Trichloroethylene and tetrachloroethylene are further metabolized to trichloroethanol and trichloroacetic acid, and oxalic acid and trichloroacetic acid, respectively (Mitoma et al., 1985; Ikeda and Ohtsuji, 1972; Yllner et al., 1971). 45 0 obj <>stream (1) The vapor pressure for tetrachloroethylene is 18.47 mm Hg at 25 °C, and it … Tetrachloroethylene is commonly found in brake cleaners used in workshops. Tetrachloroethylene is widely used as a scouring solvent that removes oils from fabrics, as a carrier solvent, as a fabric finish or water repellant, and as a metal degreaser/cleaner. Tetrachloroethylene breaks down very slowly in the air and so it can be transported long distances in the air. How can families reduce their risk for exposure to tetrachloroethylene? T he production and use of 1,1,1-trichloroethane and carbon tetrachloride have been phased out throughout the world because of suspected harm to the earth's ozone layer. Agency for Toxic Substances and Disease Registry. People working in the dry cleaning industries or using metal degreasing products may be exposed to elevated levels of tetrachloroethylene. What happens to tetrachloroethylene when it enters the environment? This pathway was contributed by Lynda Ellis and Sean Anderson, University of Minnesota.. Tetrachloroethene, also known industrially as perchloroethylene (PCE), is a good solvent used to clean machinery, electronic parts, and clothing.

Linking to a non-federal website does not constitute an endorsement by CDC or any of its employees of the sponsors or the information and products presented on the website. 25 Over a 3-year period, Jeney et al. Trichloroethylene (TCE) is a halogenated aliphatic organic compound which, due to its unique properties and solvent effects, has been widely used as an ingredient in industrial cleaning solutions and as a “universal” degreasing agent. It shows IR transparency as it has no C–H bonds making it an ideal solvent for IR spectroscopy. Tetrachloroethylene evaporates quickly from water into air. People residing near contaminated sites or dry cleaning locations may be exposed to higher levels than the general population. ]�o�o�%�b��7�0�b'2����a�͏�|��w�ش�������M2�4�L��^�7ח�n��&��8��k�e����������~���z9QX���#������;,�������7/Ͽ߿�m�ߝ�$�;>�b�����0��,�����O��k���K��}��kZ�T����R�Tz�B����C�����T{�jmH��04�,���ƣ�b�Ӝ��f�:m�jE(�)��t$;���#���~*9j.
