Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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 aquatic invertebrates is assumed and therefore short term toxicity tests with aquatic invertebrates are not considered necessary.

Multiple tests with fish demonstrate a low aquatic toxicity. ECOSAR calculations indicate that there is no significant difference in sensitivity between fish and aquatic invertebrates for vinyl chloride.

Only a QSAR value is available for short-term toxicity in invertebrates. This value will be used in the assessment.
