Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Applicant's summary and conclusion

Conclusions:
The data on environmental distribution of trichloroethylene obtained from the level III fugacity model confirms that trichloroethylene does not degrade fast and depending on various emission scenarios, most of trichloroethylene will be physically removed (advected) from the environment.
