Trichloroethylene: environmental and occupational exposure.
Trichloroethylene is used in paint strippers, rug cleaners, spot removers, typewriter correction fluid and industrial cleaners. It is a common environmental contaminant, detected in over one-third of hazardous waste sites and in 10 percent of groundwater sources. Acute workplace exposure above acceptable levels can cause neurologic, respiratory and hepatic problems. The health effects of prolonged occupational and environmental low-level exposure are probably minimal, but whether such exposure poses a risk remains controversial. Although trichloroethylene has been shown to cause cancer in some animals, it has not been proven to be a human carcinogen. Trichloroethylene has been involved in several well-publicized cases of contamination of community water supplies, and family physicians are likely to receive questions about this chemical.
