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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Using ECOSAR, the 96-h EC50 is estimated to be 77 mg/l in aquatic algae
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 77 mg/L
Additional information
Due to the fact that vinyl chloride is a gas, no significant concentrations are present in the fresh water and seawater compartment. This is supported by exposure assessment with EUSES. A regional PEC in fresh surface water of 4.18E-06 mg/L and a regional PEC in seawater of 3.44E-07 mg/L were calculated. The maximal local PEC value that was calculated for fresh water was 3.65E-02 mg/L (for S-PVC production). The maximum local PEC value that was calculated for seawater was 3.65E-03 mg/L (for S-PVC production). Since these concentrations are very low, no significant exposure of algae is assumed and therefore short term toxicity tests with algae are not considered necessary.
Only a QSAR value is available for short-term toxicity in aquatic algae. This value will be used in the assessment.
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.
