Trichloroethylene

Formula: C₂HCI₃ | CAS: 79-01-6

Trichloroethylene detection: Trichloroethylene, also known as TCE, is a colourless, volatile liquid that is produced in large volumes for commercial use.

Identifying Trichloroethylene detection early to limit exposure dangers

Trichloroethylene may be found in the air, water, and soil at places where it is produced or used. It breaks down slowly and remains in the environment for a long time. It readily passes through soil and can accumulate in groundwater.

People in the general population can be exposed to trichloroethylene by inhaling it in indoor and outdoor air, drinking contaminated water, or eating foods that have been washed or processed with contaminated water. Because this chemical was used extensively by the US military to degrease equipment, contaminated soil and groundwater can be found near many current and former military bases.

Trichloroethylene was once used as an anaesthetic for surgery. People who are overexposed to moderate amounts of trichloroethylene may experience headaches, dizziness, and sleepiness; large amounts of trichloroethylene may cause coma and even death. Some people who breathe high levels of trichloroethylene may develop damage to some of the nerves in the face. Other effects seen in people exposed to high levels of trichloroethylene include evidence of nervous system effects related to hearing, seeing, and balance, changes in the rhythm of the heartbeat, liver damage, and evidence of kidney damage. Some people who get concentrated solutions of trichloroethylene on their skin develop rashes.

Levels of trichloroethylene detection in the environment

Workers and employers should practice good occupational health behaviours, which may include wearing protective gear and properly using respirators, and reducing exposure time to TCE. Everyone should avoid drinking water known to
be contaminated with TCE. Children should be prevented from playing in areas where TCE has been found in the soil. Always follow instructions on product labels to minimise exposure to harmful chemicals.
