In homes, trichloroethylene can be found in
typewriter correction fluid, paint, spot removers, carpet-cleaning fluids, metal cleaners, and varnishes
. Trichloroethylene also is known as trichloroethene, and is commonly referred to as TCE. Regulation of TCE by the EPA began in the 1980s.
Where is trichloroethylene used?
It is used primarily to
make refrigerants and other hydrofluorocarbons
and as a degreasing solvent for metal equipment. TCE is also used in some household products, such as cleaning wipes, aerosol cleaning products, tool cleaners, paint removers, spray adhesives, and carpet cleaners and spot removers.
What products is trichloroethylene found in?
- adhesives.
- cleaning fluids for rugs.
- paint removers/strippers.
- spot removers, spot removers.
- typewriter correction fluids.
What is trichloroethylene commonly known as?
The chemical compound trichloroethylene is a halocarbon commonly used as an industrial solvent. It is a clear, colourless non-flammable liquid with a chloroform-like sweet smell. It should not be confused with the similar 1,1,1-trichloroethane, which is commonly known as
chlorothene
. The IUPAC name is trichloroethene.
Is trichloroethylene a human carcinogen?
The Department of Health and Human Services (DHHS) considers trichloroethylene to
be a known human carcinogen
. The International Agency for Research on Cancer (IARC) classified trichloroethylene as carcinogenic to humans.
Is trichloroethylene harmful to the body?
A recent analysis of available epidemiological studies reports trichloroethylene exposure to be associated with several types of
cancers
in humans, especially kidney, liver, cervix, and lymphatic system. Animal studies have reported increases in lung, liver, kidney, and testicular tumors and lymphoma.
Is TCE still used today?
The chemical, trichloroethylene (or TCE) has long been used for degreasing and cleaning metal parts in factories, but has been
classified a “human carcinogen
” by the Environmental Protection Agency since 2011.
When was Trichloroethylene banned?
Fetal toxicity and concerns for carcinogenic potential of TCE led to its abandonment in developed countries by the 1980s. The use of trichloroethylene in the food and pharmaceutical industries has been banned in much of the world
since the 1970s
due to concerns about its toxicity.
How do you remediate TCE?
Approaches applied to the remediation of TCE and other DNAPLs include bioremediation, electrokinetics, flushing technologies (cosolvent/alcohol flooding, surfactant flushing), in situ oxidation, monitored natural attenuation, phytoremediation, (steam injection, electrical heating, in situ vitrification), volatilization …
How does Trichloroethylene affect the environment?
Environmental Hazards
Because of its high vapor pressure and low rate of adsorption in soil TCE
evaporates fairly rapidly when released to soil
. However, where it persists it can percolate rapidly through sandy soil thereby reaching groundwater.
How is Tetrachloroethylene made?
Most tetrachloroethylene is produced
by high temperature chlorinolysis of light hydrocarbons
. The method is related to Faraday’s discovery since hexachloroethane is generated and thermally decomposes. Side products include carbon tetrachloride, hydrogen chloride, and hexachlorobutadiene.
What industries use TCE?
TCE is used as a degreasing solvent in the
metal finishing, automotive and aerospace industries
. TCE is an important solvent for degreasing soft metals such as aluminum and works well cleaning steel before galvanizing.
How does Trichloroethylene get into water?
Trichloroethylene can
enter drinking water through leaks, evaporation and spills from industrial storage tanks
. … Trichloroethylene is measured in parts per billion (ppb). The federal government has established the safe drinking water standard (also called maximum contaminant level) for trichloroethylene as 5 ppb.
Is Trichloroethylene a toxic chemical?
HEALTH HAZARD
EPA classifies TCE
as carcinogenic to humans
by all routes of exposure. EPA has found that TCE has the potential to induce neurotoxicity, immunotoxicity, developmental toxicity, liver toxicity, kidney toxicity, and endocrine effects.
Does Trichloroethylene cause Parkinson’s disease?
A novel study in twins found that exposure to trichloroethylene (TCE) — a hazardous organic contaminant found in soil, groundwater, and air — is significantly associated with increased risk of Parkinson’s disease (PD).
Why is Trichloroethylene toxic?
TCE is
carcinogenic to humans by all routes of exposure
and poses a potential human health hazard for noncancer toxicity to the central nervous system, kidney, liver, immune system, male reproductive system, and the developing embryo/fetus.
