Perchloroethylene intoxication.

Perchloroethylene White Paper - Novermber 2008

Perchloroethylene, also known as tetrachloroethylene or perc, has been used safely in industry for over 50 years. It is an effective, nonfl ammable solvent that does not contribute to the formation of smog (ground-level ozone) or to the depletion of stratospheric ozone. The US Environmental Protection Agency (EPA) has approved the use of perchloroethylene as a replacement for stratospheric ozon...

Perchloroethylene Inhalation Cancer Unit Risk Factor

Hepatic and renal toxicities associated with perchloroethylene.

Metabolism of perchloroethylene (Perc) occurs by cytochrome P450-dependent oxidation and glutathione (GSH) conjugation. The cytochrome P450 pathway generates tri- and dichloroacetate as metabolites of Perc, and these are associated with hepatic toxicity and carcinogenicity. The GSH conjugation pathway is associated with generation of reactive metabolites selectively in the kidneys and with Perc...

Spontaneous abortion in dry cleaning workers potentially exposed to perchloroethylene.

OBJECTIVES To investigate the association between spontaneous abortion and work within dry cleaning units in the United Kingdom where the solvent perchloroethylene is used. METHODS A retrospective occupational study of reproductive outcome in 7305 women aged 16 and 45 years, who were currently or previously employed in dry cleaning or laundry units in the United Kingdom. Data on workplace exp...

A New Electron Donor for Reductive Dechlorination of Perchloroethylene

One of the main problems associated with remediation of chlorinated solvent groundwater contamination is the presence of NAPLs in the source zone. NAPLs are often better treated through solvent extraction, surfactant washing, or vapor extraction than through bioremediation. Removal of NAPL through solvent extraction would likely leave a substantial residual of both the extraction solvent and th...
