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.
which used and disposed of tetrachloroethylene
(PCE) at the site.
16] and Williams and Peterlin  observed that tensile stress reduces the sorption of n-pentane, benzene, methylene chloride, and tetrachloroethylene
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.
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 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.
The contaminants found in the three ships were industrial solvents identified as di-methy esters of hexanedioic acid, mainly found in thinners, tricholoethylene, used for grease removal in the textile and electronics industry, and tetrachloroethylene
, a drycleaning solvent.
Reuben Sandler, president and chief executive officer of IOS, said, "In phase one of this project, we demonstrated the ability of the smart spectral analysis approach to detect the target contaminants tetrachloroethylene
(PCE) and trichlorethylene (TCE) in isolation and in real-world spectra taken from a mixture of materials obtained from a typical remediation site.
