Description of key information

The log Koc of 1,1-dichloroethene ranges between 1.5027 and 1.8482 L/kg. The average log Koc value was 1.72, i.e. a Koc value of 52.

Key value for chemical safety assessment

Koc at 20 °C:
52

Additional information

The log Koc of 1,1-dichloroethene ranges between 1.5027 and 1.8482 L/kg. According to chapter R.7.8.7 of the Guidance on information requirements and chemical safety assessment, a substance with a Koc in this range can be considered as not likely to be adsorbed to sediment. A log Koc or log Kow of3 is used as a trigger value for sediment effects assessment..
