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 concentration of 1.5E6 OH/cm3 is 13.3 days.
Key value for chemical safety assessment
- Half-life in air:
- 13.3 d
Additional 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 concentration of 1.5E6 OH/cm3 is 13.3 days.
The calculated half-life of trichloroethylene due to this reaction is 13.3 days with a OH radical concentration of 1.5E6 OH/cm3 (AOPWIN, 2000), with an overall OH-rate constant of 8.048E-13cm3/molecule.sec. Trichloroethylene also reacts with ozone, nitrogen oxide and chlorine atoms in the atmosphere but this is thought to be an insignificant atmospheric degradation process.
Overall, trichloroethylene is rapidly degraded in the atmosphere.
