Further information on the physical and chemical properties of trichloroethylene can be found in Chapter 3, and further information on its production and use can be found in Chapter Size: 4MB. The greatest use of trichloroethylene is to remove grease from fabricated metal parts and some textiles. The list of trade names given below may help you find out whether you are using this chemical at home or work. Trade Names and Synonyms: 1,1,2-Trichloroethylene Acetylene trichloroethylene Algylen Anameth Benzinol Chlorilen CirCosolv Germalgene.

    Trichloroethylene (TCE) is a chlorinated volatile organic compound (CVOC), used in the last years in dry-cleaning applications and as degreasing agent. In this study we report on the catalytic oxidation of gaseous trichloroethylene (TCE), in a fixed bed reactor, performed by using mayenite (Ca 12 Al 14 O 33) synthetized by using the ceramic Cited by: 3. Effects of long-term or repeated exposure Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the central nervous system. This may result in fatigue, irritability and mental and memory disturbances. The substance may have effects on .

HEALTH EFFECTS OF TRICHLOROETHYLENE Human Exposure. Trichloroethylene is a common environmental contaminant at Superfund sites, Department of Defense facilities, and certain manufacturing operations (e.g., aircraft, spacecraft).

It has been found at approximately of the 1, sites proposed forFile Size: 45KB. The investigators concluded that, although the effects observed were not remarkable, the immune system does appear to be sensitive to the chemical (Sanders, Tucker et al.

A few reports have been found on human immunological abnormalities related to usage of TCE contaminated well water (Agency for Toxic Substances and Disease Registry ). Trichloroethylene, a colourless, toxic, volatile liquid belonging to the family of organic halogen compounds, nonflammable under ordinary conditions and used as a solvent and in adhesives.

Trichloroethylene has a subtle, sweet odour. Trichloroethylene was first prepared in ; its commercial manufacture, begun in Europe inis based on the reaction of 1,1,2,2-tetrachloroethane with.

If trichloroethylene is burning use: carbon dioxide, dry chemical powder, appropriate foam, water spray or fog. Specific Hazards Arising from the Chemical: Vapour may accumulate in hazardous amounts in low-lying areas especially inside confined spaces, resulting in a toxicity hazard.

The chemical formula for trichloroethylene is C2HCl3, and the molecular weight is g/mol. (1) The vapor pressure for trichloroethylene is 74 mm Hg at 25 °C, and it has a log octanol/water partition coefficient (log Kow) of (1) Trichloroethylene is not a persistent chemical in the atmosphere; its half-life in air is about 7 days.

Immunotoxicity. As recently reviewed by Cooper et al. () and documented in the TCE assessment (U.S. EPA d), the human and laboratory animal studies of TCE and immune-related effects provide strong evidence that TCE exposure increases the risk of autoimmune disease and a specific type of generalized hypersensitivity syndrome.

Page and Jack L. Arthur; Consideration of the target organ toxicity of trichloroethylene in terms of metabolite toxicity and phar. Acute (short-term) exposure to TCE vapors can cause central nervous system (CNS) effects (e.g., light-headedness, drowsiness, headache and giddiness) and may lead to unconsciousness or be fatal.

At very high exposure levels, TCE can sensitize the heart to the effects of adrenaline and similar agents, which may lead to sudden cardiac arrest. Respiratory effects of trichloroethylene. Belonging to the chemical group of chlorinated aliphatic solvents, TCE has been used in multiple industries as an industrial solvent, an extractant in.

H.M. Mehendale, in Comprehensive Toxicology, Trichloroethylene (Trichloroethene) Trichloroethylene, a common industrial solvent used for degreasing metals, is produced in the United States at about metric tons per year.

In addition to being present at industrial sites, trichloroethylene is a contaminant at many chemical waste sites. We reviewed evidence for respiratory effects of trichloroethylene (TCE) exposure.

• Evidence of a higher risk of lung cancer associated with TCE exposure is limited. • Few data are available on the association of TCE with asthma or chronic bronchitis.

• TCE has been linked to systemic sclerosis and pulmonary veno-occlusive by: Enhancing effects of trichloroethylene and tetrachloroethylene on type I allergic responses in mice. Seo M, Kobayashi R, Okamura T, Ikeda K, Satoh M, Inagaki N, Nagai H, Nagase H.

Trichloroethylene (TCE) and tetrachloroethylene (perchloroethylene; PCE) are commonly identified as environmental contaminants of by: 4. The Chemical Identifier fields include common identification numbers, the NFPA diamond U.S.

Department of Transportation hazard labels, and a general description of the chemical. The information in CAMEO Chemicals comes from a variety of data sources. Abstract. The thermal treatment of TiO 2 pellets prepared by the sol–gel method decreased the photocatalytic activity.

The activity divided by the specific surface area of the pellets for the complete mineralization of ethylene or chloroform was maximized at the firing temperature of ° by: 6. The chemical compound trichloroethylene is a halocarbon commonly used as an industrial is a clear non-flammable liquid with a sweet smell.

It should not be confused with the similar 1,1,1-trichloroethane, which is commonly known as chlorothene. The IUPAC name is rial abbreviations include TCE, trichlor, Trike, Tricky and iations: TCE.

One chlorinated solvent, trichloroethylene (TCE), has been getting a lot of attention, and it is estimated to be present in 34 percent of the nation’s drinking water supplies. TCE possesses unique physical and chemical properties that pose serious health risks and make.

Trichloroethylene or TCE (Cl 2 C=CHCl) is a clear, colorless, nonflammable liquid possessing a sweet, fruity odor characteristic of chloroform. The odor threshold is approximately 20 to 80 parts per million (ppm). For some workers, TCE’s odor may not be detectable at concentrations near the permissible workplace exposure limit of 50 ppm (as determined by an 8-hour time-weighted average), and.Undesired exothermic reactions initiated during production, purification or storage by excessive temperatures or other causes have similar destructive effects, even if the origin is different.

Although the hazards connected with exothermic reactions have been known since the inception of the chemical industry, a systematic knowledge of the Cited by: The Health Risks of Trichloroethylene Trichloroethylene (TCE) is a widely used cleaner at factories, military bases and hundreds of waste sites around the world.
