Description of key information

Additional information

Chloroethyleneis a highly volatile substance which is difficult to test for biodegradation in the experimental systems. The estimated QSARs data on environmental degradation ofchloroethyleneare summarized in table below.

Overall, the QSAR estimated data suggest that this substance will degrade fast in the environment.


Table Degradation rates of chloroethylene


Degradation rate in water:

Abiotic transformation:

Hydrolysis is not a relevant degradation route for the substance.


Biotic transformation:

DT50=15 days (360 hours)


Degradation rate in sediment:

DT50=135days (3240 hours)

Degradation rate in soil:

DT50=30 days (720 hours)

Degradation rate in air:

DT50=1.45 days (35.74 hours)

DT50 (for reaction with hydroxyl radicals)= 1.937 days (23.240 hours)


Based on the data summarized in this section of CSR,chloroethylene is considered to degrade rapidly via abiotic or biotic degradation paths.
