Occupational exposure to tetrachloroethylene occurs primarily through inhalation and dermal contact with this compound at workplaces where tetrachloroethylene is produced or used.
The general population may be exposed to tetrachloroethylene via inhalation of ambient air, ingestion of food and drinking water.
Dermal contact also may be a route of tetrachloroethylene exposure in the workplace and among the general public. However, the chemical is less easily absorbed through the skin than through inhalation and oral exposure routes.
