, pesticides, and cold metal cleaners.
