Description of key information
Trichloroethylene undergoes reactions with hydroxyl radicals in the atmosphere.
The half life of trichloroethylene due to this reaction, based on a 12-hr day with a OH radical concentartion of 1.5E6 OH/cm3 is 13.3 days.
Hydrolysis is not expected to be an important removal process for trichloroethylene.
Degradation of trichloroethylene in water by hydrolysis is very slow, with half-lives reported in the range from 10.7 months to 1.3 million years.
Photolysis is not likely to be a significant removal process for trichloroethylene.
Trichloroethylene (1 mg/l) in water was degraded by 52-56% after one year in the dark and by 70-79% in the presence of sunlight.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
