Apartment residents' and day care workers' exposures to tetrachloroethylene
and deficits in visual contrast sensitivity.
9 when occupational exposure to either trichloroethylene or tetrachloroethylene
- also known as perchloroethylene (PERC) - was considered as a combined variable, but this too had a wide confidence interval of 1.
2003, "Reductive dechlorination of carbon tetrachloride and tetrachloroethylene
by zerovalent silicon-iron reductants," Environ.
The full report, "Review of the Environmental Protection Agency's Draft IRIS Assessment of Tetrachloroethylene
," is available at www.
Tests were conducted for VOCs including hexane, decane, toluene, tetrachloroethylene
, 2-butanone, isobutanol, and D-limonene.
which used and disposed of tetrachloroethylene
(PCE) at the site.
Some countries also called for discharges of synthetic substances such as trichloroethylene and tetrachloroethylene
to be included in annex I.
Groundwater contaminants include many different industrial and agricultural chemicals and fuels, including a host of other petroleum hydrocarbons; a wide range of chlorinated compounds such as tetrachloroethylene
(PCE), perchlorate and vinyl chloride (PC), carbon tetrachloride, pesticides and industrial solvents; and a long list of metals including arsenic, mercury, lead, chromium and others.
More than 10 years ago, a 2000 gpm carbon removal system was installed to remove volatile organic compounds--trichloroethylene, tetrachloroethylene
, and carbon tetrachloride--and other organics from the system.
Iron particles have already been trialled for the treatment of contaminated groundwater at Port Botany in Sydney where a large iron particle barrier has been installed to destroy chlorinated solvents including 1,2-dichloroethane and tetrachloroethylene
Among the VOCs that Adgate and his team studied were chloroform, a by-product of chlorination that's released from household water; d-limonene and a- and b-pinene, common deodorizing chemicals that produce scents of lemon and pine; para-dichlorobenzene, an air freshener and pesticide; and tetrachloroethylene
, which emanates from dry-cleaned clothing.
The 11 solvents which would be precluded from landfill disposal are: benzene, carbon tetrachloride, chlorobenzene, cresols, MEK, trichloroethylene, 2-nitropropane, nitrobenzene, pyridine, tetrachloroethylene
and methylene chloride.
The acid transport properties are compared with the transport of water and tetrachloroethylene
in order to reveal possible differences between acid and non-acid transport.
The city also detected harmful substances in the soil in the area, including tetrachloroethylene
exceeding standards by 1,800 times and dioxin at 86 times the standard.
is used as a cleaning agent, and it's thought to cause cancer.
